Chii Poe-adapteri. Power pamusoro Ethernet

Zvatinosiita ano IT-nyanzvi mhando waya "kusarurama peya", naro hrs zvinogona networked, chakavanzika mukana unoshamisa. Chokwadi ndechokuti kuburikidza navo zvinogona kutapukira kwete chete kune digitaalinen date rukova, asi simba. Poe-adhaputa - okuwedzera mudziyo uyu anofanira kushandiswa. Zvisinei, pane vazhinji akasiyana uye nzira mashoko mano kubatanidza kune zvakarukwa. Ndezvipi chaizvo ari mudziyo?

Basic ruzivo pamusoro mudziyo

Poe-adhaputa - mudziyo ichi, dzinoita mukana Poe-zvigadzirwa unokubvumira uchatamisa Via munhu kwakajairika yakakoswa-vaviri simba kune achida mudziyo. Panyaya iyi, iyo Ethernet-waya Kukwanisa kuchinjana digitaalinen anonongedzera haina akarasika, uye nemambure anonyatsokwanisa dzichipfekeka.

Achiongorora zvaive abbreviations Poe - Power pamusoro Ethernet. Kuti ndiye "simba pamusoro Ethernet mureza." Poe-adhaputa dzimwe nguva vachinzi "injector" - asi mhando mudziyo rechipiri kuchiri dzakarurama kufunga kusiyana wokutanga. Tiri kudzidza zvakananga kushandiswa nhau mudziyo iri akapoteredza kunobatanidza Poe-zvigadzirwa kugona.

Verenga zvimwe pamusoro mabikirwo

Technology Power pamusoro Ethernet unokubvumira kupa simba-siyana mhando mano: Wi-Fi-routers, makamera, okuchengetera namano. The chikuru mukana zvigadzirwa izvi kuti kunosanganisira activation rimwe chete akagadzirwa waya - nokuti zvose digitaalinen yenhepfenyuro anonongedzera, uye nokuda vachigovera magetsi.

Somugumisiro, kugadzwa network hapana chikonzero kuisa waya kuti zvigadziko, uyewo kuisa zvakafanira mamwe magetsi. Mune zvimwe zviitiko, kugadzwa simba netambo anogona kuva kwakaoma nokuda suboptimal chaiko nzvimbo pemambure zvinoriumba. Somuenzaniso, zvinoitika kuti Wi-Fi-adapteri rinopa chiratidzo panguva muimba iyo kuunza magetsi matambudziko. The chete zvinogona kutaurwa pamusoro makamera: dzimwe nguva zvingava zvakakodzera kuongorora nzvimbo dzakaoma kupa simba.

Poe inokwanisa kuronga maererano mano ive nzira yokubudisa, iro rinogona, sezvataona kumusoro, apo goho mudziyo ari paIndaneti uye kushandisa simba pazviri. Izvi zvinogona kushandiswa panyaya upgrading kuitika rezvebonde kwezvivako. Zviri kuunza simba aivapo nehoro chaizvo.

zvakanakira mabikirwo

Saka, kana kuti muchidimbu kiyi zvakanakira michina iri mubvunzo, vanogona vaunze zvinotevera zvawanyora:

- kushandiswa chete waya zvinogoneka zvose kupa simba uye nokuda kupanana digitaalinen mashoko;

- zvikomborero zvinobvira zvoupfumi chokuita kusavapo kudiwa kuisa simba netambo uye nezvimwe zvakafanira midziyo;

- inowana refu azvipire kuchengeteka Network runoenzanirana mhando kwezvivako, nemhaka zvinodiwa nechokwadi zvakafanira kudzivirira yenhengo kuzorwa voltage RINOFAMBIRA;

- pane mukana upgrading kuitika rezvebonde kwezvivako, kukurukurirana sangano munzvimbo dzakanga dzisingambosvikiki kare kuti vanomhanyisa nokuda kudiwa nokuisa dzemagetsi netambo;

- pane mukana kuronga kure kuzvidzora mano vachishandisa Network protocols.

zvino isu kudzidza dzinokosha nemitemo nenheyo izvo anoshanda Poe-Network.

zvinodiwa

The chikuru dzakati ari kubatanidzwa sangano zvakakodzera kwezvivako - IEEE 802.3af. Mwari akaronga kuti zvinosanganisira nemambure mudziyo mhando 2 - manyuko simba uye vatengi. Vanogona kuva, sezvataona kumusoro, Wi-Fi-routers, zvakarukwa okuchengetera namano. Excellent kamera basa rakadaro gadziriro. Pakati inozivikanwa muchiso vagadziri, uchibereka Soup, izvo ingashanda ari Poe-adapteri - Sekaiichi.

