RJ-45 cable connections are made to both the front and rear of the ENIU. DB-9 (command line interface) connection
is made on the front and the power connection is made on the rear. A rear view of the ENIU is shown in
Figure 2-2
on page 2-3 . A front view is provided below in Figure 2-4 .

Step Action
1 Each ENIU has an RJ-45 connector located on the front and rear. Use this connector when making the
copper Ethernet connections. If an RJ-45 Patchcord is provided, proceed to
Step 2 . The following steps
describe how to make your own RJ-45 Patchcord. Pinout information is shown in Table 2-1 on page 2-5 ,
Table 2-2 on page 2-5 , and Figure 2-5 .
Figure 2-5. RJ-45 Connector Wiring
a. Use Cat5e or better cable, strip back cable jacket to expose the four wire pairs, the metallic sheath,
and drain wire (if present).
b. Cut off metallic sheath and drain wire (if present) so that it is even with the outer jacket of the cables.
c. IEEE Specification for Ethernet 10 or 100BaseT(X) requires that two twisted pairs be used and one
pair is connected to pins 1 and 2, and the second pair is connected to pins 3 and 6.
d. IEEE Specification for Ethernet 1000BaseT requires that four twisted pairs are used. One pair is
connected to pins 1 and 2, pair two is connected to pins 3 and 6, pair three is connected to pins 4
and 5, and pair four is connected to pins 7 and 8.
2 Connect Ethernet RJ-45 patchcords to the corresponding receptacles on the ENIU.
