Server Warnings and Precautions

WARNING: To reduce the risk of personal injury from hot surfaces, allow the hot-plug

drives and the internal system components to cool before touching them.

WARNING: To reduce the risk of electric shock or damage to the equipment:

• Do not disable the power cord grounding plug. The grounding plug is an important

safety feature.

• Plug the power cord into a grounded (earthed) electrical outlet that is easily

accessible at all times.

• Unplug the power cord from the power supply to disconnect power to the

equipment.

CAUTION: Protect the server from power fluctuations and temporary interruptions with a

regulating uninterruptible power supply (UPS). This device protects the hardware from damage

caused by power surges and voltage spikes and keeps the system in operation during a powe

failure.

CAUTION: The server must always be operated with the system top cover closed. Proper

cooling is not achieved if the system top cover is removed.
