Reinstalling Components in the Router

To reinstall a power supply that was removed prior to rack mounting the router, perform the following steps:

Step 1 Verify that the rotary power switch on the power supply to be reinstalled is set, as follows:

•

•

For an AC-input power supply—Set to the Standby position.

For a DC-input power supply—Set to the OFF position.

Note Turning the rotary power switch to the Standby position for the AC-input power supply is operationally 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 retracts a mechanical interlock into the body of the power supply, thus enabling you to insert the power supply into the power supply bay.

Step 2 Grasp the power supply carrying handle with one hand.

Caution The AC-input power supply weighs 17 lb (7.72 kg); the DC-input power supply weighs 14 lb (6.36 kg). Use both hands when handling these units.

Step 3 While lifting the power supply by its carrying handle, place your free hand beneath the unit to support its weight.

Step 4 Position the power supply appropriately for insertion into the power supply bay.

Note If you are reinstalling only a single AC-input or DC-input power supply, it is recommended that you install the unit in the bottom bay.

Step 5 Gently slide the power supply into the bay until its faceplate meets the sheet metal flange of the power supply bay.
