Server warnings and cautions
Before installing a server, be sure that you understand the following warnings and cautions.
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 from hot surfaces, allow the drives and the internal system components to cool before touching them.
WARNING: To reduce the risk of personal injury, electric shock, or damage to the equipment, remove the power cord to remove power from the server. The front panel Power On/Standby button does not completely shut off system power. Portions of the power supply and some internal circuitry remain active until AC power is removed.
CAUTION: Do not operate the server for long periods with the access panel open or removed. Operating the server in this manner results in improper airflow and improper cooling that can lead to thermal damage.
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.
Rack warnings and cautions
WARNING: To reduce the risk of personal injury or damage to the equipment, be sure that:
•The leveling jacks are extended to the floor.
•The full weight of the rack rests on the leveling jacks.
•The stabilizing feet are attached to the rack if it is a
•The racks are coupled together in
•Only one component is extended at a time. A rack may become unstable if more than one component is extended for any reason.
WARNING: To reduce the risk of personal injury or equipment damage when unloading a rack:
•At least two people are needed to safely unload the rack from the pallet. An empty 42U rack can weigh as much as 115 kg (253 lb), can stand more than 2.1 m (7 ft) tall, and may become unstable when being moved on its casters.
•Never stand in front of the rack when it is rolling down the ramp from the pallet. Always handle the rack from both sides.
