44 Replacing a Physical Interface Module
Replacing a Physical Interface Module
The SSG 140 device has four slots in the back panel for WAN PIMs. SSG 140 PIMs
are field installable and replaceable. The SSG 140 device must be powered off
before PIMs are removed or installed.
Removing a Blank Faceplate
To maintain proper airflow through the device, blank faceplates should remain over
slots that do not contain PIMs. Do not remove blank faceplates unless you are
installing a PIM in the empty slot.
To remove a blank faceplate, perform the following steps:
1. 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 device is
disconnected from earth ground.
2. Switch off the power switch on the back of the device. Verify that the POWER
LED turns off.
3. Loosen and remove the screws on each side of the faceplate using a number-2
phillips screwdriver.
4. Remove the faceplate.
Removing a Physical Interface Module
The PIMs are installed in the back panel of the SSG 140 device. A PIM weighs less
than 1 pound (0.5 kilogram).
To remove a PIM, perform the following steps:
1. Place an electrostatic bag or antistatic mat on a flat, stable surface on which
you intend to place the PIM.
2. Attach an ESD grounding strap to your bare wrist, and connect the strap to an
ESD point.
3. Power off the device. Verify that the POWER LED 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.
WARNING: Make sure the power is off to the device when removing PIMs. PIMs
are not hot-swappable.
