Troubleshooting
Testing the Accessory Slot and I/O Connections
When you are sure that the computer is operating properly, test the
computer accessory slot and I/O connections using another DAS-1800HC
Series board that you know is functional. To test the computer accessory
slot and the I/O connections, follow these steps:
1. Remove computer power again, and install a DAS-1800HC Series
board that you know is functional. Do not make any I/O connections.
2. Turn computer power ON and check operation with the functional
board in place. This test checks the computer accessory slot. If you
were using more than one DAS-1800HC Series board when the
problem occurred, use the functional board to test the other slot, as
well.
3. If the accessory slots are functional, use the functional board to check
the I/O connections. Reconnect and check the operation of the I/O
connections, one at a time.
4. If operation fails for an I/O connection, check the individual inputs
one at a time for shorts and opens.
5. If operation remains normal to this point, the problem is in the
DAS-1800HC Series board originally in the computer. If you were
using more than one board, try each board one at a time in the
computer to determine which is faulty.
6. If you cannot isolate the problem, refer to the next section for
instructions on obtaining assistance.
