I-switch PoE yomhlaba uyinkqubo enkulu yokuxhumana nendawo eyihlanganisa amandla wezixhobo zokuxhumana nezixhobo zokunyela amandla (PoE). Le ndawo encinci ibonisa ukutumathelwa ngokupheleleyo kwezinto kunye nemali ephambili ngemigqa yexeshana, ngelixa iyila kwiindleko zakudityaniswa kwaye kubangelwa ngokupheleleyo kwiteknoloji yomhlaba. Ezi switch zaziwa ngokuba nazo iindleko ezininzi zaseNthenethi ezisebenzisa i-PoE/PoE+ kunye neesipini esizenzekelayo se-SFP okanye SFP+ kwindawo zomhlaba. Ukugcinwa komhlaba kuvumela ukutumathelwa kude kwiikilomitha ezininzi, ngelixa kuthi kudityaniswa kakhulu kwaye kuncinci isathishelo. Izi PoE zaseNthenethi zasekuhlukahlweni zazinake ukusebenza ngokuchasene nokuphathiwa, kuhlanganisa ukuhlelwa kwe-VLAN, iisetting ye-QoS kunye nokugcinwa okupheleleyo. Zinzainkile ukuxhasa izixhobo zexeshana zazo, zinika amandla afumaneka kwi-15.4W ukuya kwi-90W ngasinye, ingxaki yesimahla kunye ne-PoE. Ezi ndawo ziyimali kakhulu kuzo zixhobo ezidinga ukutumathelwa phezulu kwaye nenyelo yamandla kwiindawo zokugqibela njengoko i-cameras zeIP, iindawo zokufikelela kwi-WiFi, kunye nelethu yoVoIP. Okanyayo kwaye okulula kwegcina le fiber, kunye neenkqubo zo-PoE, kuyavumela ukuba zibe yimali kakhulu kuzo zixhobo zentloko, imfanelo yokuqala kunye nezixhobo zokusebenza apho ikhono lokusebenza kunye nekhuba kuyakuphela.

I-switch PoE yase-fiber inika amaphetho aphezulu okwenza kube yisikwahliso esihle kakhulu kwe-inthanethi yesikhathi seshayina. Okokuqala, iyanciphisa izindleko zokufaka ngokuthiwa akudingeki ukusebenzisa amakabili ephatha umoya, ngoba le device zifunda data ne-umoya kuvilakathini elinye. Lokhu kusebenza ngendima eyodwa kanye nokuhlola futhi kunceda ukulungisa imininingwane. Ukuthiwa usebenzisa iteknoloji yase-fiber ikhona ukukhona komkhiqizo ophezulu, ikhanya idata rate kusuka ku-1Gbps kuya ku-10Gbps nangaphezulu, futhi uyacoca ukuthiwa kungenanani isigqoko kanye ne-signal loss phakathi kwezinto ezide. Iinkcukacha zokuphatha umoya ezifakwe phezulu kunazo ukunikeza umoya ngendlela ethintelwe, ngekuwazi ukucoca izinto eziphambene kakhulu kanye nokuhlela ukunikeza umoya ngokwesicelo. Kuhlotsheni lokuphila, iindleke za-fiber zingena ngaphakathi kwezimpawu zokuxhumana nezimpawu zokugcina isiqinisekile kakhulu kuma-tapping. Le switch zinhlobonkalo ezinhle zokulungisa futhi yokukhombisa umoya, ukuze izinto ezithintekayo zipho umoya oqotho. Kwezimali ezifaka kwe-inthanethi, le switch zinikeza ukuthuthukiswa ngokuthiwa kunezindlela eziningi zokuhlanganisa noma zonke iindawo zase-PoE. Izinkcukacha zokuphatha kuzona inkhomba yokusebenza engcono yokuhlela, ukukhombisa futhi ukulungisa imininingwane, ukuze ukuphatha kwe-inthanethi kube lula. Ngaphezulu, ubude bokudluliselana obuphumelelayo, kanye ne-PoE, buvuma ukuthiwa kutholakale izinto ezine-umoya endaweni ongenakho ukuthola umoya. Le switch zinakeke kakhulu ukusebenzisa umoya ngokuthiwa kunezindlela zokuhlela futhi ukukhombisa ukusetshenziswa kwemali, ukucoceka ukuthiwa izimoto zipho impesenti yazo kanye nezinindleko zokusebenza.

