Netiweki switch ndiyo musana wemazuva ano ekutaurirana network, kuve nechokwadi chekuyerera kwe data pakati pemidziyo mumabhizinesi nenzvimbo dzemaindasitiri. Kugadzirwa kwezvikamu zvakakosha izvi kunosanganisira nzira yakaoma uye ine hunyanzvi inosanganisa tekinoroji yekucheka, chaiyo engineering uye yakasimba kutonga kwemhando kuendesa yakavimbika, yepamusoro-inoshanda michina. Heino kuseri-kwe-zviratidziro tarisa maitiro ekugadzira eiyo network switch.
1. Dhizaini nekusimudzira
Rwendo rwekugadzira retiweki switch rinotanga nedhizaini nekusimudzira chikamu. Mainjiniya nevagadziri vanoshanda pamwechete kugadzira akadzama zvirevo uye mapurani zvinoenderana nezvinodiwa zvemusika, kufambira mberi kwetekinoroji uye zvinodiwa nevatengi. Danho iri rinosanganisira:
Circuit dhizaini: Mainjiniya vanogadzira maseketi, kusanganisira akadhindwa redunhu bhodhi (PCB) inoshanda semusana wekuchinja.
Sarudzo yechikamu: Sarudza zvemhando yepamusoro, senge processors, memory machipi, uye magetsi emagetsi, anosangana nekuita uye kusimba zviyero zvinodiwa kunetiweki switch.
Prototyping: Prototypes inogadzirwa kuti iedze mashandiro, kuita, uye kuvimbika kwedhizaini. Iyo prototype yakaedzwa zvakaomarara kuona chero kukanganisa dhizaini kana nzvimbo dzekuvandudza.
2. PCB kugadzirwa
Kana dhizaini yapera, maitiro ekugadzira anoenda muPCB yekugadzira nhanho. PCBs zvinhu zvakakosha zvinogadzira magetsi maseketi uye zvinopa chimiro chemuviri chetiweki switch. Iyo nzira yekugadzira inosanganisira:
Layering: Kuisa akawanda akaturikidzana emhangura inoitisa kune isiri-conductive substrate inogadzira nzira dzemagetsi dzinobatanidza zvikamu zvakasiyana.
Etching: Kubvisa mhangura isingakoshi kubva pabhodhi, ichisiya iyo chaiyo yedunhu pateni inodiwa pakuchinja kushanda.
Kuchera nePlating: Dhonza maburi muPCB kufambisa kuiswa kwezvikamu. Maburi aya anobva avharwa neconductive material kuti ave nechokwadi chekubatanidza magetsi.
Solder Mask Application: Isa inodzivirira solder mask kuPCB kudzivirira mapfupi maseketi uye kudzivirira wedunhu kubva mukukuvadzwa kwezvakatipoteredza.
Silk Screen Printing: Mazita uye zviziviso zvakadhindwa paPCB kutungamira kusangana uye kugadzirisa matambudziko.
3. Zvikamu musangano
Kana PCB yagadzirira, danho rinotevera ndere kuunganidza zvikamu pabhodhi. Danho iri rinosanganisira:
Surface Mount Technology (SMT): Kushandisa otomatiki muchina kuisa zvikamu paPCB pamusoro nekunyanya kurongeka. SMT ndiyo nzira inosarudzika yekubatanidza zvidiki, zvakaomarara senge resistors, capacitors, uye akabatanidzwa maseketi.
Kuburikidza neHole Tekinoroji (THT): Kune zvikamu zvakakura zvinoda rubatsiro rwekuwedzera michina, kuburikidza ne-gomba zvikamu zvinoiswa mumakomba akafanocherwa uye anotengeswa kuPCB.
Reflow soldering: Iyo yakaunganidzwa PCB inopfuura nemuhovheni inoyerera apo solder paste inonyunguduka nekuomesa, ichigadzira yakachengeteka yemagetsi kubatana pakati pezvikamu nePCB.
