Reinstalling the Power Supplies After Installing the MX480 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, follow this procedure for each power supply (see
installation of the DC power supplies):
1. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other
end of the strap to the ESD point on the chassis.
2. On an AC-powered router, switch the AC input switch on each power supply to the off (O) position.
On a DC-powered router, Move the DC circuit breaker on each DC 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.
