Interpreting the LEDs

The ATM uplink card has one link LED. If there is a valid link, the LED is solid

green. If the uplink card is not connected to any device, or there is a problem

with the link, the LED is off.

The FDDI uplink card has two LEDs. Table 1 provides information about what

the LEDs mean in various states.
