Figure 50 Remove the power module
1: Loosen the captive screw 2: Pull the power module out
3: Fasten the screw on the air filter (optional)
CAUTION:
• The power module of the S7500E series is heavy. When pulling the power module out of the slot,
support the bottom of the power module with one hand and hold the handle of the power module
with
the other.
• After removing the power module, if you do not install a new power module, install a blank panel. As
shown in callout 3 on Figure 50, ali
n the screws on the blank panel with the screw holes on the switch,
and then use a screwdriver to fasten the screws on the blank panel.
NOTE:
If the power module to be removed is in a power adapter, and the power module to be installed does no
need a power adapter, remove the power adapter after removing the power module. The procedures for
removing a power adapter are the same as removing a power module.
