Item Checks
Verify power presence and
characteristics On both the frame Network Controller Card and the 9363, 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 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 DashBoard™, red indications typically 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.
