Product Short Description
The T8310 is a 6U rack-mounted expansion processor that extends the Trusted Triple-Modular-Redundant (TMR) architecture across multiple chassis. It acts as a slave interface between the high-speed Expander Bus and the local backplane, enabling fault-tolerant inter-module communication over unshielded twisted-pair (UTP) cable at 250 Mbps .
