Hard disk error is shown. What can I do? 

1. The message “disk drive x failed or is unplugged” is shown in Event Log. 

2. The message “disk drive x failed or is unplugged” is shown on the LCD 

panel. 

3. Abnormal disk message shown in hard disk configuration under 

administrator mode, e.g. “no disk”. 

Note: Please inform your customers that some data may not be 

recovered due to different status of disk damage. 

Solution: 

1. RAID 1 and RAID 5 configuration: Turn off the system and replace the 

damaged disk(s). NAS will perform disk recovery when the system 

restarts. The system can run properly and all data can be used again. 

Note: It is recommended to replace the damaged disk with new one of 

the same model. 

2. Single disk volume: Turn off the system and replace the damaged disk 

after the system restarts. When the NAS restarts, launch the web 

browser, e.g. IE 6/7, and login the system. Go to Disk Configuration page 

to configure the disk volume. Note that only the data on other three disks 

can be reserved. 

3. JBOD and RAID 0: Turn off the system and replace the damaged disk. 

When the NAS restarts, launch the web browser, e.g. IE 6/7, and login 

the system. Go to Disk Configuration page to configure the disk volume. 

Note that the data on the damaged disk cannot be recovered. 

▲Back 

Can I upgrade the memory of my NAS? 

No, this will void the warranty of your NAS. 

Besides, the memory of some models is soldered to the main board. 

Thus, it’s not possible to replace or insert new memory to the NAS. 

▲Back 

Maintenance steps. 

1. Unfasten the screws on the disk tray. 

2. Take out the disk tray. 

3. Check if any disk is damaged. (Unplug the possible damaged disk and 

insert to other machine for examination.) 

4. Replace the damaged disk. 

5. Make sure the new disk is of the same model as the other three. 

6. Check the master and slave settings of the disks. 

Disk checking after maintenance: 

1. Turn on the server. 

2. Make sure no disk error message is shown on the LCD panel. 

3. Login the system as administrator. 

4. Check the disk status in disk volume configuration page. If the message 

“Not initialized” is shown, the disk is installed successfully. 

5. When the disk volume is configured as RAID 1, the system will rebuild 

upon successful restart. Make sure the system works properly and no 

errors are displayed after rebuilding. 

Can I connect my PC's USB/eSATA port to NAS via USB or eSATA cable to access the DATA? 

No, the USB / eSATA port on the NAS can only be connected to peripheral 

device. You can only connect to the NAS through the Ethernet network. 

▲Back 

What is the definition of HDD SMART status, Abnormal, Normal & Good? 

Abnormal Normal Good 

1. Any SMART value is equal 

or less than threshold. 

2. Hard Disk temperature is 

higher than 65 degree C. 

▲Back 

1. Any Smart value is equal or less than threshold + (initial_SMART_value - threhold)/2. For 

example, if the initial SMART value is 100, the current value is 50, the threshold is 20, then 

the Smart value, 50, is less than 20+(100-20)/2. Thus, the health level would be Normal. 

2. Any SMART test (Rapid or Complete) result of last 20 times is abnormal. 

3. Hard Disk temperature is between 55 to 65 degree C. 

None of the conditions 

listed on the left side. 



VERSION: 2.1 

CELVIN ® NAS SERVER INSTALLATION & SETUP 

What happens if I press the reset button of the NAS? 

When you press the reset button on NAS, a beep sound will be heard. 

The following settings are reset to default: 

� System admin password: admin 

� Network Settings / TCP/IP Configuration: Obtain IP address settings automatically via DHCP 

� Network Settings / TCP/IP Configuration: Disable Jumbo Frame 

� Network Setting / System Port Management: 8080 

� System Tools / IP Filter: Allow all connections 

▲Back 

My NAS lost all its settings, and all HDDs are shown as unmounted. 

