Pre-diagnostic steps
WARNING: To avoid potential problems, ALWAYS read the warnings and cautionary
information in the server documentation before removing, replacing, reseating, or modifying
system components.
IMPORTANT: This guide provides information for multiple servers. Some information may not
apply to the server you are troubleshooting. Refer to the server documentation for information
on procedures, hardware options, software tools, and operating systems supported by the
server.
1. Review the important safety information (on page 13).
2. Gather symptom information (on page 16).
3. Prepare the server for diagnosis (on page 16).
4. Use the Start diagnosis flowchart (on page 25) to begin the diagnostic process.
Important safety information
Familiarize yourself with the safety information in the following sections before troubleshooting the server.
Important safety information
Before servicing this product, read the Important Safety Information document provided with the server.

manual material handling.
These symbols, on power supplies or systems, indicate that the equipment is
supplied by multiple sources of power.
WARNING: To reduce the risk of injury from electric shock, remove all power
cords to completely disconnect power from the system.
Warnings and cautions
WARNING: Only authorized technicians trained by HP should attempt to repair this
equipment. All troubleshooting and repair procedures are detailed to allow only
subassembly/module-level repair. Because of the complexity of the individual boards and
subassemblies, no one should attempt to make repairs at the component level or to make
modifications to any printed wiring board. Improper repairs can create a safety hazard.
WARNING: To reduce the risk of personal injury or damage to the equipment, be sure that:
•The leveling feet are extended to the floor.
•The full weight of the rack rests on the leveling feet.
•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 electric shock or damage to the equipment:
•Do not disable the power cord grounding plug. The grounding plug is an important safety
feature.
•Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at
all times.
•Unplug the power cord from the power supply to disconnect power to the equipment.
•Do not route the power cord where it can be walked on or pinched by items placed
against it. Pay particular attention to the plug, electrical outlet, and the point where the
cord extends from the server.

Getting started 15
weight in kg
weight in lb
WARNING: To reduce the risk of personal injury or damage to the equipment:
•Observe local occupation health and safety requirements and guidelines for
manual handling.
•Obtain adequate assistance to lift and stabilize the chassis during installation or
removal.
•The server is unstable when not fastened to the rails.
•When mounting the server in a rack, remove the power supplies and any other
removable module to reduce the overall weight of the product.
CAUTION: To properly ventilate the system, you must provide at least 7.6 cm (3.0 in) of
clearance at the front and back of the server.
CAUTION: The server is designed to be electrically grounded (earthed). To ensure proper
operation, plug the AC power cord into a properly grounded AC outlet only.
Electrostatic discharge
Preventing electrostatic discharge
To prevent damaging the system, be aware of the precautions you need to follow when setting up the
system or handling parts. A discharge of static electricity from a finger or other conductor may damage
system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the
device.
To prevent electrostatic damage:
•Avoid hand contact by transporting and storing products in static-safe containers.
•Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
•Place parts on a grounded surface before removing them from their containers.
•Avoid touching pins, leads, or circuitry.
•Always be properly grounded when touching a static-sensitive component or assembly.
Grounding methods to prevent electrostatic discharge
Several methods are used for grounding. Use one or more of the following methods when handling or
installing electrostatic-sensitive parts:
•Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist
straps are flexible straps with a minimum of 1 megohm ±10 percent resistance in the ground cords.
To provide proper ground, wear the strap snug against the skin.
•Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet
when standing on conductive floors or dissipating floor mats.
•Use conductive field service tools.
•Use a portable field service kit with a folding static-dissipating work mat.
If you do not have any of the suggested equipment for proper grounding, have an authorized reseller
install the part.

