“Enclosure management” allows managing enclosure information including “SES
configuration”, “Hardware monitor”, “S.M.A.R.T.” and “UPS”. For the enclosure
management, there are many sensors for different purposes, such as temperature
sensors, voltage sensors, hard disk status, fan sensors, power sensors, and LED
status. Due to the different hardware characteristics among these sensors, they have
different polling intervals. Below are the details of the polling time intervals:
1. Temperature sensors: 1 minute.
2. Voltage sensors: 1 minute.

4. Fan sensors: 10 seconds . When there are 3 errors consecutively, system sends
ERROR event log.
