NOTE
l The Extender can be used to lengthen the distance between the RHUB3908 and the pRRU3901
connected using the Ethernet cable. If the Extender is used, the Ethernet cable is divided into two parts,
one between the RHUB3908 and the Extender and the other between the Extender and the pRRU3901.
l The Ethernet cable used for connecting the GE port on the pRRU3901 to the AC transmission port is
required only when the pRRU3901 have three transmission ports and is configured with the Wi-Fi
daughter board.
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.
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) pRRU3901 RF Jumper of the
LampSite Hardware Description.
