Card-Level Indicators Description
Red FAIL LED The red FAIL LED indicates that the card processor is not ready. Replace the
card if the red FAIL LED persists.
ACT/STBY LED
Green (Active)
Amber (Standby)
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.
Amber SF LED The amber SF LED indicates a signal failure or condition such as port LOS
or AIS.
