3.5.2Connecting UTP Cables to Ports 1 Through 24 of the 6E133-25 and 6E123-26

When facing the front panel of the 6E133-25 or 6E123-26, the upper RJ21 is the connector for 10BASE-T ports 1 through 12. The lower RJ21 is for 10BASE-T ports 13 through 24. All 24 ports have internal crossovers.

Connect a twisted pair segment to the 6E133-25 and 6E123-26 as follows:

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

2.If using an RJ21 straight connector, plug it into the appropriate RJ21 port as shown in Figure 3-4or, if using the RJ21 angle adapter supplied with the device, insert the RJ21 angle adapter as shown in Figure 3-5. The RJ21 angle adapter allows the cable to be inserted without interfering with the proper attachment of the second connector.
