Connector
Description
GPS
Connects to an external (optional) GPS antenna. The GPS antenna is ordered
separately. Connector Type: ITT CANNON APD DIN 72585
ETH1
Primary Fast Ethernet connector. Used for initial setup (and standalone tests),
and for connection to the backhaul network (in normal installations).
Connector Type: RJ-45 TYCO part no 1546907-1
ETH2
Second Ethernet port for local and out-of-band management.
In future versions, you will be able to daisy-chain this port to ETH1 in an
adjacent Base Station (located in the same BS site) in order to allow a single
Ethernet connection to the Backhaul.
ETH2 port can also function as a serial port (connection through the cable
supplied in the kit). This function is useful if the unit is not accessible via an IP
address connection.
PPS
PPS In and PPS Out can be used for synchronization of multiple
sectors, where the PPS Out of one sector is connected to the PPS
In of the next BS (daisy chained). This is relevant only for adjacent
sectors at the same BS site. See
Figure 3 GPS Antenna to Bracket Connections
Multi-sector Daisy-chained GPS Antennas section 0.
Connector Type: SMA sealed Industrial
48VDC
Power connector. External DC power connector (48VDC) for outdoor
deployment. Connector Type: RJ-45
GND
Ground blind hole connector. In normal installations, connect to the pole on
which the unit is mounted. (The BS unit does not include a lightning arrester.)
1.2.2 BS RF Antenna Interfaces
 RNU4000BS supports either four external or four internal antennas. The unit below
shows a model supporting four external antennas.
