2.3 Connectors

Each LAU model is equipped with one Main port connector and either
two or four port channel connectors. The Main port must be connected to
a lobe port on the MAU. The attaching device must be connected to the
LAU port channel connectors.
The type of connector (RJ45 or data connector) installed on your LAU
depends on the particular Andrew LAU model that you purchased.

RJ11 male connectors may be used instead of RJ45 male connectors on
the twisted pair cables used in the network. Both types will work in the
female connectors on the LAUs. Whether RJ45 or RJ11 male connectors
are used, the transmit and receive pins are always the four center pins in
the connector as shown in the illustration above..
