Removing Components from the MX480 Router Before Installing It Without a Lift
If you cannot use a mechanical lift to install the router (the preferred method), you can
install it manually. To make the router light enough to install manually, you first remove
most components from 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:

Removing the Power Supplies Before Installing the MX480 Router Without 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 63 on page 203):
1. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points 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. Loosen the captive screws on the bottom edge of the power supply faceplate.
4. Pull the power supply straight out of the chassis.
