4 Carefully slide the PSU the rest of the way out of the switch.
CAUTION
Power supplies may become very hot during operation. Wear thermal protective gloves when you remove a power
supply from an operating switch.
NOTE
If you are not installing a replacement PSU, install a cover over the unoccupied power supply bay. Unoccupied bays
must always be covered to maintain proper system ventilation and EMI levels.
5 Verify that the replacement PSU is right side up, with the latching tab at the right of the unit
(see Figure 172).
6 Carefully slide the PSU all the way into the power supply bay (see Figure 172). Push the PSU in until
the latch snaps into place.