In case of corrupt/lost config: 

1. Power off the NAS and remove the HDD(s) 

2. Power on the NAS 

3. After a short beep and a long beep, plug the HDD back into the NAS 

4. Run Fujitsu Finder, it will find the NAS, do NOT configure it! 

5. Connect to the NAS by telnet port 13131 (e.g. with Putty) 

6. Run the following commands to recover with default configuration 

Use the following commands if using 1 drive: 

# mount /dev/sda1 /mnt 

# cd /mnt/.config/ 

# cp /etc/default_config/uLinux.conf /mnt/.config/ 

# reboot 

▲Back 

Use the following command if using 2 drives: 

# mdadm -A /dev/md9 /dev/sda1 /dev/sdb1 

# mount /dev/md9 /mnt 

# cd /mnt/.config/ 

# cp /etc/default_config/uLinux.conf /mnt/.config/ 

# reboot 

7. Above procedure will reset the configuration back to default and then you 

need to reconfigure it. But all the share should be available now. 

Please remember NOT to re-initialize the HDD. Since this will format your 

HDD and all your data will be lost. 

8. To be prepared next time this happens, always make sure you have a 

working backup of your personal uLinux.conf. 

Note: uLinux.conf is the main settings configuration 

Is there a newer firmware available for the NAS Device? Do I need to install that? 

Check the Fujitsu support page. If you see an available firmware you may need 

to download it and install it. Please verify first which version you have and then 

compare the release date. 

▲Back 

How to start the Fujitsu Finder to reinitialize the CELVIN® NAS Server? 

Please remove your hard drives. Boot up the NAS without HDD installed. 

The system will use the embedded image to boot up. Then run the Fujitsu 

Finder on your PC, it will help you to find the NAS on the network. 

▲Back 

To check which version you have, go to the WebUI of your NAS Device, 

the firmware version of your NAS is shown on bottom left. 

Use the default username and password to login. 

Hot-plug the HDD into the NAS, and go thru the installation process including 

formatting hard disk & install the firmware. 

The Fujitsu Finder / Quick Install Wizard cannot find the NAS Device during the discovery process. 

Windows XP SP1 with Internet Firewall enabled will not allow the Fujitsu Finder 

to find the NAS Device during the discovery process. The Internet Firewall 

must be momentarily disabled for the Quick Install Wizard to find the NAS 

Device properly. Once the Shortcut icons are created on the Desktop, the 

Internet Firewall settings can be re-enabled. 

▲Back 

In Windows XP SP2 the Internet Firewall does not need to be disabled. 

However, a popup message will appear when running the Quick Install Wizard. 

Agree to the popup message to continue with the detection process. 



VERSION: 2.1 

I have installed and followed all the instructions, but I cannot run the setup for the NAS Device. 

You may need to RESET the device and then run the Quick Install Wizard / 

Fujitsu Finder again. For the best result, make sure you wait until the NAS 

Device is fully booted. 

▲Back 

Do I lose all my data after I performed the system reset? 

The Reset function on "System Administration > System Reset" is designed to 

reset all settings of the NAS to default. 

When you press Reset on this page, all drive data, user accounts, network 

shares and system settings are cleared and restored to default. 

▲Back 

Initialization stops during first time installation. What can I do? 

If your NAS and PC are connected to the same router, enable DHCP on NAS 

and you should be able to access the server. To set a fixed IP for NAS, make 

sure the subnet mask, default gateway, and the DNS server settings of your 

NAS and PC are the same. 

▲Back 

Why is the disk size of the NAS reduced after RAID configuration is finished? 

When configuring two disks as RAID 1, the disk size usable is equal to the size 

of one disk. 

Hard disk manufacturer calculates disk size as 1M=1000K while computer 

calculates actual disk capacity as 1M=1024K. 

▲Back 

What's the limitation on the length of server name? 

The server name can be 14 characters long at maximum, which can contain 

alphabetic characters, numbers and hyphen (-). 

▲Back 

What's the limitation of the username and password setting? 

User name 

The user name must not exceed 32 characters. It is case-insensitive and can 

contain double-byte characters, such as Chinese, Japanese, and Korean 

except: " / \ [ ] : ; | = , + * ? < > ` ' 

▲Back 

Can I use Unicode character in password? 

No, for password, only English alphabets and numbers are supported. 

