14.4.47 FANDEGRADE

•
The degrade of the cooling fan-tray alarm indicates a problem with the fan-tray assembly. When the fan
is not fully functional, the temperature of the ONS 15327 can rise above its normal operating range. The
fan tray contains six fans and needs a minimum of five working fans to properly cool the ONS 15327.
However, even with five working fans, if a fan tray is not working properly, it may need to be replaced.
Always use the supplied ESD wristband when working with a powered ONS 15327. Plug the wristband

14.4.48 FE-AIS

•
The far end AIS (FE-AIS) alarm means the far-end node XTC card is reporting an AIS. The prefix FE
in an alarm message means the main alarm is occurring at the far-end node and not at the node reporting
this FE-AIS alarm. Troubleshoot the FE alarm by troubleshooting the main alarm at its source. Both the
alarms clear when the main alarm clears.
