3 Troubleshooting

3-68 9901-UDX PRODUCT MANUAL 9901-UDX-OM (V1.15)

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 3-3 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.

9901-UDX Processing Error Troubleshooting

Table 3-4 provides 9901-UDX processing troubleshooting information. If the

9901-UDX 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

9901-UDX is not appropriately set for the type of signal being received by the

card.

Note: The error indications shown below are typical for the corresponding error con-

ditions listed. Other error indications not specified here may also be displayed

on DashBoard™ and/or the 9901-UDX card edge status indicators.

Note: Where errors are displayed on both the 9901-UDX card and network remote

controls, the respective indicators and displays are individually described in

this section.

Table 3-3 Basic Troubleshooting Checks

Item Checks

Verify for power presence On both the frame Network Controller Card and the 9901-UDX, 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 both DashBoard™ and the 9901-UDX 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.
