6–4 • Troubleshooting HDC-8223A(-S) User Manual (Iss. 03)
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 6.2 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 chapter.
Table 6.2 Basic Troubleshooting Checks
Item Checks
Verify power presence and
characteristics
On both the frame Network Controller Card and the HDC-8223A(-S), 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 HDC-8223A(-S) 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 HDC-8223A(-S) card itself is defective.
• If display shows excessive power being consumed (refer to the chapter
“ Specifications ” on page 7-1), the HDC-8223A(-S) 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 rear 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 HDC-8223A(-S) 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.
