Module status
The status of the module can be monitored in three ways.
1. 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.
6.1 GPI ALARM
– Module Status Outputs
These outputs can be used for wiring up alarms for third party control systems. The GPI
outputs are open collector outputs, sinking to ground when an alarm is triggered. The GPI
connector is shown in figures below.
Electrical Maximums for GPI outputs
Max current: 100mA
Max voltage: 30V
Be careful when connecting cables to the backplane of ETH1000-SW-10G, as
the GPI connecter has 5V output. Do not connect the GPI to an Ethernet port on
another unit, as this will damage the unit.
