Replacing a Failed Power/Fan Module
007-4834-001 47
4. Review all documentation shipped with the new power/fan module for any
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.
5. If TPSSM instructs you to do so, turn off the power to the enclosure. Otherwise,
leave the power on.
Caution: To prevent the enclosure from overheating while in use, complete the
power/fan module replacement procedure within 15 minutes from the time you
remove the failed module to the time you install the new module. Both power/fan
modules must be installed in the enclosure to provide continuous power and air
circulation within the enclosure.
6. Locate the failed power/fan module (its fault light should be on).
7. Turn off the power switch, and unplug the power cord from the failed power/fan
module.
8. Wearing antistatic protection, pull the latch handle outward to unlock the module
(see callout 1 in Figure 4-2). The latch handle is at the top of the left-side power/fan
module, and at the bottom of the right-side power/fan module.
