1 Introduction to iLO 2

The Integrated Lights-Out Management Processor (iLO MP) for Integrity servers is an autonomous
management subsystem embedded directly on the server. It is the foundation of the server's
High Availability (HA) embedded server and fault management. It also provides system
administrators secure remote management capabilities regardless of server status or location.
iLO is available whenever the system is connected to a power source, even if the server main
power switch is in the off position.
HP has used several different names to describe the management functionality embedded in
servers, including "the management processor." In addition, HP uses the term "management
processor" to refer to any embedded microprocessor that manages a system. Management
processor is a descriptive term (such as "server"), and iLO is a brand name or label (such as
"Integrity").
Remote access is the key to maximizing efficiency of administration and troubleshooting for
enterprise servers. Integrity servers are designed so all administrative functions that can be
performed locally, can also be performed remotely. iLO enables remote access to the operating
system console, control over the server's power and hardware reset functionality, and works
with the server to enable remote network booting through a variety of methods.
The iLO 2 is an Integrated Lights-Out 2 management processor with the latest advanced digital
video redirection technology. This new feature gives you a higher performance graphics console
redirection experience than with the previous iLO.
This documentation addresses HP Integrated Lights-Out 2 (iLO 2) for Integrity servers and server
blades. For information on iLO for ProLiant servers and ProLiant BladeSystem server blades,
see www.hp.com/go/iLO.
NOTE: Previously, this document used the name iLO 2 MP as a reference to a management
processor. For the remainder of this document, we will simply refer to it as iLO 2 unless when
referring to physical components such as MP ports, connectors, LEDs, and so on.
IMPORTANT:
These details are frequently updated. For the latest server-specific product information, see the
Integrity iLO 2 Quick Specs on the HP website at www.hp.com/go/integrityilo.

Features

Integrity iLO 2 functionality includes the following:
• Monitoring of server health and status
• Control of power, reset, and Transfer of Control (TOC) capabilities
• Console access
• Display and recording of system events
• Display of detailed information about the various internal subsystems and field replaceable
units (FRUs)
• A virtual front panel to monitor system status and see the state of front panel LEDs
Integrity iLO 2 is completely independent of the host system and the operating system. It has its
own microprocessor and runs its own firmware. The operating system cannot send packets out
on the MP LAN, and packets on the MP LAN cannot go to the operating system. The MP LAN
is exclusive to iLO 2 and is driven by an embedded realtime operating system (RTOS) running
on iLO 2.
This guide addresses server-specific details that vary between server products.
