Error Messages

System Fault LED
If a serious hardware or software
error occurs in the Diamond-VT, the
System Fault
LED
will display a series of flashes or blink codes.
• an initial series of blinks indicate a system
problem
• a two second pause
• another series of blinks providing more detailed
information for technical personnel.
• a four-second pause
• sequence repetition from step 1 until the error is
cleared.
In general, any fault will require notification of
Diamond Array technical personnel for resolution or
for further debug instructions. When you report an
error code, please provide both the first and se cond
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. The blink codes are
saved internally by the array to NVRAM and are
displayed at power up.
