Unit identification (UID) button
The unit identification (UID) button helps locate an enclosure and its components. When the UID button
is activated, the UID on the front and rear of the enclosure are illuminated.
NOTE:
A remote session from the management utility can also illuminate the UID.
• To turn on the UID light, press the UID button. The UID light on the front and the rear of the enclosure
will illuminate solid blue. (The UID on cascaded storage enclosures are not illuminated.)
• To turn off an illuminated UID light, press the UID button. The UID light on the front and the rear
of the enclosure will turn off.
Power supply module
Two power supplies provide the necessary operating voltages to all controller enclosure components.
If one power supply fails, the remaining power supply is capable of operating the enclosure. (Replace
any failed component as soon as possible.)
NOTE:
If one of the two power supply modules fails, it can be hot-replaced.
Power supply LED
One LED provides module status information.
