Reinstalling the Power Supplies After Installing the MX240 Router without a Lift
Reinstall the rightmost power supply first and then work your way to the left. To reinstall the AC or DC
power supplies (see Figure 66 on page
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.
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 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. 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.
