Back-Panel Features
Enclosure Management Module (EMM)
Each EMM provides data path and enclosure management functions for your enclosure, including:
•
Monitoring and controlling enclosure environment elements (temperature, fans, power supplies, and
enclosure LEDs)
•
Controlling access to the drives
•
Communicating
enclosure
attributes and states to the host server
NOTE:
At least one EMM must be installed in the enclosure. If only one EMM is installed, it must be in the
primary EMM bay (see Figure 1-4) and a blank module cover must be installed in the secondary EMM bay
(see "Installing an EMM Module Cover in an Empty Bay").
Figure 1-5 shows a single EMM as it appears from the rear of the enclosure. The EMM connects to the
enclosure via the enclosure midplane (see "Removing and Installing an EMM"). EMM connectors and
components are shown in Figure 1-5 and include:
•
Debug port (Dell use only)
•
SAS port connector (In)
•
SAS port connector (Out)
•
Three LEDs (In Port Link, Out Port Link, and EMM Status)
