Replacing a Failed Power Supply Module

52
When instructed by TPSSM to replace a failed power supply module, read "Power Supplies" on
page 23, and then follow these steps:
Warning:
Electrostatic discharge can damage sensitive components. Use a grounded
wrist strap or other antistatic precautions before handling enclosure components.
1. Check TPSSM for instructions on power supply failure recovery procedures. Follow any
instructions provided before you proceed.
2. Unpack the new power supply module. Set the new power supply module on a dry, level
surface near the enclosure. Save all packing materials in case you need to return the module.
3. Review all documentation shipped with the new power supply module for updated
replacement procedures and other information. If necessary, modify the remaining steps to
meet the system requirements. Kits often contain the most current servicing information. If
the kit instructions conflict with those in this procedure, follow the kit instructions.
Danger:
Shock can occur. Make sure the power supply is turned off and unplugged
before you remove or install it.
4. Locate the failed power supply (its fault light should be on).
5. Turn off the power and unplug the power cord from the failed module.
6. Remove the power cord from the power cord clip.
7. Wearing antistatic protection, grasp the pull-ring on the locking lever and squeeze the tab
against the ring to unlatch the lever (see Figure 4-4).
8. Pull open the lever and remove the failed module.
9. Check the lever to make sure the orientation is the same as the module it is replacing. If not,
move the lever to the pivot post on the other side.
