PDF Icon Data Sheet

The SM-2501/SM-2501G Ethernet Link Protector®s provide a programmable automatic link backup capability to "mission-critical" 10/100BaseTX (SM-2501) and 10/100/1000BaseT (SM-2501G) Ethernet links. Protects vital connections to servers, routers, and other key Ethernet devices that require fail-safe link operation. The SM-2501/SM-2501G 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. The unit also functions in a back-to-back configuration for redundant wiring applications.
