2 Setting up iLO
Preparing to set up iLO
Before setting up an iLO management processor, you must decide how to handle networking
and security. The following questions can help you configure iLO:
1. How should iLO connect to the network?
2. Will NIC Teaming be used with the Shared Network Port configuration?
3. How will iLO acquire an IP address?
4. What access security is required, and what user accounts and privileges are needed?
5. What tools will you use to configure iLO?
iLO network connection options
Typically, iLO is connected to the network through a dedicated management network or a shared
connection on the production network.
Dedicated management network
In this configuration, the iLO port is on a separate network. A separate network improves
performance and security because you can physically control which workstations are connected
to the network. A separate network also provides redundant access to the server when a hardware
failure occurs on the production network. In this configuration, iLO cannot be accessed directly
from the production network. The Dedicated management network is the preferred iLO network
configuration.

Production network
In this configuration, both the NIC and the iLO port are connected to the production network. In
iLO, this type of connection is called the Shared Network Port configuration. Certain Hewlett
Packard Enterprise embedded NICs and add-on cards provide this capability. This connection
enables access to iLO from anywhere on the network and reduces the amount of networking
hardware and infrastructure required to support iLO.
There are some drawbacks to using this configuration.
• With a shared network connection, traffic can hinder iLO performance.
• During the server boot process and when the OS NIC drivers are loading and unloading,
there are brief periods of time (2–8 seconds) when iLO cannot be reached from the network.
After these short periods, iLO communication is restored and iLO will respond to network
traffic.
