Furayaasha waxaa badanaa loo isticmaalaa mashaariicda hadda daciifka ah, gaar ahaanDaboolida POE.POE waxa kale oo loo yaqaan nidaamka sahayda korontada ku salaysan ee degaanka (POL, Power over LAN) ama Active Ethernet (Active Ethernet), mararka qaarkood loo yaqaan Power over Ethernet.Kani waa qeexitaan heerkii ugu dambeeyay ee isku mar gudbinta xogta iyo awooda korantada iyadoo la adeegsanayo fiilooyinka gudbinta Ethernet ee jira, waxayna ilaalinaysaa la jaanqaadka nidaamyada iyo isticmaalayaasha Ethernet jira.Haddaba, sidee ayaan u dooranaa beddelka POE?

1. Tixgeli awoodda qalabkaaga

Si la mid ah dooro beddelka PoE oo leh awood sare.Haddii awoodda qalabkaagu ay ka hooseyso 15W, ka dibna dooro beddelka PoE ee taageera heerka 802.3af.Haddii korontadu ay ka weyn tahay 15W, dooro beddelka tamarta sare leh ee 802.3at.Waqtigan xaadirka ah, qaar badan oo ka mid ah furayaasha PoE waxay taageeraan af iyo at labadaba, markaa fiiro gaar ah u yeelo markaad wax iibsaneyso.

2. Deked jireed

Ugu horreyntii, waxaa lagama maarmaan ah in la go'aamiyo tirada is-beddelka is-beddelka, tirada dekedaha fiber-ka, maareynta shabakadda, xawaaraha (10/100/1000M) iyo arrimo kale.Waqtigan xaadirka ah, interfaces-yada suuqyadu waxay u badan yihiin 8, 12, 16, iyo 24 dekedood.Guud ahaan waxaa jira hal ama laba dekedood oo fiber optic ah, waana inaad fiiro gaar ah u yeelataa inay dekedda indhaha ahi tahay 100M ama 1000M.Waxay ku xiran tahay xaaladda.

Furayaasha PoE ayaa guud ahaan loo isticmaalaa in lagu xidho terminal awood leh waxaana loo isticmaalaa furayaasha gelitaanka.Tixgeli tirada dekedaha sahayda korantada ee PoE ee uu taageeray shiduhu marka loo eego tirada aaladaha terminalka ku shaqeeya.Intaa waxaa dheer, sidoo kale waa lagama maarmaan in la tixgeliyo heerka ugu sarreeya ee dekeddu u baahan tahay inay taageerto iyada oo loo eegayo terminalka tamarta iyo baahiyaha dhabta ah.Tusaale ahaan, haddii dekedda AP ay tahay Gigabit oo ay isticmaasho 11AC ama dual-band, helitaanka Gigabit waa la tixgelin karaa.

3. Halbeegyada sahayda korontada

Dooro beddelka ku habboon sida uu dhigayo hab-maamuuska korantada (sida 802.3af, 802.3at ama PoE-da aan caadiga ahayn) ee ay taageerto terminaalka tamarta leh (AP ama IP camera).Nidaamka sahayda korantada ee PoE ee uu taageeray shiduhu waa in uu la socdaa terminalka tamarta leh.Waxaa jira khataro badan oo badbaado oo suurtagal ah oo ku jira furayaasha PoE ee aan caadiga ahayn.Waxaa lagugula talinayaa inaad isku daydo inaad doorato heerka caadiga ah ee 48V PoE.

4. Nidaamka fiilooyinka

Isticmaalayaasha ayaa is barbardhigi kara oo xisaabin kara qiimaha xargaha korontada ee terminalka iyo qiimaha isticmaalka qalabka korontada ee PoE.Waqtigan xaadirka ah, masaafada korantada ee furayaasha PoE waxay u jirtaa 100 mitir.Ma jiraan xaddidaadyo qaabeynta, taas oo badbaadin karta qiyaastii 50% qiimaha guud.Xadhkaha gudaha 100 mitir waxay si dabacsanaan leh u ballaarin kartaa shabakada iyada oo aan la xaddidin qaabka xadhkaha korontada.Ku xidh AP-yada bilaa-waayirka ah, kamaradaha isku-xidhka iyo qalabka kale ee ka baxa gidaarada sare ama saqafka si loo balaadhiyo dabacsanaan, fiilooyin fudud, iyo muuqaal qurxoon.

5. Iibinta ka hor iyo ka dib iibinta taageerada farsamada

Dooro baayacmushtar la isku halayn karo si aad u heshid adeegyo iib ka hor iyo iibka ka dib
