Figure 1 Trusted TM Expander Chassis and Backplane
The Chassis may be populated in different ways dependent on the requirements of each System, to
accommodate a maximum of 12 single-width (30mm) Trusted

I/O Modules and up to two single-
width Trusted

Expander Processors. The Chassis assembly has eight screw positions, four on each
flange, that are used to enable secure attachment to the side brackets on the frame.
Modules are inserted by sliding them carefully into their slot position, ensuring that the ‘U’-channels of
the module top and bottom casings engage the raised guides of the upper and lower chassis plates.
Ejector levers on the modules secure the handle-less modules within the chassis.
A 90mm space must be provided between chassis on a frame to assist the cooling process.
