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.

•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.
