RJ45 (10-pin) to DB9 (F) Cable Wiring
10/100/1000BaseT(X) Ethernet Port Connection
The 10/100/1000BaseT(X) ports located on 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.
The following charts display the pinouts for both MDI (NIC-type) ports
and MDI-X (HUB/Switch-type) ports. We also present cable wiring
diagrams for straight-through and cross-over Ethernet cables.
