Replacing a Failed PSU Module
5.5.2 Replacing the PSU Module
WARNING!
Before you insert a new PSU, be sure that it has the same warning label on its
extraction handle as that shown on the lever of a remaining PSU. Double-check to
avoid mixing a similar yet different PSU of another Galaxy series.
To replace a PSU, please follow these steps:
Step 1.
Power off the PSU
. The power switch is located on each PSU’s rear-
facing panel. (See
Figure 5-9
)
Step 2.
Disconnect the power cord
that connects the PSU to the main power
source.
Step 3.
Remove the retention screw
that secures the rejection handle to the
chassis. (See
Figure
5-10:
Removing the PSU Retention Screw
.)
