Replacement Guidelines and Precautions
Preparing to Replace the Power Supply
Perform these preparatory steps before you attempt to replace a power supply:
Review these important notes and cautions:
Before handling any CRU, obtain an electrostatic discharge (ESD) protection kit.
Follow the directions on the kit for replacing a CRU to prevent damage to system
components. ●
Power cords might contain faulty connectors that, when touched, vibrated, or flexed, can
cause intermittent power or the loss of a processor. ●
Before replacing a power supply, visually check the power cord without touching the
power cord. If the power cord molding is elliptical rather than square, or if the power
cord part number is TPN 064583, you must replace the power cord offline with power
cord TPN 421575 before you can replace the power supply. For power cord replacement
instructions, refer to the Support and Service > Service Procedures collection of NTL. If
you are replacing both the power cord and the power supply, install the replacement
power cord before installing the replacement power supply. ●
Handle with care -- the power supply weighs approximately 5.6 kilograms (14 pounds). ●
Follow these standard operating practices when replacing CRUs:
Replace only one CRU at a time. Attempting to replace more than one hardware
component at a time might cause serious system outages, processor halts, and
connectivity problems. ❍
Remove all jewelry and metal accessories, such as rings, watches, and necklaces,
before working with the equipment. These items can damage electrical equipment
or result in personal injury. ❍
Restrain any dangling items that can get caught in electromechanical equipment,
such as long hair and sleeves, before working with the equipment. ❍
