Removing an AC or DC Power Tray from a Cisco ASR 9000 Series Router
The power trays are not a true FRU because they do not support OIR. However, if replacement is
necessary, follow these steps to remove and replace the power trays in a Cisco ASR 9000 Series Router.
Caution Power tray removal and replacement procedures are to be performed by qualified service persons only.
Caution All power to the node must be shut off at the branch circuit disconnect device before beginning power
tray replacement procedures. Removal of a tray requires disconnection of power cabling on the back of
the chassis that exposes service persons to exposed wiring from the unaffected tray.
Caution All terminal block covers should be replaced prior to energizing the power cabling to the system.
Follow these steps to remove an AC or DC power tray from the chassis:
Step1 Disconnect AC or DC power from the power tray rear panel.
Step2 Remove all power modules from the power tray.
Step3 For the CiscoASR 9010 Router, remove the front grill by pulling it away from the chassis (Figure5-12).

Step4 For the Cisco ASR 9922 Router, the front power tray bezel is a standard item that comes with ball studs
already installed. Simply install it by snapping it onto the chassis, or remove it by pulling it away from
the chassis (Figure5-13).
