Troubleshooting the RAD Devices
If a RAD is functioning properly and communicating with the Mongoose, all four of its status indicators
(Power, Comm, Audio Rx, and Audio Tx) will be green. e following table details possible causes
and solutions if one or more of these indicators are off or red. If you detect a problem with a RAD, we
recommend first checking the Mongoose to determine if the problem is originating there.
Note: It is best to check these indicators in the following order: Power, Comm, Audio Rx, and Audio
Tx. If the power isn’t working, nothing else will work. If the data communications (Comm) isn’t working,
Audio Tx will not work. If Audio Rx isn’t working, Audio Tx will not work.

Room is dark and LEDs are off. Shine a light on the RAD front panel.
The Mongoose is not powered. Power on the Mongoose.
A miswired or broken cable is
disrupting power to the RAD.
Use a cable tester to verify CAT 5 termination.
If using a punch block, verify that the brown
pair is properly punched. (Assuming T568B
termination).
The cable is not plugged into a
Mongoose.
Plugging the RAD cable into some other device
(like an Ethernet switch) will not supply power
to the RAD.
