SEP Modules

BittWare’s exclusive SEP (serial expansion port) allows the XUPP3R to be expanded for an additional PCIe Gen3 x16 slot, additional 4 QSFPs, or connection between two XUPP3Rs.

Active and Passive Cooling Options

In addition to standard active fan and heatsink cooling, the XUPP3R offers two passive options, standard and our new advanced passive cooling using heat pipes.
