Enclosure Management Modules (EMMs)
The Enclosure Management Modules (EMMs) that are installed in the
enclosure are displayed under the EMMs object in the tree view. You can
select the EMMs object to display the individual EMM modules and their
status information.
The enclosure may contain one or more EMMs. The EMM modules monitor
components of the enclosure. These components include:
•Fans
Power supplies
Temperature probes
The insertion or removal of a physical disk
The LEDs on the enclosure
When the enclosure’s alarm is enabled, the EMM activates the alarm when
certain conditions occur. For more information on enabling the alarm and
the conditions that activate the alarm, see Enable Alarm (Enclosure). For
more information on EMMs, see the enclosure hardware documentation.
All EMM modules in the enclosure should have the same version of firmware.
You can view the properties of each individual EMM module to verify the
firmware version.
