220 alarm. It is an indicator that the laser in the card must be replaced. How soon the replacement must happen
depends upon the HI-LASERBIAS alarm threshold. If the threshold is set under 100 percent, the laser
replacement can usually be done during a maintenance window. But if the HI-LASERBIAS threshold is set
at 100 percent and is accompanied by data errors, LASEREOL indicates the card must be replaced sooner.

The Laser Temperature Degrade alarm occurs when the Peltier control circuit fails on an amplifier card
(OPT-BST, OPT-PRE, OPT-AMP-C, and OPT-AMP-17-C). The Peltier control provides cooling for the
amplifier.

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
Before disconnecting any optical amplifier card fiber for troubleshooting, ensure that the optical amplifier card
is unplugged.
