8.2.1 Connectors
Antenna/Duplexer ports (2x N connectors)
The radio unit is a 2x2 MIMO unit with internal duplexers. This means each N connector is both a transmit and a receive
port. In order to aid in diagnostics, the left port should be connected to the vertical antenna polarisation while the right port is
connected to the horizontal polarisation.
Be careful that feeders connected to the N connectors are not over tightened.
Ethernet
Two shielded RJ45 sockets provide the Ethernet connection(s). Shielded cable is not normally required.
Serial
Two shielded RJ45 sockets provide serial port connection.
Power connector
A Phoenix Contact MSTB 2, 5 HC connector provides the Power Connection.
GPIO
A JST S12B-EH connector has the GPIO, Alarm and Reference connections.
Earth
A chassis earth point is provided.
USB host (USB-M)
An A-type USB connector provides the connection to the USB host port (software support will be developed in the future).
USB device (USB-S)
A mini B type USB connector provides the connection to the USB device port (software support in future).
8.2.2 LED Behaviour
Power LED (Green)
The power LED is located on the right of the front panel. The LED lights up when power is applied.
Link LED (Green)
NDL: The Link LED lights up when an RF link is active.
RRU: The Link LED has four different modes of operation each indicating a different RF link state. It is off when the RRU is
not detecting a signal from the BRU. It will flash with a 50 percent duty cycle at 1 Hz when the radio is synchronised with the
BRU. A pattern of two flashes followed by a gap will repeat at 1 Hz once a downlink is established. And finally, it will be
constantly on once a full duplex link is established.
BRU: The Link LED operates with a time out of approximately two minutes. Every time communication occurs between the
BRU and one of its RRUs the timer will reset. Regular communication between the units will be indicated by this LED remaining
on.
Alarm LED (Red)
During boot up (proximally 10 seconds after power is applied) the LED will flash at a rate of 1Hz to indicate that the radio is in
its boot up process.
Once boot up is complete, the LED will flash when the radio is in an Alarm state.
Ethernet LEDs
Each Ethernet port has a green and an orange LED. The green LED flashes when the port is receiving data. The orange LED
is off when the port is 10 Mbit/s and on when it is 100 Mbit/s.
