Product Overview
Lub Trusted® TMR Expander Processor Module nyob hauv lub processor slots ntawm Trusted Expander Chassis thiab muab ' qhev' interface ntawm Expander Bus thiab Expander Chassis Backplane. Lub Expander Bus tso cai rau ntau lub chassis siv los siv Unshielded Twisted Pair (UTP) cable txuas thaum tswj xyuas qhov ua txhaum cai, siab bandwidth Inter-Module Bus (IMB) muaj peev xwm.

Lub Module muab qhov yuam kev txwv rau Expander Bus, Module nws tus kheej thiab Expander
Chassis, xyuas kom meej tias cov kev cuam tshuam ntawm cov kev ua yuam kev no nyob hauv cheeb tsam thiab qhov system muaj ntau tshaj plaws. Lub Module yog qhov ua txhaum cai nrog HIFT TMR architecture. Kev tshuaj ntsuam xyuas, kev soj ntsuam thiab kev sim muab kev txheeb xyuas qhov yuam kev sai. Kub-standby thiab module spare
configurations tau txais kev txhawb nqa, tso cai tsis siv neeg thiab phau ntawv kho cov tswv yim Nta:

• Triple Modular Redundant (TMR), ua haujlwm tsis raug cai (3-2-0).
• Hardware Implemented Fault Tolerant (HIFT) architecture.
• Dedicated hardware and software test regimes uas muab ceev heev ua txhaum thiab
lub sij hawm teb.
• Tsis siv neeg ua txhaum cai yam tsis muaj teeb meem.
• Kub hloov.
• Pem hauv ntej vaj huam sib luag ntsuas uas qhia module noj qab haus huv thiab xwm txheej.

1.1. Txheej txheem cej luam
Lub TMR Expander Processor yog qhov ua txhaum kev tsim qauv raws li TMR architecture teem rau hauv lub xauv-kauj ruam configuration. Daim duab 1 qhia, hauv cov ntsiab lus yooj yim, cov qauv yooj yim ntawm TMR Expander Processor.
Lub Module muaj peb qhov kev txhaum loj hauv cheeb tsam (FCR A, B thiab C). Txhua lub FCRs tseem ceeb muaj qhov cuam tshuam rau Expander Bus thiab Inter-Module Bus (IMB), ib qho kev sib txuas ua haujlwm / standby rau lwm tus TMR Expander Processor hauv Chassis, tswj cov logic, kev sib txuas lus transceivers thiab cov khoom siv hluav taws xob.
Kev sib txuas lus ntawm Module thiab TMR Processor yog los ntawm TMR Expander Interface Module thiab triplicated Expander Bus. Lub Expander Bus yog triplicated, point-to-point architecture. Txhua channel ntawm Expander Bus muaj cais cov lus txib thiab cov lus teb xov xwm. Kev pov npav yog muab rau ntawm Expander Bus Interface los xyuas kom meej tias cable faults raug zam, thiab cov seem ntawm Expander Processor ua haujlwm nyob rau hauv tag nrho triplicated hom, txawm tias muaj teeb meem cable tshwm sim.
Kev sib txuas lus ntawm Module thiab I / O Modules hauv Expander Chassis yog los ntawm IMB ntawm Backplane ntawm Expander Chassis. Lub IMB zoo ib yam li ntawd nyob rau hauv lub Controller Chassis, muab tib lub txim txhaum, siab bandwidth kev sib txuas lus ntawm Interface Modules thiab TMR Processor. Raws li nrog Expander Bus Interface txhua qhov kev hloov pauv tau raug pov npav, qhov chaw ua txhaum cai rau IMB yog lawv tshwm sim.
Qhov thib plaub FCR (FCR D) muab cov kev saib xyuas tsis tseem ceeb thiab tso saib ua haujlwm thiab tseem yog ib feem ntawm kev pov npav inter-FCR Byzantine qauv.
Kev rho tawm yog muab los ntawm FCRs txhua qhov chaw uas yuav tsum tau muaj kev cuam tshuam, kom ntseeg tau tias qhov tsis raug tsis tuaj yeem nthuav tawm ntawm lawv.

1.2. Fais fab faib
TMR Expander Processor Module muab nws cov voltages sab hauv los ntawm dual redundant +24 Vdc fais fab mov los ntawm module connector los ntawm Trusted Expander Chassis Backplane. Txhua FCR muab cov khoom xav tau ntawm nws tus kheej.
