2.7.27 AUD-LOG-LOW
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Default Severity: Critical (CR), Service-Affecting (SA)
SONET Logical Object: OCN
The Auto Laser Shutdown alarm occurs when the OC-192 card temperature exceeds 194 degrees F
(90 degrees C). The internal equipment automatically shuts down the OC-192 laser when the card
temperature rises to prevent the card from self-destructing.
Warning
On the ONS 15454 OC-192 card, the laser is on when the card is booted and the safety key is in the on
position (labeled 1). The port does not have to be in service for the laser to be on. The laser is off when
the safety key is off (labeled 0).
Statement 293
Warning
Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector.
Do not stare into the beam 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 could pose an eye hazard.
Statement 1056
Warning
Use of controls, adjustments, or performing procedures other than those specified could result in
hazardous radiation exposure.
Statement 1057
Clear the AUTOLSROFF Alarm
Step 1 View the temperature displayed on the ONS 15454 LCD front panel (Figure 2-1).
