10/100BaseTx fault tolerant redundant link protector

The SBFTF1010-130 is a fault-tolerant redundant link protector which provides redundant paths for fast Ethernet devices. It has three ports: main, primary, and backup. Typically, the main port connects to a critical 10/100 fast Ethernet device. The primary port and the backup port connect to two different switch ports or two different ports on separate switches. When the unit powers up, it checks the primary port for a link signal; if the signal is present, the main and primary ports connect and the signal from the backup port is then disabled. Any device connected to the backup port will not detect a signal at this time. However, if the device does not detect a signal on the primary port, then the main port and backup port connect.

Auto-Negotiation (selectable)

The Auto-Negotiation feature automatically configures the bridging media converter to achieve the best possible mode of operation over a link. The bridging media converter broadcasts its speed (10 Mbps or 100 Mbps) and duplex capabilities (full or half) to the other devices and negotiates the best mode of operation. Auto-Negotiation allows quick and easy installation because the optimal link is established automatically—no user intervention is required.

Redundancy (selectable)

If the primary port fails with redundancy enabled the converter automatically switches data transfer responsibilities to the backup port. After the primary port's failure is resolved, the converter automatically switches data transfer responsibilities back to the primary port.  If redundancy is disabled the unit functions as a 3 port switch.

If the primary path loses its link, then the transceiver will switch to the backup path in approximately 189 milliseconds.
