NOTE
l The Extender can be used to lengthen the distance between the RHUB and the pRRU connected using
the Ethernet cable. If the Extender is used, the Ethernet cable is divided into two parts, one between
the RHUB and the Extender and the other between the Extender and the pRRU.
l The Ethernet cable used for connecting the GE port on the pRRU to the AC transmission port is required
only when the pRRU have three transmission ports and is configured with the Wi-Fi daughter board.
The pRRU can obtain power supply through the power over Ethernet (PoE) or AC/DC
power adapter. You are suggested to use AC/DC power adapter.
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 pRRU jumpers are not delivered. By
default, the pRRUs 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
pRRU RF jumper is the SMA male connector, which is connected to the external antenna
TX/RX RF port on the pRRU. The other end of the pRRU RF jumper is the type N male
connector, which is connected to the antenna system. For the standard of the pRRU RF
jumper, see pRRU RF Jumper of the LampSite Hardware Description.
