Chapter 3 Installing the Cisco ASR 903 Router
Connecting the Cisco ASR 903 Router to the Network
Step 1 Disconnect the power cord from the power source. Do not touch the metal prongs on the power cord
when it is still connected to the power supply.
Step 2 Remove the power cord from the power connection on the power supply. Do not touch the metal prongs
embedded in the power supply.
Step 3 Loosen the captive installation screws.
Step 4 Grasp the AC power supply with one hand, and slide it part of the way out of the chassis. Place your
other hand underneath the power supply, and slide it completely out of the chassis.
Step 5 If the power supply bay is to remain empty, install a blank filler plate (Cisco part number
A900-PWR-BLANK) over the opening, and secure it with the captive installation screws.