Ukuphatha Amandla Okunye Nokuqinisekisa

I-switch PoE yomqondo ikhona kakhulu ekuphileni kwamandla ngokubukeka nezimalo zayo ezinhle. Kungaphinda kwech gate ukuseta amandla nezindlela, okunikeza amadivayisi amathathu ukuthola iseyile sangaphandle kwamandla. Isistimu inikeza ukubukwa ngokwesibonelo kwezimala zokusetshenziswa kwamandla, kulokho abasebenzisa manje angena ukuthatha izinto ngendlela yokusetshenziswa kwamandla kanti akuvumele ukwenqamula. Iinkcukacha ezinhle kufaka phakathi ukuseta amandla ngokuzenzekelayo, okunikeza ukulethwa kwamandla ngokwesikhathi sokude, ubunciphise amandla ekusetshenzisweni ngesikhathi esingaphandle. I-switch wanake fakwe imithwabo yokuphepha eyethula kanye nokuphendula amaphutha amandla, njengokuhlwisa kanti ukushisa okuningi, ukuvinjelwa kwe switch nezinto ezihlotshanisiweyo. Le ndawo yokuphila kwamandla enkulu inikela ukusebenza okuhle ngesikhundla yokugcinwa kwekhaya kanye nokuphephwa kwezinto.

Ukusebenza nokuthobela kwekhaya

Ukuxhumana kwezinhlelo yokusetshenziswa kwamathulani okuqukethwe nezimo zokunikeza amandla (PoE) kube nemiphumela emkhulu kusisekelo nokuthobela. Izixhobo zokuxhumana zisenza lokusebenza okudinga ukusebenzisa amandla ngemirayithi yedatha edlulelwa 10Gbps, ngesikhathi esifanayo sibonisa ukuphephile komsuka phakathi kwezintamo ezingu-70. I-switch esetshenzisa izinkumbulo eziphambene neqoqa lesevisi (QoS), esihlinzekela ukuthi lo msebenzi obaluleke kakhulu uphumelelwe ngaphambi. Inxenye yezinhlelo yokuxhumana engaphandle kwezinhlelo zokugcina amandla ingaqiniselwa ngokushesha kakhulu futhi ayikho lula ukuba kwenzeke ukukhipha amandla angafanele, lokhu kuyindlela enembileyo yokuthumela idatha ebalulekile. Ngokudonsa, i-switch iyisikali sokuvikela imigomo yokuqiniseka, njengokwengeza umthombo wokuxhumana (STP) nokuxhumana okuningi, esihlinzekela ukuthi isisekelo siyasebenza noma xa kukhona amaphutha aphelelwa.

Imigomo yokubekwa nekulawulwa engahlelwa

Lezi sigcwele zinikeza ukusebenzisa ngokuhambelana kakhulu kumaqo kanye nezindlela zokuphatha. Zithuthukela imigqa yamanje wokuxhumana fakwe nendaweni ethile kanye nezindlela ezifanayo. Ukufinyelela ngaphandle kwenqanawa inikeza izinketho eziphezulu zokucushwa, kanye nokwakha i-VLAN, ubuchwepheshe beponti, nokugcina ulayiso lwegidi. Iziphazamiso ezinhloko zokulungisa izinkinga kanye nokuthuthukisa umxhelo wamanje. Le sigcwele zithuthukela izindlela eziningi zokuqinisekisa fakwe nabezindlela zokubuchwephesha, ukuze ikhona lelayo yamanje. Iinkundla zenkululeko yokuphathisa ngaphandle kwenqanawa zivumela abasebenzisi ukucushwa nokugcina isigcwele esikuphi na, apha nezindlela ezomdala zokubamba fakwe nokuziphatha okuvumela ukwenza izilungiselelo. Inkinobeko yokuthuthuka kwesofthwere ngaphandle kwenqanawa iyavumela isigcwele ukuthi ithinte amagreqo athuthukayo yamanje nabezindlela zokubuchwephesha.
