MIL-FT240TX
10/100 Fault-Tolerant Stand-Alone
Transceiver
• 10/100 Base-T(x) to 10/100 Base-T(x)
• Ethernet/Fast Ethernet
The MIL-FT240TX is a fault-tolerant
transceiver, providing 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 will connect and the
signal from the backup port is 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.
