8.1.4Power Supply Sensors

Each SANnet II 200 FC, SATA, and SATA SE array has two fully redundant power supplies, with load sharing capabilities. The sensors monitor the voltage, temperature, and fan units in each power supply.

8.2Silencing Audible Alarms

An audible alarm indicates that either a component in the array has failed or a specific controller event has occurred. Error conditions and controller events are reported by event messages and event logs. Component failures are also indicated by LED activity on the array.
