Li-switches li atisa ho sebelisoa mererong e fokolang ea hona joale, haholo-holoLiphetoho tsa POE.POE e boetse e bitsoa sistimi ea phepelo ea motlakase e thehiloeng sebakeng sa lehae (POL, Power over LAN) kapa Active Ethernet (Active Ethernet), eo ka linako tse ling e bitsoang Power over Ethernet.Ena ke lintlha tsa morao-rao tsa maemo a morao-rao bakeng sa ho fetisetsa data le matla a motlakase ka nako e le 'ngoe ho sebelisoa lithapo tsa phetisetso tsa Ethernet tse tloaelehileng,' me li boloka ho lumellana le litsamaiso le basebelisi ba teng ba Ethernet.Joale, re khetha switch ea POE joang?

1. Nahana ka matla a thepa ea hau

Ka mokhoa o ts'oanang, khetha switch ea PoE e nang le matla a holimo.Haeba matla a sesebelisoa sa hau a le ka tlase ho 15W, joale khetha switch ea PoE e tšehetsang maemo a 802.3af.Haeba matla a le kholo ho feta 15W, khetha sesebelisoa sa matla a phahameng se nang le 802.3at standard.Hajoale, li-switches tse ngata tsa PoE li tšehetsa af le ho, kahoo ela hloko haholo ha u reka.

2. Boema-kepe ba 'mele

Pele ho tsohle, hoa hlokahala ho tseba palo ea li-switch interfaces, palo ea likou tsa optical fiber, tsamaiso ea marang-rang, lebelo (10/100/1000M) le litaba tse ling.Hajoale, marang-rang a 'marakeng ke boholo ba likou tse 8, 12, 16 le 24.Ka kakaretso ho na le kou e le 'ngoe kapa tse peli tsa optical fiber,' me u tlameha ho ela hloko hore na boema-kepe ba optical ke 100M kapa 1000M.E itšetlehile ka boemo.

Li-switches tsa PoE hangata li sebelisoa ho hokela li-terminals tse nang le motlakase 'me li sebelisoa e le li-switches.Nahana ka palo ea likou tsa phepelo ea motlakase tsa PoE tse tšehetsoeng ke switch ho latela palo ea lisebelisoa tsa terminal tse nang le motlakase.Ntle le moo, ho boetse hoa hlokahala ho nahana ka sekhahla se phahameng seo boema-kepe bo hlokang ho ts'ehetsa ho latela terminal e tsamaisoang le litlhoko tsa nnete.Mohlala, haeba kou ea AP e le Gigabit 'me e sebelisa 11AC kapa li-dual-band, phihlello ea Gigabit e ka nahanoa.

3. Mekhahlelo ea phepelo ea matla

Khetha sesebelisoa se loketseng ho latela protocol ea phepelo ea motlakase (joalo ka 802.3af, 802.3at kapa PoE e sa tloaelehang) e tšehetsoang ke terminal e tsamaisoang ke motlakase (AP kapa IP khamera).Protocol ea phepelo ea motlakase ea PoE e tšehelitsoeng ke switch e tlameha ho lumellana le terminal e tsamaisoang ka matla.Ho na le likotsi tse ngata tsa polokeho ho li-switches tse sa tloaelehang tsa PoE.Ho khothalletsoa hore u leke ho khetha lisebelisoa tse tloaelehileng tsa 48V PoE.

4. Wiring scheme

Basebelisi ba ka bapisa le ho bala litšenyehelo tsa lithapo tsa phepelo ea motlakase sebakeng sa heno le litšenyehelo tsa ho sebelisa switch ea PoE bakeng sa phepelo ea motlakase.Hajoale, sebaka sa phepelo ea motlakase oa li-switches tsa PoE se ka har'a limithara tse 100.Ha ho na lithibelo tsa moralo, tse ka bolokang chelete e ka bang 50% ea litšenyehelo tsohle.Wiring ka har'a limithara tse 100 e ka atolosa marang-rang ntle le ho thibeloa ke moralo oa lithapo tsa motlakase.Hang ha li-AP tse se nang mohala, lik'hamera tsa marang-rang le lisebelisoa tse ling tsa ho qetela maboteng a phahameng kapa siling bakeng sa katoloso e bonolo, lithapo tse bonolo le ponahalo e ntle.

5. Ts'ehetso ea tekheniki ea pele ho thekiso le kamora ho rekisa
