American Megatrends StorTrends 3600i Setup Manual page 18

By default, AUSM is configured to monitor UPS from Left Controller (LC) and LC will act as M aster.
During Failover (i.e. when LC goes down), AUSM will automatically start monitoring the Right Controller
(RC) and will switch back to LC automatically after Fail Back (i.e. LC comes up).
NOTE: It is recommended to configure UPS after the completion of Network Configuration Wizard.
To replace a hard drive follow the instructions from Appendix C – Replacing Failed
