7 Module status
The status of the module can be monitored in two ways.
Gyda-SC (system controller).
LED's at the front of the sub-rack.
The LED's are mounted on the module itself, whereas the Gyda-SC is a separate module
giving detailed information of the status of the card. The functions of the LED's are described
in sections 7.1. The Gyda-SC is described in a separate user manual.
