Removing Power Supplies
Procedure
Step 1 Turn off the power to the power supply that you are removing, as follows:
a) If you are removing a DC-input power supply, ensure that the power is turned off at the power source by
turning off the power for that circuit.
Step 2
Detach the power and ground cables, as follows:
• For the AC-input power supply, unplug the power cables that are attached to the power supply and the
power source.
• For the DC-input power supply, remove the power cables from the power source.
Step 3
Remove the power supply from the chassis, as follows:
a) Press the ejector latch on the right of the power supply.
b) Pull the power supply partially out of the slot by its handle.
c) Pull the power supply fully from the slot.
If you intend to operate the switch without installing another power supply in the empty slot, then
you must reinstall the blank cover over the empty power supply slot to ensure proper air flow in the
system and for safety reasons. Caution
