Off: system not operating regardless of AC present
2 Status/Health
Constant blue: system is powered on and controller is ready
Blinking blue (2 Hz): Enclosure management is busy
Constant amber: module fault present
Blinking amber: logical fault (2 seconds on, 1 second off)
3 Unit identification display (UID) Green (seven-segment display: enclosure sequence)
4 Identity

Off: Normal state
System power LED (green)
LED displays green when system power is available. LED is off when system is not operating.
Status/Health LED (blue/amber)
LED illuminates constant blue when the system is powered on and functioning normally. LED blinks blue when enclosure management is
busy, for example, when booting or performing a firmware update. LEDs helps you identify which component is causing the fault. LED
illuminates constant amber when experiencing a system hardware fault which could be associated with a Fault LED on a controller module,
IOM, or PCM. LED illuminates blinking amber when experiencing a logical fault.
Unit identification display (green)
The UID is a dual seven-segment display that shows the numerical position of the enclosure in the cabling sequence. This is also called the
enclosure ID. The controller enclosure ID is 0.
Identity LED (blue)
When activated, the Identity LED blinks at a rate of 1 second on, 1 second off to easily locate the chassis within a data center. The locate
function can be enabled or disabled through SES. Pressing the button toggles the state of the LED. Setting the enclosure ID using the
System ID button is not supported by the firmware.
5U enclosure Ops panel
The front of the enclosure has an Ops panel located on the left ear flange of the 5U chassis.
The Ops panel is an integral part of the enclosure chassis, but is not replaceable on site.
