Caution The DC return connection to this system is to remain isolated from the system frame and chassis (DC-I).

Step 1 On the front of the router, turn the power switch to the standby () position.

Step 2 Switch the circuit breaker to the off position, and tape the switch handle to the off position. Step 3 Pull the terminal block plug from the terminal block.

Step 4 Locate the DC power supply grounding stud.

Step 5 Remove the nut, ground lug, star washer, ground lug, and star washer and save for reuse on the new DC power supply.

Step 6 Move the power up restrictor to the left to gain access to the upper power supply captive installation screw.

Step 7 Use a Number 2 Phillips screwdriver to unscrew the upper power supply captive installation screw. Step 8 Unscrew the lower power supply captive installation screw on the lower left of the power supply. Step 9 Grasping the captive installation screws, pull the power supply from the chassis.

This complete the procedure for removing the DC power supply.
