RJ-45 Port
There is one RJ-45 port on a single band RAU and two RJ-45 ports on the
900/1800 MHz and the 1800/1800 MHz dual band RAUs.
Figure 5-2 RJ-45 Port on a Single Band RAU
Figure 5-3 RJ-45 Ports on a Dual Band RAU
On a 900/1800 dual band RAU, the top RJ-45 port is for the 900 MHz band and the
bottom port is for the 1800 MHz band. The signals are combined and passed to a sin-
gle SMA connector.
On an 1800/1800 dual band RAU, the ports are interchangeable. It does not matter
which Cat-5 cable coming from the 1800/1800 dual band Expansion Hub you plug
into the top or the bottom. However, you may want to plug the top 1800 MHz Expan-
sion Hub’s Cat-5 cable into the top port and the bottom Expansion Hub’s cable into
the port for easier troubleshooting later.
