8.1 Troubleshooting
The Diamond Storage Array provides a number of visual, audible and computer system-generated indicators to
identify the operational status of the array. 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 array, contact
technical support.
Windows 2000 special instructions
When using Windows 2000, the New Hardware
screen pops up and asks for a driver when the
Diamond Storage Array is first booted up. While
a driver is not necessary for operation, you should
install our dummy driver to eliminate the New
Hardware screen’s appearance. Download
AttoDM2k.zip from our website,
www.attotech.com, unzip it, and install the driver
AttoDM2k.inf according to the instructions in

• 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, provide 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 RS232 interface port or the optional Ethernet port.
The blink codes are also saved internally by the
array to NVRAM (Non Volatile Random Access
Memory) and are displayed at power up if the
power to the array is recycled.
