Cable, Port, and Pinout Information
This section describes the switch’s physical interfaces and provides information about cable
connections.
Stations are connected to the switch’s ports through the physical interface ports on the front panel.
For each station, the appropriate mode (Half/Full Duplex, Auto) is set.
Pin Connections for the 10/100/1000 Ethernet Interface
The switching port can connect to stations wired in standard RJ-45 Ethernet station mode using
straight cables. Transmission devices connected to each other use crossed cables.
Figure 3-1 illustrates the RJ-45 pins, and Table 3-1 contains the RJ-45 pin allocations.
