1.3. Bus Terminations
The backplane contains termination circuits for certain bus signals. The terminators are used to
reduce signal reflections on critical signals and also to provide default logic levels for open or tri-stated
signals. Termination circuits are located at the end slot positions, 1 and 14.
1.4. Bus Connections
All bus connections are triplicated except for the +24V dc external power supply, which is dual
redundant.

The module positions for the Trusted
TM
Expander Processors are pre-configured and may only be

connector. The male connector is on the backplane.
