The four system host board (SHB) segments on the Trenton BP4FS6890 backplane are flexible enough to be ordered in either a graphics-class or server-class configuration. Each segment supports either a graphics-class or server-class SHB and two or three PCI express option card slots. Backplane versions are available that enable the SHB segments to operate independently or as part of the backplane’s 10/100/1000Base-T ethernet fabric network. Additional backplane ordering options are available that allow the segments to have power applied using either standard ATX/EPS power connectors or terminal blocks.
