Amandla phezu kwe-Ethernet (POE)ubuchwepheshe buye benza izinguquko endleleni esinika amandla ngayo amadivayisi ethu, sinikeza ukunethezeka, ukusebenza kahle kanye nokonga kwezindleko. Ngokuhlanganisa amandla nokudluliswa kwedatha kukhebula ye-Ethernet, i-POE iqeda isidingo sentambo yamandla ehlukile, iyenze ilungele izinhlelo zokusebenza ezihlukahlukene ezifana namakhamera we-IP, izindawo zokufinyelela ezingenantambo, namafoni e-VoIP. Kodwa-ke, ngaphambi kokutshala imali kunoma yisiphi isisombululo senethiwekhi, kubalulekile ukuqonda umehluko phakathi kokushintsha kwe-POE okujwayelekile nokungajwayelekile.

Ukushintsha okujwayelekile kwe-POE kulandela amazinga e-Institute of Electrical and Electronics Engineers (IEEE) 802.3af noma 802.3at. Lawa mazinga aqashelwa umkhakha acacisa umthamo omkhulu wamandla ongalethwa iswishi kumadivayisi athobela i-POE. Ukunikezwa kwamandla okuvame kakhulu ekushintsheni kwe-POE okujwayelekile kungu-48V.

Ngakolunye uhlangothi, ukushintsha okungajwayelekile kwe-POE kungase kungahambisani nalawa mazinga e-IEEE. Bavame ukusebenzisa izindlela zobunikazi eziphambuka ezinkambisweni ezimisiwe. Nakuba lezi zinguquko zingase zibonakale ziyinketho esebenzayo ngenxa yezindleko zazo ezingase zibe phansi, azinakho ukusebenzisana nokuthembeka kokushintsha kwe-POE okujwayelekile. Kubalulekile ukuqonda umehluko phakathi kokubili kanye nezingozi ezingaba khona ezihlobene nokungajwayelekileUkushintsha kwe-POE.

Umehluko owodwa obalulekile phakathi kokushintsha kwe-POE okujwayelekile nokungajwayelekile amandla kagesi abawanikezayo kumadivayisi axhunyiwe. OkujwayelekileUkushintsha kwe-POEsebenzisa amandla angu-48V. Lezi zinketho zamukelwa kabanzi futhi zisekelwa amadivayisi amaningi anikwe amandla i-POE emakethe. Banikeza amandla athembekile, azinzile, aqinisekisa ukusebenza okungenamthungo nokusebenza kahle.

Ngokuphambene, amaswishi e-POE angajwayelekile asebenzisa izinketho zamandla kagesi ngaphandle kwama-48V. Ngenkathi ezinye zalezi zinguquko zinikeza amandla aphezulu okulethwa kwamandla, azihambisani namadivayisi ajwayelekile e-POE. Lokhu kungahambisani kungabangela izinkinga ezihlukahlukene, okuhlanganisa ukushoda kwamandla, ukunciphisa ukusebenza kwedivayisi, ngisho nokulimala okungaba khona kumadivayisi axhunyiwe.

Ukuze uhlukanise phakathi kokushintsha kwe-POE okujwayelekile nokungajwayelekile, qala ngokubheka imininingwane yokunikezwa kwamandla okunikezwa umkhiqizi weswishi. Amaswishi ahambisanayo azobonisa ngokucacile ukuthi ayahambisana yini ne-IEEE 802.3af noma 802.3at ejwayelekile, kanye nezinketho zikagesi ezizisekelayo. Lezi zinguquko zizocacisa umthamo omkhulu wamandla wembobo ngayinye, kuqinisekiswe ukuthi ungakwazi ukunika amandla ngokuphephile amadivayisi e-POE.

Ngakolunye uhlangothi, ukushintsha okungajwayelekile kwe-POE kungase kungabambeleli kulawa mazinga achazwe kahle. Bangase banikeze ukuphuma kwamandla aphezulu noma basebenzise izinketho zamandla kagesi ezingajwayelekile, njenge-12V noma i-56V. Qaphela lapho ucabangela lolu hlobo lweswishi njengoba lungase lunganikezi amaleveli wamandla adingwa idivayisi yakho noma lungabangela idivayisi ukuthi ihluleke ngaphambi kwesikhathi.

Enye indlela yokuhlukanisa phakathi kokushintsha kwe-POE okujwayelekile nokungajwayelekile ukuthembela kubakhiqizi bemishini yenethiwekhi abahlonishwayo. Abakhiqizi abasunguliwe bakhiqiza amaswishi e-POE athembekile futhi ajwayelekile ahambisana nokucaciswa komkhakha. Bahlolwa kanzima ukuze bahlangabezane nezindinganiso zekhwalithi futhi balethe ukusebenza okuphakeme.

Uma udinga ukushintsha kwe-POE, ungasithinta nganoma yisiphi isikhathi. Inkampani yethu,I-JHA Tech, ibilokhu igxile ku-R & D, ukukhiqizwa nokudayiswa kokushintshwa okuhlukahlukene kusukela ngo-2007. Ayinayo nje inzuzo enkulu kakhulu ngentengo, kodwa futhi iqinisekisiwe kakhulu ngekhwalithi ngoba sithole izitifiketi zobuchwepheshe nezigunyazayo;
