ESD grounding strap
To remove an AC power supply (see
1. Switch off the dedicated customer site circuit breaker for the power supply, and remove the power
cord from the AC power source. If the services gateway is equipped with high-capacity AC power
supplies, remove both of the power cords for the power supply. Follow the ESD and disconnection
instructions for your site.
2. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on
the chassis.
3. Move the AC input switch on the chassis above the AC power supply to the off (O) position. If the
services gateway is equipped with high-capacity AC power supplies you must also move the AC input
switch on the power supply itself to the off (O) position.
4. While grasping the handle on the power supply faceplate with one hand, use your other hand to pull
the spring-loaded locking pin in the release lever away from the chassis and turn the release lever
counterclockwise until it stops.
5. Let go of the locking pin in the release lever. Ensure that the pin is seated inside the corresponding
hole in the chassis.
6. Pull the power supply straight out of the chassis. The power supply can weigh up to 12 lb (5.5 kg). Be
prepared to accept its full weight.
