CAUTION:

Do not stack hardware components on one another after you remove

them. Place each component on an antistatic mat resting on a stable, flat surface.

6.

Repeat the procedure for the second SCB.

Figure 3: Removing an SCB

Removing the DPCs Before Installing the MX240 Router Without a Lift

To remove a DPC (see Figure 4):

1.

Have ready an antistatic mat for the DPC. Also have ready rubber safety caps
for each DPC using an optical interface on the DPC that you are removing.

2.

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.

3.

Simultaneously turn both the ejector handles counterclockwise to unseat the
DPC.

4.

Grasp the handles, and slide the DPC straight out of the card cage halfway.

5.

Place one hand around the front of the DPC and the other hand under it to
support it. Slide the DPC completely out of the chassis, and place it on the
antistatic mat or in the electrostatic bag.

CAUTION:

The weight of the DPC is concentrated in the back end. Be prepared to

accept the full weight—up to 13.1 lb (5.9 kg)—as you slide the DPC out of the chassis.

When the DPC is out of the chassis, do not hold it by the ejector handles, bus bars,
or edge connectors. They cannot support its weight.

Do not stack DPC on top of one another after removal. Place each one individually
in an electrostatic bag or on its own antistatic mat on a flat, stable surface.
