2.1.11. Alarms Tab
A summary of the radio’s alarm status is available via the Alarms Tab, as shown in
Figure 21.
2.1.11.1. IDU Alarms
If the Demod Lock LED is green, the receiver is operational. Both nearand far-side
Demod Lock are necessary for bi-directional data transfer across the wireless link.
The Software Status indicator turns red if the Modem Supervisor is not executing
normally. The IDU modem may require reconfiguration on one or both sides of the
link, a restart, or a reboot to clear this alarm.
The Hardware Status indicator turns red if the IDU experiences a hardware failure.
Power-cycling the unit may clear this alarm. If not, it should be returned to the
factory for servicing.
2.1.11.2. IDU-ODU Alarm Status
The IDU-ODU Alarm Status indicator turns red if the communication link between
the IDU and the ODU goes down. For 1+1 protected units, the link status for both
the Primary and the Standby ODU is displayed.
2.1.11.3. Protected Mode Alarm Status
For 1+1 protected units, ODU 1 and ODU 2 Tx and Rx alarms are set to red if an
ODU hardware failure causes a switch away from a given path or if the ODU is
disconnected.
Restoring the system to power-on settings or disabling protected mode, replacing
an ODU, and re-enabling protected mode will clear and reset the Protected Mode
Alarm Status indicators.
