Red FAIL LED

The red FAIL LED indicates that the card’s processor is not ready. This LED 
is on during reset. The FAIL LED flashes during the boot process. Replace 
the card if the red FAIL LED persists.

ACT/STBY LED

Green (Active)

Amber (Standby)

If the ACT/STBY LED is green, the card is operational (one or both ports 
active) and ready to carry traffic. If 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 LOS, LOF, 
or high BERs on one or more of the card’s ports. The amber SF LED is also 
on if the transmit and receive fibers are incorrectly connected. If the fibers 
are properly connected and the link is working, the light turns off.