You can use Unicode characters for user name only. 

▲Back 

When you see that the POWER LED and the LAN LED are both ON, and not 

blinking, then the NAS Device has completed its boot up process. 

Please make sure you have backed up all the important data and system 

settings before resetting the NAS. 

If you connect the NAS directly or there is no DHCP server on the network, the 

NAS will use 169.254.100.100 as its IP address. Please configure your PC to 

the same IP subnet, for example, 169.254.100.101. 

When a manufacturer marks a disk size as 160G (disk size: 

160G=160,000M=160,000,000K), the actual usable disk capacity could be 

160,000,000,000K/1024/1024 = 152 G. 

The server does not accept names with space, period (.), or names in pure 

numbers. 

Password 

The password is case-sensitive and can be 16 characters long at maximum. It 

is recommended to use a password of at least 6 characters. 



VERSION: 2.1 

After firmware upgrade, why I cannot login to the web administration page with correct admin account? 

Please clear your browser cache and reconnect again. 

On Internet Explorer 8 or Mozilla Firefox you can press Ctrl+Shift+Del to clear 

the cache. 

▲Back 

If there's a hardware failure, can I put the HDDs in the replacement NAS and keep the data? 

Yes, simply move all the HDDs in the exact order to the replacement CELVIN® 

NAS Server (same model) when the NAS is powered off.

VERSION: 2.1 

HDD SPIN DOWN (HDD STANDBY) 

Why does the hard drive of the NAS not go to standby mode? 

First of all, make sure you have enabled the "disk standby mode" function in 

System Tools / Hardware Settings on the administration page. If the function 

does not work according to your settings, you may check if the following 

services are running. There must NOT be any access to these services for the 

HDD standby mode to work properly: 

� UPnP/Twonkymedia function on NAS 

� NTP server 

� BT download 

� Microsoft Networking -> AD service, WINS server, Domain Master 

� Share folder mapping 

Network access to the NAS. If the NAS is connecting to Internet, make sure 

you don’t enable DMZ or port forwarding on your router/firewall. Hacker may try 

to connect your NAS and thus prevent HDDs to entering standby. 

Fujitsu Finder, Quick Install Wizard, NetBak Replication, QGet. These 

programs will keep checking the existence of the NAS and prevent it to 

entering standby. 

▲Back 

Why does my HDD go to standby mode later than the time I have set? 

The hard drive(s) on CELVIN® NAS Server may seem to go to standby mode a 

bit later than the time you specified when data writing is in process. In fact, this 

is related to the data writing behavior of the embedded Linux system. When 

you save data to the NAS, the data is written to the system cache first and then 

▲Back 

If your NAS is shared among multiple PC on the same network, be sure there 

is no access from the PC to the NAS. You can disconnect the LAN cable to 

assure this. 

If you have installed add-on programs like Joomla or phpMyAdmin on your 

NAS, the HDD standby mode of CELVIN® NAS Server might not work since 

these programs might affect the service access status to the NAS. 

If you have copied a lot of pictures to the NAS, the NAS will create thumbnail 

files for the pictures. This may take a long time (even days if there is great 

number of pictures). You can see a running process “/usr/local/sbin/ImR_all - 

soft /Qmultimedia” after issue ps command via SSH. Please wait patiently for 

this process to complete. 

If you still have problem, please connect the NAS by ssh port 22 or telnet port 

13131 and issue ps command. This will show all the running procedures. 

to the hard drive(s) on the NAS. The write time depends on the size of the data. 

After the data is written and there is no access to the hard drive, the hard 

drive(s) go to standby mode according to your settings in System Tools / 

Hardware Settings on the administration page. 

Can the HDDs remain in spin-down to conserve energy when just accessing the admin page? 

Since the configuration and log files are stored on the HDD, any access or 

change to the NAS will wake up the NAS from standby mode.

VERSION: 2.1 

RAID 

I have e.g. 2*250GB drives in RAID 1. In case drive fails, is it possible that I remove one 250GB drive and replace it 

with a 500GB drives? 

