The SM-2601F Intelligent Fiber Link Protector provides a
fully managed automatic link backup capability to "mission-critical"
1000BaseSX or 1000BaseLX Fiber Ethernet links. Protects vital connections to
servers, routers, and other key devices that require fail-safe operation.
The SM-2601F operates by monitoring a "primary" link and, in the event of a
failure, automatically switches to the backup link. The Link Protector does
not require any additional network cards in a server and does not require
router-level switchovers if a failure occurs. The backup link can be
connected to either another port on a switch or an entirely different switch
for greater protection. The unit contains a dual Mode Protected Port (one LC
Fiber and one RJ45 Copper) for a redundant station port configuration. The
unit also functions in a back-to-back configuration for redundant cable path
applications.
Key Benefits
 | Automatic or SNMP-based Switching Capability Between Primary and
Backup Links |
| Non-Intrusive Monitoring of Primary and Backup Network Connections |
| Automatic Switching in the Event of Link Failure |
| Additional Copper 1000BaseT Port for Server Redundancy |
| Redundant 48VDC and/or 100/220VAC Power |
