Installing a PIM

To install a PIM (see Figure 31):

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 ON 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 then 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 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.
   • 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 ON 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 J2300 Physical Interface Module (PIM) or J4300 and J6300 Physical Interface Modules (PIMs).

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