All Trusted Modules have been Keyed to help prevent insertion into the wrong
position within a Chassis. The polarization comprises two parts; the Module,
and the associated field cable.
Each Module type has been keyed during manufacture. The organization
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 that are fitted to the associated Module before fitting.

For Cables with Companion slot installations, both keying strips must be
polarized.
For this Module (T8461) remove keying pins 1, 5 and 7.
