Chapter 9 Troubleshooting Troubleshooting Sequence To troubleshoot problems during installation, do the following: • First, ensure the HP Server is configured properly. Most Server problems are the result of incorrect Server and SCSI configurations. • Verify all cables and boards are securely plugged into the appropriate connectors or slots. • If it is a network-related error, determine if the Server has enough memory and hard disk drive capacity. • Refer to the network operating system (NOS) manual. • Remove all added options to ensure you have isolated the problem to basic Server or its options. If you replace the options, always replace one and only one option at a time. NOTE If the Server has a large amount of memory installed, it may take 30 seconds for the first screen to display. Server Will Not Power On Follow these steps if the power LED does not light green after you press the power-on button, or the Server will not power on properly. NOTE If the heatsink is not properly installed on the processor, the processor may overheat causing intermittent or unreliable operation leading to a possible system crash and permanent damage to the processor. 1. Remove the AC power cord, wait 15 seconds, reconnect the power cord, and try again. 2. Ensure all cables and the power cord are firmly plugged into the proper receptacles. 3. If the Server is plugged into a switched multiple-outlet box, ensure the switch on the outlet box is turned on. 4. Plug a different electrical device (such as a printer) into the power outlet, and turn it on to verify if the fault is with the power supply. 71

Troubleshooting Sequence
To troubleshoot problems during installation, do the following:
•
First, ensure the HP Server is configured properly.
Most Server problems are the result of incorrect Server and SCSI
configurations.
•
Verify all cables and boards are securely plugged into the appropriate
connectors or slots.
•
If it is a network-related error, determine if the Server has enough memory
and hard disk drive capacity.
•
Refer to the network operating system (NOS) manual.
•
Remove all added options to ensure you have isolated the problem to basic
Server or its options.
If you replace the options, always replace one and only one option at a time.
NOTE
If the Server has a large amount of memory installed, it may
take 30 seconds for the first screen to display.
Server Will Not Power On
Follow these steps if the power LED does not light green after you press the
power-on button, or the Server will not power on properly.
NOTE
If the heatsink is not properly installed on the processor, the
processor may overheat causing intermittent or unreliable
operation leading to a possible system crash and permanent
damage to the processor.
1. Remove the AC power cord, wait 15 seconds, reconnect the power cord, and
try again.
2. Ensure all cables and the power cord are firmly plugged into the proper
receptacles.
3. If the Server is plugged into a switched multiple-outlet box, ensure the switch
on the outlet box is turned on.
4. Plug a different electrical device (such as a printer) into the power outlet, and
turn it on to verify if the fault is with the power supply.