Yes. However, the array capacity is based on the size of smaller drive. You 

could not have the 500GB RAID 1 until you back up the data to your PC or an 

external drive first, and then use 2*500GB drives for a new RAID 1 

▲Back 

What should be done when disk error is detected for RAID 1/5/6 configuration? 

Take out the failed drive and replace it with a proper one of the same model or 

same/bigger size. To replace the failed disk with a different volume one, make 

sure the new disk is larger in size than the old one for rebuilding RAID 

▲Back 

configuration. After the new RAID1 is configured, please copy the data back to 

your NAS 

configuration. However, only the size of the old drive will be used for the new 

one. Extra size of the new drive will not be used. 

I’m using RAID 1 with my CELVIN® NAS Server Q800, but the performance does not meet the expectations. 

In order to get best performance in RAID1 setup with CELVIN® NAS Server 

Q800, it is recommended to use HDD slot 1 and 3 or HDD slot 2 and 4 for 

installing the two hard drives. 

▲Back 

When using HDD slot 1 and 2 or HDD slot 3 and 4 for your RAID 1, there may 

be a write performance decrease of ~30%. 

If the internal disk of CELVIN® NAS Server Q600 fails or the mainboard is changed when Q-RAID1 configuration is 

enabled, can I replace the internal disk with an eSATA or USB disk? 

Yes. The internal disk can be replaced by the external disk. You can also install 

a new internal disk and execute “Restore” function to restore the data from the

The RAID migration / expansion speed is very slow, is this normal? 

The first half of the RAID migration / expansion will take much longer than the 

second half. The second 50% will take just a few hours to complete. Thus, the 

RAID migration / expansion should be completed about half of time than you 

estimate from the progress percentage. 

▲Back 

Our RAID migration / expansion is on-line. You can still use the NAS to 

read/write data as usual. 

Can I have two or more RAID volumes on my NAS? For example, RAID 1 for HDD slot 1&2, RAID 0 for HDD slot 

3&4. 

Yes, you can have two or more RAID volumes if the drive numbers support it. 

However, please refer to “I’m using RAID 1 with my CELVIN® NAS Server 

Q800 , but the performance does not meet the expectations.” to ensure the 

best possible read/write performance.

VERSION: 2.1 

I’ve already created two RAID 1 (or RAID 0) volumes. Can I create a RAID 0 (or RAID 1) over these two RAIDs? 

No, you can only create raid over hard disks (1-level). Creating RAID over 

another RAID (2-level) is not supported. That means RAID01 and RAID10 

are not supported on our NAS (yet).

PRINTER SERVER 

Why can’t I find the network printer? 

Please do not create a folder with a name identical to the printer name 

otherwise you will not find the printer. 

▲Back 

How do I change the name of the printer connected to the NAS? 

The printer name is named according to the name of NAS. To change the 

printer name, change the server name of the NAS and restart the server. 

▲Back 

The printer name will be changed but the end of the name will still be "pr" or 

"pr2" "pr3". For example, the name of NAS is “nas”, then the printer name will 

be naspr. 

When I configure a printer for a PC in AD domain an authorization warning message is shown. 

Please login as administrator or other users with administrator rights in AD. 

Or do not login AD and use the administrator access rights of the PC to 

configure printer first.

REMOTE REPLICATION / DISASTER RECOVERY 

Can I use remote replication to back up data to PC or NAS of different brands? 

You can back up the data to PC or NAS with standard Rsync server installed. 

▲Back 

How to synchronize all data between two NAS devices? 

Setup Remote Replication function, and enable "Perform incremental 

replication" function, "Delete extra files on remote destination" function. 

▲Back 

Why are files not completely backed up by the remote replication of the NAS? 

This may due to corruption of files or file name settings. If the files are not 

damaged, you can check the language settings of the source and destination 

NAS servers. Make sure their language settings are the same. CELVIN® NAS 

▲Back 

Server will skip backing up the files when errors are found and cannot be fixed 

during replication. 

Why does remote replication from NAS to external USB disk fails when the USB/eSATA disk is in FAT format? 

