Removing Components from the MX480 Router Before Installing It with a Lift
To make the router light enough to install with a lift, you must first remove most
componentsfrom the chassis. The procedures for removing components from the chassis
are for initial installation only, and assume that you have not connected power cables
to the router. The following procedures describe how to remove components from the
chassis, first from the rear and then from the front:
1.

Lift on page 189
2.

Removing the Power Supplies Before Installing the MX480 Router with a Lift
Remove the leftmost power supply first and then work your way to the right. To remove
the AC or DC power supplies for each power supply (see Figure 52 on page 190):
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, 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. Loosen the captive screws on the bottom edge of the power supply faceplate.
4. Pull the power supply straight out of the chassis.
