5 Troubleshooting This chapter contains information about the various status LEDs on the HP 9000 rp7420 server and other troubleshooting information. Common Installation Problems The following sections contain general procedures to help you locate installation problems. CAUTION: Replace the top cover before operating the server, even for a short time. Otherwise, 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 cards. For any other service activity requiring access to the processor baseboard or I/O backplane, power the server off, 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, and so on. 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 cords, wait 20 seconds, plug-in the power cords 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. 1. 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 them one at a time, checking the server after each installation. 8. Replace the top cover and reconnect the cables. Boot the server. If the server does not function properly, see "The Server Does Not Power On" (page 67).
