DS3-12E and DS3N-12E Card-Level Indicators
Description
The red FAIL LED indicates that the card processor is not ready. Replace the
card if the red FAIL LED persists.
When the ACT/STBY LED is green, the card is operational and ready to
carry traffic. When the ACT/STBY LED is amber, the card is operational and
in standby (protect) mode.
The amber SF LED indicates a signal failure or condition such as port LOS
or AIS.
