* The Power LED may continue to flash while a NetWare connection is being
established (if that option has been configured).
** The Line Sync LED will flash (two times a second for twinax or four times a
second for coax) until the attached twinax or 3270-coax printer is online and ready
to accept print jobs.
After this sequence is complete, the print server is ready for normal operation.
9.7 AS/400 Communication Trace
It may be necessary to capture a complete communications trace of data being
passed between the Ethernet to Twinax/Coax Print Server and the AS/400. This is
done by starting, ending, and printing a trace using IBM’s STRCMNTRC,
ENDCMNTRC, and PRTCMNTRC commands. See your IBM manuals for specific
instructions on using these commands.
9.8 Calling Black Box
If you determine that your Ethernet to Twinax/Coax Print Server is
malfunctioning, do not attempt to alter or repair it. It contains no user-serviceable
