power supplies (see Figure 60 on page
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. For an AC-powered router, switch the AC input switch on the power supply to the off (O) position. For
a DC-powered router, switch the DC circuit breaker on the power supply to the off (O) position.
We recommend this even though the power supplies are not connected to power sources.
3. Pull the power supply straight out of the chassis.
