Figure 7-1 Adapter LEDs
When lit, the green LED (labeled “4”) indicates that the adapter
is set to 4 Mbps speed and is correctly inserted into the ring.
When lit, the yellow LED (labeled “16”) indicates that the adapter

Using the TokenDisk Diskette Diagnostic Program
Run the TokenDisk diskette Configuration and Diagnostic
Program for your installed 3C619C adapter when you need to
do the following:
■ Test for setup/configuration
■ Test for physical board problems
■ View adapter statistics
The diagnostic program tests the adapter, not the network.
Make sure to boot from DOS before running the diagnostic
program because the TokenDisk diskette is not a bootable disk.
Make sure that your PC has an 80386 or higher processor.
The 3C619C adapter must be connected to the network for all
tests.
