universal power supplies (see
1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to
an approved site ESD grounding point. See the instructions for your site.
2. On an AC-powered router, move the AC input switch in the chassis above each power supply to the
off (O) position. On a DC-powered router, move the DC circuit breaker on each power supply faceplate
to the off (O) position.
We recommend this even though the power supplies are not connected to power sources.
3. 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.
4. Let go of the locking pin in the release lever. Ensure that the pin is seated inside the corresponding
hole in the chassis.
5. Pull the power supply straight out of the chassis.
