Ukuhlolwa kokushintsha kwe-TP-Link nge-PoE yebanga elide. Futhi kancane mayelana nokuthuthukiswa kwamamodeli amadala

Ngaphambilini, sakha ubuchwepheshe be-Power over Ethernet kumaswishi ethu kuphela esiqondisweni sokwandisa amandla adluliswayo. Kodwa ngesikhathi sokusebenza kwezixazululo nge-PoE ne-PoE +, kwaba sobala ukuthi lokhu akwanele. Amakhasimende ethu abhekene hhayi kuphela nokuntuleka kwesabelomali samandla, kodwa futhi nomkhawulo ojwayelekile wamanethiwekhi e-Ethernet - ububanzi bokudlulisa ulwazi lwamamitha angu-100. Kulesi sihloko sizokutshela ukuthi ungazungeza kanjani lo mkhawulo futhi uhlole i-PoE yebanga elide ukuzijwayeza.

Kungani sidinga ubuchwepheshe bebanga elide le-PoE?

Ibanga lamamitha ayikhulu liningi. Ngaphezu kwalokho, empeleni ikhebula alilokothi libekwe emgqeni oqondile: udinga ukuzungeza wonke ama-bends wesakhiwo, ukuphakama noma ukuwa kusuka esiteshini esisodwa kuya kwesinye, njalonjalo. Ngisho nasemabhilidini aphakathi nendawo, umkhawulo wobude bengxenye ye-Ethernet ungashintsha ube yikhanda elibuhlungu kumlawuli. 

Sinqume ukusebenzisa isibonelo sesakhiwo sesikole ukuze sibonise ngokucacile ukuthi yimaphi amadivaysi azokwazi ukuthola ugesi esebenzisa i-PoE futhi axhume kunethiwekhi (izinkanyezi eziluhlaza), futhi angeke (izinkanyezi ezibomvu). Uma imishini yenethiwekhi ingakwazi ukufakwa phakathi kwamacala, lapho-ke lapho amadivaysi eqina kakhulu ngeke akwazi ukuxhuma:

Ukweqa umkhawulo webanga, kusetshenziswa ubuchwepheshe be-Long Range PoE: bukuvumela ukuthi unwebe indawo yokumboza yenethiwekhi enezintambo futhi uxhume ababhalisile abatholakala ebangeni elingafika kumamitha angama-250. Uma usebenzisa i-Long Range PoE, idatha nogesi kudluliselwa ngezindlela ezimbili:

1. Uma ijubane le-interface liyi-10 Mbps (i-Ethernet evamile), khona-ke ukudluliswa kanyekanye kwakho kokubili amandla nedatha kungenzeka kumasegimenti afika kumamitha angu-250 ubude.
2. Uma isivinini sokusebenzelana sisethelwe ku-100 Mbps (kumamodeli TL-SL1218MP kanye ne-TL-SG1218MPE) noma i-1 Gbps (yemodeli TL-SG1218MPE), akukho ukudluliswa kwedatha okuzokwenzeka - ukudluliswa kwamandla kuphela. Kulesi simo, enye indlela yokudlulisa idatha izodingeka, isibonelo, umugqa wokubuka ohambisanayo. I-Long Range PoE kulokhu izosetshenziselwa amandla okude kuphela.

Ngakho-ke, lapho usebenzisa i-Long Range PoE endaweni yesikole esifanayo, imishini yenethiwekhi esekela isivinini se-10 Mbps ingatholakala kunoma iyiphi indawo.

 

Imaphi amaswishi asekela i-Long Range PoE angayenza

Umsebenzi we-Long Range PoE utholakala kumaswishi amabili emugqeni we-TP-Link: I-TL-SG1218MPE и I-TL-SL1218MP.

I-TL-SL1218MP iyiswishi engaphethwe. Inamachweba angu-16, isabelomali sayo se-PoE siphelele ngu-192 W, esivumela ukuthi inikeze amandla afinyelela ku-30 ​​W ngembobo ngayinye. Uma isabelomali samandla singeqiwe, zonke izimbobo ze-16 Fast Ethernet zingathola amandla.  

Ukucushwa kwenziwa kusetshenziswa amaswishi kuphaneli yangaphambili: eyodwa ivula imodi ye-PoE ye-Long Range, kanti eyesibili ilungisa okubalulekile kwamachweba lapho kusatshalaliswa isabelomali samandla sokushintshwa. 

