F.2 Managing Enclosures
An enclosure management processor (EMP) is a device in the enclosure from which the Galaxy 65
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 Galaxy 65 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 Galaxy 65
