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.
• Do not route the power cord where it can be walked on or pinched by items placed against it.
Pay particular attention to the plug, electrical outlet, and the point where the cord extends from
the server.

WARNING: To reduce the risk of personal injury or damage to the equipment:
• Observe local occupation health and safety requirements and guidelines for manual
handling.
• Obtain adequate assistance to lift and stabilize the chassis during installation or
removal.
• The server is unstable when not fastened to the rails.
• When mounting the server in a rack, remove the power supplies and any other
removable module to reduce the overall weight of the product.
CAUTION: To properly ventilate the system, you must provide at least 7.6 cm (3.0 in) of
clearance at the front and back of the server.
CAUTION: The server is designed to be electrically grounded (earthed). To ensure proper
operation, plug the AC power cord into a properly grounded AC outlet only.
Electrostatic discharge
Preventing electrostatic discharge
To prevent damaging the system, be aware of the precautions you need to follow when setting up the system
or handling parts. A discharge of static electricity from a finger or other conductor may damage system
boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device.
To prevent electrostatic damage:
• Avoid hand contact by transporting and storing products in static-safe containers.
• Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
• Place parts on a grounded surface before removing them from their containers.
• Avoid touching pins, leads, or circuitry.
• Always be properly grounded when touching a static-sensitive component or assembly.
Grounding methods to prevent electrostatic discharge
Several methods are used for grounding. Use one or more of the following methods when handling or
installing electrostatic-sensitive parts:
• Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist
straps are flexible straps with a minimum of 1 megohm ±10 percent resistance in the ground cords. To
provide proper ground, wear the strap snug against the skin.
