1.Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis. For more information about ESD, see “Preventing Electrostatic Discharge Damage” on page 130.

2.For an AC-powered router, switch the AC switch on the power supply slot to the off position (O). For a DC-powered router, switch the circuit breaker on the power supply to the OFF position.

We recommend this even though the power supplies are not connected to power sources.

3.Using both hands, slide the power supply straight into the chassis until the power supply is fully seated in the chassis slot. The power supply faceplate should be flush with any adjacent power supply faceplate or blank installed in the power supply slot.

4.Tighten the captive screws.
