Removing Components from the MX240 Chassis Before Installing It Without a Lift
To make the router light enough to install manually, you first remove most
components from the chassis. The procedures in this section 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 MX240 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 (see Figure 1):
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. 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 DC 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. Pull the power supply straight out of the chassis.