This is a limitation of FAT file system. Some special characters are not 

supported by FAT file system, including / ? \:*|" 

▲Back 

If the name of the source file contains any of these characters, remote 

replication will fail. 

I want to backup my data through the Internet. If I setup the NAS behind a firewall, and enable the Remote 

Replication function, which port I should open on the firewall rule? 

The port used is 873 by default and is configurable. 

▲Back 

What should be done to make CELVIN® NAS Server back up the folders on the server automatically via self 

remote replication? 

Set the remote server IP as 127.0.0.1 to make the NAS back up the data on 

itself. For example, there are two network shares A and B. 

▲Back 

To make CELVIN® NAS Server backup data on A to B automatically, set 

remote CELVIN® NAS Server IP as 127.0.0.1 and remote folder as B, the data 

will then be backed up from A to B. 

My company often schedules backup job in non-office hours, how can I check the backup result when out of 

office? 

You can check the status of NAS backup and restore jobs in office or at home 

by accessing web administration interface.

All current statistics and past records are recorded in Statistics and Logs 

section. 



VERSION: 2.1 

If the NAS device abnormally shutdown, the Remote Replication function will continue? 

If remote destination NAS power off, network failure or other abnormal situation 

happened, the Remote Replication function will stop, and it will start on the next 

schedule. 

▲Back 

I configured a weekly remote replication job but got an error. 

This error is caused by the case-sensitiveness of the folder name for remote 

replication. 

▲Back 

Note: Please enable "Perform incremental replication" function, and then 

system will backup new files only, or it will backup from the beginning. 

The remote host testing cannot identify the case of the folder name, e.g. Music 

and music. Please enter the correct folder name (case-sensitive) and try again. 

Why does remote replication not start after a long while when file compression option is enabled? 

When file compression option is selected for remote replication, files will be 

compressed first before backup. Therefore, more time will be taken before 

replication starts. 

▲Back 

Why can the remote server not be connected after clicking on the test button in remote replication? 

After pressing the test button, you have to enter the password again to use 

remote replication

FTP SERVER 

I use the NAS Device as a FTP server, but the users that are outside the LAN cannot access to it. 

To use the NAS Device as a FTP server without fixed IP or domain name, 

please setup your DynDNS (if IP is not fixed) and Port Mapping of router (IP 

Sharing) first. As for the setting, please refer to the DynDNS and Port mapping 

in your router’s Manual. 

▲Back 

We recommend to use a fixed IP address on the NAS Device and then 

configure your Router. Depending on the brand you use, you need to access 

the following: 

� Firewall > Virtual Servers 

� Virtual Server 

� Port Forwarding / Port Triggering 

� Advanced Routing 

I tried to access some files on NAS via FTP by Internet Explorer but the file names are displayed incorrectly and I 

could not access the files. Why? 

This is a limitation of Internet Explorer. When you access the files on an FTP 

server via IE, IE retrieves the information of the files, e.g. owner of the file, the 

user group that the owner belongs to, and last modified etc. 

Figure 1 

To view the files correctly, you can use FTP clients, like File Zilla, or Mozilla 

Firefox (Figure 2) to access the FTP site. You can also modify the user group 

name and delete the space characters in the name. 

Figure 2 

▲Back 

Why can't I see the correct filename using my FTP client? 

Your FTP client does not support Unicode. Set "No" for Unicode Support from 

[FTP Service] under [Networking Settings]. Select a supported filename 

encoding from [Language Setting] under [System Settings] so that the folders 

and files on FTP can be properly shown. 

▲Back 

However, when the there is a space in the user group name, e.g. Power Users, 

IE recognizes the first word as the user group name and the word after the 

space as the value for the next variable. Therefore, the file names are 

displayed incorrectly (Figure 1). 

If the user group belongs to your Windows server, you can go to Control Panel 

/ Administrative Tools / Computer Management to change the group name 

(Figure 3). Note that you must have the administrator rights to change the 

group name. 

Figure 3 

Or you can just use the proper FTP client which supports unicode, such as 

"SmartFTP", "FileZilla" or "FTPRush". 



