Function
Indicates that the optical link between Base Unit and Remote Hub Unit are not functioning
LED Specifications
Base Unit LEDs
The Base Unit has three types of LEDs. One type indicates the power status. One type indicates that the lasers are functioning. One type indicates the status of link
operations between the Base Unit and the RHU-one LED for every RHU. All LEDs should be on when the unit is in operation.
