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.
3.3.1 Power LED—Right
LED
Color
Description
Dull Red
Initial power-up. Power present on Hub allowing Module detection to
proceed; or
Module NOT Enabled through System Setup; or
Module not inserted in valid Hub slot.
Green
Module in normal operation. Ready for use (Power to module).
Off
No power to module.
3.3.2 Communications—Middle
Once plugged in, the Optical or Transport Module attempts to establish communication with the far end.
Service Modules do not communicate with Remote Units or other Hubs; therefore, the Communications
LED is deactivated for Service Modules.
