Removal and Replacement Procedures
CAUTION: Always begin by mounting the heaviest item on the bottom of the rack. Continue
to populate the rack from the bottom to the top.
Server Warnings and Cautions
WARNING: Do not exceed the level of repair specified in the procedures in the product
documentation. All troubleshooting and repair procedures are detailed to allow only
subassembly or module-level repair. Because of the complexity of the individual
boards and subassemblies, do not attempt to make repairs at the component level or to
make modifications to any printed wiring board. Improper repairs can create a safety
hazard.
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.
WARNING: To reduce the risk of electric shock or damage to the equipment:
• Do not disable the AC 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 each power supply to disconnect power to the
equipment.
WARNING: The installation of internal options and routine maintenance and service of
this product should be performed by individuals who are knowledgeable about the
procedures, precautions, and hazards associated with equipment containing
hazardous energy levels.
WARNING: 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 server.
WARNING: Do not replace non-hot-plug components while power is applied to the
product. First, shut down the product and disconnect all AC power cords.
WARNING: Be sure that the AC power supply branch circuit that provides power to the
rack is not overloaded. Maintaining a low electrical current draw 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 for wiring and installation requirements.
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: Do not operate the server for extended periods without the access panel.
Operating the server without the access panel results in improper airflow and improper cooling
that can lead to thermal damage.
