3.4.1.1 2E42-27 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.

steps until it is on:
a. Verify that the 10BASE-T device at the other end of the twisted
pair segment is ON and connected to the segment.
