Replacing an Enclosure Management Module
The SC200 and SC220 enclosures support redundant hot-swappable enclosure
management modules (EMMs).
EMMs provide the following data path and enclosure management functions for the
enclosure:
•
Monitoring and controlling enclosure environment elements such as temperature, fan,
power supplies, and enclosure LEDs
•
Controlling access to hard drives
•
Communicating enclosure attributes and states to the enclosure
Identifying the Failed Enclosure Management Module
To determine which EMM failed, use the Storage Center System Manager.
1
In the System Tree, expand the
Enclosures
entry.
2
Expand the failed enclosure entry (indicated with a red dot).

Click
IO Modules
. The status of each EMM is displayed.

To see the location of the failed EMM, expand the
IO Modules
entry, and click on the
failed EMM entry to display a rear view of the enclosure.
Note:
Allow several seconds for the enclosure to recognize the hard drive and
determine its status. When functioning properly, the hard drive’s status LED turns
green. In addition, the hard drive indicator turns green in the Storage Center
System Manager.
