Enclosure Management Module

Each EMM provides the following data path and enclosure management functions for your enclosure:

• Monitoring and controlling enclosure environment elements such as temperature, fan, power supply units, and enclosure LEDs.

• Controlling access to hard disk drives.

• Communicating enclosure attributes and states to the host server.

NOTE:

installed in the primary EMM bay and a blank must be installed in the secondary EMM bay. See Installing an EMM blank .

At least one EMM must be installed in the enclosure. If only one EMM is installed in the enclosure, it must be

Enclosure failover when two EMMs are installed

If two EMMs are installed, a certain degree of failover is offered. Control and monitoring of the enclosure elements can be transferred from one EMM to another in the event of an EMM failure. A failover occurs whenever network communication is ended between an EMM and its peer.

In the event of a peer EMM failure, the surviving EMM activates the amber status LED of the failed EMM. The surviving EMM then takes over the responsibility of enclosure management, which includes monitoring and control of the enclosure LEDs, power supply units, and fans.

EMM thermal shutdown

If critical internal temperatures are reached, the enclosure turns off automatically through either a thermal shutdown command issued by the EMM firmware or through a command from Dell OpenManage Server Administrator.
