Module status

The status of the module can be monitored in three ways.

1. Multicon Gyda System Controller (optional).

2. GPI at the rear of the sub-rack.

3. LED’s at the front of the sub-rack.

Of these three, the GPI and

the LED’s are mounted on the module itself, whereas the GYDA

System Controller is a separate module giving detailed information on the card status.
