2. Connect the twisted pair segment to the module by inserting the RJ45 connector on
the twisted pair segment into the appropriate RJ45 port connector.
3. Verify that a link exists by checking that the port RX (Receive) LED is ON (flashing
amber, blinking green, or solid green). If the RX LED is OFF and the TX (Transmit)
LED is not blinking amber, perform the following steps until it is on:
a. To view the receive and transmit activity on a group of segments, press the
GROUP SELECT button (see Figure 3-8) to step to the group of interest (Groups 1
through 4). Each time the GROUP SELECT button is pressed, the GROUP LED
lights up in sequence, indicating which Group is selected. The receive and
transmit activity for that group of segments is then indicated by the RX and TX
LEDs for each segment.
b. Verify that the cabling being used is Category 5 UTP with an impedance between
85 and 111 ohms. If the port is to operate at 100 Mbps, category 5 cabling must be
used.
c. Verify that the device at the other end of the twisted pair segment is on and
properly connected to the segment.
