3.4.1.12E42-27 or 2E42-27R Cable Connections

Ports 1 through 24 of the 2E42-27 or 2E42-27R 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.

To connect an RJ45 twisted pair segment, proceed 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 2E42-27 by inserting the RJ45 connector on the twisted pair segment into the desired RJ45 port (Ports 1 through 24) as shown in Figure 3-6.
