Figure 4: Removing a DPC
Removing the FPCs Before Installing the MX480 Router Without a Lift
To remove an FPC (see Figure 5):
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.
