2.1 Introduction
All SBU128 configuration options are software controlled, and settings
can easily be altered after the unit is installed in the system.
However the physical interface characteristics of the USER and LINK
ports are defined at manufacture by using separate pcb modules which
are not changeable except at the premises of your equipment supplier
and maintainer. They must only be changed by your supplier or
installation engineer.
WARNING. Access to the internal workings of your SBU128 is
strictly denied to all users, and may only be performed by
suitably qualified personnel. Any attempt to remove the outer
casing of your product will invalidate its approval.
