Elma Bustronic Corp. has teamed up with European sister-company Elma TreNew to develop a new line of VITA 31.1 backplanes which incorporate switched fabrics into legacy VME64x backplanes with backwards compatibility.
The Elma Bustronic 8-slot VITA 31.1 Gigabit Ethernet backplane features
two fabric slots for dual redundant routing of the switch fabric across
the P0 connectors. As the P0 connectors in VME64x are undefined, the
payload slots of the backplane are fully backwards-compatible.
VITA 31.1 adopts the PICMG 2.16 P3 connector pinout for use on VME64x boards. It
also incorporates the definition of the fabric card described in PICMG
2.16. VITA 31.1 systems and PICMG 2.16-compliant systems can use the same
switched fabric boards.
Additional features of the Elma Bustronic 6U VITA 31.1 backplane include
an automatic active daisy chain, passive inboard termination, and M3/M4
power bolts for power. The backplane also meets the VITA 1.7 Increased
