D-Link DES-2212 manual MII Connection

User’s Guide

Ports 1 through 4 are NWay 10/100Mbps ports. When you connect a station to one of these ports, the corresponding port Link/Act LED should light. For 100Mbps connections, the corresponding 100M LED indicator should also light.

When connecting to a hub or an Ethernet switch with an MDI-X port, you can use a crossover cable, or you can directly use the Uplink port. You can connect the uplink port directly to a 100BASE-TX Ethernet hub or switch using straight-through cable.

NOTE: Port 1 and the Uplink port are MDI-X and MDI versions of the same port. If you are using the Uplink port, you cannot use Port 1, and vice versa.

MII Connection

The switch’s back panel features an industry-standard MII connector, allowing you to attach transceivers for other types of 100BASE-X media, such as 100BASE-FX or 100BASE-T4.

To connect a device using the switch’s MII port,

1.Make sure that the switch is turned off whenever connecting a transceiver to the MII port (or when removing it).

2.Set the transceiver’s address setting to 2, if it has one. (The MII port is shared with the switch’s port 2).

3.Attach the transceiver to the MII port at the rear of the switch.

4.Power on the switch. If there is a good link through the transceiver connected to the MII port, both the MII-II LED and the Link/Act LED for port 2 should light.
