J4300 and J6300 Services Router PIM Installation Instructions

Tools and Parts Required

To replace a component, you need the following tools and parts:

Electrostatic bag or antistatic mat

Electrostatic discharge (ESD) grounding wrist strap

Phillips (+) screwdriver, number 2

Replacing a PIM

Physical Interface Modules (PIMs) in J4300 and J6300 Services Routers are field
replaceable. The router must be powered off before the PIMs are removed or
installed. This section contains the following topics:

“Installing a PIM” on page 3

The PIMs are installed in the front of the Services Router. A PIM
weighslessthan1lb(0.5kg).

To remove a PIM (see Figure 1):

1. Place an electrostatic bag or antistatic mat on a flat, stable surface to receive

the PIM.

2. 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 the J-series Services Router User Guide.

3. Press and release the power button to power off the router. Verify that the

POWER ON LED blinks and then turns off.

4. Label the cables connected to the PIM so that you can later reconnect each

cable to the correct PIM.

5. Disconnect the cables from the PIM.

6. If necessary, arrange the cables to prevent them from dislodging or developing

stress points:

2 Removing a PIM

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. Loosen the captive screws on each side of t he PIM faceplate.

8. Grasp the handles on each side of the PIM faceplate and slide the PIM out of

the router. Place it in the electrostatic bag or on the antistatic mat.

9. If you are not reinstalling a PIM into the emptied slot, install a blank PIM panel

over the slot to maintain proper airflow .

To install a PIM (see Figure 2):

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 the J-series Services Router User Guide.

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.

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