Installing a PIM

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

Caution: Do not install a combination of PIMs in a single chassis that exceeds the maximum power and heat capacity of the chassis. If J-series power management is enabled, PIMs that exceed the maximum power and heat capacity remain offline when the chassis is powered on.

To verify that the combination of PIMs to be installed in a chassis do not exceed the power and heat capacities for the J4350 or J6350 router, see Planning for Power Management.

To install a PIM (see Figure 74):

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.

   Caution: 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.
