Kwihlabathi lanamhlanje eliqhagamshelweyo, isiseko senethiwekhi esithembekileyo nesisebenzayo sibalulekile kumashishini nakubaqhubi. Iswitshi se-POE sesinye sezona zinto zibalulekileyo ezidlala indima ebalulekileyo kunxibelelwano lwenethiwekhi. Iiswitshi ze-PoE zamkela ubuchwepheshe obuphambili kwaye zilandela imigangatho yeshishini ukubonelela abaqhubi nge-EPON OLT edibeneyo kakhulu, enomthamo ophakathi, okwenza kube lukhetho olufanelekileyo kwiinethiwekhi zokufikelela kunye neenethiwekhi zekhampasi yeshishini. Kule bhlog, siza kuhlola indlela iiswitshi ze-POE ezinokwandisa ngayo ukusebenza kwenethiwekhi, iimfuno zazo zobugcisa, kunye neenzuzo ezizisa kumashishini.
Inkcazo kunye nomsebenzi weswitshi ye-POE:
Utshintsho lwe-POEsisifinyezo seswitshi sePower over Ethernet, esisixhobo esidibanisa imisebenzi yokuhambisa idatha kunye nombane kwiyunithi enye. Zenzelwe njengee-EPON OLTs ezidityaniswe kakhulu, ezinomthamo ophakathi, ezihambelana nemigangatho yobugcisa ye-IEEE802.3 ah kwaye zihlangabezana neemfuno zezixhobo ze-YD/T 1945-2006 EPON OLT. Ezi switshi zibonelela ngokulula nangokulula ngokuphelisa imfuneko yentambo yombane eyahlukileyo, ukwandisa ukusebenza kakuhle kunye nokunciphisa iindleko.
Iimfuno zobugcisa kunye nokuvuleleka:
Uphuhliso lweeswitshi ze-POE lunika ingqalelo enkulu kwiimfuno zobugcisa. Zilandela umgangatho we-Ethernet Passive Optical Network (EPON), ziqinisekisa ukuhlanganiswa okungenamthungo neenkqubo zenethiwekhi ezikhoyo. Ukongeza, zenzelwe ukuhlangabezana neemfuno zobugcisa ze-EPON 3.0 ezimiselwe yiChina Telecom. Iiswitshi ze-POE zilandela le migangatho, zivulelekile kakuhle, kwaye zinokudityaniswa ngokulula kwaye zihambelane nezixhobo ezahlukeneyo zenethiwekhi.
Umthamo omkhulu, ukuthembeka okuphezulu:
Uphawu oluphambili lwee-POE switches kukuba zinamandla amakhulu, nto leyo eyonyusa ukuguquguquka njengoko inethiwekhi ikhula. Amashishini anokwandisa iziseko zawo zenethiwekhi ngaphandle kokukhathazeka malunga nomthamo olinganiselweyo. Ukongeza, ii-POE switches zinokuthembeka okuphezulu ukuqinisekisa uqhagamshelo olungaphazanyiswayo kwizicelo ezibalulekileyo kunye nokunciphisa ixesha lokungasebenzi. Olu zinzo lubalulekile kumashishini axhomekeke kakhulu kuqhagamshelo lwenethiwekhi kwimisebenzi yemihla ngemihla.
Le software inemisebenzi epheleleyo kunye nokusetyenziswa kwe-bandwidth ephezulu:
Iiswitshi ze-POE zixhotyiswe ngemisebenzi yesoftware ebanzi, evumela abaqhubi ukuba balawule kwaye baphucule iinethiwekhi zabo ngokufanelekileyo. Iimpawu ezifana nenkxaso ye-VLAN, umgangatho wenkonzo (QoS), kunye nolawulo lwethrafikhi zenza amashishini akwazi ukubeka phambili usetyenziso olubalulekileyo kwaye aqinisekise ukusetyenziswa kakuhle kwe-bandwidth. Olu phawu lubonelela ngolawulo oluphezulu kunye nokuguquguquka kwithrafikhi yenethiwekhi, nto leyo ephucula ukusebenza kwenethiwekhi iyonke.
Iingenelo zeshishini:
UkubandakanyaIiswitshi ze-POEUkungena kwiziseko zophuhliso lwenethiwekhi kunokuzisa iingenelo ezininzi kumashishini. Okokuqala, inkqubo yokufakela elula inciphisa ubunzima kunye neendleko ezinxulumene neentambo zombane ezahlukeneyo. Okwesibini, ukuguquguquka okuphezulu kunye nokuthembeka kweeswitshi ze-POE kwenza inethiwekhi ikhuseleke kwixesha elizayo kwaye ivumelane nokukhula ngaphandle kokuphazamiseka. Ukongeza, iimpawu zesoftware ziqinisekisa ukusetyenziswa kwe-bandwidth ngokufanelekileyo, zonyusa imveliso kwaye zibonelela ngamava omsebenzisi agudileyo. Okokugqibela, ukwamkela iiswitshi ze-POE kuvumela amashishini ukuba ahlale ethobela imigangatho yoshishino, okwenza kube lula ukudibanisa nezinye iinkqubo kunye nezixhobo.
ukuququmbela:
Ukuhlanganiswa kwee-POE switches kwiziseko zophuhliso lwenethiwekhi kuzise iingenelo ezinkulu kubaqhubi kunye namashishini. Ezi switches zibonelela ngeempawu ezahlukeneyo ezifana nomthamo ophezulu, ukuthembeka okuphezulu, ukusebenza ngokupheleleyo kwesoftware kunye nokusetyenziswa kwe-bandwidth ngokufanelekileyo, ukwandisa ukusebenza kakuhle kwenethiwekhi kunye nokwenza lula inkqubo yokufaka ngelixa kulandelwa imigangatho yoshishino. Ngokutyala imali kwii-POE switches, amashishini anokudala indawo yenethiwekhi eqinileyo neyonganyelwayo exhasa ukukhula kwawo kwaye iqinisekise uqhagamshelo olungenakuphazamiseka kwimeko yanamhlanje yedijithali eguquka ngokukhawuleza.
