SM-2500 Link Protector

 






 
 

horizontal rule

The SM-2500 Link Protector provides a fully automatic link backup capability to "mission-critical" 100BaseTX and 10BaseT Ethernet links. Protects vital connections to servers, routers, and other key Ethernet devices that require fail-safe link operation. The SM-2500 operates by non-intrusively 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 or an entirely different hub altogether for greater protection.

Key Benefits

bulletHandles Both 100BaseTX and 10BaseT Link Technologies
bulletNon-Intrusive Monitoring of Primary and Backup Network Connections
bulletAutomatic Switching in the Event of Link Failure
bulletMaintains Protected-to-Primary Port Connection During Power Failure
