Does Positron make 130 Vdc to 48 Vdc power supplies to power station side loop-back equipment?
With the older shelves, the physical makeup of the station motherboard of the shelf does not allow a 48 Vdc to originate on the shelf and be routed outside the shelf. In addition, there is no connection on the back plane of the shelf to allow an output of 48 Vdc from a supply to be connected to the motherboard. With the new version of the 5 and 8-card shelves, it is possible to supply a 48 Vdc power to power the station side loop back equipment. For the 5-card shelf, refer to figure 4 of the 751112/1 installation guide. For the 8-card shelf, refer to figure 4 of the 751109/13 installation guide.
