Common Installation Problems
The following sections contain general procedures to help you locate installation problems. If you need
assistance, HP recommends contacting your reseller first. If you need to get assistance from Hewlett-
Packard, refer to Warranty and Support document provided with the Netserver.
WARNING
Before removing the cover, always disconnect the power cord 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.
Troubleshooting Sequence
To troubleshoot problems during installation, do the following:
•
First, ensure the HP Netserver is configured properly.
Most Netserver problems are the result of incorrect Netserver 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 Netserver 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 Netserver or its
options.
Always replace one option, and only one option, at a time.
NOTE
If the Netserver has a large amount of memory installed, it may take 30 seconds for
the first screen to display.
Netserver Will Not Power On
Follow these steps if the power/activity light does not light green after you press the power-on button, or the
Netserver will not power on properly.
NOTE
If the heatsink is not properly installed on the processor or the cooling fan is not
connected to the fan power connection, the Netserver will automatically shut down
within 10 seconds and provide no error messages, error codes, beep codes, or
video display.
