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.

Figure 51: Removing a DPC

Removing the FPCs Before Installing the MX480 Router Without a Lift

To remove an FPC (see Figure 52 on page 88):

1. Have ready an antistatic mat for the FPC. Also have ready rubber safety caps for each

PIC using an optical interface on the PIC that you are removing.

2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect

the strap to one of the ESD points on the chassis.

3. Simultaneously turn both the ejector handles counterclockwise to unseat the FPC.

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

5. Place one hand around the front of the FPC and the other hand under it to support it.

Slide the FPC completely out of the chassis, and place it on the antistatic mat or in

the electrostatic bag.

CAUTION: The weight of the FPC is concentrated in the back end. Be

prepared to accept the full weight—up to 18 lb (8.2 kg)—as you slide the

FPC out of the chassis.

When the FPC is out of the chassis, do not hold it by the ejector handles,

bus bars, or edge connectors. They cannot support its weight.
