Kwintsimi yokuhlola ukhuseleko, izixhobo ezininzi zenethiwekhi ezisetyenziswayo ngoku zixhasa unikezelo lombane lwe-PoE. Kulwakhiwo lokubeka iliso kwinethiwekhi, ukuze kuncitshiswe iindleko zocingo kunye nokwenza kube lula kwaye ngokukhawuleza, uninzi lweenkampani zobunjineli ziya kuqwalasela ukusebenzisa umbane we-PoE, oko kukuthi, ukusebenzisa iiswitshi ze-PoE kwiikhamera zokucupha amandla. Ke, zingaphi izixhobo ezinokubonelelwa ngombane wePoE kwishishini?

1. Umgangatho wokunikezelwa kwamandla okutshintsha kwe-PoE

Ukubona ukuba zingaphi iikhamera ezinokuthi zinikwe amandla ngokutshintsha kwe-PoE ngexesha elifanayo, iinkalo ezimbini kufuneka ziqwalaselwe: umgangatho wokunikezelwa kwamandla ombane we-PoE kunye nokunikezelwa kwamandla ombane we-PoE switch. Ukunikezelwa kwamandla okutshintsha kwe-PoE kunokuqondwa njengombane we-single-port ye-PoE switch. Kukho imigangatho emibini yeeswitshi ze-PoE ezidumileyo kwimarike, IEEE802.3af kunye ne-IEEE802.3at. Umgangatho we-IEEE802.3af uchaza unikezelo lwamandla lwe-15.4W, kwaye umgangatho we-IEEE802.3at uchaza unikezelo lwamandla ukuya kwi-30W. Ngenxa yemigangatho eyahlukeneyo yonikezelo lwamandla, unikezelo lombane lwezibuko elinye lukwahlukile. Ngokomzekelo, amandla ekhamera yi-9W, kwaye i-af standard switch ye-PoE ingasetyenziswa; Ukuba amandla ekhamera angama-20W, kufuneka usebenzise iswitshi ye-PoE eqhelekileyo; ukuba amandla ekhamera angaphezulu kwe-30W, kufuneka usebenzise imodyuli yonikezelo lwamandla e-PoE ukubonelela amandla.

Ngokubanzi, iswitshi ye-PoE exhasa zombini i-af kunye nemigangatho yobonelelo lwamandla inonikezelo lwamandla oluziqhelanisayo. Ngokomzekelo, ukuba iqhagamshelwe kwisixhobo se-5W, inikeza i-5W yamandla; ukuba iqhagamshelwe kwisixhobo se-20W, ke ibonelela nge-20W yamandla.

2. Amandla apheleleyo okutshintsha kwePoE yoshishino

Amandla apheleleyo okutshintsha kwe-PoE yoshishino luphawu olubaluleke kakhulu, oluhambelana ngqo nokuba zingaphi iikhamera ezinokuziswa. Ukuthatha i-PoE ye-24-port kunye nokunikezelwa kwamandla ka-400W, amandla apheleleyo okutshintsha kwe-PoE malunga ne-370W emva kokususa ilahleko.

Ngaphantsi komgangatho we-IEEE802.3af, inokubonelela ngamachweba angama-24 (370 / 15.4 = 24), oko kukuthi, inokunika amandla kwiikhamera ze-24 ngexesha elifanayo, oko kukuthi, ukunikezelwa kwamandla apheleleyo. Kodwa ukuba ibalwa ngokwe-IEEE802.3at kumgangatho we-single-port ubuninzi bonikezelo lwamandla lwe-30W, kwangaxeshanye, inokubonelela kuphela amandla kumazibuko ali-12 kakhulu (370/30=12).

Ekusetyenzisweni kwangempela, ukusetyenziswa kwamandla amaninzi kwiikhamera zewebhu eziqhelekileyo kuphantsi, ngokusisiseko akudluli kwi-15W. Ukuba izibuko le-PoE ngalinye ligcina amandla ngokowona mandla aphezulu (umzekelo, i-30W) ngeli xesha, amanye amazibuko aya kusebenzisa amandla e-PoE. Ayinasiphelo, kodwa amanye amazibuko akakwazi ukusasaza amandla. Umzekelo, ezinye iiswitshi ze-PoE zixhasa ulwabiwo lwamandla aguqukayo, anokuphepha le meko. Xa kuthengwa iswitshi ye-PoE, kuxhomekeke ekubeni utshintshi luxhasa ulwabiwo lwamandla aguquguqukayo, ukuze izibuko ngalinye labele kuphela amandla asetyenziswe ngokwenene, ukuze unikezelo lwamandla ombane we-PoE lunokusetyenziswa ngokufanelekileyo.

3. Ukwabelana ngamava okusebenzisa iiswitshi zamashishini e-PoE

a. Ukusetyenziswa kweeswitshi ezixhasa ukuhanjiswa kwamandla okuguquguqukayo kunokwandisa ukusebenza kakuhle kombane;
b. Okokuqala qonda usetyenziso lwamandla oluphezulu lwesixhobo esinamandla, kwaye emva koko wahlule unikezelo lwamandla lulonke lweswitshi ye-PoE ngowona setyenziso lwamandla luphezulu ukufumana ukuba zingaphi izixhobo ezinokubonelelwa ngePoE.
