9.1 Troubleshooting
The Diamond-VT provides a number of indicators to identify the operational status of the array. System status
and error information is readily available. If your situation is not defined here or elsewhere in the manual, if these
solutions do not help, or if you have any questions or concerns about any aspect of operating the Diamond-VT,
contact technical support.
Windows 2000 special instructions
When using Windows 2000 and booting up the
Diamond-VT for the first time, the New Hardware
screen may ask for a driver. While a driver is not
necessary, install a dummy driver to eliminate the
screen’s appearance. Download
AttoDM2k.zip from
www.attotech.com , unzip it, and install the driver
according to the instructions in AttoDM2k.pdf .
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 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. The blink codes are
saved internally by the array to NVRAM and are
displayed at power up.
