:
This LED indicates a change of status or fault from something other than the enclosure management
system. This 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.

:
Opening a drawer does not interrupt the functioning of the storage system.
DDICs can be hot-swapped while the enclosure is in operation. However,
drawers must not be left open for longer than two minutes, or airflow
and cooling will be compromised.
NOTE:
During normal operation, drawers should be closed to ensure
proper airflow and cooling within the enclosure. A drawer is designed
to support its own weight, plus the weight of installed DDICs, when
fully opened.
