Connecting the 10/100Base-T Ethernet Port to a Hub or PC

The Models 2156 and 2157 are equipped with an MDI-X switch that enables connections to a hub (DCE) or PC (DTE) interface, thereby elimininating confusion over whether a straight-through or crossover cable is needed.

When using a straight-through cable for connecting to a hub, the MDI-X switch should be in its released (DCE mode) position (see Figure 5). When connecting to a PC, the MDI-X switch should be pushed in to engage the crossover function so you won’t have to use a crossover cable

Note If you have difficulty achieving a working connection between the CopperLink Ethernet Extender’s Ethernet port and the hub or PC, change the position of the MDI-X switch and try again.

In its released position, the MDI-X switch enables straight-through con- nections (see Figure 6) or in its inserted position the MDI-X switch per- forms the crossover function (see Figure 7 on page 11).
