Basic Troubleshooting Checks
Failures of a general nature (affecting many cards and/or functions
simultaneously), or gross inoperability errors are best addressed first by
performing basic checks before proceeding further. Table 3-4 provides basic
system checks that typically locate the source of most general problems. If
required and applicable, perform further troubleshooting in accordance with
the other troubleshooting tables in this section.
Table 3-4 Basic Troubleshooting Checks
Item Checks
Verify power presence and
characteristics • On both the frame Network Controller Card and the 9084, in all cases when power is
being properly supplied there is always at least one indicator illuminated. Any card
showing no illuminated indicators should be cause for concern.
• Check the Power Consumed indications for both the +12 V and -7.5 V supply rails
for the 9084 card. This can be observed using the DashBoard™ Card Info pane, or
using the card edge controls and indicators as shown in Figure 3-4 on page 3-7.
• If either of the rail supplies show no power being consumed, either the frame
power supply, connections, or the 9084 card itself is defective.
• If either of the rail supplies show excessive power being consumed (see
Technical Specifications (p. 1-11) in Chapter 1, “Introduction”), the 9084 card
may be defective.
Check Cable connection
secureness and connecting
points Make certain all cable connections are fully secure (including coaxial cable attachment
to cable ferrules on BNC connectors). Also, make certain all connecting points are as
intended. Make certain the selected connecting points correlate to the intended card
inputs and/or outputs. Cabling mistakes are especially easy to make when working
with large I/O modules.
Card seating within slots Make certain all cards are properly seated within its frame slot. (It is best to assure
proper seating by ejecting the card and reseating it again.)
Check status indicators and
displays On both DashBoard™ and the 9084 card edge indicators, red indications signify an
error condition. If a status indicator signifies an error, proceed to the following tables in
this section for further action.
Troubleshoot by substitution All cards within the frame can be hot-swapped, replacing a suspect card or module
with a known-good item.
