Network Connection Overview; Connect To The Network - HP Integrated Lights-Out User Manual

iLO firmware detects the presence of RILOE II and automatically disables iLO functionality. Additionally, if
iLO firmware detects the presence of the original RILOE, and iLO displays an invalid configuration
message.
To re-enable iLO functionality after a RILOE II is removed, use the Security Override Switch and iLO RBSU
(on page 14). Select Settings>Enabled for the Enable Lights-Out functionality setting.

Network connection overview

There are three general network connection scenarios. iLO can be connected on:
A corporate network with both ports connected to the corporate network. In this configuration, the
server has two network ports (one server NIC, and one iLO NIC) connected to a corporate network.
This connection enables access to iLO from anywhere on the network. On a corporate network,
however, network traffic can hinder iLO performance.
A corporate network configuration reduces the amount of networking hardware and infrastructure
required to support iLO because iLO uses existing DNS and DHCP servers and routers.
A dedicated management network with the iLO port on a separate network. A separate network
improves performance and security, and provides redundant access to the server when a hardware
failure occurs on the corporate network. In this configuration, iLO cannot be accessed directly from
the corporate network.
A separate network increases the security of the management network because you can physically
control which workstations are connected to the network.
An iLO Shared Network Port using the server's NIC instead of the dedicated iLO management NIC
for server management. This configuration simplifies the network and reduces total network cost.
Fewer cables, hubs, and switches are needed because both regular and iLO network traffic comes
through the system NIC.
The main disadvantage of using the iLO Shared Network Port for iLO server management is the lack
of speed compared to the dedicated iLO management NIC. As a result, not all iLO management
features are available through the iLO Shared Network Port configuration.

Connect to the network

Typically iLO is connected to the network in one of two ways. iLO can be connected through a:
