Rectifier Shelf
The Rectifier Shelf, shown in
modules and a Low Voltage Disconnect (LVD) unit. The shelf interconnects the rectifier
modules and LVD unit, and provides an interface to external connectors.
Typically, the rectifier shelf contains two rectifier modules. The center panel on the shelf can be
removed to add a third rectifier, providing N+ redundancy as more equipment is added to the
RAN chassis.

Rectifier Module
The rectifier module converts 240 VAC prime power into -48 VDC for use within the RAN.
Each rectifier has four LEDs, shown in
controlled by the LVD unit under command of the STF2 module.

FUNCTIONAL DESCRIPTION
SMA connectors Diversity Out. 6 diversity outputs (bands A-F); each output being
used connects on one RDC module, in either same RAN or extension
RAN if present. Connection is made using cable 1955000P081
