5U84 enclosure LEDs
When the 5U84 enclosure is powered on, all LEDs turn on for a short period to ensure that they are working.
NOTE:
This behavior does not indicate a fault unless LEDs remain lit after several seconds.
5U enclosure Ops panel
The front of the enclosure has an Ops panel that is located on the left ear flange of the 5U chassis. The Ops panel is part of the
enclosure chassis, but is not replaceable on-site.

Indicator
Description
Color
Status
Unit Identification
Display (UID)
Green
Dual seven-segment display that shows the numerical position of the
enclosure in the cabling sequence. The UID is also called the enclosure ID.
The controller enclosure ID is 0.
System Power On/
Standby
Green
On steady: system power is available (operational)
Amber
Constant amber: system in standby (not operational)
Module Fault
Amber
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.
