F.2 Managing Enclosures
An enclosure management processor (EMP) is a device in the enclosure from which the X24 Subsystem
can inquire about the enclosure's environmental conditions such as temperature, power supply and fan
status, and the presence or absence of disk drives. The X24 Subsystem can also tell the EMP about RAID
activities such as drive rebuilds and failed disk drives.
If you have only one EMP, the configuration settings are automatically enabled when the X24 Subsystem
