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 39: Removing a DPC
Removing the FPCs Before Installing the MX480 Router with a Lift
To remove an FPC (see
):
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 an approved site ESD grounding point. See the instructions for your site.
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.
