A I-transformer ye-LAN, eyaziwa nangokuthi i-Local Area Network (LAN) transformer, iyidivayisi yokuxhumeka kwenethiwekhi esetshenziselwa ukuxhuma amadivayisi.Xhuma imbobo yeswishi yenethiwekhi kunethiwekhi yendawo (LAN) ngokusebenzisa iswishi, bese uxhuma i-inthanethi eminingi noma amanye amakhompyutha namaseva ku-LAN kudivayisi efanayo ye-LAN.Inezici ezilandelayo:
1. Asikho isidingo sanoma yikuphi ukuzihlukanisa ngokomzimba noma okunengqondo phakathi kweswishi yenethiwekhi nezinye izindawo zokufinyelela, ngakho ukusebenza kwayo kukagesi nokusebenza kwesistimu kungcono kunamakhompyutha avamile, futhi ingakwazi ukushintshanisa kalula ulwazi lwenethiwekhi ngaphandle komthungo namanye amathuluzi;
2. Njengoba kunechweba elilodwa noma ngaphezulu ku-LAN yokuxhuma amakhompiyutha nezinye izikhumulo, zingase futhi zicushwe kahle ukuze zihlangabezane nezidingo zokuxhuma phakathi kwamadivayisi ahlukene;
3. Njengoba amachweba we-switch yenethiwekhi kanye nesiphetho singacushwa ngokuhlukana, umsebenzi wokushintsha inethiwekhi nawo ungenziwa kalula.
Umgomo wokusebenza we-LAN transformer:
II-transformer ye-LANisetshenziswa kakhulu ukuvikela ukushintshwa kwenethiwekhi.Uma isisetshenziswa senethiwekhi sihluleka, iswishi ayikwazi ukusebenza ngokujwayelekile.Umsebenzi wokuvikela okuzenzakalelayo we-transformer ye-LAN ungaxazulula inkinga ngokushesha nangempumelelo.Umsebenzi oyinhloko:
1. Setha ukuhlukaniswa kwembobo noma ukuvikela imbobo kuswishi ukuze wenze iswishi isebenze ngendlela evamile.
2. Uma umshini wehluleka, isifunda sokuvikela esizenzakalelayo se-transformer yenethiwekhi yendawo sizobona ukwehluleka futhi siqalise kabusha ukusebenza kwenethiwekhi.
3. Setha imithetho ye-firewall ehlukene ngokuya ngamapharamitha enethiwekhi ukuze uhlukanise noma uvikele izimbobo.
Inhloso yeI-transformer ye-LAN:
Isetshenziselwa ikakhulukazi ukunikezwa kwamandla kwemishini yokudlulisa inethiwekhi.Inhloso yesiguquli se-LAN, ngaphezu kokuhlinzeka ngamandla kwezinye izisetshenziswa zokudlulisa inethiwekhi njengamarutha, amaswishi, njll., ingaphinda isetshenziselwe ukunikeza amandla kwezinye izisetshenziswa zokuxhumana (njenge-wireless AP, njll.) kwezinye izisetshenziswa idinga ukunikezwa kwamandla.I-LAN transformer iyithuluzi eliguqula amandla kagesi kwamanye amadivaysi adinga ukunikezwa kwamandla (njengamarutha, amaswishi, njll.).Isiguquli senethiwekhi yendawo ngokuvamile siguqula amandla e-AC sibe amandla e-DC, futhi siguqule amandla angu-220V AC sibe amandla aphumayo e-DC acishe abe ngu-48V, ukuze okokusebenza okuhlinzekiwe kusebenze ngokujwayelekile.Kumadivayisi ahlukahlukene okuxhumana asetshenziswa ku-LAN, njengama-AP angenawaya, amarutha, amaswishi, njll., nawo adinga ugesi ongu-24V noma 48V ukuze anikeze amandla awo.Kwezinye izisetshenziswa zokuxhumana ezidinga ukunikezwa kwamandla ka-24V kanye nogesi we-12v noma i-9v, i-transformer ye-LAN ingaxazulula le nkinga.Uma usebenzisa ama-switch, ama-routers, njll. kumatheminali anjalo okuxhumana, i-voltage engu-10 ~ 20V ingashintshwa ibe yi-voltage engu-48~60V, ukuze isiphetho esinikeziwe sikwazi ukusebenza ngokujwayelekile;kulula nakakhulu ukusetshenziswa kwama-APs angenawaya, udinga nje ukuvula amandla kagesi Vele uyiguqule ibe yi-12V-2A.
