Auto-MDIX sensing is required. The maximum cable length is 
2 kilometers (1.24 miles).

CAUTION:

Do not connect pinned MT-RJ connectors into any port on the 

Switch 4400 FX as this may damage the unit. The ports have locator pins 
fitted and are designed for standard (pinless) connectors.

To connect a front-panel port to a 100BASE-FX single mode port, or to a 
port that does not have an MT-RJ connector, an adaptor will be required. 
It is not possible to connect a front panel port to a 1000BASE-FX port.
