SM-2501CA Advanced Copper Link Protector®/Failover Switch
Model #: SM-2501CA
The SM-2501CA Advanced Copper Link Protector® provides a programmable automatic link backup capability to "mission-critical" 100BaseTX or 10BaseT Ethernet links. The device protects vital connections to servers, routers, and other key devices that require fail-safe operation. The SM-2501CA operates by monitoring "primary" and "backup" links and, in the event of a failure, automatically switching to the operational link. The unit shares many advanced features of the high end SM-2701FE Copper card for the NPC-2/12 systems including maintaining all links in the "UP" state for much faster switching to the Backup port. The SM-2501CA also has advanced traffic-failure switching triggers that allow it to respond to a broad range of "absence of packets" failure conditions. The SM-2501CA can also be purchased with an optional 4-port appliance backup capability.
