KPCI-PIO24 User’s Manual Troubleshooting 5-3
If your board is not operating properly after using the information in Table 5-1, continue with the
next section to further isolate the problem.
Systematic problem isolation
General problem isolation procedure
If you were unable to isolate the problem using Table 5-1, then follow Figure 5-1 and the
accompanying written procedure. The flowchart in Figure 5-1 summarizes how to systematically
check and eliminate some problem causes. The corresponding written procedure amplifies the
flowchart steps with more detail.
CAUTION Always turn OFF your computer and any external circuits
connected to the KPCI-PIO24 board before removing or
replacing the board. Removing or replacing a board with the
power ON can damage the board, the computer, the external
circuit, or all three.
Handle the board at the mounting bracket, using a grounded
wrist strap. Do not touch the circuit traces or connector contacts.
If you do not have a grounded wrist strap, periodically discharge
static electricity by placing one hand firmly on a grounded metal
portion of the computer chassis.
NOTE In the following procedure, the term “board” always refers to a
KPCI-PIO24 board. The procedure never directs you to install or
remove any type of PCI board other than a KPCI-PIO24 board.
In Figure 5-1 the number in brackets in each flowchart block (e.g
. [21]
)
refers to the corresponding step number in the verbal procedure. If
multiple blocks in the flowchart have the same number, each of those
blocks is part of a single verbal step. Conversely, if there is a range of
numbers in the brackets (e.g.
[4, 5, 6]
), the block summarizes multiple
verbal steps.
The logic in this procedure assumes that the problem has only one
cause. Therefore, once a cause is found and corrected, the reader is
instructed to reassemble the system and verify proper operation.
