D OUT

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

1.8Rectifier Shelf

The Rectifier Shelf, shown in Figure 18, is a chassis/backplane device that contains rectifier 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.

Figure 18. Rectifier Shelf

1.8.1Rectifier Module

The rectifier module converts 240 VAC prime power into -48 VDC for use within the RAN. Each rectifier has four LEDs, shown in Figure 18 and described in Table 12. The rectifiers are controlled by the LVD unit under command of the STF2 module.
