Basic Trouble-Shooting:
Symptom Possible Solution
Cursor remains in the upper-right
corner of the session and then just
stays there, no sign-on screen.
This normally means that there is no physical connection to
the IBM host. Check that all wiring connections are secure
and snug. Check for bad connections or broken wires in the
Twinax or UTP cabling.
If UTP cabling is used, check that the two baluns are a
matching pair relative polarity and twisted pairs used.
Cursor moves to the upper left corner
of the session and then just stays
there, no sign-on screen.
This usually means that the LM-6488 is talking to the IBM
host at a base level, but there is something wrong in the
configuration parameters. Check that the Host Address you
used (0 through 6) is unique and that it is not a duplicate
used on another device attached to the IBM Host. Check
with your AS/400 administrator to determine the status of
this session at the IBM host.

NOTE:
Please do not reset the LM-6488 back to factory defaults or you will lose the Twinax
configurator. If for whatever reason, somebody resets the unit to factory defaults, please note
the following recovery procedure:
• Start-up Internet Explorer.
• At the address line, type in \hard disk (this is two words) and hit enter.
• Several file names will now appear, just double-click on “NLConfig”.
• This should then display a dialog box "Error - No command line”, just click OK and this
action will set-up the twinax configurator again.
• Now reboot the LM-6488, go to the Connection Manager, select the “Configure” tab and
then click on “Add” at the bottom left-hand corner. From the “New Selections” panel
scroll through the options and the selection “NLynx Twinax Emulation” should be there.
You are now good to go again.
