Hard drives
The server has two HDD bays that support both non-hot-plug SATA hard drives and hot-plug SATA or SAS hard
drives. You can add a hard drive to an empty HDD bay by installing an appropriate drive option; servers
configured as non-hot-plug systems cannot use hot-plug hard drives, and servers configured as hot-plug systems
cannot use non-hot-plug hard drives.
The non-hot-plug SATA drive options include only the hard drive. Install these drive options using the HDD
carriers and mounting screws included with a server configured for non-hot-plug drives.
The hot-plug SATA and SAS drive options are pre-installed in hot-plug HDD carriers. Use these hot-plug drive
assemblies to replace any installed hardware in an HDD bay of a server configured for hot-plug drives. A hotplug HDD bay may contain a blank drive carrier or a hot-plug drive assembly.
Go to the HP website at http://www.hp.com/ and refer to the options list for this server model for the latest
information on supported hard drives.
Hard drive installation guidelines
Observe the following important guidelines when installing hard drives:
•Install only hard drive models specified for your ProLiant server. Installing unsupported hard drives may
damage the system by consuming power and generating heat in excess of the operating tolerance of the
server. This condition may result in a loss of system and/or data integrity.
•Install non-hot-plug SATA hard drives in the HDD carriers included with the server. Use four of the six HDD
screws pre-installed in each of the two HDD carriers.

Processor installation guidelines
Observe the following important guidelines before performing any of the installation steps listed in the next
section:
•The processor 1 socket (U42) must always be populated. If no processor is installed in this socket, the
system fails to boot, halts during POST, and does not function properly.
• Handle the processor and heat sink with care. Damage to either may affect processor performance.
• The processor socket pins are very fragile. Do not bend or damage them.
• Be sure that the server has the most recent ROM version. If the ROM is not the most recent version, failure to
flash the ROM before installing a processor can cause a system failure.
•HP does not recommend using a processor in the processor 2 socket (U55) when all processor 2 socket
DIMM slots (DIMM5 to DIMM8) are empty. Populate at least the DIMM7 and DIMM8 slots when you install
a second processor.
CAUTION: To prevent the heat sink from tilting to one side during installation or removal procedures, HP
recommends that you alternate tightening or loosening each screw a little at a time. Do not tighten or
loosen one screw completely before tightening or loosening the other.
CAUTION: To help avoid damage to the processor and system board, do not install the processor without
using the processor installation tool.
NOTE: The heat sink may differ slightly in appearance from the design shown in this document. This does not
affect the installation or removal procedures.
Removal and replacement procedures 33
Page 34

8. If the heat sink is new, remove the protective cover on the bottom of the heat sink.
9. Install the heat sink:
a. Align the heat sink over the processor, then place the heat sink on top of the processor and the heat
sink guide rails.
CAUTION: Do not overtighten the two spring-loaded screws or they may break off. A maximum
torque of 8-in-lb is set for the system.
b. Tighten the two spring-loaded screws a few threads, alternating between each screw. Then tighten the
screws completely to secure the heat sink to the processor base.
To tighten the screws, HP recommends using the L-shaped wrench that ships with the server.
IMPORTANT: If the heat sink is removed for any reason, it is critical that you apply more thermal
interface material to the integrated heat spreader on the processor to ensure proper thermal bonding
between the processor and the heat sink. Clean the contact surface of both the processor and heat
sink with an alcohol pad, then re-apply an HP-approved thermal interface material before re-installing
the processor. Use a pattern of five dots when applying the thermal interface material—one dot in the
center, and one dot at each corner. HP recommends using Shin-Etsu X23-7783D thermal grease
compound for your ProLiant server.

