3.3 Service, Optical and Transport Module LEDs

There are three LEDs on the front of each module which indicate operational status.
•
The right LED indicates power status.
•
The middle LED indicates communication status between the module and the far end.
•
The left LED indicates the current state of the module.
As part of the auto discovery process the Hub communicates with each module in turn, and cycles
through the installed modules. During this period, the Primary Hub checks for the presence of any
Secondary Hubs and Remote Units.
For Optical Modules, if no Remote Units are connected, only the right and middle LEDs are operational.
Initially the right LED will be a dull red, indicating that power is connected but the module is disabled.
This will change to green when the Hub has detected the presence of the module and initialized it. If
the module is disabled (in the Configuration GUI) the right LED will display red. The middle LED shows
green if the unit has successfully discovered one or more downstream system elements connected to
the Optical Module. Only when a Remote Unit is detected will the third LED be activated.
A fully functioning Optical module with operational downstream elements displays three green LEDs.
