10/100BaseT(X) Ethernet Port Connection

The 10/100BaseT(X) ports located on the Switch´s front panel are used to
connect to Ethernet-enabled devices. Most users will choose to configure
these ports for Auto MDI/MDI-X mode, in which case the port's pinouts are
adjusted automatically depending on the type of Ethernet cable used
(straight-through or cross-over), and the type of device (NIC-type or
HUB/Switch-type) connected to the port.
In what follows, we give pinouts for both MDI (NIC-type) ports and MDI-X
(HUB/Switch-type) ports. We also give cable wiring diagrams for
straight-through and cross-over Ethernet cables.
