1-2Fast Ethernet Network Interface CardsFast EthernetFast Ethernet is a networking standard defined by the Institute ofElectrical and Electronic Engineers (IEEE) in their IEEE 802.3uSpecification. Fast Ethernet runs at 100 Mbps or at 200 Mbps in FullDuplex mode.Fast Ethernet uses the same Carrier Sense Multiple Access withCollision Detection (CSMA/CD) architecture used on 10BASE-Tand 10BASE-2 10 Mbps network specifications, which allows foreasy integration with existing networks.Duralink FailoverDuralink™ Failover provides protection from system failures on FastEthernet servers running mission-critical applications. During a portfailure, Duralink Failover keeps the connection to the serverestablished by moving all traffic on the affected segment to astandby Network Interface Card (NIC) or port. When a failure isdetected on the primary port, that port is disabled and a secondaryport takes over to carry the load, and keeps the network runningwithout interruption.This Failover operation occurs when any of the following conditionsexist:n There is a link lossn A watchdog timer expiresn An abnormal hardware interrupt occursn Abnormal Send/Receive counters, such as too many collisionsor errors, occur on the segmentSupported Platforms and NICsDuralink Failover is supported for Windows NT™ and NovellNetware-based servers.Duralink Failover is compatible with Adaptec ANA™-6911A singleport NIC, ANA-6922A dual port NIC, and ANA-6944A quad portNIC.
