No. Indicator Status
1 Unit Identification Display (UID) Green (seven-segment display: enclosure sequence)
2 System Power On/Standby
Constant green: positive indication
Constant amber: system in standby (not operational)
3 Module Fault Constant or blinking amber: fault present
4 Logical Status Constant or blinking amber: fault present
5 Top Drawer Fault Constant or blinking amber: fault present in drive, cable, or sideplane
6 Bottom Drawer Fault Constant or blinking amber: fault present in drive, cable, or sideplane
Unit identification display
The UID is a dual seven-segment display that shows the numerical position of the enclosure in the cabling sequence. The UID is
also called the enclosure ID.
NOTE: The controller enclosure ID is 0.
System Power On/Standby LED (green/amber)
LED is amber when only the standby power is available (non-operational). LED is green when system power is available
(operational).
Module Fault LED (amber)
LED turns amber when experiencing a system hardware fault. The module fault LED helps you identify the component causing
the 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)
This LED indicates a change of status or fault 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.
Drawer Fault LEDs (amber)
This LED indicates a disk, cable, or sideplane fault in the drawer indicate: Top (Drawer 0) or Bottom (Drawer 1).
