5.2.1 Replacing a PSU

Caution:
When installing or replacing a PSU while power is being supplied, you must take
care in the operation procedures and safety with electricity. Do not touch any
exposed wires, terminals or any parts of the product marked with a dangerous
voltage label to avoid bodily injury.
The PSUs of the S9500 series are hot-swappable. Before removing a PSU, you
must turn off its power switch.
If you do not want to install a PSU, insert a blank filler panel into the PSU slot for
dust-proofing.
I. Removing a PSU other than NEPS3500-A
The following procedure applies to all NEPS PSUs except NEPS3500-A.
1) Move the power switch on the PSU to the OFF position if it is in the ON position.
Disconnect the power source and unplug the power cord.
2) Remove the captive screws on the both sides of the PSU panel with a Phillips
screwdriver.
3) Grasp the air filter cover by the upper and lower edges with your index finger and
the thumb, and gently remove the air filter cover.
4) Pull the PSU gently along the guides out of the chassis, as shown in Figure 5-1.
