Replacing a Physical Interface Module
Removing a Blank Faceplate
To maintain proper airflow through the SSG device, blank faceplates should remain
over slots that do not contain mini PIMs. Do not remove a blank faceplate unless
you are installing a mini PIM in its empty slot.
To remove a blank faceplate, do the following:
1. Place an electrostatic bag or antistatic mat on a flat, stable surface to place the
mini PIM.
2. Attach an 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 SSG device is
disconnected from earth ground.
3. Unplug the power adapter from the device. Verify that the POWER LED is off.
4. Loosen and remove the screws on each side of the faceplate using a 1/8’ slotted
screwdriver.
5. Remove the faceplate, then place the faceplate in the electrostatic bag or on the
antistatic mat.
Removing a Mini PIM
Mini PIMs are installed in the front panel of the SSG device. A mini PIM weighs less
than .2 lb. (106g).
To remove a mini PIM, do the following:
1. Place an electrostatic bag or antistatic mat on a flat, stable surface to place the
mini PIM.
2. Attach an 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 SSG device is
disconnected from earth ground.
3. Unplug the power adapter from the device. Verify that the POWER LED is off.
4. Label the cables connected to the mini PIM so that you can later reconnect each
cable to the correct mini PIM.
5. Disconnect the cables from the mini PIM.
6. If necessary, arrange the cables to prevent them from dislodging or developing
stress points:
a. Secure the cables so that it they are not supporting their own weight as
they hang to the floor.
b. Place any excess cables out of the way in neatly coiled loops.
c. Use fasteners to maintain the shape of the cable loops.
7. Loosen and remove the screws on each side of the mini PIM faceplate using a
1/8” slotted screwdriver.
