This chapter explains how to isolate and solve problems
that may occur when you install the 3C509B NIC in a PC
running DOS, Windows 3.1, or Windows for Workgroups.
Checklist
If you experience problems installing the NIC, first check
these items:
■
Check the NIC LED, as described in “
Link LED
” on
page 25
.
■
Check the connectors. Examine the cable for obvious
signs of damage, wear, or crimping. Substitute a known
working cable.
■
Check whether the NIC software is correctly installed.
See
Chapter 4
.
■
Make sure the drivers installed are correct for the
network operating system you are running (see
“
Installing Other Supported Network Drivers
” on
page 84
).
If the problem persists, go to related procedures in this
chapter or see
Appendix C
, “
Technical Support
.”
Diagnostic Testing Under Windows 3.x
The Configuration and Diagnostics Program, on
EtherDisk
diskette 2, includes the diagnostics program
used for DOS, Windows 3.x, and Windows for
Workgroups. Run the diagnostic tests after installing
the 3C509B NIC to check overall NIC operation and to
isolate failures. After the NIC is installed, if the default tests
do not isolate the problem, tailor the test parameters to
accommodate your specific situation.
Do not run diagnostic tests with device drivers or memory
managers installed.
