party rack is used, observe the following additional requirements to ensure

proper ventilation.
Rack server
To allow for servicing and adequate airflow, observe the following space and airflow requirements when

deciding where to install a rack:

• Leave a minimum clearance of 63.5 cm (25 in) in front of the rack.

• Leave a minimum clearance of 76.2 cm (30 in) behind the rack.

• Leave a minimum clearance of 121.9 cm (48 in) from the back of the rack to the back of another rack

or row of racks.

HP servers draw in cool air through the front door and expel warm air through the rear door. Therefore, the
front and rear rack doors must be adequately ventilated to allow ambient room air to enter the cabinet, and
the rear door must be adequately ventilated to allow the warm air to escape from the cabinet.

CAUTION: To prevent improper cooling and damage to the equipment, do not block the

When vertical space in the rack is not filled by a server or rack component, the gaps between the
components cause changes in airflow through the rack and across the servers. Cover all gaps with blanking
panels to maintain proper airflow.

ventilation openings.

CAUTION: Always use blanking panels to fill empty vertical spaces in the rack. This arrangement

lead to thermal damage.

The 9000 and 10000 Series Racks provide proper server cooling from flow-through perforations in the front
and rear doors that provide 64 percent open area for ventilation.

CAUTION: When using a Compaq branded 7000 series rack, install the high airflow rack door

insert (PN 327281-B21 for 42U rack, PN 157847-B21 for 22U rack) to provide proper
front-to-back airflow and cooling.

CAUTION: If a third-

adequate airflow and to prevent damage to the equipment:

• Front and rear doors—If the 42U rack includes closing front and rear doors, you must allow

5,350 sq cm (830 sq in) of holes evenly distributed from top to bottom to permit adequate
airflow (equivalent to the required 64 percent open area for ventilation).

• Side—The clearance between the installed rack component and the side panels of the rack

must be a minimum of 7 cm (2.75 in).

Temperature requirements

To ensure continued safe and reliable equipment operation, install or position the system in a well-ventilated,
climate-controlled environment.

The maximum recommended ambient operating temperature (TMRA) for most server products is 35°C
(95°F). The temperature in the room where the rack is located must not exceed 35°C (95°F).

Server setup 8

CAUTION: To reduce the risk of damage to the equipment when installing third-party options:

• Do not permit optional equipment to impede airflow around the server or to increase the

internal rack temperature beyond the maximum allowable limits.

• Do not exceed the manufacturer’s TMRA.

Power requirements

Installation of this equipment must comply with local and regional electrical regulations governing the
installation of information technology equipment by licensed electricians. This equipment is designed to
operate in installations covered by NFPA 70, 1999 Edition (National Electric Code) and NFPA-75, 1992
(code for Protection of Electronic Computer/Data Processing Equipment). For electrical power ratings on
options, refer to the product rating label or the user documentation supplied with that option.

WARNING: To reduce the risk of personal injury, fire, or damage to the equipment, do not

overload the AC supply branch circuit that provides power to the rack. Consult the electrical

When installing more than one server, you may need to use additional power distribution devices to safely
provide power to all devices. Observe the following guidelines:

authority having jurisdiction over wiring and installation requirements of your facility.

CAUTION: Protect the server from power fluctuations and temporary interruptions with a

regulating uninterruptible power supply. This device protects the hardware from damage caused
by power surges and voltage spikes and keeps the system in operation during a power failure.

• Balance the server power load between available AC supply branch circuits.

• Do not allow the overall system AC current load to exceed 80 percent of the branch circuit AC current

rating.

• Do not use common power outlet strips for this equipment.

• Provide a separate electrical circuit for the server.

Electrical grounding requirements

The server must be grounded properly for proper operation and safety. In the United States, you must install
the equipment in accordance with NFPA 70, 1999 Edition (National Electric Code), Article 250, as well as
any local and regional building codes. In Canada, you must install the equipment in accordance with
Canadian Standards Association, CSA C22.1, Canadian Electrical Code. In all other countries, you must
install the equipment in accordance with any regional or national electrical wiring codes, such as the
International Electrotechnical Commission (IEC) Code 364, parts 1 through 7. Furthermore, you must be sure
that all power distribution devices used in the installation, such as branch wiring and receptacles, are listed
or certified grounding-type devices.

Because of the high ground-leakage currents associated with multiple servers connected to the same power
source, HP recommends the use of a PDU that is either permanently wired to the building’s branch circuit or
includes a nondetachable cord that is wired to an industrial-style plug. NEMA locking-style plugs or those
complying with IEC 60309 are considered suitable for this purpose. Using common power outlet strips for
the server is not recommended.

Rack warnings

Server setup 9

WARNING: To reduce the risk of personal injury or damage to the equipment, be sure that:

• The leveling jacks are extended to the floor.

• The full weight of the rack rests on the leveling jacks.

• The stabilizing feet are attached to the rack if it is a single-rack installation.

• The racks are coupled together in multiple-rack installations.

• Only one component is extended at a time. A rack may become unstable if more than one

component is extended for any reason.

WARNING: To reduce the risk of personal injury or equipment damage when unloading a rack:

• At least two people are needed to safely unload the rack from the pallet. An empty 42U rack

can weigh as much as 115 kg (253 lb), can stand more than 2.1 m (7 ft) tall, and might
become unstable when being moved on its casters.

