Removing the DPCs Before Installing the MX480 Router with a Lift
To remove a DPC (see Figure 51 on page 182 ):
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.
