• 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.
2. Unpack and inspect the replacement power supply. Use a flashlight to examine the pins on
the power supply's backplane connector for any damage. If any pins are bent or broken, you
must order another power supply (or have the backplane connector repaired or replaced)
before continuing with this procedure. Refer to Avoiding Connector and Backplane Damage
During CRU/FRU Replacement in the Support and Service > Service Procedures collection of
NTL.
Removing the Power Supply
1. Remove the front panel from the power shelf.
2. Locate the power supply you are removing (power supplies are in slots 31 and 32). At this
point, the LED above the power supply you are removing might or might not be lit. This
illustration shows an S7x000 processor enclosure. For an illustration of an IOMF2 CRU, see
the NonStop S-Series Hardware Installation and FastPath Guide.
