2.5. Trusted TM Module Polarisation/Keying.
All Trusted TM 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
TM 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.
