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 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, the
processor may overheat causing intermittent or unreliable
operation leading to a possible system crash and permanent
damage to the processor.
