Removing and Replacing a Power-and-Cooling
Module
A single power-and-cooling module is sufficient to maintain operation of the
enclosure. It is not necessary to halt operations and completely power off the
enclosure when replacing only one power-and-cooling module.
Caution – When you remove a power-and-cooling module, install the new module
within two minutes of removing the old module. The enclosure might overheat if
you take more than two minutes to replace the power-and-cooling module.
Removing a Power-and-Cooling Module
To remove a power-and-cooling module from an enclosure, perform the following
steps:
1. Follow all static electricity precautions as described in “Static Electricity
Precautions” on page 80.
2. Turn the power switch off and disconnect the power cable.
3. Rotate the latch downward to disconnect the internal connector, and slide the
module out.
Note – Do not lift the power-and-cooling module by the latch. This could break the
latch. Hold the power-and-cooling module by the metal casing.
