Ezweni elihlala lishintsha lobuchwepheshe benethiwekhi, ukukhetha iswishi kubalulekile ekusebenzeni kahle kwenethiwekhi kanye nokusebenza kwayo. Phakathi kwezinhlobo eziningi zamaswishi, amaswishi e-Power over Ethernet (PoE) athole ukunakwa okukhulu ngenxa yezici zawo ezihlukile. Ukuqonda umehluko phakathi kwamaswishi e-PoE kanye namaswishi ajwayelekile kubalulekile kumabhizinisi nakubantu ngabanye abafuna ukuthuthukisa ingqalasizinda yabo yenethiwekhi.
A Iswishi ye-PoE iyidivayisi yenethiwekhi engagcini nje ngokusekela ukudluliswa kwedatha kodwa futhi enikeza amandla kumadivayisi axhunyiwe ngekhebula le-Ethernet elifanayo. Lobu buchwepheshe buvumela amadivayisi afana namakhamera e-IP, amafoni e-VoIP, kanye nezindawo zokufinyelela ezingenantambo ukuthola idatha kanye namandla ngesikhathi esisodwa, okuqeda isidingo sokunikezwa kwamandla okuhlukile. Izinkinobho ze-PoE ziyatholakala ngezindinganiso eziningana, kufaka phakathi i-IEEE 802.3af (PoE), i-IEEE 802.3at (PoE+), kanye ne-IEEE 802.3bt (PoE++, ngayinye inikeza amazinga amandla ahlukene ukuze kuhlangatshezwane namadivayisi ahlukahlukene.
Ngakolunye uhlangothi, amaswishi ajwayelekile angamadivayisi enethiwekhi avamile asetshenziselwa kakhulu ukudlulisa idatha. Awanikezi amandla kumadivayisi axhunyiwe, okusho ukuthi noma iyiphi idivayisi edinga amandla kumele ixhunywe endaweni ehlukile yokukhipha amandla. Amaswishi ajwayelekile avame ukusetshenziswa ezindaweni lapho amadivayisi esevele enikwe amandla noma lapho amandla engekho inkinga.
Amandla:Umehluko obaluleke kakhulu phakathi kweswishi ye-PoE kanye neswishi evamile ikhono layo lokuletha amandla. Iswishi ye-PoE inganika amandla amadivayisi ngekhebula le-Ethernet, kuyilapho iswishi evamile ingakwazi. Lesi sici senza kube lula ukufakwa futhi sinciphise ukuminyana kwezintambo nama-adapter kagesi.
Ukuguquguquka kokufakwa:Amaswishi e-PoE anikeza ukuguquguquka okukhulu ekubekweni kwedivayisi. Ngenxa yokuthi awadingi indawo yokukhipha ugesi eseduze, amadivayisi angafakwa ezindaweni lapho ugesi ungatholakali kalula, njengamakhamera e-IP afakwe ophahleni noma ezindaweni ezikude zezindawo zokufinyelela ezingenantambo. Nokho, amaswishi avamile adinga ukuthi amadivayisi abekwe lapho ugesi utholakala khona.
Ukusebenza kahle kwezindleko:Nakuba izindleko zokuqala zamaswishi e-PoE zingase zibe phezulu kuneziswishi ezivamile, zingonga imali ngokuhamba kwesikhathi. Ngokunciphisa isidingo sezintambo ezengeziwe kanye nezindawo zokuxhuma, amabhizinisi angonga ezindleleni zokufaka nokulungisa. Ngaphezu kwalokho, ikhono lokunika amandla amadivayisi amaningi ngeswishi eyodwa kunciphisa ukusetshenziswa kwamandla.
Ukuphathwa kwenethiwekhi:Ama-switch amaningi e-PoE afakwe izici zokuphatha ezithuthukisiwe ezivumela ukulawula okungcono nokuqapha amadivayisi axhunyiwe. Lokhu kufaka phakathi ukubeka phambili amandla, ukuqapha ukusetshenziswa kwamandla, ngisho nokuqalisa kabusha amadivayisi kude. Lezi zici zokuphatha ezithuthukisiwe zivame ukuntuleka kuma-switch ajwayelekile.
Ukukwazi ukukhula:Ama-switch e-PoE ngokuvamile anwebeka kakhulu kune-switch ejwayelekile. Njengoba ibhizinisi lakho likhula futhi lidinga amadivayisi amaningi, ama-switch e-PoE angamukela kalula amadivayisi amasha ngaphandle kokudinga umsebenzi omkhulu kagesi. Ama-switch ajwayelekile, ngakolunye uhlangothi, angadinga ingqalasizinda eyengeziwe ukusekela amadivayisi amasha asebenza ngamandla.
Ekugcineni, ukukhetha phakathi kwe- Iswishi ye-PoE futhi ukushintsha okujwayelekile kuncike ezidingweni ezithile zenethiwekhi yakho. Ezindaweni ezidinga amadivayisi asebenza ngamandla, ukushintsha kwe-PoE kunikeza izinzuzo ezibalulekile ekulethweni kwamandla, ukuguquguquka kokufakwa, ukusebenza kahle kwezindleko, ukuphathwa kwenethiwekhi, kanye nokukhula. Ukuqonda lokhu mehluko kungasiza amabhizinisi nabantu ngabanye ukuba benze izinqumo ezinolwazi lapho beklama futhi bethuthukisa ingqalasizinda yabo yenethiwekhi. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, indima yokushintsha kwe-PoE kumanethiwekhi anamuhla cishe izogqama kakhulu, ibenze babe yimpahla ebalulekile kunoma iyiphi inhlangano.
