Ku vuyisela Sun SPARCstation IPX xiphemu xa 1: PSU na NVRAM (2020) .

Ntlhantlho a wu katsa ku desolder hi vukheta chip ya khale ya NVRAM no yi siva hi leyintshwa, leyi a yi sunguriwile ka ha ri emahlweni hi swiyimiso leswinene hi ku tirhisa muendli wa tiprogreme wa manguva lawa. Handle ka sweswo, ku nga nghenisiwa sokheti leswaku swi olova enkarhini lowu taka. Loko NVRAM leyintshwa yi ri kona, SPARCstation IPX yi hetelele yi hetile POST ya yona (Power-On Self-Test), yi kombisa logo ya Sun ya xifaniso eka xikirini. A ku ri nkarhi wa ku hlula—muchini wu vuyeleriwile.

Masungulo ya Vumundzuku

Ku vuyisela PSU na NVRAM swi vuyisele IPX leyi ya SPARCstation ku suka emakumu. Sweswi yi na masungulo lama tiyeke lawa yi ma lavaka ku ya emahlweni eka switeji leswi landzelaka: vukamberi bya hardware, ku cinciwa ka drive ya SCSI, naswona eku heteleleni, ku nghenisa sisiteme yo tirha ya Solaris. Endlelo leri ri kandziyisa dyondzo ya nkoka eka sisiteme yihi na yihi, ya khale kumbe leyintshwa. Tanihi leswi Mewayz yi nyikaka xisekelo xa modula, lexi tshembekaka lexi mabindzu ya nga aka na ku pfumelelana na xona, masungulo ya hardware lama vuyeleriweke hi ndlela leyi humelelaka ya pfumelela muchini lowu wa matimu ku tirha nakambe. Eka Xiphemu xa 2, hi ta nghenelela eka sisiteme ya le hansi ya vuhlayiselo na mintlhontlho yo tisa sisiteme yo tirha ya malembe ya 30 eka inthanete.

Swivutiso Leswi Vutisiwaka Nkarhi Na Nkarhi

Ku vuyisela Sun SPARCstation IPX: Riendzo ro Vuyela eka 1991

Emisaveni leyi fambaka hi rivilo ra mabindzu ya manguva lawa, laha hi lwelaka tipulatifomo ta modular, leti nga ringanisiwaka to fana na Mewayz, ku na nkoka wo hlawuleka eka ku languta endzhaku eka masungulo ya khomphyuta ya switichi swa ntirho. Sun SPARCstation IPX, leyi humesiweke hi 1991, a yi ri xihlamariso xa nkarhi wa yona—muchini lowu a wu nyika matimba eka tilaboratori ta vunjhiniyara, ndzavisiso wa sayense ni ku endla tisoftware. Ku vuyisa nchumu wo tano lowu saleke evuton’wini a hi ku titoloveta ka vutshila ntsena; i dyondzo ya ku tiyisela, dizayini, na xilaveko lexi nga heriki xa tisisiteme leti akiweke leswaku ti tshama nkarhi wo leha. Riendzo leri ro vuyisela, ku sungula hi swiphemu swa nkoka swa Mphakelo wa Gezi na NVRAM, ri kombisa filosofi ya Mewayz: sisiteme leyi humelelaka, hambi ku ri xitichi xa ntirho xa malembe ya 30 kumbe OS ya bindzu ya manguva lawa, yi titshege hi masungulo lama tiyeke, lama tshembekaka.

Muvabyi: IPX ya Sun SPARCstation

Ku koka chassis leyi nga na ritshuri, ya beige kusuka eka sirha ra yona ro hlayisa i goza ro sungula. SPARCstation IPX, na dizayini ya yona yo hlawuleka ya "lunchbox", yi ringanile hi ndlela yo hlamarisa. Yuniti leyi yo karhi a yi nga hlamuli nikatsongo—mhaka ya xikhale ya "rifu ro miyela" leri tolovelekeke eka tihardware leti dyuhaleke. Loko ku nga si tekeriwa enhlokweni software yihi na yihi kumbe fambiselo ro tirha, muchini wu fanele ku rhanga wu kota ku pfula gezi ni ku hundza eka ku kamberiwa ka wona ko sungula ka hardware. Nsinya lowu wa masungulo i ntiyiso eka xitichi xa ntirho xa Sun xa khale tanihi leswi wu nga ntiyiso eka ku lulamisa modyuli leyintshwa eka Mewayz; handle ka xisekelo lexi tiyeke, a ku na nchumu wun’wana lowu nga tirhaka kahle.

Goza ro Sungula: Ku Aka Hi vuntshwa Yuniti ya Mphakelo wa Gezi (PSU)

Nchumu lowu tolovelekeke wa ku tsandzeka eka switirhisiwa swa khale swa elektroniki i mphakelo wa gezi. Ti capacitors, ku nga swiphemu leswitsongo leswi rhetaka gezi, swa onhaka hi ku famba ka nkarhi, hakanyingi swi vupfa electrolyte leyi bolaka. Loko ku pfuriwa PSU, ku kumiwa ka vuvabyi ku tiyisisiwile: ti capacitors to hlaya ti bulged naswona ti vupfile. Ku pfuxeta loku heleleke a ku laveka.

Goza ra Vumbirhi: Ku Lwisana na Vukungundzwana bya NVRAM lebyi nga na Ndhuma yo biha

Hi PSU leyi hanyeke kahle, IPX sweswi yi kombise swikombiso swa vutomi—rivoni ra matimba! Kambe vuhumelerisi bya console byi paluxe xihinga lexi landzelaka: NVRAM (Non-Volatile RAM) leyi onhakeke. Xichipi lexi, i Motorola M48T02, xi hlayisa tipharamitha ta nkoka ta sisiteme ku fana na ID ya host, adirese ya MAC ya Ethernet, na siku ra nkarhi wa siku. Loko betri ya yona ya le ndzeni ka movha yi fa endzhaku ka makume ya malembe, data ya lahleka, naswona sisiteme a yi nge swi koti ku pfula kahle.

Masungulo ya Vumundzuku

Ku vuyisela PSU na NVRAM swi vuyisele IPX leyi ya SPARCstation ku suka emakumu. Sweswi yi na masungulo lama tiyeke lawa yi ma lavaka ku ya emahlweni eka switeji leswi landzelaka: vukamberi bya hardware, ku cinciwa ka drive ya SCSI, naswona eku heteleleni, ku nghenisa sisiteme yo tirha ya Solaris. Endlelo leri ri kandziyisa dyondzo ya nkoka eka sisiteme yihi na yihi, ya khale kumbe leyintshwa. Tanihi leswi Mewayz yi nyikaka xisekelo xa modula, lexi tshembekaka lexi mabindzu ya nga aka na ku pfumelelana na xona, masungulo ya hardware lama vuyeleriweke hi ndlela leyi humelelaka ya pfumelela muchini lowu wa matimu ku tirha nakambe. Eka Xiphemu xa 2, hi ta nghenelela eka sisiteme ya le hansi ya vuhlayiselo na mintlhontlho yo tisa sisiteme yo tirha ya malembe ya 30 eka inthanete.
