Redundant communication adapter system for connecting a client to an FDDI network

摘要

A communications adapter system having a server, a pair of redundant I/O boards, a pair of redundant network interface cards and a pair of redundant switches. A software program monitors the system for failures, and is typically stored in the memory of the server. The system is fully redundant and can check connectivity from the server to a remote network device. The system can also run on FDDI systems.
