Before installing the pRRU3901 cables, you must be aware of the following information:
The pRRU3901 can obtain power supply through the power over Ethernet (PoE).
For external antennas corresponding to RF daughter board 1, the TX port and RX port
are ANT0 and ANT1, respectively. For external antennas corresponding to RF daughter
board 2, the TX port and RX port are ANT2 and ANT3, respectively. For external
antennas corresponding to RF daughter board 3, the TX port and RX port are ANT4 and
ANT5, respectively.
are ANT0 and ANT1, respectively. For external antennas corresponding to RF daughter
board 2, the TX port and RX port are ANT2 and ANT3, respectively. For external
antennas corresponding to RF daughter board 3, the TX port and RX port are ANT4 and
ANT5, respectively.
The external antenna system is optional, and the pRRU3901 jumpers are not delivered.
By default, the pRRU3901s are configured with built-in antennas. If the external antenna
system is connected, the antenna system automatically switches to the external one. One
end of the pRRU3901 RF jumper is the SMA male connector, which is connected to the
external antenna TX/RX RF port on the pRRU3901. The other end of the pRRU3901 RF
jumper is the type N male connector, which is connected to the antenna system. For the
standard of the pRRU3901 RF jumper, see (Optional) RF Jumper of the DBS3900
