4: Replacing Enclosure Components
Replacing a Failed Power Supply Module
When instructed by TPSSM to replace a failed power supply module, read “Power
Supplies” on page 21, 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.
