• Connect the twisted pair segment (4, Fig. 3-1) by inserting

the RJ-45 connector (3) into the adapter’s RJ-45 port (2).

• Check that the Link LED on the adapter is lit. The Link

LED may not light until data has been transmitted out the

10BASE-T port.

If you know the adapter has attempted to transmit data and the

LED is not lit, check the items listed here:

• Verify that the power is on for the PC.

• Check that the 10BASE-T device at the other end of the

twisted pair segment is powered up.

• Verify that the RJ-45 connector on the twisted pair segment

has the proper pinouts (see Figure 3-2, above).
