10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) port located on the VPort D351’s front panel is used to connect to
Ethernet-enabled devices.
Below we show pinouts for both the MDI (NIC-type) port and MDI-X (HUB/Switch-type) port,
and we also show cable wiring diagrams for straight-through and cross-over Ethernet cables.
