3.3 DHCPDHCP, Dynamic Host Configuration Protocol enables individual computers or devices toextract their IP configurations from a server (DHCP server). If the DHCP is enabled onyour iServer, as soon as the iServer is connected to the network, there is an exchange ofinformation between DHCP server and the iServer. During this process the IP address,the Gateway address, and the Subnet Mask will be assigned to the iServer by the DHCPserver. Note that the DHCP server must be configured correctly to do such assignment.If fixed or static IP address is desired, the DHCP must be disabled.The iServer is shipped with DHCP disabled (factory default). TheDHCP can be enabled by setting the DIP switch # 3 to the “ON”position (refer to Figure 3.2).DIP switch # 3 shownin “ON” positionONOFF4321ONOFF43213.4 DNSFigure 3.2 DIP Switch on the Bottom Side of iServerDNS, Domain Name System enables individual computers and devices to be recognizedover a network based on a specific name instead of an IP address. For example, insteadof having to use http://128.100.101.254 (IP address), you would use only http://eis03ecor any eight character name stored as Host Name under Access Control menu in theiServer Home Page. The default DNS name for an iServer is "eis" followed by the lastfour digits of the MAC address of that particular iServer.1. It is very important to communicate with the network administrator in order tounderstand the DHCP and its existing configurations on the host server,before enabling the DHCP on the iServer.2. The iServers are shipped with a default static IP address of128.100.101.254 and Subnet Mask of 255.255.0.0.3. On Novell networks or Windows 2000 where the DCHP is an updatedfunction of DNS this feature may be beneficial since a particular name can beassigned eliminating the need for the IP address, as described in Section 3.4.10
