Product Description
The MIL-240 Redundant Port Selectors make up a family of Fast Ethernet fault-tolerant transceivers. They significantly reduce network downtime, adding a new level of redundancy to Fast Ethernet connections. They also provide a redundant path for critical fast devices. In a Fast Ethernet network, a critical device such as a file server may be connected to the rest of the network through a hub or a switch. A common problem in this configuration is that the server is often connected to the network through a single cable. If the cable fails, then the server is disconnected from the rest of the network. Similarly, if a port of a hub or switch to which the server is connected fails, the server is disconnected from the network. The MIL-240 Redundant Transceivers have three ports: one for the critical (main) device, one for the default (primary) path for the critical device, and another (backup) for the backup path. They are smart devices that will not send any signal on a path that is not active. If the primary path loses its link, then the MIL-240 will immediately (in less than one microsecond) switch to the backup path. When the primary path re-establishes its link, the MIL-240 Redundant Port Selector family will automatically switch back to the primary path.
