Replacing Cisco ASR 9000 Series Router Components

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:

Procedure

Step 1

Disconnect AC or DC power from the power tray rear panel.

Step 2

Remove all power modules from the power tray.

Step 3

For the Cisco ASR 9010 Router, remove the front grill by pulling it away from the chassis (see figure below).

Step 4

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 (see figure below).
