Constant or blinking: system hardware fault. The module fault LED may be
associated with a Fault LED on a controller module, IOM, PSU, FCM, DDIC,
or drawer.
Logical status LED
Amber
Constant or blinking: fault present from something other than the enclosure
management system. The logical status LED may be initiated from the
controller module or an external HBA. The indication is typically associated
with a DDIC and LEDs at each disk position within the drawer, which help to
identify the DDIC affected.

This section describes the controller modules used in 12 Gb/s storage enclosures. They are mechanically and electrically
compliant to the latest SBB v2.1 specification.
The following figure shows a 4-port SAS controller module aligned for use in the top slot located on the 2U enclosure rear panel.
The controller module is also properly aligned for use in either slot located on the 5U84 enclosure rear panel.
