Removing a PIM
The PIMs are installed in the front of the Services Router. A PIM weighs less than 1 lb (0.5 kg).
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
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:
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.
