Switch Node Interface LEDs
The Switch Node Interface (SNI) TN573 circuit pack has the standard red, green,
and yellow LEDs. The red and green LEDs have the traditional meaning, where
red indicates an alarm condition, and green indicates testing in progress.
The yellow LED displays various flashing patterns to provide status information
useful in isolating faults in the fiber link and other components connected to the
fiber link. Table 7-3
