Umehluko phakathi kokushintsha kwe-PoE namaswishi ajwayelekile

Ezweni elihlala livela lobuchwepheshe benethiwekhi, ukukhetha ukushintsha kubalulekile ekusebenzeni kahle kwenethiwekhi nokusebenza. Phakathi kwezinhlobo eziningi zokushintshwa, amaswishi Amandla phezu kwe-Ethernet (PoE) athole ukunakwa okubalulekile ngenxa yezici zawo ezihlukile. Ukuqonda umehluko phakathi kokushintsha kwe-PoE nokushintsha okujwayelekile kubalulekile emabhizinisini nakubantu abafuna ukuthuthukisa ingqalasizinda yabo yenethiwekhi.

A Shintshanisa amasheya PoE iyidivayisi yenethiwekhi engasekeli ukudluliswa kwedatha kuphela kodwa futhi inikeza amandla kumadivayisi axhunyiwe ngekhebula ye-Ethernet efanayo. Lobu buchwepheshe buvumela amadivayisi afana namakhamera we-IP, amafoni e-VoIP, namaphoyinti okufinyelela angenantambo ukuthi athole kokubili idatha namandla ngesikhathi esisodwa, okuqeda isidingo sokuphakelwa kwamandla okuhlukile. Amaswishi e-PoE atholakala ngamazinga amaningana, okuhlanganisa i-IEEE 802.3af (PoE), IEEE 802.3at (PoE+), ne-IEEE 802.3bt (PoE++), ngayinye inikezela ngamaleveli ahlukene wamandla ukuze kufakwe amadivayisi ahlukahlukene.

Ukushintsha okujwayelekile, ngakolunye uhlangothi, kungamadivayisi enethiwekhi endabuko asetshenziselwa ngokuyinhloko ukudlulisa idatha. Azinikezi amandla kumadivayisi axhunyiwe, okusho ukuthi noma iyiphi idivayisi edinga amandla kufanele ixhunywe endaweni ehlukile yamandla. Ukushintsha okujwayelekile kuvamise ukusetshenziswa ezindaweni lapho amadivayisi asevele enikwe amandla noma lapho amandla angeyona into ekhathazayo.

Amandla:Umehluko obaluleke kakhulu phakathi kweswishi ye-PoE kanye nokushintsha okujwayelekile amandla ayo okulethwa kwamandla. Iswishi ye-PoE inganika amandla amadivayisi ngekhebula ye-Ethernet, kuyilapho iswishi evamile ingakwazi. Lesi sici senza ukufakwa kube lula futhi sinciphisa ukuhlangana kwezintambo nama-adaptha amandla.

Ukuvumelana nezimo zokufaka:Ukushintsha kwe-PoE kunikeza ukuguquguquka okukhulu ekubekweni kwedivayisi. Ngenxa yokuthi awadingi indawo kagesi eseduze, amadivayisi angafakwa ezindaweni lapho amandla engatholakali kalula, njengamakhamera we-IP abekwe kusilingi noma izindawo ezikude zezindawo zokufinyelela okungenantambo. Ukushintsha okujwayelekile, nokho, kudinga ukuthi kubekwe amadivaysi lapho amandla etholakala khona.

Ukusebenza kahle kwezindleko:Nakuba izindleko zokuqala zokushintshwa kwe-PoE zingase zibe phezulu kunokushintsha okujwayelekile, zingonga imali ngokuhamba kwesikhathi. Ngokunciphisa isidingo sezintambo ezengeziwe kanye nezitolo, amabhizinisi angonga ezindlekweni zokufaka nokulungisa. Ukwengeza, amandla okunika amandla amadivaysi amaningi ngokusebenzisa iswishi eyodwa kunciphisa ukusetshenziswa kwamandla.

Ukuphathwa kwenethiwekhi:Amaswishi amaningi e-PoE afika efakwe izici zokuphatha ezithuthukile ezivumela ukulawula nokuqapha okungcono kwamadivayisi axhunyiwe. Lokhu kubandakanya ukubeka phambili amandla, ukuqapha ukusetshenziswa kwamandla, kanye nokuqalisa kabusha amadivayisi ukude. Lezi zici zokuphatha ezithuthukisiwe zivame ukuntula ekushintsheni okujwayelekile.

I-Scalability:Amaswishi e-PoE ngokuvamile ayakala kakhulu kunokushintsha okujwayelekile. Njengoba ibhizinisi lakho likhula futhi lidinga amadivayisi amaningi, amaswishi e-PoE angamukela kalula amadivayisi amasha ngaphandle kokudinga umsebenzi omkhulu kagesi. Ngakolunye uhlangothi, ukushintsha okujwayelekile kungase kudinge ingqalasizinda eyengeziwe ukuze kusekelwe amadivayisi amasha anamandla.

Ekugcineni, ukukhetha phakathi kwe-a Shintshanisa amasheya PoE futhi ukushintsha okujwayelekile kuncike ezidingweni ezithile zenethiwekhi yakho. Ezindaweni ezidinga amadivayisi anamandla, ukushintsha kwe-PoE kunikeza izinzuzo ezibalulekile ekulethweni kwamandla, ukuguquguquka kokufakwa, ukuphumelela kwezindleko, ukuphathwa kwenethiwekhi, kanye nokuqina. Ukuqonda lo mehluko kungasiza amabhizinisi nabantu ngabanye benze izinqumo ezinolwazi lapho beklama futhi bethuthukisa ingqalasizinda yabo yenethiwekhi. Njengoba ubuchwepheshe buqhubeka buthuthuka, indima yokushintshwa kwe-PoE kumanethiwekhi esimanje kungenzeka igqame nakakhulu, iwenze abe yimpahla ebalulekile yanoma iyiphi inhlangano.