VERSION: 2.1 

How to determine which language to be set for FTP? 

If you need to connect to CELVIN® NAS Server via FTP, please follow the 

steps below to configure the language setting: 

1. In “System Settings - Language Setting” page, select the language that 

most users use. 

2. If your FTP client does not support Unicode, e.g. Internet Explorer, 

CuteFTP, WSFTP or Command-Prompt FTP, go to Network Settings-FTP 

Service page and disable Unicode support. 

▲Back 

3. If your FTP client supports Unicode, e.g. FileZilla, enable Unicode support 

in the client. Then go to Network Settings-FTP Service page and enable 

Unicode support. Check if the files can be properly displayed in Internet 

Explorer. 

How can I setup the FTP server to allow FTP user can only upload files but cannot view / download files? 

Please log on web administration interface by admin. 

1. Go to [Share folders] under [Access right management] 

2. Click the property and you can enable [write-only access on FTP connection]

FILE SERVER & WEB FILE MANAGER 

What file systems does the NAS support for the external USB/eSATA device? 

The NAS supports the following File Systems: 

� ext3 

� ext4 

� FAT 

� NTFS 

� HFS+ (only with newest firmware) 

▲Back 

Why can’t I login to the CELVIN® NAS Server with correct user name and password when I connect via Windows 

explorer? 

This is a limitation of Windows. If you already logged in to CELVIN® NAS 

Server from the PC, you cannot login to it with another user name from the 

same PC unless you logout. To solve this problem, please run Command 

Prompt in Windows and input the command [net use]. 

▲Back 

Is it possible to configure access control for sub-folders? 

NAS supports access control for main folders only. 

▲Back 

Check if there is a connection to CELVIN® NAS Server. If yes, input the 

command [net use \\xx.xx.xx.xx\ss /d] (xx.xx.xx.xx = CELVIN® NAS Server IP 

address, ss=share name). 

Can users in different network domains configure the same NAS as network disk drive? 

Yes. To access NAS by computer name, make sure there is WINS server in 

your network and the service is enabled. If not, you can access the server via 

NAS IP. 

▲Back 

Why are all files tagged as hidden system files? 

You can fix this with the following procedure: 

1. Make sure that system files were shown. 

2. Copy all the folders, using a windows explorer, to the XP machine. You 

may want to do this to a folder directly in C: (for example "c:\iamlost"). 

3. Open a Command window --> (Start/run, and type "cmd", press enter) 

4. Cd to the directory where you copied the files to (example: cd c:\iamlost) 

5. Next we have to get rid of all the attributes; 

type "attrib -R -A -S -H /S /D" 

▲Back 

What you just did in step 5 is; you removed the file AND folder attributes -R 

(readonly), -A(archive), -S (system file,.. this is the one that's probably been 

bugging you), -H(hidden). The /S and /D are there to make sure you also 

process all sub-files and sub-folders. You should be able to make any changes 

to rights and visibilities again using the "normal" windows methods now. 

Why can the file name of a file with more than 33 characters not be displayed completely in the Internet Explorer 

browser? Is this a bug? 

No. The problem that a file name cannot be displayed in the IE browser 

completely is not related to the length of the file name. 

▲Back 

The file name is cut off because the display space of the IE status bar is limited 

and the total length of the path exceeds the buffer of the status bar. 



VERSION: 2.1 

How do I use anti-virus software to scan my NAS data? 

Please install anti-virus software on your PC and map the network share of 

NAS to the PC. Then scan the network share using the anti-virus software. 

You can use the following procedure to map network share: 

▲Back 

1. Execute Fujitsu Finder 

2. Apply [Map Network Drive] under [Tools] 

3. Choose the share you want to scan then map the drive 

When I use Photoshop 7 to save files to the NAS, why does it always show Disk Full? 

Photoshop 7 cannot correctly recognize disk space larger than 1TB. Please 

use the Quota function to restrict the available disk size for certain users to less 

than 1TB. 

▲Back 

Why can’t I log in with a user? I already gave the user RW or RO access right. 

(Why can I write into a share? I only gave the user RO access right.) 

