Server Warnings and Precautions
WARNING: Hazardous voltages are present inside the server. Always disconnect AC
power from the server and other associated assemblies while working inside the unit.
Serious injury may result if this warning is not observed.
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.
•
Disconnect all power cords to completely remove power from the system.
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 power 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.
Hardware Configuration Information
Electrostatic Discharge Information
An electrostatic discharge (ESD) can damage static-sensitive devices or microcircuitry.
Proper packaging and grounding techniques are necessary precautions to prevent damage. To
prevent electrostatic damage, observe the following precautions:
•
Transport products in static-safe containers such as conductive tubes, bags, or boxes.
•
Keep electrostatic-sensitive parts in their containers until they arrive at static-free
stations.
•
Cover workstations with approved static-dissipating material. Use a wrist strap connected
to the work surface, and properly grounded (earthed) tools and equipment.
•
Keep work area free of nonconductive materials, such as ordinary plastic assembly aids
and foam packing.
