Hot Standby Status
Introduction
The active condition of a hot standby can easily be reviewed via the hot standby status window. To access this window, go to:
Monitoring -> Hot Standby Status.
Alarms for a particular radio can be reset, by clicking the Reset button at the bottom of the respective radios alarms column.
Latched Alarms
Once some alarms within a radio have been detected in a their most severe state, the hot standby will no longer dynamically
switch over to that radio, to help prevent switching over to a non-functional radio. These type of alarms are called ‘Latching
Alarms’.
Latching alarms may be reported in a recovered state, but will prevent the hot standby from dynamically changing over to the
respective radio, until the alarms have been manually reset.
The list of latching alarms include:
• Tx Power
• PLL Lock
• Operational
A Manual changeover on the front panel switch, or remotely forces change-over, can over-ride, but not clear, a latched alarm.
