3.2 Hardware Structure of the BTS3900

According to different input power supplies, the BTS3900 cabinets can be classified into -48 V

cabinet, +24 V cabinet, and +220 V cabinet. The hardware structure of the cabinet varies with

power distribution.

3.2.1 Structure of the BTS3900 -48 V Cabinet

The BTS3900 -48 V cabinet uses the external -48 V DC input. The DC power is directly led into

the DCDU-01 and the DCDU-01 distributes the DC power to each component in the cabinet.

The BTS3900 -48 V cabinet can be installed alone, stacked on another BTS3900 -48 V cabinet,

or installed side by side with another BTS3900 -48 V cabinet.

3.2.2 Structure of the BTS3900 +24 V Cabinet

The BTS3900 cabinet (+24 V) uses the external +24 V DC input. The PSUs (DC/DC) convert

the external input power into -48 V DC power and supply the -48 V DC power to the DCDU-01.

Then, the DCDU-01 distributes the -48 V DC power to each component in the cabinet. The

BTS3900 +24 V cabinet can be installed alone or side-by-side with another BTS3900 +24 V

cabinet.

3.2.3 Structure of the BTS3900 220 V Cabinet

The BTS3900 cabinet (220 V) uses the external 220 V AC input. The PSUs (AC/DC) convert



BTS3900 220 V cabinet can be installed alone or side-by-side with another BTS3900 cabinet(220 V).
