4.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 appropriate group. Each time the GROUP SELECT button is pressed, the GROUP LED lights up in sequence, indicating which Group is selected. On the 6H308-24 you can step to 1 or 2 for Group 1 or 2. On the 6H308-48, you can step to 1, 2, 3, or 4 for Groups 1 through 4. The receive and transmit activity for that group of segments is then indicated by the RX and TX LEDs for each segment.

b.If there are separate fiber optic connections on the other device, check the crossover of the cables. Swap the cable connections if necessary.
