Removing Components from the MX240 Chassis Before Installing It Without a Lift

Removing the Power Supplies Before Installing the MX240 Router 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:

1. Removing the Power Supplies Before Installing the MX240 Router Without a

Lift on page 1

2. Removing the Fan Tray Before Installing the MX240 Router Without a

Lift on page 2

3. Removing the SCBs Before Installing the MX240 Router Without a Lift on page 2

4. Removing the DPCs Before Installing the MX240 Router Without a Lift on page 3

5. Removing the FPC Before Installing the MX240 Router Without a Lift on page 4

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):

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.

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.

Pull the power supply straight out of the chassis.
