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 3-2 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.
9284 Processing Error Troubleshooting
Table 3-3 provides card processing troubleshooting information. If the card
exhibits any of the symptoms listed in Table 3-3, follow the troubleshooting
instructions provided.
In the majority of cases, most errors are caused by simple errors where the
card is not appropriately set for the type of signal being received by the card.
Note: If alarms are not enabled on the card, loss of signal and other signal alarms
may not be reported by the card DashBoard™ Card Info pane. (See I/O Set-
tings (p. 3-12).

Item Checks
Verify power presence and
characteristics • On both the frame Network Controller Card and the 9284, 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 indication for the 9284 card. This can be observed
using the DashBoard™ Card Info pane.
• If no power is being consumed, either the frame power supply, connections, or
the 9284 card itself is defective.
• If excessive power is being consumed (see Technical Specifications (p. 1-22) in
Chapter 1, “Introduction”), the 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 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.