4. Firmware programming
Kana gungano remuviri rapera, network switch's firmware inorongwa. Firmware ndiyo software inodzora kushanda uye kushanda kwehardware. Danho iri rinosanganisira:
Kuiswa kweFirmware: Firmware inoiswa mundangariro yekuchinja, ichiibvumira kuita mabasa akakosha senge packet switching, routing, uye network manejimendi.
Kuedza uye Calibration: Iyo switch inoedzwa kuti ive nechokwadi chekuti firmware yakaiswa nemazvo uye mabasa ese ari kushanda sezvaitarisirwa. Iyi nhanho inogona kusanganisira kuyedza kushushikana kuti ione chinja mashandiro pasi peakasiyana mitoro yetiweki.
5. Kudzora Kwehutano uye Kuedzwa
Kudzora kwemhando chikamu chakakosha chemaitiro ekugadzira, kuve nechokwadi chega chega chetiweki chinosangana nemhando yepamusoro yekuita, kuvimbika uye chengetedzo. Danho iri rinosanganisira:
Kushanda Kuyedzwa: Imwe neimwe switch inoedzwa kuti ive nechokwadi chekuti iri kushanda nemazvo uye kuti ese madoko uye maficha ari kushanda sezvaitarisirwa.
Kuyedzwa kwezvakatipoteredza: Shanduko dzinoedzwa tembiricha, hunyoro, uye vibration kuti ive nechokwadi chekuti dzinogona kumira kwakasiyana siyana dzekushanda.
EMI / EMC Kuedzwa: Electromagnetic interference (EMI) uye electromagnetic kuenderana (EMC) kuyedzwa kunoitwa kuti ive nechokwadi chekuti switch haibudise mwaranzi inokuvadza uye inogona kushanda nezvimwe zvigadzirwa zvemagetsi pasina kukanganisa.
Burn-in kuyedza: Iyo switch inobatidzwa uye inomhanya kwenguva yakawedzerwa yenguva kuona chero hurema kana kutadza kunogona kuitika nekufamba kwenguva.
6. Kusangana kwekupedzisira uye kurongedza
Mushure mekupasa ese emhando yekudzora bvunzo, network switch inopinda mugungano rekupedzisira uye yekurongedza. Izvi zvinosanganisira:
Enclosure Assembly: Iyo PCB uye zvikamu zvakaiswa mukati memuvharo wakasimba wakagadzirirwa kuchengetedza switch kubva mukukuvara kwemuviri uye zvakatipoteredza zvinhu.
Labeling: Imwe neimwe switch yakanyorwa neruzivo rwechigadzirwa, serial nhamba, uye kudzora kutevedza kumaka.
Packaging: Iyo switch yakanyatsorongedzwa kuti ipe dziviriro panguva yekutumira nekuchengetedza. Iyo package inogona zvakare kusanganisira bhuku remushandisi, magetsi emagetsi, uye zvimwe zvishongedzo.
7. Kutumira uye Kugovera
Kana yaiswa mukati, network switch yakagadzirira kutumirwa uye kugovera. Vanotumirwa kunzvimbo dzekuchengetera zvinhu, vanogovera kana zvakananga kune vatengi pasirese. Chikwata chekugadzirisa zvinhu chinova nechokwadi chekuti ma switch anounzwa zvakachengeteka, nenguva, uye akagadzirira kuendeswa munzvimbo dzakasiyana siyana dzetiweki.
mukupedzisa
Kugadzirwa kwetiweki switch idanho rakaomarara rinosanganisa tekinoroji yepamberi, hunyanzvi hwehunyanzvi uye yakasimba kuvimbiswa kwemhando. Yese nhanho kubva pakugadzira uye PCB kugadzira kuungana, kuyedzwa uye kurongedza kwakakosha kuendesa zvigadzirwa zvinosangana nezvinodiwa zvakanyanya zvemazuva ano network network. Semusana wematanho emazuva ano ekutaurirana, ma switch aya anoita basa rakakosha mukuona kuti data yakavimbika uye inoshanda inoyerera mumaindasitiri nemashandisirwo.