reseller.
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 75) 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.
Prepare the server for diagnosis
1. Be sure the server is in the proper operating environment with adequate power, air conditioning,
and humidity control. For required environmental conditions, see the server documentation (on page
86).
2. Record any error messages displayed by the system.
3. Remove all diskettes, CD-ROMs, DVD-ROMs, and USB drive keys.
4. Power down the server and peripheral devices if you will be diagnosing the server offline. If
possible, always perform an orderly shutdown:
a. Exit any applications.
b. Exit the operating system.
c. Power down the server.
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.
6. Collect all tools and utilities, such as a Torx screwdriver, loopback adapters, ESD wrist strap, and
software utilities, necessary to troubleshoot the problem.
oYou must have the appropriate Health Drivers and Management Agents installed on the server.
To verify the server configuration, connect to the System Management homepage and select
Version Control Agent. The VCA gives you a list of names and versions of all installed HP drivers,
Management Agents, and utilities, and whether they are up-to-date.
oHP recommends you have access to the server documentation (on page 86) for server-specific
information.
oHP recommends you have access to the SmartStart CD for value-added software and drivers
required during the troubleshooting process. Download the current version of SmartStart from the
HP website (http://www.hp.com/servers/smartstart).

Breaking the server down to the minimum hardware configuration
During the troubleshooting process, you may be asked to break the server down to the minimum
hardware configuration. A minimum configuration consists of only the components needed to boot the
server and successfully pass POST.
When requested to break the server down to the minimum configuration, uninstall the following
components, if installed:
•All additional processors (leave one installed)
•All additional DIMMs
Leave only the minimum required to boot the server—either one DIMM or a pair of DIMMs. For more
information, see the memory guidelines in the server user guide.
•All additional cooling fans, if applicable
For minimum fan configuration, see the server user guide.
•All additional power supplies, if applicable (leave one installed)
•All hard drives
•All optical drives (DVD-ROM, CD-ROM, and so forth)
•All optional mezzanine cards
•All expansion boards
Before removing the components, be sure to determine the minimum configuration for each component
and follow all guidelines in the server user guide.

Loose connections
Action:
•Be sure all power cords are securely connected.
•Be sure all cables are properly aligned and securely connected for all external and internal
components.
•Remove and check all data and power cables for damage. Be sure no cables have bent pins or
damaged connectors.
•If a fixed cable tray is available for the server, be sure the cords and cables connected to the server
are routed correctly through the tray.
•Be sure each device is properly seated. Avoid bending or flexing circuit boards when reseating
components.
•If a device has latches, be sure they are completely closed and locked.
•Check any interlock or interconnect LEDs that may indicate a component is not connected properly.
•If problems continue to occur, remove and reinstall each device, checking the connectors and sockets
for bent pins or other damage.

DIMM handling guidelines
CAUTION: Failure to properly handle DIMMs can cause damage to DIMM components and
the system board connector.
When handling a DIMM, observe the following guidelines:
•Avoid electrostatic discharge (on page 15).
•Always hold DIMMs by the side edges only.
•Avoid touching the connectors on the bottom of the DIMM.
•Never wrap your fingers around a DIMM.
•Avoid touching the components on the sides of the DIMM.
•Never bend or flex the DIMM.
When installing a DIMM, observe the following guidelines:
•Before seating the DIMM, align the DIMM with the slot.
•To align and seat the DIMM, use two fingers to hold the DIMM along the side edges.
•To seat the DIMM, use two fingers to apply gentle pressure along the top of the DIMM.

Hard drive guidelines
SAS and SATA hard drive guidelines
When adding hard drives to the server, observe the following general guidelines:
•The system automatically sets all drive numbers.
•If only one hard drive is used, install it in the bay with the lowest drive number.
•Drives must be the same capacity to provide the greatest storage space efficiency when drives are
grouped together into the same drive array.
•Drives in the same logical volume must be of the same type:
oACU does not support mixing SAS and SATA drives in the same logical volume.
oACU does not support mixing traditional drives and solid state drives (SSD) in the same logical
volume.
SCSI hard drive guidelines
•Each SCSI drive must have a unique ID.
•The system automatically sets all SCSI IDs.
•If only one SCSI hard drive is used, install it in the bay with the lowest number.