The answers to the above two questions are the same; the access right priority. 

Deny > RW > RO > Empty (no setting). 

Example 1: 

“UserA” is a member of “UserGroup”. If you give “UserA” RW or RO access 

right to “Public” share folder and at the same time you give “UserGroup” Deny 

to “Public”, per the access rule above, resulting access right for “UserA” is 

Deny. 

Example 2: 

“UserB” is a member of “UserGroup”. If you give “UserB” RO access right to 

“Qmultimedia” share folder and at the same time you give “UserGroup” RW 

access right to “Qmultimedia” share folder, per the access rule above, resulting 

access right for “UserB” is RW.

How to allow Windows 98 to connect to CELVIN® NAS Server? 

1. Connect the NAS by ssh (port 22, enabled by default) or telnet (port 

13131, disabled by default) and add the following to Global section of 

smb.conf under /mnt/HDA_ROOT/.config by vi command. 

lanman auth = yes 

client lanman auth = yes 

2. Run the following command to restart samba: 

/etc/init.d/smb.sh restart 

▲Back 

The user will then login with the accounts that have less than 1TB available 

space and avoid this problem. 

Example 3: 

“UserC” is a member of “UserGroupA” and “UserGroupB”. For share folder 

“Qdownload” you give “UserGroupA” RW, “UserGroupB” RO, and you do not 

configure “UserC” (Empty), the resulting access right for “UserC” is RW. 

Note: All users are in group “everyone” by default, please check your 

“everyone” access right for conflicts. 

3. Enter the web administration page and select [User Management] -> 

[Users] -> select the users that will use Windows 98 to connect the NAS 

and click [Change Password]. 

4. Input the password for the Windows 98 users and click OK.

WINDOWS ACTIVE DIRECTORY SERVICE 

How do I access the user account and group data from AD Domain? 

It is suggested to use Windows 2000 Service Pack 4 or Windows 2003 Service 

Pack 1. 

Check your AD server settings: 

1. Make sure you have enabled Active Directory Service on the Windows 

server. If you have enabled AD, you can find the menu “Active Directory 

Users and Computers” on “Administrative Tools” of Windows. 

2. Reset the password of “administrator” account on AD server after creating 

“Active Directory” service on AD server. 

3. The DNS server settings on the AD server should have at least two 

records. For example, you have an AD server with IP address 

10.8.10.113, server name: celvinsbs.tsdsbs.local, domain name: 

tsdsbs.local 

DNS settings on AD server: 

a. “A record” for AD server itself: celvinsbs Host(A) 10.8.10.113 

b. “A record” for domain: (same as parent folder) Host(A) 10.8.10.113 

How to create “A record” for domain on DNS settings: 

i. On “dnsmgmt”, select New Host(A) in Action. 

ii. Enter IP address: 10.8.10.113 (AD server IP address), 

and then click “Add Host”. 

4. The DNS IP on “Network setting” of AD server should have a record of 

the AD server IP. 

Check the following items on NAS: 

a. DNS server setting on NAS should be directed to AD server. 

b. Check the “time zone” and “Current date and time” on NAS, AD 

server can synchronize only if their time difference is less than 5 

minutes. 

▲Back 

When adding NAS to AD, will the access authority of Windows be copied to NAS? 

No. Access authority set in Windows will not be copied to NAS. You should set 

the access right on NAS. 

▲Back 

5. You should use the full domain name in AD settings of NAS. For 

example, if your FQDN name of AD server is “celvinsbs.tsdsbs.local”, you 

should use “tsdsbs.local” as the domain name. 

Domain Username must be entered for AD domain. (We use 

“administrator” in this case). 

6. NAS and AD server will synchronize each 5 minutes. To configure the 

settings manually, NAS has to be set as standalone mode and then 

added to AD domain again. 

If you cannot join AD domain, please switch to “Standalone” setting. 

Check all the settings and join AD again. 

Notes: On joining AD 

1. After joining NAS to AD domain, you must login the share folder of NAS 

by “domain_name\Username”. NAS local user account cannot be used 

anymore on network sharing. 

