A Isiguquli se-LAN, eyaziwa ngokuba yiNdawo yeNgingqi yeNgingqi (LAN) isiguquli, sisixhobo soqhagamshelwano lwenethiwekhi esisetyenziselwa ukuqhagamshela izixhobo.Qhagamshela izibuko lokutshintsha kwenethiwekhi kwinethiwekhi yendawo yendawo (LAN) ngokutshintsha, kwaye uqhagamshele i-Intanethi ezininzi okanye ezinye iikhompyuter kunye neeseva kwi-LAN kwisixhobo esifanayo seLAN.Inezi mpawu zilandelayo:
1. Akukho mfuneko yokwahlula ngokwasemzimbeni okanye okusengqiqweni phakathi kokutshintsha kwenethiwekhi kunye nezinye iitheminali zokufikelela, ngoko ukusebenza kwayo kombane kunye nokusebenza kwenkqubo ingcono kuneekhompyuter eziqhelekileyo, kwaye inokutshintshisa ngokulula ulwazi lwenethiwekhi ngokungenamthungo kunye nezinye izixhobo;
2. Ekubeni kukho izibuko enye okanye ngaphezulu kwi-LAN yokudibanisa iikhomputha kunye nezinye iitheminali, ziyakwazi ukuqwalasela ngokufanelekileyo ukuhlangabezana neemfuno zoqhagamshelwano phakathi kwezixhobo ezahlukeneyo;
3. Ekubeni amachweba okutshintsha kwenethiwekhi kunye ne-terminal inokuqwalaselwa ngokwahlukileyo, umsebenzi wokutshintsha inethiwekhi unokuphunyezwa ngokulula.
Umgaqo osebenzayo we-LAN transformer:
IIsiguquli se-LANisetyenziselwa ikakhulu ukhuseleko lokutshintsha kwenethiwekhi.Xa isixhobo senethiwekhi singaphumeleli, iswitshi ayikwazi ukusebenza ngokuqhelekileyo.Umsebenzi wokukhusela ngokuzenzekelayo we-LAN transformer unokusombulula ingxaki ngokukhawuleza nangempumelelo.Owona msebenzi ungundoqo:
1. Cwangcisa ukwahlukaniswa kwezibuko okanye ukhuseleko lwezibuko kwiswitshi ukwenza iswitshi isebenze ngokuqhelekileyo.
2. Xa umtshini ungaphumeleli, isiphaluka sokukhusela ngokuzenzekelayo kwi-transformer yendawo yendawo iya kubona ukungaphumeleli kwaye iphinde iqalise ukusebenza kwenethiwekhi.
3. Misela imigaqo yomlilo eyahlukeneyo ngokweeparamitha zothungelwano ukwahlula okanye ukukhusela amazibuko.
Injongo yeIsiguquli se-LAN:
Isetyenziselwa ubukhulu becala unikezelo lwamandla lwezixhobo zothumelo lwenethiwekhi.Injongo yesiguquli se-LAN, ukongeza ekuboneleleni amandla kwezinye izixhobo zothumelo lwenethiwekhi ezinjengee-router, iiswitshi, njalo njalo, zingasetyenziselwa ukunika amandla kwezinye izixhobo zonxibelelwano (ezifana ne-wireless AP, njl. njl.) kwezinye izixhobo ezithi ifuna unikezelo lwamandla.I-LAN transformer sisixhobo esiguqula i-voltage yezinye izixhobo ezifuna ukunikezelwa kwamandla (njengama-routers, switch, njl.).Isiguquli sothungelwano lwengingqi ngokubanzi siguqula amandla e-AC kumandla e-DC, kwaye siguqula amandla e-220V AC abe yimveliso yamandla e-DC emalunga ne-48V, ukuze izixhobo ezibonelelweyo zisebenze ngokwesiqhelo.Kwizixhobo ezahlukeneyo zonxibelelwano ezisetyenziswa kwi-LAN, ezinjengee-AP ezingenazingcingo, iirotha, iiswitshi, njl., nazo zifuna i-24V okanye i-48V unikezelo lwamandla ombane wabo.Kwezinye izixhobo zonxibelelwano ezifuna umbane we-24V kunye ne-12v okanye i-9v unikezelo lwamandla, i-transformer ye-LAN inokusombulula le ngxaki.Xa usebenzisa iiswitshi, ii-routers, njl njl kwii-terminals zonxibelelwano ezinjalo, i-voltage ye-10 ~ 20V inokuguqulwa ibe yi-48 ~ 60V ye-voltage, ukwenzela ukuba isiphelo esinikezelweyo sisebenze ngokuqhelekileyo;ilula ngakumbi kusetyenziso lwee-APs ezingenazingcingo, kufuneka nje ujike unikezelo lwamandla Yitshintshe nje ibe yi-12V-2A.
