DESCRIPTION

The Trusted

TMR Expander Processor

module resides in the processor slots of the

Trusted

Expander Chassis and provides the

‘slave’ interface between the Expansion Bus

and the Expander Chassis backplane. The

Expander Bus allows multiple chassis systems

to be implemented using UTP cable

connections whilst maintaining the fault

tolerant, high bandwidth Inter-Module Bus

(IMB) capabilities.

The module provides fault containment

for the expander bus, the module itself

and the expander chassis, ensuring that

the effects of these potential faults are

localised and system availability

maximised. The module is fault tolerant

with Hardware Implemented Fault

Tolerant (HIFT), Triple Modular

Redundant (TMR) architecture.

Comprehensive diagnostics, monitoring

and testing provide rapid fault

identification. Hot standby and module

spareing configurations are supported,

allowing automatic and manual repair

strategies.

Communication between the Expander

Processor and the TMR Processor is via

the TMR Expander Interface Module

and the triplicated Expander Bus. The

Expander Bus is triplicated, point-to-

point architecture. Each channel of the

Expander Bus comprises separate

command and response media. Voting

is provided at the Expander Bus

Interface to ensure that cable faults are

tolerated, and the remainder of the

Expander Processor operates in a fully

triplicated mode, even in case of cable

faults occurring.

Communication between the Expander

Processor and the I/O modules in the

Expander Chassis is via the IMB on the

backplane of the Expander Chassis.

The IMB is identical to that within the

Controller Chassis, providing the same

fault tolerant, high bandwidth

communications between the interface

modules and the TMR Processor. As

with the Expander Bus Interface all

transactions are voted, localising faults

to Fault Containment Region (FCR)

within the IMB should they occur.

The TMR Expander Processor Module

derives its internal voltages from dual

redundant +24V dc power supplied via

the module connector from the

Trusted

Expander Chassis backplane.

Each FCR derives the required supplies

independently.

Non-critical monitoring

and module status display

functions (front panel

LEDs) are also provided.
