Iyini i-POE Power Over Ethernet? - Network Technology Guide
Amandla phezu kwe-Ethernet (i-PoE) ubuchwepheshe obushintsha umdlalo wamanethiwekhi esimanje. Ivumela idatha namandla ukuthi ageleze ngekhebuli eyodwa ye-Ethernet. Lokhu kwenza ukuxhuma nokunika amandla amadivayisi abe lula futhi asebenze kahle ezindaweni eziningi.
I-PoE iwukhiye ekusetheni inethiwekhi, ihlinzeka ngendlela elula nethengekayo yokunika amandla amadivayisi. Lokhu kufaka amakhamera we-IP, izindawo zokufinyelela ezingenantambo, amafoni e-VoIP, nezinzwa ezihlakaniphile.
I-PoE ivumela ukushintshwa kwe-Ethernet noma amanye amadivayisi wamandla egiye lenethiwekhi ngokuqondile. Lokhu kusho ukuthi asikho isidingo semithombo yamandla engeziwe noma ama-adaptha. Kwenza ukusetha kube lula, kwehlise ukonakaliswa, futhi kukhuphule ukusebenza kahle kwenethiwekhi, ikakhulukazi lapho izindawo zokuphuma kukagesi okunzima ukuzithola.

Isebenza kanjani i-PoE?
| I-PoE Standard | Ubuningi bokulethwa kwamandla |
| 802.3af (PoE) | 15.4 watts |
| 802.3at (PoE+) | 30 watts |
| 802.3bt (PoE++) | 90 watts |
Amazinga we-PoE kanye nezigaba
IEEE 802.3af (PoE)
Izinga le-IEEE 802.3af, elibuye laziwe nge-PoE, libe yingoma yokuqala enkulu. Ivumela amadivayisi ukuthi afinyelele ku-15.4 watts wamandla, okungenani ngama-watts angu-12.95 wedivayisi ngokwayo.
IEEE 802.3at (PoE+)
I-IEEE 802.3at ejwayelekile, noma i-PoE+, inyuse amandla ama-watts angu-30. Lokhu kusho ukuthi amadivayisi afana namakhamera we-PTZ kanye nezindawo zokufinyelela ezingenantambo angathola amandla engeziwe.
IEEE 802.3bt (PoE++ noma 4PPoE)
Izinga lakamuva, i-IEEE 802.3bt, noma i-PoE++ noma i-4PPoE, liya phambili nakakhulu. Ivumela amandla afinyelela kwangu-90, iyenze ifanelekele amadivayisi anamandla amakhulu njengezibani ze-LED namagiya ezimboni.
Amakilasi Amandla Nemininingwane Yawo
Amazinga e-PoE anezigaba zamandla ahlukene. Lawa makilasi asukela ku-Class 0 kuye ku-Class 8, ngalinye linebanga lalo lamandla. Nali ithebula elibonisa imininingwane yamandla ekilasi ngalinye:
| Ikilasi lamandla | Amandla Aphezulu Emthonjeni Wamandla | Amandla Aphansi Kudivayisi Enamandla |
| Ikilasi 0 | 15.4 W | 0.44 W - 12.95 W |
| Ikilasi 1 | 4 phakathi | 0.44 W - 3.84 W |
| Ikilasi lesi-2 | 7 W | 3.84 W - 6.49 W |
| Ikilasi lesi-3 | 15.4 W | 6.49 W - 12.95 W |
| Ikilasi lesi-4 | 30 W | 12.95 W - 25.5 W |
| Ikilasi lesi-5 | 45 w | 25.5 W - 40 W |
| Ikilasi lesi-6 | 60W | 40 W - 51 W |
| Ikilasi lesi-7 | 75 w | 51 W - 62 W |
| Ikilasi lesi-8 | 90W | 62 W - 71 W |
Izicelo ze-PoE: Amadivayisi we-PoE
Amandla phezu kwe-Ethernet (PoE) ubuchwepheshe manje bujwayelekile ku amanethiwekhi amaningi. Isetshenziswa kumadivayisi ahlukahlukene namasistimu. Kusukela emandleni enkondlo phezu kwemishini ye-ethernet kuya emandleni enkondlo phezu kwezinhlelo zokusebenza ze-ethernet, i-PoE iguqule indlela esinika amandla futhi sixhuma ngayo izingxenye ezahlukene zamandla wezinkondlo phezu kwamasistimu e-ethernet.
