IBM 3270 Network Card User Manual


 
If your system has a battery unit:
“Warning: Do not dispose of the battery unit in fire or water.
See instructions for disposal in the battery installation
instructions.”
“Check the condition of the battery.”
Problem Isolation
All repair action associated with the card begins here.
Problem isolation is based on operator-reported failures or diagnostic
messages. These procedures point out system unit problems,
cabling, and card problems.
If the failure is not caused by the card, go to the maintenance
packages for other options, if installed. If the problem is still not
resolved, refer to the hardware maintenance manual for the personal
computer being serviced.
To do problem isolation, you need the 3270 PCI Card diagnostic
utility that is on the CD-ROM shipped with the card and the hardware
maintenance manual for the personal computer being serviced.
Follow the “Problem Determination Procedures” on page 14 to
determine whether or not the 3270 PCI card is bad.
Additional Problem Isolation
If you have completed problem isolation procedures without solving
the problem, the following steps should help you find additional audio
or visual symptoms.
1. Check the entire system for loose or damaged connectors.
2. Go to the hardware maintenance manual for the personal
computer and follow the procedures there.
If you have followed these procedures and still have an unsolved
problem, you should request technical assistance (see Appendix A
on page 23).