Memory installation guidelines
Observe the following important guidelines when installing memory modules:
•Use only HP-supported PC2-5300 DDR2 (667 MHz) registered ECC DIMMs in 512 MB, 1 GB, or 2 GB
capacities.
•The processor 2 socket (U55) must be populated before you can install memory modules in the DIMM5 to
DIMM8 slots.
•If a second processor is installed, HP does not recommend leaving all processor 2 socket DIMM slots
(DIMM5 to DIMM8) empty. Populate at least the DIMM7 and DIMM8 slots when the server uses a second
processor.
• Memory modules must be installed in pairs of the same size in the sequence listed below:
• For the processor 1 socket DIMM slots: Populate DIMM3 and DIMM4 first, then DIMM1 and DIMM2.
• For the processor 2 socket DIMM slots: Populate DIMM7 and DIMM8 first, then DIMM5 and DIMM6.
• Memory modules in DIMM1 and DIMM2 should not be larger in capacity than the modules in DIMM3 and
DIMM4; similarly, the modules in DIMM5 and DIMM6 should not be larger than the modules in DIMM7
and DIMM8.
Installing a memory module
1. Perform the pre-installation procedures described on page 11.
2. If necessary, remove any accessory boards or cables that prevent access to the DIMM slots.
3. Locate an empty DIMM slot on the system board.

Riser board assemblies
The server supports up to two expansion boards installed on riser boards. With the appropriate riser boards, the
two riser board assemblies that come with the server convert the expansion slots on the system board to slots that
are positioned at a 90° angle from the system board. You can then install expansion boards in a position
parallel to the system board.
The system comes with one full-sized assembly and one low-profile assembly. The full-sized assembly supports
either an HTX riser board or a PCI Express x16 riser board. The low-profile assembly supports either a PCI
Express x4 riser board or a PCI-X riser board.
NOTE: Some full-size expansion boards may not be supported due to a small blockage caused by the molded
connector on the end of the AC power cable. The connector molding reduces the overall component space
near the end of full-size expansion boards.

The system board contains the rear UID button (SW1) and the NMI button (SW3). Both are accessible from the
rear panel; the NMI button is recessed. Figure 73 on page 62 shows the locations of both buttons on the rear
panel; Figure 74 on page 63 shows the locations on the system board.
The front panel board contains the front UID button, which is accessible from the front panel. Figure 72 on page
62 shows the location of the UID button on the front panel; Figure 75 on page 66 shows the locations on the
front panel board.

UID button
When performing maintenance on multiple servers in a rack or similar configuration, you can use the UID buttons
on the front and rear panels to mark a server by changing the state of the blue UID LEDs. Push either UID button
to toggle both UID LEDs on and off.
NMI button
If the system crashes or stops operating properly, you can use the NMI button (SW3) to mechanically force the
server to issue a non-maskable interrupt. This performs a memory dump—writing the contents of the processor
registers and RAM to a network server or to diskettes. This memory dump can later be analyzed to determine the
cause of the problem.
The NMI button is a recessed button on the rear panel that is accessible with a small tool without removing the
chassis cover.
NOTE: Use of the NMI button is not supported in all network operating systems (NOS). Currently, the NMI
feature is not available for systems running on Solaris and Linux operating systems.
System jumpers
The system board has two jumpers — the crisis recovery jumper (P56) and the CMOS jumper (P57). Figure 74
on page 63 shows the locations on the system board. The following tables show the jumper settings.

Front panel board USB cable • J13 on the system board
CAUTION: Route the front panel board cables neatly. If necessary, secure them using the pre-installed cable
clips located on the chassis base. The cables should be routed in a position where they will not be pinched or
crimped by the top cover, nor should they hamper proper airflow inside the chassis.
Status LED indicators
This section describes the internal and external status LED indicators located on the front panel, rear panel, and
system board. These LED indicators aid in problem diagnosis by indicating the status of system components and
operations of the server.
Front panel LED indicators
The status LED indicators on the front panel allow constant monitoring of basic system functions while the server is
operating. These LEDs are mounted on the front panel board. Figure 77 shows and describes the function of
these LEDs.