I-TL-SG1218MPE ingeyamaswishi e-Easy Smart. Ungaphatha idivayisi ngokusebenzisa isixhumi esibonakalayo sewebhu noma izinsiza ezikhethekile. 

Esigabeni se-System interface, abalawuli banokufinyelela ekusebenzeni okujwayelekile okujwayelekile: ukushintsha ukungena ngemvume nephasiwedi ye-akhawunti yomqondisi, ukusetha ikheli le-IP lemojula yokulawula, ukuvuselela i-firmware, njalonjalo.

Izindlela zokusebenza zembobo zisethwe esigabeni Ukushintsha → Ukusethwa Kwembobo. Usebenzisa amathebhu asele esigaba, ungakwazi ukunika amandla/ukukhubaza i-IGMP futhi uhlanganise ukuxhumana okubonakalayo kube amaqembu.

Isigaba Sokuqapha sihlinzeka ngolwazi lwezibalo mayelana nokusebenza kwezimbobo zokushintshwa. Ungakwazi futhi ukufanisa ithrafikhi, unike amandla noma ukhubaze ukuvikelwa kwe-loop, futhi uqalise isihloli sekhebula esakhelwe ngaphakathi.

Iswishi ye-TL-SG1218MPE isekela izindlela ezimbalwa zenethiwekhi ebonakalayo: ukumaka okungu-802.1q, i-VLAN esekelwe embobeni, ne-MTU VLAN. Uma usebenza kumodi ye-MTU VLAN, ukushintshwa kuvumela kuphela ukushintshaniswa kwethrafikhi phakathi kwamachweba omsebenzisi kanye nesixhumi esibonakalayo se-uplink, okungukuthi, ukushintshaniswa kwethrafikhi phakathi kwezimbobo zomsebenzisi kuvinjelwe ngokuqondile. Lobu buchwepheshe bubizwa nangokuthi i-Asymmetric VLAN noma i-Private VLAN. Isetshenziselwa ukuthuthukisa ukuphepha kwenethiwekhi ukuze kuthi lapho kuxhunywe ngokoqobo ekushintsheni, umhlaseli angeke akwazi ukubamba ukulawula okokusebenza.

Esigabeni se-QoS, ungabeka kuqala isikhombimsebenzisi, ulungiselele imikhawulo yesivinini sethrafikhi yomsebenzisi, futhi ubhekane nezivunguvungu.

Esigabeni se-PoE Config, umlawuli angakhawulela ngamandla amandla amakhulu atholakala kumthengi othile, abeke ukubaluleka kwamandla esixhumi esibonakalayo, axhume noma anqamule umthengi.

Ukuhlola Ibanga Elide

Ku-TL-SL1218MP sivumele ukusekelwa kwe-Long Range kumachweba ayisishiyagalombili okuqala. Ifoni yethu ye-IP yokuhlola isebenze ngempumelelo. Ngokusebenzisa izilungiselelo zefoni, sithole ukuthi isivinini esivunyelwene ngaso yi-10 Mbps. Sibe sesivula iswishi ye-Long Range PoE sathi Valiwe futhi sabheka ukuthi kwenzekeni ocingweni lokuhlola ngemuva kwalokho. Idivayisi iqale ukusebenza ngempumelelo futhi yabikwa isebenzisa imodi engu-100 Mbps kunethiwekhi yayo, kodwa idatha ayizange idluliselwe esiteshini futhi nefoni ibingabhalisiwe esiteshini. Ngakho-ke, ukunika amandla abathengi abaxhunywe kumashaneli amade e-Ethernet kungenzeka ngaphandle kokuvula imodi ye-Long Range PoE, kodwa kulokhu amandla kuphela azodluliselwa ngesiteshi, hhayi idatha.

Emandleni ajwayelekile phezu kwemodi ye-Ethernet (lapho ubude besegimenti bungadluli amamitha angu-100), ukudluliswa kwamandla nedatha kwenzeka ngesivinini esifika ku-1 Gbps ehlanganisiwe. Ukuhlola ukusebenza kocingo oluxhaswe yi-PoE futhi luxhunywe ngentambo yobude obuphelele kube yimpumelelo.

Kushintsho lwe-TL-SG1218MPE sishintshe imbobo kumodi ye-10 Mbps Half Duplex - idivayisi ixhumeke ngempumelelo.

