Removing a PIC

To remove a PIC, follow this procedure (see Figure 60):

1. Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the PIC. If the PIC connects to fiber-optic cable, have ready a rubber safety cap for each transceiver and cable.
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. Verify that the router is attached to a proper earth ground. For more information about ESD, see Preventing Electrostatic Discharge Damage.
3. Follow the instructions in Removing an FPC to remove the PIC's host FPC from the chassis. Lay the FPC component side down on an antistatic foam mat on a flat, stable surface. If a foam mat is not available, substitute a standard flat antistatic mat but use extra care when laying the FPC on it to avoid damaging the electrical components on the FPC and PICs.
4. With the FPC lying component side down, use a Phillips screwdriver to loosen the two screws that secure the PIC to the FPC.
5. Carefully turn over the FPC and lay it on the mat component side up and with the PIC faceplates facing you.
6. Pull the PIC straight out of the FPC slot.

   Caution: You might need to rock the PIC back and forth to loosen it from the connector in the FPC slot. To avoid bending the pins on the connector, use the smallest and gentlest motion possible.

7. Place the PIC in the electrostatic bag or on the antistatic mat.
8. If you are not reinstalling a PIC into the emptied slot, install a blank PIC panel over the slot before reinstalling the FPC, to maintain proper airflow in the FPC card cage.
