14.4.47 FANDEGRADE
•
Major, Non-Service-Affecting
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.
Caution
Always use the supplied ESD wristband when working with a powered ONS 15327. Plug the wristband
cable into the ESD jack located on the lower-right outside edge of the shelf assembly.
Procedure: Clear the FANDEGRADE Alarm
Step 1
Check the condition of the air filter to see if it needs replacement.
Step 2
If the filter is clean, take the fan-tray assembly out of the ONS 15327.
Step 3
Reinsert the fan tray making sure the back of the fan tray connects to the rear of the ONS 15327.
Note
The fan should run immediately when correctly inserted.
Step 4
If the fan does not run or the alarm persists, replace the fan tray.
14.4.48 FE-AIS
•
Not Alarmed (NA) (Condition)
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.
