Interpret system LEDs

Visual cues 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 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. Flashing green or amber LED: Indicates a non-critical condition
3. Amber LED: Indicates a critical fault
4. Blue LED: Indicates system component identification, so is not a fault or critical condition
Since an amber fault LED uses fast or slow flashes to cover multiple conditions, this is the priority for simultaneous indications:

Table 4 Fault LED prioritization

Priority Flash rate
Top priority Fast flash (1s on, 1s off)
Priority 2 On
Priority 3 Slow flash (3s on, 1s off)
Lowest priority Off
The front panel area, controller module, and expansion module LEDs require further elaboration.

Interpret 5U enclosure operator's panel LEDs

The storage enclosure operator's (ops) panel contains a series of LEDs to reflect system status. You can monitor the ops 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. Refer to the
baseboard management controller (BMC) system event log (SEL) for detailed information.
