Observe the server LEDs and their statuses. See the LED Indicators for more information.
8.1.3. Prepare the Server for Diagnosis
1.
Be sure that the server is in the proper operating environment with adequate power, air conditioning, and
humidity control. For required environmental conditions, see the server documentation.
2.
Record any error messages displayed by the system.
3.
Remove all external peripherals such as the network cables, monitor, keyboard, and mouse.
4.
Collect all tools and utilities necessary to troubleshoot the problem, such as a Cross screwdriver, loopback
adapters, ESD wrist strap, and software utilities.
5.
Determine if the server will troubleshoot offline or online.
6.
To diagnose the server offline, power down the server and peripheral devices. If possible, always perform an
orderly shutdown:
7.
Exit any applications.
8.
Exit the operating system.
9.
Power down the server.
10. Disconnect any peripheral devices not required for testing (any devices not necessary to power up the
server).
8.1.4. 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 installation, removal,
or replacement of a processor.
Never touch the contacts in the processor socket. THE PINS ON THE SYSTEM BOARD ARE VERY FRAGILE AND
EASILY DAMAGED. If the contacts inside the processor socket are damaged, you must replace the system
board.
Some processor models require the use of a processor installation tool, and specific steps are documented
to ensure that they 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 the socket is damaged, you must replace the system board.
Always complete all other troubleshooting procedures before removing or replacing a processor.
8.1.5. Breaking the Server down to the Minimum Hardware Configuration
During the troubleshooting process, it might be necessary to break down the server 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 DIMMs
Leave only the minimum required to boot the server—one DIMM.
All additional cooling fans, if applicable
All hard drives
Before removing the components, be sure to determine the minimum configuration for each component and follow
all guidelines in the server user and maintenance guide.
Always use the recommended minimum configuration above before removing any processors. If you are unable to
isolate the issue with the configuration above, you will then remove all but one of the processors.
Before removing or replacing any processors, be sure to follow the guidelines
provided in removing and installing processors steps.
Failure to follow the recommended guidelines can cause damage to the system board,
requiring replacement of the system board.
