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 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.
