User Service Guide, Third Edition - HP Integrity cx2620 Server

Determining the iLO MP LAN Configuration Method
To access the iLO MP through the iLO MP LAN, the iLO MP must acquire an IP address. The
way the iLO MP acquires an IP address is dependent upon whether DHCP is enabled or disabled
on the server, and if DHCP and DNS services are available to the server. (See Table 3-6 for possible
scenarios.)
Once you have determined the iLO MP access, you must determine how you will configure the
iLO MP LAN in order to acquire an IP address using the following methods:
• DHCP/DNS
• ARP Ping
• Local S-232 serial console port
• Remote/modem port
Table 3-6 provides all the possible scenarios to consider. Use this table to help you select the
appropriate LAN configuration method to obtain an IP address.

Once you have determined how you will configure the iLO MP LAN in order to acquire an IP
address, you must configure the iLO MP LAN using the selected method.
Configuring the iLO MP LAN Using DHCP and DNS
DHCP automatically configures all DHCP-enabled servers with IP addresses, subnet masks, and
gateway addresses. All HP Integrity entry class servers with the iLO MP are shipped from the
factory with DHCP enabled.
HP recommends using the DHCP and DNS method to simplify access to the iLO MP.
When you use DHCP and DNS, you can connect to the iLO MP by typing the default host name
in your browser rather than an IP address only if the following applies:
• DHCP must be enabled (DHCP is enabled by default).
• You are using a DHCP server that provides the domain name and the primary DNS server
IP address.
• The primary DNS server accepts dynamic DNS (DDNS) updates.
• The primary DNS server IP address has been configured through the DHCP server.
IMPORTANT: You must know the DNS domain name, which is served out by the DHCP server,
unless its domain is local or the same domain.
To configure the iLO MP using DHCP and DNS, follow these steps:
