The status of this alarm entry. An alarm becomes active if the underlying condition is detected. For power supplies, the input failed alarm condition is asserted if the input voltage is not within the nominal range for the supply. This does not necessarily mean that an ouput failure will result. A power supply output failure condition is asserted if any power supply is failing or if it is physically removed. Power supply output alarms are only applicable to switches with multiple power supplies. Fan bank and temperature sensor failures are applicable only to switches with the appropriate sensing capabilities. Link and spans failures are applicable to all switches.
