Power Supply Monitoring
operation of its power supplies and blower
assemblies every 30 seconds. If the status
changes, the system reports it visually with an
LED and a message in the CLI.
If a power supply or blower fails, the management
system sends a CLI message and turns off the
corresponding power supply LED.
The blower assembly directly adjacent a power
supply must be functioning properly for the power
supply to work properly. If a blower assembly
fails, the power supply shuts down and the
management system sends a CLI message. The
corresponding power supply LED on the system
management card also turns off.
If a good replacement power supply or blower
assembly is inserted into the array, the
management system sends a CLI message and the
corresponding system management card LED
lights. It may take up to 30 seconds for the system
to note these changes.
System Fault LED and Error Codes
hardware or software error occurs in the array, the
System Fault LED displays a series of flashes or
blink codes. Error information is reported via the
CLI if it is operational.
At power up, the green array Ready (RDY) LED
turns on after successful completion of the POST
(Power On Self Test) indicating the array is
available for normal operation.

During operation, the Ready LED stays lit even if
the amber Fault (FLT) LED lights.
If a serious error occurs in the array, the amber
Fault LED flashes repeatedly in a blink code
pattern:
• an initial series of blinks indicating the system

• a two second pause
• another series of blinks providing more detailed
information for technical personnel.
• a four-second pause
• the blink code sequence repeats from step 1
until the error is cleared.
In general, any fault requires notification of
Diamond Storage Array technical personnel for
resolution or for further debug instructions. When
you report an error code, please provide both the
first and second blink code values.
During a fault condition, more detailed
information about the fault may be available via
the CLI or the ExpressNAV interface over the RS-
232 interface port or the optional Ethernet port.
