12 Troubleshooting

Precautions

WARNING
Before removing the top 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.
Note that the power switch does NOT turn off the standby
power. Disconnect the power cord from the HP NetServer
before handling components.
CAUTION Replace the top cover before operating the HP NetServer,
even for a short time. Otherwise, overheating can damage
chips, boards, and mass storage devices.
However, you can safely remove the PCI Hot Plug access
panel while the system is running to remove and replace PCI
Hot Plug boards. For any other service activity that requires
access to the processor baseboard or I/O baseboard, power
down the system and observe all precautions listed above.
