Cisco Systems Cisco 12008 manual Adding, Removing, or Replacing an AC-Input Power Supply

Adding, Removing, or Replacing an AC-Input Power Supply

Step 5 Release the bail latch that secures the source AC power cord to the AC receptacle on the power supply faceplate.

Step 6 Remove the power cord from the AC receptacle.

Step 7 Grasp the power supply carrying handle with one hand and pull the unit halfway out of the bay to disengage the blind-mating connector at the back of the power supply from the backplane.

Warning The AC-input power supply weighs 17 lb (7.73 kg). For safety, use both hands to withdraw the unit from the bay.

Step 8 Place your free hand beneath the power supply to support its weight and withdraw the unit completely from the bay.

Step 9 Pending further action, set the unit aside.

If you intend to return the removed power supply to the factory for repair or replacement, repackage the unit properly for return shipment using the original packing materials, if available.

Step 10 On the new AC-input power supply that you intend to install in the now vacant bay, set the rotary power switch on the new power supply to the standby (OFF) position.

Step 11 Grasp the carrying handle on the power supply with one hand; place your free hand beneath the unit to support its weight.

Step 12 Position the unit appropriately for insertion into the power supply bay.

Step 13 Gently slide the new power supply into the bay, carefully seating it so that the power supply faceplate is flush against the sheet metal of the power supply bay. Doing so ensures that the blind-mating connector at the rear of the power supply is firmly seated in the backplane connector.

Caution To prevent damage to the blind-mating connectors, do not use excessive speed or force when inserting the new power supply into the bay.
