Pamene inu (kapena ntchito yanu) mukusowa chingwe cha crossover
Chingwe cha crossover, nthawi zina chotchedwa chingwe chodutsa , chimagwirizanitsa zipangizo ziwiri za Ethernet zamakina. Zidalengedwera kuthandizira maulendo ochezera osamalidwa panthawi yomwe chida chosakanikirana ngati network router sichiripo .
Zipangizo za Crossover zikuwoneka mofanana ndi zingwe zamtundu wodabwitsa, zoongoka (kapena patch ) Ethernet mpaka mawonekedwe awo amkati akuwonekera.
Crossover vs Straight Through Cable
Galama yabwino, yotchinga imagwiritsidwa ntchito kugwirizanitsa mitundu yosiyanasiyana ya zipangizo palimodzi, monga makompyuta kupita kusinthana. Chingwe cha crossover chimakhala chosiyana - chimagwirizanitsa zipangizo ziwiri zofanana.
Mapulogalamu a chingwechi amatha kuwombera mwanjira iliyonse pokhapokha mapeto onsewo ali ofanana. Poyerekeza ndi makwerero a Ethernet molumikizika, mawindo a mkati mwa chingwe cha crossover amatsitsa zizindikiro zofalitsira ndi kulandira.
Mitundu yododometsedwa ya mitundu imatha kuwonedwa kudzera pa ojambulira RJ-45 pamapeto onse a chingwe:
- Zingwe zazing'ono zili ndi ndondomeko yofanana ya mawaya amitundu pamapeto onse
- Zingwe za Crossover zili ndi mawaya oyambirira ndi atatu (kuwerengera kuyambira kumanzere kupita kumanja) kudutsa, ndipo waya wamba ndi wachisanu ndi chimodzi anawoloka
Chingwe chabwino cha Ethernet crossover chidzasankhidwa mwachindunji kuti chichidziwitse icho kuchokera molunjika kupyolera mwa iwo. Ambiri ali ofiira komanso amawoneka "crossover" pamapangidwe ake ndi waya.
Kodi Mukusowa Chingwe cha Crossover?
Zingwe za Crossover zimagwiritsidwa ntchito kwambiri ndi akatswiri a Information Technology (IT) m'ma 1990s ndi 2000s chifukwa machitidwe otchuka a Ethernet panthawiyo sankathandiza kugwirizana kwachindunji pakati pa makamu.
Maofesi onse oyambirira ndi Fast Ethernet anapangidwa kuti agwiritse ntchito mawaya enieni onse opatsirana ndi kulandira. Miyezo imeneyi inkafuna mapeto awiri kuti alankhulane kupyolera mu chipangizo chapakati kuti athetse mikangano poyesera kugwiritsa ntchito mawaya omwewo kuti azifalitsa ndi kulandira.
Chizindikiro cha Ethernet chotchedwa MDI-X chimapereka chithandizo chofunikira chodziwitsira chodziletsa kuti zisawononge izi. Amalola mawonekedwe a Ethernet kuti azindikire kuti ndi chiyani chomwe chikugwiritsidwa ntchito pamapeto ena a akatswiri a chingwe ndikukambirana za kugwiritsa ntchito mawaya opatsirana ndi kulandira. Onani kuti mapeto amodzi okha afunika kugwirizanitsa kudziwonetsera kwa gawoli kuti agwire ntchito.
Maulendo ambiri apanyumba apanyumba (ngakhale zitsanzo zakale) amaphatikizapo thandizo la MDI-X pa ma Ethernet. Gigabit Ethernet inagwiritsanso ntchito MDI-X ngati choyimira.
Zingwe za Crossover zimangowonjezeka pogwirizanitsa makina awiri a makasitomala a Ethernet komwe sanagwiritsidwe ntchito pa Gigabit Ethernet. Zida zamakono za Ethernet tsopano zimangozindikira kugwiritsa ntchito zingwe za crossover ndikugwira nawo ntchito mosagwedera.
Mmene Mungagwiritsire Ntchito Zingwe za Ethernet Crossover
Zingwe za Crossover ziyenera kugwiritsidwa ntchito pazowonongeka mwachindunji. Chifukwa chafotokozedwera pamwambapa, kuyesa kugwirizanitsa kompyuta ku router wakale kapena kusinthana kusinthana ndi chingwe cha crossover mmalo mwa chingwe chozoloŵera, chingalepheretse kulumikizana kuti zisagwire ntchito.
Zipangizozi zingathe kugulitsidwa makamaka kudzera m'magetsi osiyanasiyana. Othandizira ena ndi akatswiri ena a IT angapange kupanga zingwe zawo za crossover mmalo mwake.
Chowongolera molunjika chingakhale mwamsanga mwasandulika chingwe cha crossover mwa kuchotsa chojambulira ndi kubwezeretsanso mawaya ndi waya oyenera kulandira ndi kulandira.
