Reinstalling Components in the Router
Cisco 12008 Gigabit Switch Router Installation and Configuration Guide
3-16
To reinstall a power supply that was removed prior t o rack mounting the router , perform the
following steps:
Step1 Verify that the rotary power switch on the power supply to be reinstalled is set,
as follows:
For an AC-input power supplySet to the Standby position.
For a DC-input power supplySet 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.
Step2 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 h andling these units.
Step3 While lifting the power supply by its carrying handle, place your free hand
beneath the unit to support its weight.
Step4 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.
Step5 Gently slide the power supply into the bay until its faceplate meets the sheet
metal flange of the power supply bay.
