NOTE:Use the PowerVault Manager to monitor the storage system event logs for information about enclosure-related events, and to determine any necessary recommended actions.

Thermal considerations

NOTE:Thermal sensors in the 5U84 enclosure and its components monitor the thermal health of the storage system.
  • Exceeding the limits of critical values activates the over-temperature alarm.
  • For information about 5U84 enclosure alarm notification, see Table 1.
