number and if there are corresponding RFFE and RFBE board configuration files from a previous module or

saved configuration, the inserted modules configuration will be updated by the CSC accordingly.

A label bearing the respective module’s model number, version and serial number identifies each module. This

label is adhered to the side of the module and is not visible without removing the module from the slot.

A user definable removable yellow plastic labelling system has been provided on the external surface of the

BPFM bolted to the RFFE and RFBE modules to assist the user to identify allocated ports once the user has

configured the DSPbR using the web browser.

3.3.1 PSU Inlet Module

The PSU inlet module is a power-conditioning module. There are three versions of this module; 240VAC,

110VAC and a 48VDC. Both the 240AC and 110VAC inlet modules have an IEC320-C19 socket into which the

provided and respective mains power cord is plugged. The inlet module provides a degree of mains surge

protection.

Although the AC PSU module accommodates an input voltage range from 110V to 240V, the appropriate 110V

or 240V AC inlet module has to be fitted.

3.3.2 PSU Module

The PSU module is designed as modular and removable from the front of the repeater. Preceding the AC PSU

is the appropriate inlet module. Currently, two PSU modules are available, 110VAC/60Hz to 240 VAC/50Hz AC

and a 48VDC version.

To remove the PSU module, unscrew the six front mount screws from the front of the unit as illustrated in

Figure-4.

DSPbR Series – User’s Manual When removing or replacing the PSU, ensure to disconnect or connect the in-line plug / socket into the inlet module. There are three replaceable inverter fuses located within the AC PSU module and in order to check or replace any of these fuses, the PSU has to be unscrewed from the sub rack frame as previously illustrated in Figure-4, lever forward on the guide rails using the available handle far enough to access the fuse holders as illustrated in Figure-5.
