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:

Step 1 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.

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.

Step 2 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.

Step 3 Grasp the power supply carrying handle with one hand and pull the unit halfway out of the bay (see Figure 3-3).

Caution Use both hands in removing a power supply.

Step 4 Place your free hand beneath the power supply to support its weight and slide the unit completely out of the bay.

Step 5 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.”
