Some products contain power supplies that are capable of producing hazardous energy levels. Refer to the
documentation included with your product to determine whether it contains these power supplies. 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.
•
Allow the product to cool before removing covers and touching internal components.
•
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, storage,
networking, or rack product.
•
Some products have covers or doors to access hot-plug components and may allow access to hazardous
energy circuits or moving fans.
•
The doors should remain locked during normal operation.
OR
•
The server, storage, networking, or rack product should be installed in a controlled access location where
only qualified personnel have access.
•
Power down the equipment and disconnect all power cords before removing any access covers for
non-hot-plug areas.
•
Do not replace non-hot-plug components while power is applied to the product. First, shut down the
product and disconnect all 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.
•
For floor-standing products, install and extend bottom stabilizers before installing options and boards.
•
Verify that the AC power supply branch circuit that provides power to the rack is not overloaded. This will
reduce 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.
