Troubleshooting Tips

WARNING Before removing a cover, always disconnect the power cords and unplug telephone cables. Disconnect telephone cables to avoid exposure to shock hazard from telephone ringing voltages. Disconnect the power cords to avoid exposure to high energy levels that may cause burns when parts are short-circuited by metal objects such as tools or jewelry.

CAUTION Do NOT operate the HP NetServer for more than 60 minutes with any cover (including power supplies and disk drives) removed. Otherwise, damage to system components may result due to improper cooling airflow.

However, you can safely remove a cover while the HP NetServer is running to remove and replace PCI Hot Plug boards. For any other service activity requiring access to the processor board or I/O board, power down the HP NetServer and observe all safety precautions.

For problems with the disk array controller board, refer to the appropriate HP NetRAID manuals.
