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:

To view the receive and transmit activity on a group of segments, press the
GROUP SELECT button (refer back to Figure
(Groups 1 through 3). 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.

used.
Verify that the device at the other end of the twisted pair segment is on and
properly connected to the segment.
pinouts and check the cable for continuity. Typically, a crossover cable is used
between hub devices. A straight‐through cable is used to connect between
switches or hub devices and an end user (computer). Refer to Figure
Figure 3‐6 for four‐wire RJ45 connections. Refer to Figure 3‐7 and Figure
