Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect the IESH-MB’s
10/100BaseT(X) ports to any kind of Ethernet device, without paying
attention to the type of Ethernet cable being used for the connection.
This means that you can use either a straight-through cable or cross-
over cable to connect the IESH-MB to Ethernet devices.
