Problem Isolation
7-5
Testing the Board and Host Computer
To isolate the problem to the DAS-1800ST/HR Series board or to the host
computer, use the following steps:
Caution:
Removing a board with the power ON can cause damage to
your board and/or computer.
1. Turn the power to the host computer OFF, and remove power
connections to the computer.
2. While keeping connections to accessories intact, unplug the cable to
the main I/O connector of the DAS-1800ST/HR Series board.
3. Remove the board from the computer and visually check for damage.
If a board is obviously damaged, refer to “Technical Support” on page
7-6 for information on returning the board.
4. With the DAS-1800ST/HR Series board out of the computer, check
the computer for proper operation. Power up the computer and
perform any necessary diagnostics.
At this point, if you have another DAS-1800ST/HR Series board that you
know is functional, you can test the slot and I/O connections using the
instructions in the next section. If you do not have another board, refer to
the instructions on page 7-6 before calling Keithley for technical support.
