Cable bundles
The DC cables from the three Power Supply Units to the Transceiver Unit are all separate conductors in a bundle. 230 VAC is also included in order to power the fans in each TRXU subrack.
Inside the Transceiver Unit, the power cables are terminated in three TRXU Terminal blocks, one for each subrack. From these terminal blocks, the three DC cable bundles are fed up to the rear side of the subrack, and terminated with plugs on the Power Connector Panel. The AC power provided by the Power Supply Units is also terminated on the Power Connector Panel.