Ukusetshenziswa okukhulu kwe-PoE kungaphakathi Amakhamera we-IP nezinhlelo zokugada. Lawa madivayisi athola amandla nedatha ngekhebuli eyodwa ye-Ethernet. Lokhu kwenza ukusetha kube lula futhi kususe isidingo semithombo yamandla engeziwe.
I-PoE nayo ingukhiye ku Voice over IP (VoIP) amafoni. Isiza lawa mafoni asebenze ndawonye ngokushelela emahhovisi. Lokhu kwenza ukuxhumana kube ngcono futhi kube nobunye.
I-PoE ilungele izindawo zokufinyelela ezingenantambo nezinzwa ze-IoT futhi. Lawa mandla we-poe phezu kwemishini ye-ethernet angasethwa noma kuphi ngaphandle kokudinga izindawo zikagesi. Lokhu kungenxa yokuthi i-PoE ithumela kokubili idatha namandla ngekhebuli eyodwa ye-Ethernet. Ilungele izakhiwo ezihlakaniphile, izindawo zezimboni, nezinhlelo ze-IoT.
| Idivayisi ene-PoE | Isicelo |
| Amakhamera we-IP | Izinhlelo zokugada nezokuphepha |
| Amafoni e-VoIP | Ukuxhumana okuhlanganisiwe ezindaweni zasehhovisi |
| Amaphoyinti Okungena Okungenantambo | Ukuxhumana okungenantambo ezakhiweni ezihlakaniphile namanethiwekhi e-IoT |
| Izinzwa ze-IoT | Ukuqapha kanye ne-automation kuzilungiselelo zezimboni nezentengiso |
Izinzuzo Zokusebenzisa i-PoE
I-PoE, noma Amandla phezu kwe-Ethernet, ubuchwepheshe benethiwekhi obunezinzuzo eziningi. Kwenza ukufakwa kube lula futhi kukhuphule ukusebenza kahle kwamandla. Lokhu kuyenza ibe ukukhetha okuphezulu kokunika amandla amadivayisi kumanethiwekhi.
Amandla enkondlo eyodwa enkulu phezu kwenzuzo ye-ethernet iletha idatha namandla ngekhebula ye-Ethernet eyodwa. Lokhu kwehlisa imfuhlumfuhlu futhi kwenza ukusetha kube lula. Futhi, ukusebenza kahle kwamandla kwenkondlo kusho ukusetshenziswa kwamandla okuncane, ukonga imali ngokuhamba kwesikhathi.
Amanye amandla enkondlo phezu kwenzuzo ye-ethernet yiwo ukuguquguquka. Amadivayisi angaya lapho edingeka khona, ngaphandle kokudinga izindawo zikagesi. Lokhu kuvumelana nezimo kuhle ekusetheni izindawo zokufinyelela okungenantambo, amakhamera we-IP, namafoni e-VoIP.
Okokugcina, poe ukuphumelela kwezindleko i-plus enkulu. Yonga ezindlekweni zokufaka nokugcina ngokungadingi amasistimu kagesi ahlukene. Lokhu kwenza i-PoE ihehe kuzo zonke izinhlobo zamabhizinisi, amakhulu noma amancane.
Ukusebenzisa i-PoE kungenza ukusethwa kwenethiwekhi kube lula, kuthuthukise ukusetshenziswa kwamandla, futhi konge imali. Kuyisinqumo esihlakaniphile sezinhlelo zokusebenza eziningi.
