Once you have determined the iLO 2 MP access, you must determine how you will configure the
iLO 2 MP LAN in order to acquire an IP address. There are three methods available.
• DHCP/DNS
• ARP Ping
• RS-232 serial port
Table 13 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 2 MP LAN in order to acquire an IP
address, you must configure the iLO 2 MP LAN using the selected method.
Configuring the iLO 2 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 iLO 2 are shipped from the factory
with DHCP enabled.
HP recommends using the DHCP and DNS method to simplify access to iLO 2.
NOTE: You can use ARP Ping regardless of the status of DHCP unless an IP address has ever
been acquired using DHCP. Once an IP address is assigned using DHCP, ARP Ping is permanently
disabled.
When you use DHCP and DNS, you can connect to iLO 2 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.
• 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 it’s domain is local or the same domain.
To configure the iLO 2 MP using DHCP and DNS, follow these steps:
