Power Supply Monitoring
The array monitors the

assemblies every 30 seconds. If the status
changes, the system reports it visually with an
LED and a message in the CLI.

System Fault LED and Error Codes
If a serious
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.

Fault LED flashes repeatedly in a blink code
pattern:
• an initial series of blinks indicating the system
problem
• 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.
