Problem isolation
If you encounter a problem with a KPCI-3110 or KPCI-3116 board, perform the following steps
to determine whether the problem is in the computer, in the KPCI-3110 or KPCI-3116 board, or
in the I/O circuitry:
1. Remove power connections to the host computer.
2. Unplug the accessory connector(s) or cable(s) from the KPCI-3110 or KPCI-3116 board(s),
keeping the connections intact on the accessory or expansion board(s).
3. Remove the KPCI-3110 or KPCI-3116 board(s) from the computer and visually check for
damage. If a board is obviously damaged, refer to page 6-7 for information on returning the
board.
4. With the KPCI-3110 or KPCI-3116 board(s) out of the computer, check the computer for
proper operation. Power up the computer and perform any necessary diagnostics.
5. When you are sure that the computer is operating properly, remove computer power again,
and install a KPCI-3110 or KPCI-3116 board that you know is functional. Do not make any
I/O connections.
6. Apply computer power and check operation with the functional KPCI-3110 or KPCI-3116
board in place. This test checks the computer accessory slot. If you are using more than one
KPCI-3110 or KPCI-3116 board, check the other slots you are using.
7. If the accessory slots are functional, check the I/O hookups. Connect the accessory and
expansion boards, one at a time, and check operation.
8. If operation is normal, the problem is in the KPCI-3110 or KPCI-3116 board(s) originally in
the computer. Try the KPCI-3110 or KPCI-3116 board(s) one at a time in the computer to
determine which is faulty. Use the troubleshooting information in the next section to try to
isolate the problem.
9. If you cannot isolate the problem using the general instructions here, refer to Appendix C ,
“ Systematic Problem Isolation ” for a more detailed problem isolation scheme.
10. If you cannot isolate the problem after further investigation, refer to page 6-6 for instructions
on getting technical support.
