2.5. Trusted Module Polarisation/Keying

All Trusted Modules have been Keyed to help 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.
