Warning
Invisible laser 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
certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a
distance of 100 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.

Card-Level Indicators Description
Red FAIL LED
The red FAIL LED indicates that the card’s processor is not ready. Replace
the card if the red FAIL LED persists.
ACT/STBY LED
Green (Active)
Amber (Standby)
When the ACTV/STBY LED is green, the OC-192 card is operational and
ready to carry traffic. When the ACTV/STBY LED is amber, the OC-192
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 the card’s port. The amber SF LED also illuminates when
the transmit and receive fibers are incorrectly connected. When the fibers are
properly connected, the light turns off.
