Install a PIC

To install a PIC, follow this procedure (see Figure 31):

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. For more information about ESD, see Prevent 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. Prepare the PIC for insertion into the chassis:
   • For a regular PIC, hold the PIC in one hand and with your other hand pull the end of the ejector lever away from the PIC faceplate. Hold the lever out while you insert the PIC.
   • For a quad-wide PIC, verify that the end of each ejector lever is pulled away from the PIC faceplate, toward the ends of the PIC.
4. Align the rear of the PIC with the guides located at the bottom corners of the PIC slot.
5. Slide the PIC into the slot:
   • For a regular PIC, slide the PIC into the slot until about 0.5 in. (1 cm) of the PIC remains outside the slot and you feel some resistance. Release the ejector lever and gently push the PIC faceplate until you hear a click as the PIC contacts the midplane. The ejector lever engages and closes automatically.
   • For a quad-wide PIC, slide the PIC into the slot until it contacts the midplane. Push the ejector levers inward toward the PIC faceplate to seat the PIC securely in the chassis.

   Slide the PIC straight into the slot to avoid damaging the components on the PIC.

6. If the PIC uses fiber-optic cable, remove the rubber safety cap from each transceiver and the end of each cable.

   Do not look directly into the ends of fiber-optic cables or into the transceivers on the interface faceplate. Single-mode fiber-optic cable and the interfaces that use it (such as ATM and SONET/SDH interfaces) emit laser light that can damage your eyes.

   Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.

7. Insert the appropriate cables into the cable connectors on the PIC.
8. Arrange each cable in the cable management system to prevent the cable from dislodging or developing stress points. Secure the cable so that it is not supporting its own weight as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop in the cable management system. Placing fasteners on the loop helps to maintain its shape.

   Do not let fiber-optic cable hang free from the connector. Do not allow fastened loops of cable to dangle, which stresses the cable at the fastening point.

   Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

9. Use one of the following methods to bring the PIC online:
   • Press and hold the PIC offline button until the status LED on the PIC faceplate indicates normal functioning, which usually takes about 5 seconds. The LED is usually green; for more information, see the M5 and M10 Internet Routers PIC Guide. The offline button for each PIC is located below it on the craft interface and is labeled with the PIC slot number.
   • Issue the following CLI command:
     user@host>request chassis pic fpc-slot fpc-slot pic-slot pic-slot online

     For more information about the command, see the JUNOS Internet Software Operational Mode Command Reference: Protocols, Class of Service, Chassis, and Management.

   The normal functioning indicator LED confirms that the PIC is online. You can also verify correct PIC functioning by issuing the show chassis fpc pic-status command described in Maintain PICs and PIC Cables.