For example: peter is an account on the AD domain (tsdsbs.local) 

2. AD can be joined successfully even if NAS and AD server are on different 

subnets. 

3. After NAS has joined AD domain, the authority of “everyone” will not 

work, “everyone” is the original account of NAS, but is not included in AD. 

Therefore the authority has to be reset. 

4. DNS settings on Windows 2000 server should be added as “Active 

Directory DNS”. 

5. If you change the DNS setting on the Windows server, please reboot the 

server to avoid DNS cache error. 

When adding CELVIN® NAS Server to Active Directory domain, will it inherit file read/write rights of Windows? 

No, CELVIN® NAS Server is not able to inherit the access right from Windows. 

The access right will remain the same per original setting on CELVIN® NAS 

Server.

My NAS crashed and I need to access my data urgently. When I connect the disk to my Windows PC, the file 

system format is unrecognizable. What can I do? 

If the volume is single or RAID 1 and the file system is formatted as ext3, you 

can install an ext3 driver (for example, explore2fs, ext2ifs and ext2fsd) on your 

Windows PC to access the data on the 3rd partition of the HDD. You can refer 

the following links to download the driver.

What should be done when disk access rate becomes very slow? 

1. Restart the server. 

2. Check the current disk settings and status. In case of hard disk failure, 

repair it ASAP. 

3. Check if other devices for network access have the same problem. If the 

internal network is not functioning properly, like certain PCs are infected, 

contact your technical support.

4. When there is mass access to disk data or replication is in process, disk 

access will become slower due to heavy workload of CELVIN® NAS 

Server. You may try to access to the NAS later. 

5. If you connect by wireless, try wired connection. 

I forgot my IP address setting, how can I find the IP address of the CELVIN® NAS Server? 

For Windows users, please use the Quick Install Wizard / Fujitsu Finder to find 

the IP address of the CELVIN® NAS Server. For Mac users, please use the 

Mac QFinder.

How to determine if two network devices are in the same LAN? 

Example 1: 

Assumed that there is a PC A with IP: 192.168.1.10 and subnet mask: 

255.255.255.0. PC A wants to connect to PC B with IP: 192.123.2.3. Multiply IP 

of PC A by the 4 digits of subnet mask A (convert 255 as 1). Then multiply the 

4 digits of PC B’s IP by the 4 digits of PC A’s subnet mask (convert 255 as 1). If 

the sum is the same, they are in the same LAN. If not, they aren’t. 

IP (PC A): 192.168.1.10

volumes is almost full. 

Log: The system event log has a new warning entry showing the specific 

volume that’s nearly full. 

(E.g. [Single Disk Volume 1] Disk Space is almost full.)

How does the CELVIN® NAS Server encrypt the built-in Hard-drives? How do I unlock them? 

The enhanced encryption technology uses AES-256 to encrypt disk volumes. 

The 8-16 character long, user-created passphrase and the generated key file 

via Web UI will create the encrypted disk volume based on the Linux LUKS 

mechanism. When the NAS reboots each time and before data can be

If I add a Virtual Disk to my NAS, can the volume capacity be merged to this volume? 

No. The Virtual Disk will show in another volume with the name VirtualDisk1

accessed, the encrypted disk volume must be mounted via the input of the 

passphrase or the key file on the Web Management UI. On the other hand, 

users can also choose to store the key file in the NAS for automatic unlock 

upon each reboot, without the manual input each time. 

When I save the connection log to a csv file and open the csv file, the connection type and action are number 

coded. How do I know the meaning of the number? 

Here are the connection type codes: 

0 - UNKNOWN 

1 - SAMBA

3 - HTTP 

4 - NFS 

5 - AFP 

6 - TELNET 

7 - SSH

Why does WinRAR show file names as unrecognized characters and fail to decompress after compressing the 

files with Web File Manager? 

This is because Web File Manager uses UTF-8 encoding for compression. 

WinRAR v3.92 and earlier versions cannot fully support UTF-8 encoded files. 

Please use WinZip as an alternative solution for decompression.
