POE Power Over Ethernet ke eng? - Tataiso ea Theknoloji ea Marang-rang
Power over Ethernet (PoE) ke theknoloji e fetolang papali bakeng sa marang-rang a sejoale-joale. E lumella data le matla ho phalla ka thapo e le 'ngoe ea Ethernet. Sena se etsa hore lisebelisoa tsa ho hokahanya le ho kenya matla li be bonolo le ho sebetsa hantle libakeng tse ngata.
PoE ke senotlolo sa ho seta marang-rang, e fana ka mokhoa o bonolo le o theko e tlase oa lisebelisoa tsa motlakase. Sena se kenyelletsa lik'hamera tsa IP, libaka tsa phihlello tse se nang mohala, mehala ea VoIP, le lisensara tse bohlale.
PoE e lumella li-switch tsa Ethernet kapa lisebelisoa tse ling tsa motlakase tsa marang-rang ka kotloloho. Sena se bolela hore ha ho hlokahale mehloli e eketsehileng ea matla kapa li-adapter. E etsa hore ho seta ho be bonolo, ho fokotsa bohlasoa, le ho matlafatsa ts'ebetso ea marang-rang, haholo-holo moo ho leng thata ho fumana lisebelisoa tsa motlakase.

PoE e Sebetsa Joang?
| PoE Standard | Boholo ba Phano ea Matla |
| 802.3af (PoE) | 15.4 watts |
| 802.3at (PoE+) | 30 watts |
| 802.3bt (PoE++) | matla a 90 watts |
Maemo a PoE le Lihlopha
IEEE 802.3af (PoE)
Tekanyetso ea IEEE 802.3af, eo hape e tsejoang e le PoE, e bile eona ntho ea pele e kholo. E lumella lisebelisoa hore li fihle ho li-watts tse 15.4 tsa matla, bonyane li-watts tse 12.95 bakeng sa sesebelisoa ka boeona.
IEEE 802.3at (PoE+)
IEEE 802.3at standard, kapa PoE+, e phahamisitse matla ho li-watts tse 30. Sena se bolela hore lisebelisoa tse kang lik'hamera tsa PTZ le libaka tsa ho kena ka waelese li ka fumana matla a mangata.
IEEE 802.3bt (PoE++ kapa 4PPoE)
Tekanyetso ea morao-rao, IEEE 802.3bt, kapa PoE++ kapa 4PPoE, e tsoela pele le ho feta. E lumella matla a fihlang ho li-watts tse 90, e etsa hore e be e loketseng lisebelisoa tsa matla a phahameng joalo ka mabone a LED le lisebelisoa tsa indasteri.
Lihlopha tsa Matla le Litlhaloso tsa tsona
Litekanyetso tsa PoE li na le lihlopha tse fapaneng tsa matla. Lihlopha tsena li tloha ho Sehlopha sa 0 ho ea ho 8, se seng le se seng se na le matla a sona. Mona ke tafole e bonts'ang lintlha tsa matla bakeng sa sehlopha ka seng:
| Sehlopha sa Matla | Boholo ba Matla Mohloling oa Matla | Bonyane ba Matla ho Sesebelisoa se Matla |
| Sehlopha sa 0 | 15.4 W | 0,44 W - 12,95 W |
| Sehlopha sa 1 | 4 ho | 0,44 W - 3,84 W |
| Sehlopha sa 2 | 7 W | 3,84 W - 6,49 W |
| Sehlopha sa 3 | 15.4 W | 6,49 W - 12,95 W |
| Sehlopha sa 4 | 30 W | 12,95 W - 25,5 W |
| Sehlopha sa 5 | 45 W | 25,5 W - 40 W |
| Sehlopha sa 6 | 60 W | 40 W - 51 W |
| Sehlopha sa 7 | 75 W | 51 W - 62 W |
| Sehlopha sa 8 | 90 W | 62 W - 71 W |
Lisebelisoa tsa PoE : Lisebelisoa tsa PoE
Matla holim'a theknoloji ea Ethernet (PoE) e se e tloaelehile ho marang-rang a mangata. E sebelisoa ka mefuta e fapaneng ea lisebelisoa le litsamaiso. Ho tloha ho matla a thothokiso holim'a lisebelisoa tsa ethernet ho ea ho matla a poe holim'a lits'ebetso tsa ethernet, PoE e fetotse tsela eo re matlafatsang le ho hokahanya likarolo tse fapaneng tsa matla a poe holim'a litsamaiso tsa ethernet.
Tšebeliso e 'ngoe e kholo ea PoE ke ho Likh'amera tsa IP le lits'ebetso tsa ho lebela. Lisebelisoa tsena li fumana matla le data ka thapo e le 'ngoe ea Ethernet. Sena se nolofalletsa ho seta mme se tlosa tlhoko ea mehloli e meng ea matla.
PoE e boetse e bohlokoa ho Voice over IP (VoIP) mehala. E thusa lifono tsena ho sebetsa 'moho ka thelelo liofising. Sena se etsa hore puisano e be betere hape e momahane.
PoE e ntle bakeng sa libaka tsa ho kena ka waelese le li-sensor tsa IoT hape. Matla ana a poe holim'a lisebelisoa tsa ethernet li ka hlophisoa kae kapa kae ntle le ho hloka lisebelisoa tsa motlakase. Sena ke hobane PoE e romella data le matla ka thapo e le 'ngoe ea Ethernet. E loketse meaho e bohlale, libaka tsa indasteri le lits'ebetso tsa IoT.
| Sesebelisoa sa PoE-Powered | Kopo |
| Lik'hamera tsa IP | Litsamaiso tsa ho lebela le ts'ireletso |
| Lifono tsa VoIP | Puisano e kopaneng maemong a liofisi |
| Wireless Access Points | Khokahano e se nang mohala meahong e bohlale le marang-rang a IoT |
| Li-Sensors tsa IoT | Tlhokomelo le boiketsetso maemong a indasteri le a khoebo |
Melemo ea ho Sebelisa PoE
PoE, kapa Power over Ethernet, ke theknoloji ea marang-rang e nang le melemo e mengata. E nolofatsa ho kenya le ho matlafatsa matla a matla. Sena se etsa hore e be khetho e holimo bakeng sa lisebelisoa tsa motlakase ho marang-rang.
E 'ngoe e kholo ea matla a thothokiso holim'a phaello ea ethernet ke ho fana ka data le matla ka thapo e le 'ngoe ea Ethernet. Sena se fokotsa bohlasoa mme se nolofalletsa ho seta. Ho feta moo, matla a poe a bolela tšebeliso e fokolang ea matla, ho boloka chelete ka nako e telele.
E 'ngoe ea matla a thothokiso holim'a molemo oa ethernet ke eona tenyetseha. Lisebelisoa li ka ea moo li hlokoang, ntle le ho hloka lisebelisoa tsa motlakase. Sena se bonolo bakeng sa ho theha libaka tsa phihlello tse se nang mohala, lik'hamera tsa IP, le mehala ea VoIP.
Qetellong, poe ho baballa litšenyehelo ke tlatsetso e kholo. E boloka litšenyehelo tsa ho kenya le ho boloka ka ho se hloke lisebelisoa tse arohaneng tsa motlakase. Sena se etsa hore PoE e ipiletse ho mefuta eohle ea likhoebo, tse kholo kapa tse nyane.
Ho sebelisa PoE ho ka nolofatsa ho seta marang-rang, ho ntlafatsa tšebeliso ea matla le ho boloka chelete. Ke khetho e bohlale bakeng sa lits'ebetso tse ngata.
