Removal and Replacement Procedures
WARNING: Be sure that the AC power supply branch circuit that provides power to the
rack is not overloaded. Not overloading AC power to the rack power supply circuit
reduces the risk of personal injury, fire, or damage to the equipment. The total rack
load should not exceed 80 percent of the branch circuit rating. Consult the electrical
authority having jurisdiction over your facility wiring and installation requirements.
WARNING: To reduce the risk of personal injury or damage to the equipment, the
installation of options other than hot-plug power devices should be performed only by
individuals who are qualified in servicing computer equipment and trained to deal with
products capable of producing hazardous energy levels.
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 system.
• Do not use conductive tools that could bridge live parts.
• Remove all watches, rings, or loose jewelry when working in hot-plug areas of an
energized device.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives
and the internal system components to cool before touching them.
CAUTION: Protect the device 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.
