IMPORTANT The storage enclosure design requires two redundant power supply units (PSUs). You must plug
each power cord into an independent power distribution unit (PDU) that connects to an uninterruptible power
system.

2. Facing the front, observe the LEDs on the front panel and confirm the System power LED is in a steady green state.
3. When you are ready to power down the storage enclosure, disconnect the right-angle power connector from both
PSUs.

Interpret system LEDs

Visual cues, such as the LEDs, provide you with the means to monitor the storage enclosure and its components and
reinforce software messages about system health. Use LEDs throughout the storage enclosure as a means to determine
if there is a critical fault.
The storage enclosure registers the following states using the identified LED colors.
1. Green or unlit LED: Indicates a module is functioning normally
2. Blinking green or amber LED: Indicates a non-critical condition
3. Amber LED: Indicates a critical fault
4. Blue LED: Indicates system component identification, not a fault or critical condition
The front panel and the controller module LEDs require further elaboration, so each have their own section.

Interpret front panel LEDs

The storage enclosure front panel contains a series of LEDs to reflect system status. You can monitor the front panel
LEDs to determine system status in combination with the user interface content.
In the case of a system fault condition, identified in the state column with an asterisk (*), troubleshoot the fault.
