9934-AUD-PRO-DSP Processing Error Troubleshooting
9934-AUDPRO-OM (V1.5)
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 3-3 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.
• On both the frame Network Controller Card and the 9934-AUD-PRO-DSP,
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 9934-AUD-PRO-DSP card.
This can be observed using the DashBoard™ Card Info pane.
• If display shows no power being consumed, either the frame power
supply, connections, or the 9934-AUD-PRO-DSP card itself is
defective.
• If display shows excessive power being consumed (see Technical
Specifications (p. 1-20) in Chapter 1, "Introduction"), the
9934-AUD-PRO-DSP card may be defective.
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.
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.)
On both DashBoard™ and the 9934-AUD-PRO-DSP 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.
All cards within the frame can be hot-swapped, replacing a suspect card or
module with a known-good item.
Table 3-4 provides 9934-AUD-PRO-DSP processing troubleshooting
information. If the 9934-AUD-PRO-DSP card exhibits any of the symptoms
listed in Table 3-4, follow the troubleshooting instructions provided. In the
majority of cases, most errors are caused by simple errors where the
9934-AUD-PRO-DSP is not appropriately set for the type of signal being
received by the card.
