Installation Guide, Second Edition - HP Integrity cx2620

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 it’s domain is local or the same domain.
To configure the iLO MP using DHCP and DNS, follow these steps:
1. Obtain the factory-set host name from the iLO MP Media Access Protocol (MAC) address
label on the server. The default host name is 14 characters long, consisting of the letters mp
followed by the 12 characters of the MAC address (example: mp0014c29c064f). This address
is assigned to the MP card. The MP card has a unique MAC address that identifies the
hardware on the network.
IMPORTANT: Make sure you obtain the MAC address to the MP card and not the MAC
address to the server core LAN card.
2. Connect the LAN cable from the server to an active network port.
3. Apply dc power to the server.
4. Open a browser, telnet, or SSH client and enter the default host name. The default host name
is the letters mp followed by the 12 characters of the MAC address. The iLO MP Log In
window opens.
5. Log in using the default user name and password.
CAUTION: When DHCP is enabled, the system is vulnerable to security risks because anyone
can access the iLO MP until you change the default user name and password.
HP strongly recommends you assign user groups and rights before proceeding. See “Modifying
User Accounts and Default Password” (page 57).
Configuring the iLO MP LAN Using ARP Ping
The Address Resolution Protocol (ARP) and Packet Internet Grouper (Ping) utility uses ARP
packets to ping, or discover, a device on the local network segment. The IP address you assign
to the server must use the same network segment, or subnet, as the computer assigning the
address. ARP does not work across routed or switched networks.
ARP Ping operational issues:
• You can use ARP Ping regardless of the status of DHCP unless an IP address has ever been
acquired using DHCP.
• When ARP Ping is successful, DHCP status is disabled.
• Some DHCP server options can cause the apparent issuance of ARP Ping to the iLO MP
which will negate the DHCP/DDNS method.
• The PC and the server must be on the same physical subnet.
• When a new server is first booted, DHCP is automatically available (factory-set default);
but ARP Ping does not start for three minutes after the iLO MP is booted. This applies to
every subsequent boot of the iLO MP until an IP address is obtained by DHCP or has been
assigned by using the LC command or ARP Ping succeeds.
There are two methods to use the ARP Ping utility:
