• 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 was configured through the DHCP server. To configure the iLO MP using DHCP and DNS, follow these steps: 1. Obtain the factory-set DNS name from the toe-tag on the server. The DNS name is 14 characters long. It consists of the letters MP followed by the 12 characters of the MAC address. For example, mp0014c29c064f This address is assigned to the iLO MP core I/O board. The core I/O board has a unique MAC address that identifies the hardware on the network. 2. Connect the LAN cable from the server to an active network port. 3. Apply ac power to the server. 4. Open a browser, telnet, or SSH client and enter the DNS name. The iLO MP Log In screen appears. 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 36). 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 negates the DHCP over 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 is assigned using the LC command or ARP Ping succeeds. Select one of the following methods: 1. Connect a PC to the network that is on the same physical subnet as the server and run the ARP Ping commands from the PC. 2. Locate an existing server on the network, log into it, and run the ARP Ping commands from the server. Table 3-4 lists the ARP Ping commands. Configuring the iLO MP LAN Using ARP Ping 33

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 was configured through the DHCP server.
To configure the iLO MP using DHCP and DNS, follow these steps:
1.
Obtain the factory-set DNS name from the toe-tag on the server. The DNS name is 14
characters long. It consists of the letters
MP
followed by the 12 characters of the MAC address.
For example,
mp0014c29c064f
This address is assigned to the iLO MP core I/O board. The core I/O board has a unique
MAC address that identifies the hardware on the network.
2.
Connect the LAN cable from the server to an active network port.
3.
Apply ac power to the server.
4.
Open a browser, telnet, or SSH client and enter the DNS name. The iLO MP Log In screen
appears.
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 36)

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 negates the DHCP over 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 is assigned
using the
LC
command or ARP Ping succeeds.
Select one of the following methods:
1.
Connect a PC to the network that is on the same physical subnet as the server and run the
ARP Ping commands from the PC.
2.
Locate an existing server on the network, log into it, and run the ARP Ping commands from
the server.
Table 3-4
lists the ARP Ping commands.
