Type of Cabling

Table 1 lists the cable specifications for the twisted pair port.

Auto

MDI/MDI-X

The wiring configuration of the twisted pair port is set automatically with
auto-MDI/MDI-X. Consequently, you can use a straight-through twisted
pair cable to connect any type of Ethernet network device to the port. The
auto-MDI/MDI-X feature is always active, even when the Auto- Negotiation
feature is turned off and the speed and duplex mode on the port are set
manually.
