6.1.1.2 Lists of alarms per system element
The following tables details all the alarms per system element type.
Table 13: HCM Alarms Descriptions
Alarm Name
Description
HW Failure
Faulty HCM hardware.
Adjustment Failure
Unsuccessful Adjustment procedure.
Installation Failure
Faulty physical installation between chassis.
SW Release
Mismatch
A module (or modules) in the system do not have the defined active release. Several
modules may not have corresponding software versions.
Connectivity
Faulty connectivity state in one of the previously discovered system modules
(module should appear gray in the networ
k topology).
Overall Status
Overall status of enabled (unmasked) alarms.
Table 14: ACM Alarms Descriptions
Alarm Name
Description
Overall Status
Overall status of enabled (unmasked) alarms.
HW Failure
ACM faulty
hardware upon initialization or during operation.
Over Temperature
Ambient temperature inside the ACM is greater than 75°C.
Inconsistent Version/ SW
Version
The module does not have the defined active release.
Adjustment Fault
Unsuccessful Adjustment procedure.
Ext1/Ext2 Clock Failed
Failure in master reference clock. Only relevant when ACM is installed in an
HEU or IHU chassis as follows:
•For ACM installed in an HEU chassis
- Ext1/Ext2 Clock Failed are relevant.
•For ACM installed in an IHU chassis - only Ext1 Clock Failed alarm is relevant.
Pilot Clock Failed
Relevant for IHU and OIU. Indicates failure in reference in the pilot clock in
the OIX Expander.
Fan Failure
Fault in at least one of the fan modules (i.e., fan does not match duty cycle
set value). Displays the highest severity alarm.
Power Failure
Power failure in one or both (if two are installed) of the PSMs.
Output Under Voltage
The ACM has detected an input voltage value under 10.8 V DC from one of
the PSM modules (severity
– minor) or both (severity – major) during three
consequent samplings.
Input Under Voltage
The ACM has detected an input voltage value of under 60 V AC from either
one PSM module (severity
– minor) /both PSMs (severity – major).
