Each field's values should be increasing if the TN230X is
actively sending and receiving cells with the A500. (Even if
a TN230X did not achieve board insertion, it will still try to
talk to the A500.)
If neither field is increasing, the A500 port may have been
marked down using the admin down command. Use the

The error counters may not be zero, but should not be large
