Update
Steve one of our network guys is looking into the issue with the switch and to understand what went wrong with it.

Failover, We operate 2 independant switches in each Server Rack.
the current failover setup relies only on the link status that the network adapter provides. This option detects failures such as removed cables and physical switch power failures.

Inlight of this issue today. we are exploring Beacon probing which sends out and listens for beacon probes on all NICs on the servers, and uses this information, in addition to link status, to determine link failure and sends beacon packets every second. If no reply is received - the NIC which connects to the Switch is automatically removed from service and serivce is resumed by the other switch.
