10Base-T and 100Base-TX Ports

The switch provides IEEE 802.3u auto-negotiation on its 10Base-T/100Base- TX ports for 10/100 speed and full/half duplex operation. Table A-2 shows the 10Base-T/100Base-TX pinouts. These ports are wired MDI-X. All undefined pins are not used.

MDI/MDI-X Crossover Cable Wiring

Figure A-1 shows the wiring scheme for implementing a crossover cable if needed for connection to the switch’s 10Base-T or 100Base-TX ports. Such a cable may be required when connecting the switch to another switch or a hub device.
