3. Unpack the power supply and verify that the power supply model is correct.
Put away the packaging box and packaging bag of the power supply for future use.
4. Correctly orient the power supply with the power supply slot (use the letters on the power supply
faceplate for orientation), grasp the handle of the power supply with one hand and support its
bottom with the other, and slide the power supply slowly along the guide rails into the slot until
you hear that the latch of the power supply clicks into the slot.
When you insert the power supply into the slot, you can do that through slight inertia so that the
terminals of the power supply can have good contact with the backplane.
The PSR1110-56A (JG544A) power supply adds 64 mm (2.52 in) to the depth of the switch, as
shown in Figure 27.
5. Install the filler panel ove
r the empty power supply slot to prevent dust and ensure good
ventilation if you install only one power supply.