Ngokwemvelo, besifuna ukwazi ukuthi mangakanani amandla asetshenziswa ifoni ngalolu xhumo, kwavela ukuthi bekuyi-1,6 W kuphela.

Kodwa uma ushintsha isixhumi esibonakalayo sokushintsha siye ku-100 Mbps Half Duplex noma 100 Mbps Full Duplex mode yokusebenza, ukuxhumana nefoni kulahleka ngokushesha futhi akubuyiselwa.

I-interface ngokwayo isesimweni se-Link Down.

Cishe into efanayo yenzeka uma isixhumi esibonakalayo sishintshelwa kujubane elizenzakalelayo kanye nemodi ye-duplex yokuxoxisana. Ngakho-ke, okuwukuphela kwendlela yokusebenzisa izingxenye ezinde ze-Ethernet ukusetha ngesandla isivinini sokuxhuma sibe ngu-10 Mbps.

Ngeshwa, amasegimenti ekhebula amade awatholwa isihloli sekhebula esakhelwe ngaphakathi.

Ibuyekeza amanye amaswishi e-PoE

Njengoba inani lamadivayisi anikwe amandla yi-PoE lihlala likhula, sibuyekeze ukunikezwa kwamandla kwamamodeli amadala. Manje, esikhundleni sokunikezwa kwamandla ka-110 W kanye no-192 W, wonke amamodeli azoba namayunithi angu-150 W kanye namayunithi angu-250 W. Zonke lezi zinguquko zingabonakala kuthebula:

Njengoba ubuchwepheshe be-PoE buqala ukungena ezingeni labathengi, olunye ushintsho ohlwini lwaba ukwethulwa kwamaswishi aklanyelwe amahhovisi amancane nokusetshenziswa kwasekhaya.

Ngo-2019, amamodeli avele kulayini wokushintshwa kwe-Fast Ethernet okungalawulwa I-TL-SF1005P и I-TL-SF1008P kumachweba angu-5 no-8. Isabelomali samandla samamodeli singama-58 W, futhi singasatshalaliswa phakathi kokuxhumana okune (kufika ku-15,4 W ngembobo ngayinye). Amaswishi awanawo abalandeli; angabekwa ngqo ehhovisi nasezindaweni zokusebenza, ezindlini futhi asetshenziselwe ukuxhuma noma yimaphi amakhamera we-IP namafoni we-IP. Ukushintsha kungabeka phambili ukusatshalaliswa kwamandla: uma ukugcwala ngokweqile kwenzeka, amadivayisi angabalulekile kakhulu ayavalwa.

Amamodeli I-TL-SG1005P и I-TL-SG1008P, njengamamodeli we-SF, aklanyelwe ukufakwa kwedeskithophu, kodwa anomshini owakhelwe ngaphakathi we-gigabit, okuvumela ukuthi uxhume imishini yesiphetho enesivinini esiphezulu esekela i-802.3af. 

Shintsha I-TL-SG1008MP Ingabekwa kokubili etafuleni nasendaweni yokubeka. Le modeli inezimbobo ze-Gigabit Ethernet eziyisishiyagalombili, ngalinye elingaxhunywa kumthengi nge-IEEE 802.3af/ngokusekelwa kanye namandla afika ku-30 ​​W. Isamba sesabelomali samandla esisetshenziswa ngu-126 W. Isici esikhethekile sokushintsha ukuthi isekela imodi yokonga amandla, lapho iswishi ikhala ngezikhathi ezithile izimbobo zayo futhi ivale amandla uma ingekho idivayisi exhunyiwe. Lokhu kukuvumela ukuthi wehlise ukusetshenziswa kwamandla ngo-75%. 

Ngokungeziwe ku-TL-SG1218PE, ulayini we-TP-Link wamaswishi aphethwe uhlanganisa amamodeli I-TL-SG108PE и I-TL-SG1016PE. Banesabelomali esiphelele samandla sedivayisi - 55 W. Lesi sabelomali singasatshalaliswa kabusha kuzo zonke izimbobo ezine kuze kufike ku-15,4 W wamandla okukhiphayo ngembobo ngayinye. Lezi zinguquko zine-firmware efanayo ne-TL-SG1218PE, ngokulandelana, futhi imisebenzi iyafana: ukuqapha inethiwekhi, ukubeka phambili ithrafikhi, i-QoS, i-MTU VLAN.

Incazelo ephelele yebanga ledivayisi ye-TP-Link PoE iyatholakala kokuthi isixhumanisi.
