After clicking Yes to confirm that you are ready to proceed with the replacement action:
OSM checks the peer power supply to verify that it is functional and can take over
during the replacement. ●
If the peer power supply is functional, OSM disables the battery associated with the
power supply CRU to be replaced. ●
If these tasks complete successfully, a dialog box informs you that the power supply is
ready to be replaced. ●
2.
After replacing the power supply CRU, click Continue to complete the action. OSM verifies
the status of the new power supply. If it is functional, OSM enables the battery that was
disabled earlier in the procedure. 3.
If at any point during the procedure OSM finds problems that prevent the action from completing (or
make continuing unadvisable), a dialog box reports the problems that must be addressed before the
CRU replacement can be safely completed.
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 Replacing an S7x000 Power Cord on the
CSSI Web . 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 ❍
