Drive status indicators
Green and amber LEDs on the front of each drive carrier module indicate disk drive status. The SEP controls these LEDs.

Dummy drive carrier modules
Dummy drive carrier modules, also known as drive blanks, are provided in 3.5" (2U12) and 2.5" (2U24) form factors. They
must be installed in empty disk drive slots to create a balanced air flow.

Enclosure management
SBB IOMs actively manage the enclosure. Each module has a SAS expander with its own storage enclosure processor
(SEP) that provides a SES target for a host to interface to through the ANSI SES Standard. If one of these modules fails,
the other module will continue to operate.
Refer to a module's specification or the SES Interface specification for definitions of the module's functions and its SES
control. See also
Management interfaces
Upon completing the hardware installation, you can access the controller module's web-based management
interface—Storage Management Console (SMC)—to configure, monitor, and manage the storage system. See also
"Accessing the SMC" (page
The controller module also provides a CLI in support of command entry and scripting.
