Zowonetsa Zamalonda
Trusted® TMR Expander Processor Module imakhala m'malo opangira pulosesa ya Trusted Expander Chassis ndipo imapereka mawonekedwe a 'kapolo' pakati pa Expander Bus ndi Expander Chassis Backplane. Mabasi a Expander amalola makina angapo a chassis kuti akhazikitsidwe pogwiritsa ntchito ma chingwe a Unshielded Twisted Pair (UTP) ndikusunga mphamvu zololera zolakwika, bandwidth yapamwamba ya Inter-Module Bus (IMB).

Moduleyo imapereka zosungira zolakwika za Expander Bus, Module yokha ndi Expander
Chassis, kuwonetsetsa kuti zotsatira za zolakwika zomwe zingachitike ndizokhazikika komanso kupezeka kwadongosolo kumachulukira. Module ndi yololera zolakwika ndi zomangamanga za HIFT TMR. Kuwunika kokwanira, kuyang'anira ndi kuyezetsa kumapereka chidziwitso chofulumira. Hot-standby ndi module spare
masinthidwe amathandizidwa, kulola njira zodzikonzera zokha komanso pamanja Zina:

• Katatu Modular Redundant (TMR), kulekerera zolakwika (3-2-0).
• Zomangamanga za Hardware Implemented Fault Tolerant (HIFT).
• Hardware odzipereka ndi mapulogalamu mayeso boma amene amapereka mofulumira kwambiri kuzindikira zolakwika ndi
nthawi zoyankhira.
• Kusamalira zolakwika zokha popanda vuto lowopsa.
• M'malo otentha.
• Zizindikiro za Front Panel zomwe zimawonetsa thanzi la gawo ndi momwe alili.

1.1. Mwachidule
The TMR Expander Processor ndi kapangidwe kolekerera zolakwika kutengera kamangidwe ka TMR kokonzedwa motsatira loko. Chithunzi 1 chikuwonetsa, m'mawu osavuta, kapangidwe kake ka TMR Expander processor.
Module ili ndi zigawo zazikulu zitatu zosungira zolakwika (FCR A, B ndi C). Iliyonse mwa ma FCR akuluakulu imakhala ndi zolumikizira ku Expander Bus ndi Inter-Module Bus (IMB), mawonekedwe okhazikika / oyimilira ku TMR Expander processor ina mu Chassis, malingaliro owongolera, ma transceivers olumikizirana ndi zida zamagetsi.
Kulankhulana pakati pa Module ndi TMR Processor kukuchitika kudzera pa TMR Expander Interface Module ndi Bus ya Expander yopangidwa katatu. Mabasi a Expander ali ndi magawo atatu, mamangidwe a point-to-point. Njira iliyonse ya Expander Bus imakhala ndi malamulo osiyana ndi mayankho. Kuvota kumaperekedwa pa Expander Bus Interface kuti zitsimikizidwe kuti zolakwika za chingwe zimaloledwa, ndipo chotsalira cha Expander Processor chimagwira ntchito motsatizana katatu, ngakhale pakakhala vuto la chingwe.
Kulankhulana pakati pa Module ndi Ma I/O Module mu Expander Chassis ndi kudzera pa IMB pa Backplane ya Expander Chassis. IMB ndiyofanana ndi yomwe ili mkati mwa Controller Chassis, yopereka zololera zomwezo, kulumikizana kwakukulu kwa bandwidth pakati pa Interface Modules ndi TMR processor. Monga momwe zilili ndi Expander Bus Interface zochitika zonse zimavoteledwa, kuyika zolakwika ku IMB zikachitika.
FCR yachinayi (FCR D) imapereka ntchito zowunikira komanso zowonetsera zosafunikira komanso ndi gawo la mavoti apakati pa FCR Byzantine.
Kudzipatula kumaperekedwa pakati pa ma FCR kulikonse komwe kungafunike, kuwonetsetsa kuti zolakwika sizingafalikire pakati pawo.

1.2. Kugawa Mphamvu
TMR Expander Processor Module imatenga ma voltages ake amkati kuchokera ku mphamvu ziwiri zosafunikira +24 Vdc zomwe zimaperekedwa kudzera pa cholumikizira cha module kuchokera ku Trusted Expander Chassis Backplane. FCR iliyonse imapeza zofunikira paokha.
