Note: When installing Mini-GBICs in the front-panel ports 1 through 18, you may
need to select a group of ports to verify the port operation. Initially GROUP 1 LED is
green, indicating that the status RX/TX LEDs are showing the activity on Group 1
ports (1 through 6). To view the receive and transmit activity on another group, press
the GROUP SELECT button for less than one second (refer back to Figure 3-9) to
step to the next GROUP (1, 2, or 3) of 6 ports. The receive and transmit activity for
that group of segments is then indicated by the RX and TX LEDs for each segment.
Note: If a link has not been established, refer to Chapter 4 for LED troubleshooting
details. If the problem persists, refer to “Getting Help” on page 1-8 for details on
contacting Enterasys Networks for support.
