HP Integrity iLO 2 Operations Guide

1. Determine the physical access method to connect cables. There are two physical connections
to iLO 2 :
• Console serial port (RS-232)
• MP LAN port
2. Assign an IP address to the iLO 2 MP LAN using one of the following methods:
• DHCP and DDNS. Though there are several methods to configuring the LAN, HP
recommends DHCP with DNS. DHCP with DNS comes preconfigured with default factory
settings, including a default user account and password. Use the DNS name on the iLO
Network Information Tag on the server.
To assign a static IP address instead of using DHCP, use one of the following methods:
• ARP Ping. This method can be used for Integrity entry class only.
• Console serial port (RS-232)
Preparing to Set Up iLO 2
Perform the following tasks before you configure the iLO 2 MP LAN:
• Determine the physical access method to select and connect cables.
• Determine the iLO 2 MP LAN configuration method and assign an IP address if necessary.
NOTE: Server blade iLO 2s are assigned an IP address by the blade chassis OA.
Determining the Physical iLO 2 Access Method
Before you can access iLO 2, you must determine the correct physical connection method.
There are several ways you can physically connect to iLO 2. Table 9 lists the appropriate connection
method, required connection components, and connectors to the host console.
Table 9 Physical Connection Matrix
Required Connection ComponentsConnection Method
Console serial port
(RS-232)
• Host console
• Console serial port (RS-232) DB-9F to DB-9F cable (modem eliminator cable)
• Emulation terminal device (for example, a PC, laptop, or ASCII terminal)
These connection methods directly attach to the iLO 2 MP through the console serial port. This
is an RS-232 connection from a workstation to the server's iLO 2 MP console serial port. Serial
cable concentrators are used to provide switched access from one workstation to multiple
servers. Typically, the console serial port method is used by an administrator in the data center.
10/100 LAN cableLAN port
Remote access to the iLO 2 is a more convenient method. This remote access is through the
MP LAN port. Depending on your LAN administration, this can be restricted to the datacenter,
or extended outside the data center to your company's intranet.
For greater security, HP recommends restricting LAN access to well known, trusted and secured
networks.
The iLO 2 has a separate LAN port from the system LAN port. It requires a separate LAN drop,
IP address, and networking information from that of the operating system LAN port. See Figure 3
and Figure 4 (page 28) and use Table 9 to determine your physical connection method.
Determining the iLO 2 MP LAN Configuration Method
To access iLO 2 through the MP LAN, iLO 2 must acquire an IP address. The way iLO 2 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 10).
