RJ-45 ports (Auto MDI/MDIX):
JetNet 3008 has eight 10/100 Mbps
auto-sensing RJ-45 ports for 10Base-T or 100Base-TX device connection
and JetNet 3008f has six 10/100Mbps RJ-45 ports and two 100Mbps fiber
ports for multi-mode or single-mode fiber cable in SC type connector. The
RJ-45 ports will auto-detect 10Base-T and 100Base-TX connections. Auto
MDI/MDIX function allows users to connect another switch or workstation
without changing straight through or crossover cabling. See Figure C and
C-1 for the schematic diagram of straight through and crossover cabling.

Schematic
All RJ-45 ports of JetNet 3008/ JetNet 3008f support auto-MDI/MDI-X
function. When you use an Ethernet cable to connect other devices, such
as computers, switches or hubs, pin 1, 2, 3, and 6 of the 8-pin RJ45
connector are used to communicate with the connected devices. Pin1, 2,
3, and 6’s signals are converted by the MDI-X function, as shown in Table
-2.
