minutes, you are disconnected. You can increase the timeout using the telnetcfg command. For example, the following command increases the inactivity timeout to 10 minutes (600 seconds): telnetcfg -t 600 -T system:mm[1] Setting CRLF Over the years, there have been many variations on the interpretation of the Enter key in a Telnet session. Some Telnet daemons expect carriage return + linefeed (CRLF) and some expect carriage return alone (CR). From our testing, CR seems to be the most compatible. During your SoL session, if when you press the Enter key, the key behaves as though it was pressed twice and not once, then correct the CRLF option. Under Windows 2000 Telnet, do this as shown in Figure 5-15 before you open a connection to the Management Module. Microsoft (R) Windows 2000 (TM) Version 5.00 (Build 2195) Welcome to Microsoft Telnet Client Telnet Client Build 5.00.99206.1 Escape Character is 'CTRL+]' Microsoft Telnet> unset crlf Microsoft Telnet> open bcmm Figure 5-15 Setting CRLF in Windows 2000 Telnet Refer to the developer of your client for other Telnet implementations. 5.5.3 Open Firmware interfaces In some situations, you may need to access the Open Firmware interfaces to the BladeCenter JS20 firmware. This section explains how to access Open Firmware interfaces and how to use some of the functions they provide. Activating the Open Firmware interfaces You can access the Open Firmware interface whenever you power on a BladeCenter JS20. Before you can access the Open Firmware interface, set up the SoL remote text console function as described in 5.5, “Providing a console for the JS20 blades” on page 87. Use the following procedure to access the Open Firmware interface: 1. Using a Telnet or SSH client, connect to the Management Module external Ethernet interface IP address. 94 The IBM Eserver BladeCenter JS20
2. When prompted, enter a valid user ID and password. The default Management Module user ID is USERID, and the default password is PASSW0RD, where the 0 in the default password is a zero. Consider changing the defaults in any production environment. 3. Power cycle the blade and start an SoL console by using the power -cycle -c command. For example, to power cycle and start a SoL remote text console with the blade server in the first bay (bay 1), use the command: power -cycle -c -T system:blade[1] 4. After approximately 30 seconds, you see a sequence of checkpoint codes displayed on the console. These codes are generated by the Power On Self Test (POST). The meaning of the checkpoint codes is documented in the IBM Eserver BladeCenter JS20 Type 8842 Installation and User’s Guide. 5. Wait until the checkpoint code D5BB is displayed and then type 8. The POST pauses for approximately five seconds at this checkpoint code to give you time to respond to the checkpoint code. A number is displayed after the D5BB checkpoint code, indicating how many seconds remain before the POST will proceed further. For example, Figure 5-16 shows that four seconds remain.
