The firmware supports HP-UX 11i version 2, June 2006 release, Linux®, Windows®, and OpenVMS
8.3 operating systems through the Itanium processor family standards and extensions, and has no
operating system-specific functionality included. All operating systems are presented with the same
interface to system firmware, and all features are available to the operating system.
User Interface
The Itanium processor family firmware employs a user interface defined by an HP standard called
Pre-OS System Startup Environment (POSSE). The POSSE shell is based on the EFI standard shell.
Several commands were added to the standard EFI Shell to support HP value-added functionality.
Event IDs for Errors and Events
The system firmware generates event IDs for errors, events, and forward progress to the iLO 2 MP
through common shared memory. The iLO 2 MP interprets and stores event IDs. Reviewing these
events helps you diagnose and troubleshoot problems with the server.
Controls, Ports, and LEDs
This section provides a basic description of the controls, ports, and LEDs found on the front panel
and rear panel of the server. For more information on LED functions and descriptions, see
