Introduction
If you are having problems with installing your HP Server or booting it up, this chapter provides
information on the different tools available for common installation problems, troubleshooting
operational problems and error messages.
Common Installation Problems
The following sections contain general procedures to help you locate installation problems.
WARNING Before removing the top cover, always disconnect the power cords and unplug
telephone cables. Disconnect telephone cables to avoid exposure to shock hazard
from telephone ringing voltages. Disconnect the power cord to avoid exposure to
high energy levels that may cause burns when parts are short-circuited by metal
objects such as tools or jewelry.
The power switch does NOT turn off the standby power. Disconnect the power
cord from the HP Server before handling components.
CAUTION Replace the top cover before operating the HP 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 HP 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 baseboard, power down the HP
Server and observe all safety precautions.
Troubleshooting Sequence
Most HP Server problems are the result of incorrect HP Server 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 HP Server is configured properly.
◊◊◊◊ Check the Setup Utility.
◊◊◊◊ If the error is a network-related problem, determine if the HP Server has enough memory
and hard disk drive capacity.
◊◊◊◊ Consult your network operating system manual.
3. Verify all cables and boards are securely plugged into the appropriate connectors or slots.
4. Remove all extra options one at a time, checking its affect on the HP Server.
5. Unplug the power cord, wait 20 seconds, plug the power cord in again, and restart the HP
Server.
