T8270 Trusted Fan Tray (Chassis)

This document provides general information for the Trusted® Processor Interface Adapter T812X. The Adapter provides easy access to the communications ports of the Trusted Triple Modular Redundant (TMR) Processor (T8110B & T8111) in the Controller Chassis for the Distributed Control System (DCS) and other links. The unit is also used to enable a number of extended facilities available on the Trusted TMR Processor including facilities for the reception of IRIG-B time synchronisation signals, enabling the use of Dual (‘enhanced’) Peer to Peer and enabling the Trusted System to become MODBUS Master.

The migration principles are identical for Regent (panel mount) and Regent +Plus (rack mount) because the internal circuitry is the same, as is the software. In this document, the term ‘Regent’ is used for both variants. The Regent processor chassis with processor and communications modules is replaced by a Trusted processor chassis with communications modules. The T8160 TMR Interface module (otherwise known as the Regent interface module, or RIM) bridges the triplicated Regent Safetybus into the Trusted Inter-Module Bus (IMB). The T8160 has a choice of two companion slot cables TC-320-01 and TC321-01. TC-320-01 ends in three connectors that fit the Regent chassis sockets. TC-321-01 ends in three connectors that fit the existing Safetybus cables. This allows a choice of running new cables to the first expander chassis or using the extra length of the existing cables. The Trusted processor chassis is 6U high but also needs a 2U T8270 fan tray mounted above it. It should not be located directly above bulk power supplies or other significant sources of heat, as air is drawn from underneath the chassis. A Trusted system requires one T8110B processor module (which contains three identical processors). The chassis also has a companion processor slot to allow faulty processors to be replaced. For a Trusted-Regent hybrid, one T8160 TMR interface module is required, and this is also fitted in a companion slot, taking two of the eight single width slots. To replace the three Regent communications modules, two Trusted T8151B communication interface modules are adequate. These each contain four high speed serial ports and also two Ethernet ports. They support Modbus (master and slave) and native Trusted peer networks, but will not support Regent Peer to Peer networks or the Regent Guarded Peer link. Modbus Master requires a T8122 or T8123 Processor interface adapter.
