The TPIM-T2 supports UTP cabling and the TPIM-T4 supports STP 
cabling. The method for connecting an RJ45 connector to an RJ45 port 
is the same for both UTP and STP cabling. Before connecting a 
segment to the TPIM-T2 /T4, check each end of the segment to ensure 
the wires are pinned properly. To connect a segment to a TPIM-T2/T4:

1.

Insert the RJ45 connector on the twisted pair segment into the 
RJ45 port on the TPIM as shown in Figure 3-14.

Check that the LNK LED on the TPIM lights green. If the LED 
lights red or is not lit, perform each of the following steps until it is:

a.

Check that the device at the other end of the segment is on.

b.

Verify that the RJ45 is pinned properly.

c.

Check the cable for continuity.

d.

Check that the twisted pair connection meets dB loss and cable 
specifications outlined in Chapter 2.

e.

Check that the port is enabled through Local Management.
