GAIN-HFAIL

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

GAIN-HFAIL
Default Severity: Critical (CR), Service-Affecting (SA)
Logical Object: AOTS
The Gain High Degrade alarm is raised on an amplifier card (OPT-BST, OPT-PRE, OPT-AMP-C, or
OPT-AMP-17-C) when the amplifier reaches the Gain High Degrade Threshold. (This value is automatically
provisioned with the gain setpoint, but the alarm threshold is 5 dBm higher than the setpoint.) The GAIN-HFAIL
alarm is also raised on the 40-SMR1-C and 40-SMR2-C cards. If the alarm cannot be cleared, the card must
be replaced.
Note This alarm is applicable only when the amplifier working mode is set to Control Gain.
