Removing Components from the Router
Removing a Power Supply from the Router
The router is shipped with all the circuit boards and the AC-input or the DC-input power
supply(ies) already installed, as ordered, but without any cables connected.
To remove a power supply from the router, perform the following steps:
Step1 Set the rotary power switch on each power supply, as follows:
For an AC-input power supplySet the switch to the Standby position.
For a DC-input power supplySet the switch to the OFF (O) position.
Note Turning the rotary power switch to the Standby position on the AC-input
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.
Step2 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.
Step3 Grasp the power supply carrying handle with one hand and pull the uni t halfway
out of the bay (see Figure3-3).
Caution Use both hands in removing a power supply.
Step4 Place your free hand beneath the power supply to support its weight and slide
the unit completely out of the bay.
Step5 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.
