3.3 DHCP
DHCP, Dynamic Host Configuration Protocol enables individual computers or devices to extract their IP configurations from a server (DHCP server). If the DHCP is enabled on your iSE, as soon as the iSE is connected to the network, there is an exchange of information between DHCP server and the iSE. During this process the IP address, the Gateway address, and the Subnet Mask will be assigned to the iSE by the DHCP server. 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 iSE is shipped with DHCP disabled (factory default). The DHCP can be enabled by setting the DIP switch # 3 to the “ON” position (refer to Figure 3.2).

DNS, Domain Name System enables individual computers and devices to be recognized | |
over a network based on a specific name instead of an IP address. For example, instead | |
of having to use http://192.168.1.200 (IP address), you would use only http://eis03ec or | |
any eight character name stored as Host Name under the Access Control page in the | |
iSE Home Page. The default DNS name for an iSE is "eis" followed by the last four | |
digits of the MAC address of that particular iSE. | |
1. It is very important to communicate with the network administrator in order to | |
| understand the DHCP and its existing configurations on the host server, |
| before enabling the DHCP on the iSE. |
2. The iSE is shipped with a default static IP address of | |
| 192.168.1.200 and Subnet Mask of 255.255.255.0. |
3. On Novell networks or Windows 2000 Server where the DCHP is an updated | |
| function of DNS, this feature may be beneficial since a particular name can |
| be assigned eliminating the need for the IP address, as described in |
| Section 3.4. |
3.5 IP Address | |
Every active device connected to the TCP/IP network must have a unique IP address. | |
This IP address is used to build a connection to the iSE. Every computer using TCP/IP | |
should have a unique | |
the host ID. For instance, every computer on the same network uses the same network | |
ID. At the same time, all of them have a different host ID. For more details about the IP | |
address see Appendix B. |
