If The System Will Not Power On; Troubleshooting Sequence - HP NetServer E 45 User Manual

Chapter 5
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.

If the System Will Not Power On

Follow these steps if the power/activity light does not light green after you press
the power-on button:
1. Check to ensure that all cables and power cords are firmly plugged into
their proper receptacles.
2. Check that the voltage switch is set to the correct setting for your country.
3. If the server is plugged into a switched multiple-outlet box, make sure 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 check if the fault is with the power supply.

Troubleshooting Sequence

To troubleshoot an installation problem, do the following:
•
First make sure that the system is configured properly. Most system
problems are the result of incorrect system and SCSI subsystem
configurations.
•
If it is a network-related error, determine if the server has enough memory
and hard disk drive capacity. Consult your network operating
system manual.
•
Verify that all cables and boards are securely plugged into their
appropriate connectors or slots.
•
Remove all added options and always change one thing, and only one
thing, 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.
