Removing an M10i PIC

To remove a PIC (see Figure 1):

1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
2. If the PIC connects to fiber-optic cable, have ready a rubber safety cap for each transceiver and cable.
3. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
4. If the PIC has multiple cable connector ports, label the cable connected to each port, to make it easier to reconnect the cables correctly.
5. Use one of the following methods to take the PIC offline:
   • Press and hold the PIC offline button until its failure indicator LED lights, which usually takes about 5 seconds. The failure LED is usually red; for more information, see the M10i Multiservice Edge Router PIC Guide. The offline button for each PIC is located on the HCM and is labeled with the PIC slot number. The PICs in FPC 0 are located on the upper HCM, and the PICs installed in FPC 1 are located on the lower HCM.
   • Issue the following CLI command:
     
     

     user@host> request chassis pic fpc-slot fpc-slot pic-slot pic-slot offline

     For more information about the command, see the Junos System Basics and Services Command Reference.

6. Disconnect the cables from the PIC. If the PIC uses fiber-optic cable, immediately cover each transceiver and the end of each cable with a rubber safety cap.

   Warning: Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable connected to a transceiver emit laser light that can damage your eyes.

   Caution: 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. Arrange the cable in the cable management system to prevent it 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.

   Caution: 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.

   Caution: 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.

8. Unseat the PIC from the chassis:
   • For a regular PIC, pull the right end of the PIC ejector lever away from the PIC faceplate.
   • For a quad-wide PIC, pull the end of each ejector lever away from the PIC faceplate, toward the outer edges of the PIC.
9. Grasp both sides of the PIC faceplate and slide it out of the chassis. Do not use the ejector lever as a handle.
10. Place the PIC in the electrostatic bag or on the antistatic mat.
11. If you are not reinstalling a PIC into the emptied slot within a short time, install a blank PIC panel over the slot to maintain proper airflow in the chassis.
