Set the rotary power switch on each power supply, as follows:
•
For an AC-input power supply—Set the switch to the Standby position.
•
For a DC-input power supply—Set the switch to the OFF (O) position.
Turning the rotary power switch to the Standby position on the AC-input
Note
power supply is equivalent to setting the same switch on the DC-input power
supply to the OFF position. In either case, turning the rotary power switch to the
full counterclockwise position releases a mechanical interlock (latching
mechanism), enabling you to remove the unit from the bay.
Using a flat-blade screwdriver, turn the captive installation screw on the power
supply faceplate counterclockwise until it is freed from the sheet metal flange of
the power supply bay.
Grasp the power supply carrying handle with one hand and pull the unit halfway
out of the bay (see Figure 3-3).
Use both hands in removing a power supply.
Place your free hand beneath the power supply to support its weight and slide
the unit completely out of the bay.
Set the power supply aside temporarily until you are ready to reinstall it
following completion of the rack-mounting procedure described in the following
section entitled "Rack-Mounting the Cisco 12008."
