PICs for the M7i and M10i Routers

This section describes how to install or replace a PIC on the M7i and M10i routers. The PICs on M7i and M10i routers are installed directly into FPCs that are built in to the chassis. (These FPCs cannot be removed from the chassis.)

On the M7i routers, the PICs are arranged in one row of four slots labeled 0/3, 0/2, 0/1, and 0/0 from left to right.

On the M10i routers, the PICs are arranged in two rows of four slots. The slots in the upper row are labeled 0/3, 0/2, 0/1, and 0/0, and the slots in the lower row are labeled 1/3, 1/2, 1/1, and 1/0 from left to right.

The PICs are hot-insertable and hot-removable, so you can remove and replace them without powering off the router. When you remove a PIC, forwarding halts briefly, then resumes. The PIC itself no longer receives or transmits data.

Removing a PIC from an M7i or M10i Router

To remove a PIC from an M7i or M10i router, follow this procedure (see Figure 1):

  1. Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the PIC. If the PIC uses fiber-optic cable, have ready a rubber safety cap for each transceiver and cable.
  2. Attach an ESD wrist strap to your bare wrist and connect the wrist strap to one of the ESD points on the chassis.
  3. If the PIC has multiple ports, label the cable connected to each port so that you can reconnect the cables correctly.
  4. Take the PIC offline by using one of the following methods:
  5. 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. Arrange the disconnected cables in the cable management system.
  6. Pull the right end of the PIC ejector lever away from the PIC faceplate. This disconnects the PIC from the midplane.
  7. Grasp both sides of the PIC and slide it out of the chassis. Do not use the ejector lever as a handle. Place the PIC in the electrostatic bag or on the antistatic mat that you prepared in Step Step 1.

Installing a PIC in an M7i or M10i Router

To install a PIC in an M7i or M10i router, follow this procedure (see Figure 2):

  1. Attach an ESD strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
  2. Pull the ejector lever away from the PIC faceplate and hold it out while you insert the PIC.
  3. Align the rear of the PIC with the guides located at the bottom corners of the PIC slot.
  4. Slide the PIC into the card cage until about 0.5 in. (1 cm) of the PIC remains outside the slot and you feel some resistance. Release the ejector lever.   

    Be careful to insert the PIC straight into the slot to avoid damaging the components on the PIC.

  5. Continue pushing the PIC until it contacts the midplane and you hear a click. The ejector lever engages and closes automatically.
  6. If the PIC uses fiber-optic cable, remove the rubber safety cap from each transceiver and the end of each cable.
  7. Insert the appropriate cables into the ports on the PIC and arrange the cables in the cable management system.
  8. Bring the PIC online by using one of the following methods:

When a PIC is functioning normally, its status LED lights green. Some PICs have a single status LED and others have one LED per port. For more information, see the M7i PIC Guide, and the M10i PIC Guide.

You can also use the following CLI command to confirm correct PIC functioning:

user@host> show chassis fpc pic-status fpc-slot

For a PIC to function, you must add the necessary statements for it to the router configuration. For instructions, see the JUNOS Network Interfaces and Class of Service Configuration Guide.
