Installing a PIC

To install a PIC, follow this procedure (see Figure 61):

1. 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.
2. If the PIC uses fiber-optic cable, verify that there is a rubber safety cap over each transceiver on the faceplate. Install a cap if necessary.
3. Place the FPC into which you are installing the PIC on an antistatic foam mat, component side up and with its faceplate facing you. 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. Push the PIC part way into the FPC slot. Carefully align the tabs on the back of the PIC with the notches in the connector at the rear of the FPC slot. Push the PIC in until the connectors join.

   Caution: Be careful to insert the PIC straight into the FPC slot. If the pins on the FPC connector are not aligned properly with the holes in the PIC connector, the pins might be bent or the holes damaged. Either kind of damage can prevent the PIC and FPC from functioning correctly.

5. Carefully turn over the FPC and lay it component side down on the mat with the PIC faceplates facing you.
6. Using a Phillips screwdriver, tighten the two screws that secure the PIC in the FPC.
