MDI
(Medium Dependent Interface) Port is also called an "uplink port". The MDI port
does not cross the transmit and receive lines, which is done by the regular ports
(MDI
-X
ports) that connect to end stations. In general,
MDI
means connecting to
another Hub or Switch while
MDIX
means connecting to a workstation or PC.
Therefore,
Auto MDI/MDIX
means that you can connect to another Switch or
workstation without changing non-crossover or crossover cabling.
LevelOne GSW-2491TXM has 24 auto-sensing 10/100Base-TX RJ-45 ports plus one
extension slot for (Optional) 1000Base-TX and miniGBIC module enables
long-distance connection or Gigabit copper module for higher connection speed.
