5-10 Troubleshooting KPCI-PIO32IOA and KPCI-PDISO8A User’s Manual
26. Determine which original board has faulty I/O. If the faulty board survived the PCI resource
test in step 25, it should fail the I/O test.
a. If an original board remains installed following step 25, then skip to step 26e.
b. Turn OFF the computer.
c. Install one of the original boards in a slot known to be satisfactory.
d. Turn ON the computer.
e. Perform the test outlined in the “I/O test” subsection. Then return to this step (26e).
f. Based on the results of step 26e, do one of the following:
• If, in step 26e, you cannot write and read all I/O bits to and from the first original
KPCI-PIO32IOA or KPCI-PDISO8A board that you test, you have located the faulty
board; replace it with the OK board. (To repair the faulty board or obtain a new one,
contact Keithley as described in “
Technical support .”) Then skip to step 27.
• If, in step 26e, you can write and read all I/O bits to and from the first original board
that you test, repeat steps 26b through 26e for additional original KPCI-PIO32IOA
and KPCI-PDISO8A boards until you find a faulty board. Replace the faulty board
with the OK board. (To repair the faulty board or obtain a new one, contact Keithley
as described in “
Technical support .”) Then continue with step 27.
• However, if you have reached this point after trying all original boards, and the I/O on
each board has been found satisfactory, then the cause of your problem may be out-
side the scope of these diagnostics. Read the instructions in “
Technical support ,” and
contact Keithley for help in isolating the cause of your problem.
27. Assuming the problem has been resolved, do the following:
a. Turn OFF the computer.
b. Install the good KPCI-PIO32IOA and KPCI-PDISO8A boards in good slots.
c. Reinstall the computer cover.
d. Reconnect all external circuits as discussed in Section 3 , “ Installation .”
e. Turn ON the computer.
f. Verify that the system now performs satisfactorily.
28. Based on the results of step 27f, select one of the following:
•
If the system now performs satisfactorily, you have successfully isolated and corrected
the problem.
•
If the system still does not perform satisfactorily, then the cause of your problem may be
outside the scope of these diagnostics. Read the instructions in “
Technical support ,” and
then contact Keithley for help in isolating the cause of your problem.