• Never stand in front of the rack when it is rolling down the ramp from the pallet. Always handle

the rack from both sides.

Installing hardware options

Memory options

Interleaving and non-interleaving memory configuration

Installing DIMMs

For server-specific memory installation guidelines, refer to the installation sheet that ships with the server.

This server supports both interleaving and non-interleaving memory configurations. Interleaving memory
increases bandwidth by allowing simultaneous access to more than one block of data (for example,
overlapping Read-Writes). This is accomplished by dividing the system memory between pairs of DIMMs and
Writing-Reading blocks of data to/from both simultaneously. In order to take advantage of memory
interleaving, identical DIMMs must be installed in pairs. DIMMs can also be installed singularly in slot 1 only
if memory interleaving is not desired.

Symptom information

Before troubleshooting a server problem, collect the following information:

• What events preceded the failure? After which steps does the problem occur?

• What has been changed since the time the server was working?

• Did you recently add or remove hardware or software? If so, did you remember to change the

appropriate settings in the server setup utility, if necessary?

• How long has the server exhibited problem symptoms?

• If the problem occurs randomly, what is the duration or frequency?

To answer these questions, the following information may be useful:

• Run HP Insight Diagnostics (on page 48) and use the survey page to view the current configuration or

to compare it to previous configurations.

• Refer to your hardware and software records for information.

• Refer to server LEDs and their statuses.

Preparing the server for diagnosis

1. Be sure the server is in the proper operating environment with adequate power, air conditioning, and

humidity control. Refer to the server documentation for required environmental conditions.

2. Record any error messages displayed by the system.

3. Remove all diskettes and CDs from the media drives.

4. Power down the server and peripheral devices if you will be diagnosing the server offline. Always

perform an orderly shutdown, if possible. This means you must:

a. Exit any applications.
b. Exit the operating system.
c. Power down the server (on page 6).

5. Disconnect any peripheral devices not required for testing (any devices not necessary to power up the

server). Do not disconnect the printer if you want to use it to print error messages.

work on issues and resolve problems without taking servers offline.

Troubleshooting 91

The process of updating system or option firmware is referred to as a flash process or flashing the ROM. A
firmware or ROM flash removes the existing version of firmware from the ROM and replaces it with a more
recent version.

Update the firmware to do the following:

• Support new hardware, such as a processor revision

• Support new features

• Correct problems in a previous firmware version

Without the correct firmware version, the server and hardware options may not function properly.

Types of ROM

Types of ROMs include:

• System ROM (on page 92)

This procedure is most effective when flashing the ROM on a small number of servers located in close
proximity.

Troubleshooting 92

To flash the ROM using ROMPaq:

1. Download the system ROMPaq utility diskette or USB drive key for each target server. ROMPaq

downloads are available on the HP website (http://www.hp.com/support).

2. Shut down each target server, and then reboot using the correct ROMPaq diskette or USB drive key for

that server.

3. Follow the interactive session in the ROMPaq utility, and then select the devices to be flashed.

4. After the ROMPaq utility flashes the ROM for the selected devices, cycle power manually to reboot the

system back into the operating system.

Option ROMPaqs have been retired as an upgrade delivery method for storage options. Firmware upgrades
for storage options are now delivered using Smart Components and Smart Component deployment utilities.

For additional information about the ROMPaq utility, see the server documentation or the HP website
(http://www.hp.com/support).

ROMPaq Disaster Recovery

If both the up-to-date and backup versions of the ROM are corrupt, perform ROMPaq Disaster Recovery
procedure:

1. On another server, download and save the ROMPaq image from the HP website

(http://www.hp.com/support) to a USB flash media device.

2. Execute the ROMPaq image to create the ROMPaq USB key.

3. Switch to the server with the corrupted ROM.

4. Power down the server (on page 6).

5. Insert the ROMPaq USB key.

6. Power up the server (on page 6).

7. Verify that the activity LED in the ROMPaq USB key is flashing. This indicates that BIOS has detected a

valid ROMPaq image

8. The ROMPaq disk flashes both system ROM images.

If an audible beep is generated every four seconds, repeat the process from step 4 until BIOS
successfully boots to the ROMPaq USB key.

Allow five minutes for the recovery procedure to be completed.

9. Power down the server (on page 6).

10. Remove the ROMPaq USB key.

11. Power up the server (on page 6).

The ROM recovery procedure is complete.

marketing name or model number of the product.

Part 15 of the Federal Communications Commission (FCC) Rules and Regulations has established Radio
Frequency (RF) emission limits to provide an interference-free radio frequency spectrum. Many electronic
devices, including computers, generate RF energy incidental to their intended function and are, therefore,
covered by these rules. These rules place computers and related peripheral devices into two classes, A and
B, depending upon their intended installation. Class A devices are those that may reasonably be expected
to be installed in a business or commercial environment. Class B devices are those that may reasonably be
expected to be installed in a residential environment (for example, personal computers). The FCC requires
devices in both classes to bear a label indicating the interference potential of the device as well as additional
operating instructions for the user.

FCC rating label

The FCC rating label on the device shows the classification (A or B) of the equipment. Class B devices have
an FCC logo or ID on the label. Class A devices do not have an FCC logo or ID on the label. After you
