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 3-3) 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.

d.Verify that the RJ45 connectors on the twisted pair segment have the proper pinouts

(Figure 3-4and Figure 3-5) and check the cable for continuity. Typically, a crossover cable is used between a switching or hub device and an end user (computer). A straight-through cable is used between hub devices.
