Module Polarisation/Keying.

All Trusted Modules have been keyed to prevent insertion into the wrong position within a chassis. The
polarisation comprises two parts. The module and the associated field cable.

Each module type has been keyed during manufacture. The organisation responsible for the
integration of the Trusted system must key the cable by removing the keying pieces from the cable so
that they correspond with the bungs fitted to the associated module prior to fitting.
