4.2.3 BU Connections
This section describes the installation for the Base Units with the RF signal supplied from an MA
RIU Lite. If an RIU system is installed, refer to the RIU Installation and Configuration Guide for
detailed instructions on the RIU connections.
NOTE: It is assumed that the patch panel cabinet (SC/APC adaptors) for fiber optic cable connections is
installed in the rack near the BUs.
To connect the BU
1. Connect fiber jumper between splice tray and patch panel cabinet.
2. Connect fiber jumpers between the corresponding BU optical ports and the patch panel.

3. Connect the BU rear panel Uplink and Downlink ports to the corresponding ports on the

an RIU).
4. Connect the BU rear panel COM to the MA430 rear panel RS485 connector.
5. Connect the Power connection on the BU rear panel.
