Troubleshooting

 

Testing Accessory Slot and I/O Connections

 

To determine whether the problem is in the accessory slot or in the I/O 
connections, perform the following steps:

1. When you are sure that the computer is operating properly, remove 

computer power again, and install a DDA-08/16 board that you know 
is functional. Do not make any I/O connections.

2. Apply computer power and check operation with the functional 

DDA-08/16 board in place. This test checks the computer accessory 
slot. If you are using more than one DDA-08/16 board, check the 
other slots you are using.

3. If the accessory slots are functional, check the I/O connections. 

Connect the accessory boards, one at a time, and check operation.

4. If operation is normal, the problem is in the DDA-08/16 board(s) 

originally in the computer. Try the DDA-08/16 board(s) one at a time 
in the computer to determine which is faulty. 

5. If you cannot isolate the problem, refer to the next section for 

instructions on getting technical support.
