Replacing an M10i PIC

Up to eight regular PICs install into an M10i router, as shown in M10i Chassis Description. Quad-wide PICs occupy all four slots in an FPC row.

PICs are hot-removable and hot-insertable. A removed PIC no longer receives or transmits data, and removing or inserting a PIC briefly interrupts forwarding of traffic through the remaining PICs.

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 OS 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.

To install a PIC (see Figure 2):

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.
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.

   Caution: 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.

   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. 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.

   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.

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 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 online

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

   The normal functioning status 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 Maintaining the M10i PICs and PIC Cables.
