Removal and Replacement Procedures 2-7 Server Warnings and Precautions 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: To reduce the risk of electric shock or damage to the equipment: Allow the product to cool before removing covers and touching internal components. 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 power from the server by unplugging the power cord from either the electrical outlet or the server. 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. Understand the hot-plug access panel provides access to hazardous energy circuits. Understand the panel should remain locked during normal operation. -OrInstall the server in a controlled access location where only qualified personnel have access to the server. Power down the equipment and disconnect power to all AC power cords before removing any access covers for non-hot-pluggable areas. Do not replace non-hot-pluggable components while power is applied to the product. First, shut down the product and disconnect all AC power cords. 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. Verify 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. 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 ProLiant DL580 server must always be operated with the system unit cover on. Proper cooling is not achieved if the system unit cover is removed.
