Removing Components from the MX480 Chassis 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:
1. Removing the Power Supplies Before Installing the MX480 Router Without a
Lift on page 1

Lift on page 2

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 1):
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. 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.
