Usage Model

The common usage model for iLO is a client PC running a supported browser
using DHCP and DNS protocols connected to one or more iLO devices. To use
iLO, plug in the power of the host server and connect an Ethernet cable to the
dedicated iLO management port of the server. You can then use your Web
browser to connect to iLO over an SSL connection. When logged in, you can
remotely control the server from your client desktop.
Graphical Remote Console (on page 52), Virtual Media (on page 64), Terminal
Services Pass-through Option (on page 109), and Directory Services (on page
143) are advanced functions that must be enabled by licensing the optional iLO
Advanced Pack.
Linux customers might prefer connecting to iLO using the SSH interface instead
of a browser.

Network Connection Overview

There are three general network connection scenarios. iLO can be connected on:
GET_VM_STATUS (on page 328)
SET_VM_STATUS (on page 329)
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 coroporate 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.
