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 which may lead to a 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 Netserver 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.
5. Verify the power supply is connected to the system board.
6. Verify the front power switch is connected to the system board.
Problems after Netserver is Powered On
If you think it is a hardware error, follow these steps and refer to "Hardware
Problems" later in this chapter.
1. Log users off the network and power down the HP Netserver.
2. Remove the Netserver's cover.
WARNING Before removing the cover, always unplug telephone cables
and disconnect the power cord. Unplug 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.
3. Simplify the HP Netserver configuration to the required minimum, removing
all third-party options .
