HP Integrity rx7620 Server - User Service Guide, Sixth Edition

5 Troubleshooting
This chapter provides preferred strategies, procedures, and tools for troubleshooting server error
and fault conditions.
Common Installation Problems
This section provides basic server troubleshooting information. It is designed to help you diagnose
common issues that can occur during server installation.
CAUTION: Replace the top cover before operating the server, even for a short time. Overheating
can damage chips, boards, and mass storage devices. However, you can safely remove the PCI
access panel while the server is running to remove and replace PCI hot-plug boards. For any
other service activity requiring access to the processor baseboard or I/O backplane, power off
the server and observe all safety precautions.
Most problems are the result of incorrect system and SCSI subsystem configurations.
To troubleshoot an installation problem, perform the following checks in the order given:
1. Check all cable and power connections, including those in the rack.
2. Ensure the server is configured properly.
Check the Setup Utility. If the error is a network-related problem, determine if the server
has enough memory and hard disk drive capacity.
3. Verify all cables and boards are securely plugged in to the appropriate connectors or slots.
4. Remove all extra options, such as disk drives, one at a time, checking the affect of each on
the server.
5. Unplug the power cord, wait 20 seconds, plug-in the power cord and restart the server.
6. If a hardware error is suspected, follow these steps:
a. Log users off the LAN and power off the server.
b. Extend the server out of the rack and remove the top cover.
c. Simplify the server to the minimum configuration.
The minimum configuration consists of the following:
• One cell
• Two processors
• One quad of memory DIMMS (size 256 MB or larger)
• One MP/SCSI card
• One LAN/SCSI card
• System backplane
• PCI-X backplane
• One BPS
• Two PCI power modules
• Two power cords
7. Remove all third-party options and reinstall each one, one at a time, checking the server
after each installation.
8. Replace the top cover and reconnect the power cord and other cables. Boot the server. If it
does not function properly, see the procedures in the following section.
