SM-2501F Fiber Ethernet Link Protector

 






 
 

horizontal rule

The SM-2501F Fiber Link Protector provides a programmable automatic link backup capability to "mission-critical" 100BaseFX Fiber and 100BaseTX Ethernet links. Protects vital connections to servers, routers, and other key devices that require fail-safe operation. The SM-2501F operates by monitoring a "primary" link and, in the event of a failure, automatically switching to the backup link. The Link Protector does not require any additional network cards in a server and does not require router-level switch-overs if a failure occurs. The backup link can be connected to either another port on a hub/switch or an entirely different hub/switch altogether for greater protection. The unit contains a dual Protected Port (one SC Fiber and one RJ45 Copper) for a redundant station port configuration. The unit also functions in a back-to-back configuration for redundant cable applications.

Key Benefits

bulletAutomatic Switching Capability Between Primary and Backup Links
bulletNon-Intrusive Monitoring of Primary and Backup Network Connections
bulletAutomatic Switching in the Event of Link Failure
bulletAdditional Copper 100BaseTX Port for Server Redundancy
bulletRedundant 48VDC and/or 100/220VAC Power
