This section describes the cable connections for a single pRRU and multiple pRRUs.
Before installing the pRRU cables, you must be aware of the following information:

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 When two Ethernet cables are used to transmit CPRI signals, connect one end of the cables to the
CPRI_E0 and CPRI_E1 ports on the pRRU panel and the other end to any two ports of CPRI_E0 to
CPRI_E7 on the RHUB panel. This document describes signal transmission using one Ethernet cable
as an example.

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
