Title: Jumper Fix for 3S/50x Servers Upgraded From Beta Units
Date: 12/5/89

Copyright 3Com Corporation, 1991.  All rights reserved.

Beta units of 3S/500-series servers had the external transceiver
DIX jumper labeled as J2.  The production version has the DIX jumper
labeled as J3.  The jumper must be set correctly or no packets will be
transmitted to the transceiver.

If you have a server that was upgraded from beta to production level,
and it is using an external transceiver, make sure the J3 jumper is
toggled toward the back of the unit.  (Note:  You will only have an
upgraded server if you participated in beta testing of the product.)
