2.
Unpack the power module and verify that the power module model is correct.
Put away the packaging box and packaging bag of the power module for future use.
3.
Correctly orient the power module with the power module slot (use the letters on the power module
faceplate for orientation), grasp the handle of the power module with one hand and support its
bottom with the other, and slide the power module slowly along the guide rails into the slot until
you hear that the latch of the power module clicks into the slot.
When you insert the power module into the slot, you can do that through slight inertia so that the
terminals of the power module can have a good touch with the backplane.
The PSR1110-56A power module adds 64 mm (2.52 in) to the depth of the switch, as shown
in
Figure 37

Install the filler module over the empty power module slot to prevent dust and ensure good
ventilation if you install only one power module.
