User Service Guide, Third Edition - HP Integrity cx2620 Server

Power
The server has two hot-swappable DC input power supply units. The power supplies have two
cooling fans and are designed for NEBS temperatures. The power supply plugs directly into the
power distribution printed circuit assembly (PCA), called PSI PCA.
Front Display Panel, DVD, and Diagnostic Panel
The LED status display is in the front of the unit directly above the DVD drive. The slimline DVD
drive is also in the front of the unit. It is center-mounted in the unit below the LED status display.
Mass Storage
The server has three hot-pluggable disk drives located in the front of the unit.
Firmware
Firmware consists of many individually linked binary images that are bound together by a single
framework at run time. Internally, the firmware employs a software database called a device
tree to represent the structure of the hardware platform and to provide a means of associating
software elements with hardware functionality.
The firmware incorporates Extensible Firmware Interface (EFI) which provides an interface
between the operating system and the platform firmware. EFI uses data tables that contain
platform-related information, and boot and run-time service calls that are available to the operating
system and its loader to provide a standard environment for booting.
The firmware supports the HP-UX 11i version 2 and Linux® 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 called Pre-OS System Startup
Environment (POSSE). The POSSE Shell is based on the standard EFI Shell. Several commands
were added to the standard EFI Shell to support HP value-added functionality. For more
information see the EFI and EFI/POSSE Commands at http://h20000.www2.hp.com/bizsupport/
TechSupport/Home.jsp.
Event IDs for Errors and Events
The server firmware generates event IDs similar to chassis codes for errors, events, and forward
progress to the Integrated Light-Out Management Processor (iLO MP) through common shared
memory. The iLO MP interprets and stores event IDs. Reviewing these events helps you diagnose
and troubleshoot problems with the server.
Preventative Maintenance
The server has an optional air filter assembly that installs over the front grill. The air filter assembly
consists of a frame and a separate foam filter element. The air filter assembly is used to filter the
air to minimize the amount of dust drawn into the server.
Replacing the foam filter element is performed by the customer as a preventative maintenance
measure. When the air filter assembly is installed on a server that is in a typical data center
environment (for data center environment information, see the HP Integrity cx2620 Site Preparation
Guide), HP recommends inspecting the foam element every two months and replacing it if
necessary. At a minimum, HP recommends that the foam filter element should be replaced no
less than every six months.
