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 boards. For any
other service activity requiring access to the processor baseboard or I/O backplane, power down
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, etc.
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 into the appropriate connectors or slots.
4. Remove all extra options such as disk drives one at a time, checking its affect on the server.
5. Unplug the power cord, wait 20 seconds, plug the power cord in again, and restart the server.
6. If you suspect a hardware error, follow these steps:
a. Log users off the LAN and power down the server.
b. Extend the server out of the rack and remove the top cover.
c. Simplify the hp rp7405/rp7410 to the minimum configuration.
The minimum configuration consists of the following:
•One cell
• Two processors
• One quad of memory DIMMS (size 256MB or larger)
• One MP/SCSI card
• One LAN/SCSI card
•System Backplane
• PCI 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.
