Each module has a large red LOCAL FAULT LED and a large green MODULE OK LED at the top of the
card edge. This green LED indicates good module health while the red LED indicates that there is a fault
condition on the module. Each module has its own criteria that determines when the red fault LED comes
on. When the red LOCAL FAULT LED is On the module can also assert a fault condition on the Frame
Status bus. On each module there is a jumper that disables sending local card fault information to the
Frame Status Bus. For more information about fault conditions on individual modules, and for the location
of the Frame Status Jumper on the module consult the individual chapter for the module. For example, if
a module requires video or audio for its functionality and the video or audio is not present, the red LOCAL
FAULT LED on the module will be On and the fault will be reported on the frame status bus if the FRAME
STATUS jumper on the module is set to the On position (default).

INSTALLING THE MODULE REAR PLATES

Each module is shipped with a matching rear panel plate which houses the connectors appropriate for the
module. When installing a rear plate, locate the desired slot position where you wish to install the rear
plate. Make a note of the slot number where you are installing the rear plate. Orient the plate so that the
labeling is visible when the plate is installed. Loosely fasten the plate to the extrusions using the mounting
screws provided, beginning with the top screw. You will tighten the screws after the main module is
installed.
