The BRI power supply (SPEC-BNPWR1) is a power supply unit that is used to power BRI phones or other BRI devices connected to our BRI card. This is only for the BRI card in NT mode with TE devices connected to it. When the Sangoma card is in TE mode this device should not be used. 

The power supply unit is powered with a molex connector (from internal/external PSU), the output of the unit will be a connector that will plug into the green connector on the Sangoma card. See image below for the location and picture of the green connector. 

The beroNet Bridge (bfBridge) can be used to access all 4 RJ45 outputs of a berofix baseboard with only one bf4S0,bf4FXS,bf4FXO or bf2S02FXS plugged on the baseboard.
