*If multiple conditions occur simultaneously, the LED state will behave as indicated by the condition listed earliest in the table, as rows are
read from top to bottom.
Each DDIC has a single Drive Fault LED. A disk drive fault is indicated if the Drive Fault LED is lit amber. In the event of a disk failure, follow
the procedure in Replacing a DDIC.
IOM LEDs
NOTE
: IOM CRUs are common to the 2U and 5U84 enclosures.

Troubleshooting 2U enclosures
The following sections describe common problems that can occur with your enclosure system, and some possible solutions. For all of the
problems listed in Table 20. 2U alarm conditions , the Module Fault LED on the Ops panel will light amber to indicate a fault. All alarms also
report using SES.
Table 20. 2U alarm conditions
