Indicator Color Description
STAT LED
Red Indicates a hardware fault; this LED is off during normal operation.
Replace the card if the STAT LED persists. During diagnostics, the LED
flashes quickly during initialization and slowly during configuration
synchronization.
SRV LED

Indicator Color Description
SD LED
Blue The blue SD LED indicates a signal degrade (SD) or condition such as
a low level signal on at least one of the card’s ports.
SF LED
Red The red SF LED indicates a signal failure (SF) or condition such as loss
of signal (LOS), loss of frame alignment (LOF), or turns on when the
transmit and receive fibers are incorrectly connected. When the fibers
are properly connected, the LED turns off.
