Installing a PIM

Do not hot-swap PIMs. Failure to power off the router before removing or installing a PIM might result in damage to the hardware.

To install a PIM (see Figure 40):

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to the ESD point on the chassis, or to an outside ESD point if the Services Router is disconnected from earth ground. For more information about ESD, see Preventing Electrostatic Discharge Damage.
2. Press and release the power button to power off the router. Verify that the POWER LED blinks and then turns off.
3. Align the notches in the connector at the rear of the PIM with the notches in the PIM slot in the Services Router, and slide the PIM in until it lodges firmly in the router.

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

4. Tighten the captive screws on each side of the PIM faceplate.
5. Insert the appropriate cables into the cable connectors on the PIM.
6. If necessary, arrange the cables to prevent them from dislodging or developing stress points:
   • Secure each 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.
   • Use fasteners to maintain the shape of cable loops.
7. Press and release the power button to power on the router. Verify that the POWER LED lights steadily after you press the power button.
8. Verify that the PIM LEDs light steadily green to confirm that the PIM and its ports are online and operational. For more information about PIM LEDs, see Field-Replaceable PIMs.

   You can also verify correct PIM functioning by issuing the show chassis fpc pic-status command described in the JUNOS System Basics and Services Command Reference.

   In the show chassis fpc pic-status command, the PIM slot number is reported as an FPC number and the PIM number (always 0) is reported as a PIC number.
