Replacing an Enclosure Management Module

The SC100/SC120 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

To determine which EMM failed, use the Dell Storage Client.
1. Click the Hardware tab.
2. In the Hardware tab navigation pane, select the Storage Center.
3. In the Hardware Alerts area, find the hardware alert that identifies the enclosure with the failed EMM
(IO Module).
