Crossover Cable

When cascading or connecting the hub to another switch, bridge, or hub through the UTP port, a modified crossover cable is necessary. With a crossover cable, two pairs of wires are switched at one connector end. Carry out the following steps to create a customized, crossover twisted-pair cable:

1.Leave one end of the cable as is, with the RJ-45 connector intact. The wiring at just one end of the cable needs to be modified.

2.At the other end of the cable, connect wires 1 and 2 to contacts 3 and 6 respectively. Likewise, connect wires 3 and 6 to contacts 1 and 2. Refer to the following diagram:

Hub (MDI-X)					Switch (MDI-X)
		RD+	RD+	1
	1	RD+	RD+	1
	2	RD-	RD-	2
	3	TD+	TD+	3
	6	TD-	TD-	6

MII Connector

The MII (Media-Independent Interface) is a standard 40-pin connector that you can use to connect other types of 100Mbps network media to your DES- 2212. Using a transceiver connected to the MII port on the rear panel of your switch, you can connect the switch to a 100BASE-FX or 100BASE-T4 link.

This appendix shows the pin assignments for the MII connector, which is specified in the IEEE 802.3u Fast Ethernet standard.
