Troubleshooting 76

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 (on page 19).

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.

o You 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.

o HP recommends you have access to the server documentation for server-specific information.

o HP 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).

Performing processor procedures in the troubleshooting process

Before performing any troubleshooting steps that involve processors, review the following guidelines:

• Be sure that only authorized personnel perform the troubleshooting steps that involve installing,

removing, or replacing a processor.

• Always locate the documentation for your processor model before performing any steps that require

installing, removing, or replacing a processor. If you cannot locate the hard copy of the instructions that

shipped with the processor, see the processor instructions in this document.

• Some processor models require the use of a processor installation tool, and specific steps are

documented to ensure that you do not damage the processor or processor socket on the system board.

For server models that have pins inside the processor socket, remember that THE PINS ON THE SYSTEM

BOARD ARE VERY FRAGILE AND EASILY DAMAGED. If you damage the socket, you must replace the

system board.

• Depending on the server model, the contacts may be on the processor or they may be inside the

processor socket. Never touch the contacts. THE PINS ON THE SYSTEM BOARD ARE VERY FRAGILE AND

EASILY DAMAGED. If the contacts inside the processor socket are damaged, the system board must be

replaced.

• Always complete all other troubleshooting procedures before removing or replacing a processor.

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.
