Replacing an Enclosure Management Module

The SC180 expansion enclosures support redundant hot-swappable Enclosure Management Modules
(EMMs).
EMMs provide the following data path and enclosure management functions for the expansion
enclosure:
•
Monitoring and controlling expansion enclosure environment elements such as temperature, fan,
power supplies, and expansion enclosure LEDs
•
Controlling access to hard drives
•
Communicating expansion enclosure attributes and states to Storage Center

Identifying the Failed Enclosure Management Module

Start the Dell Storage Client and connect to the Storage Center that has an expansion enclosure with
a failed EMM.
2.
Click the Hardware tab.
3.
In the Hardware tab navigation pane, select and expand the Storage Center.
4.
In the Hardware Alerts area, find the hardware alert that identifies the expansion enclosure with the
failed EMM.
