Warning
Invisiblelaser radiation may be emitted from the end of the unterminated fiber cable or connector. Do
not stare into the beam or view directly with optical instruments. Viewing the laser output with
certainoptical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance
of100 mm may pose an eye hazard. Use of controls or adjustments or performance of procedures other
than those specified may result in hazardous radiation exposure.

Indicators Color Description
STAT LED Red Indicates a hardware fault; this LED is off during normal operation.
Replacethe card if the STATLED persists. During diagnostics, the LED
will flash quickly during initialization and flash slowly during
configuration synchronization.

Indicators Color Description
SD LED Blue Theblue SD LED indicates a signal degrade 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 or condition such as LOS,
LOF,or high BERs on at least one of the card’s ports. The red SF LED
also illuminates when the transmit and receive fibers are incorrectly
connected. When the fibers are properly connected, the LED turns off.
