3.5.1Connecting UTP Cables to Ports 1 Through 24 of the DLE22-MA and DLE32-MA

Ports 1 through 24 of the DLE22-MA and DLE32-MA are 10BASE-T ports with internal crossovers. When connecting a workstation, use a straight-through cable. When connecting networking devices, such as another bridge, repeater, or router, use a crossover cable.

Connect a twisted pair segment to the DLE22-MA and DLE32-MA as follows:

1.Ensure that the device connected to the other end of the segment is powered ON.

2.Connect the twisted pair segment to the DLE32-MA or DLE22-MA by inserting the RJ45 connector on the twisted pair segment into the desired RJ45 port (Ports 1 through 24) as shown in Figure 3-2.