Muto wokutanga mhando - manyuko - inogona iri kwokutanga chikamu pomumbure kana pakati Handheld mudziyo kugoverwa Magetsi, uye mutengi. Viewed mureza inoita simba anopa imwe kusarurama peya mhando makirasi siyana unshielded - zvikurukuru vakatsigira 5, 5e uye 6, pane imwe voltage 48 V uye simba kudyiwa pakati 15 watts or. Muchiitiko chino, hapana simba pamusoro chatingatevedzera digitaalinen umbowo kupfuudzwa kubudikidza waya hauna akagovera uye nouchapupu upgrading zviri kuitika rezvebonde kwezvivako ari zvatinoita vanokwanisa haina kutarisirwa.

Nzira kushandisa imwe voltage

Pomumbure, iyo inoshanda maererano Power pamusoro Ethernet mureza, chinogona kupiwa pamwe magetsi kuburikidza nezvirongwa maviri.

Chekutanga, zvinokwanisika kushandisa kwokupedzisira zvikamu mitsetse chiratidzo transformers, kuti semhosva kumusoro. Pomugove voltage rinoshandisirwa pakati pavanoshandisa navo. Saizvozvowo navo, asiwo kugamuchirwa divi, kuti voltage chinobviswa. Michina kwakadaro zvinoita kushandisa chete peya waya kuti nhepfenyuro mukuru-kakawanda zviratidzo, uye kupararira magetsi.

Chechipiri, munhu anogona kushandisa kuti zvinoparadzira simba Kuwanikwa vaviri aripo ari runoenzanirana mhando waya. Izvi zvinokwanisika sei? Chokwadi ndechokuti zviri tsika 2 4 vakaroorana vari Ethernet-waya, hazviwanzoitika rakatangwa. Chokwadi, kana toreva pokuita kwavo 100 Base TX rwokugadzira.

The dzakaona specificity rokuvhiya nomumbure muna Poe pamanyorerwo anotora kuti Kunyanya kushandiswa injectors achavaponesa iyo nzira - kutanga kana wechipiri zvitange voltage. Saka, yaaizova akacherekedza 802.3af mureza anobvumira magetsi hutachiwana kuti peya yerwodzi kana 1,2, semuenzaniso, 4.5 waya. Uyewo injectors zvinogona inoenderana zvizere 100 Base TX rwokugadzira. Zvisinei, kana ine mahwanda, ipapo vanofanira kushanda pamwe chero simba yedzimudzangara zvirongwa dzataurwa pamusoro apa, kunyange kana polarity kwokubatana achashandurwa.

Types Poe-midziyo

Pane zvidzidzo zvinoverengeka zvokushandisa inokwanisa kushanda nesimba yedzimudzangara muoti pamusoro yakakoswa peya. Poe-Adapter - mumwe wavo (unoenderana Soup vane yokuwanda kwemarudzi - tichadzidza specificity yavo). Pamwe naye, munewo Poe-haizoshandisi, uyewo pakuzadza namano. Kakawanda, vanogona kuva revatema kupinda chimwe hurongwa. Ngationei kudzidza chaizvo mumwe nomumwe mhando yasarudzwa zvishandiswa zvakawanda.

unoparadza mano

Unoparadza mano - chokwadi, zvakafanana rezvebonde Soup, iro rine simba pamusoro yakakoswa peya. An maitiro chinokosha vavo - mazano impedance. The runoenzanirana Nhamba kakawanda akatsunga mu kuwanda 19-26,5 ohms. Kazhinji, nemamiriro ezvinhu, izvo zvakabatana mabhodhoro mano, mumwe capacitor kuri chipo.

haizoshandisi

Poe ufambe akagadzirirwa nechokwadi kushanda samambure tichitarisa kuziva yakarurama pamusoro waya riine kuwana pfungwa. Network runoenzanirana mhando basa kwakavakirwa 802.3af dzakati, izvo isu akati apa, uyewo 802.3at. Vanobvumira kugovera kudyidzana dzakasiyana mano maererano zvichibvira simba RINOFAMBIRA. Kana Poe chinja isina kushandiswa, zvingangoita kuti nokuda anongoitika zvakasiyana magetsi ufungisise mudziyo chakamonyana vaviri rotsva.

adapters

Muto iri mhando, sezvataona kumusoro, dzinoiswa pamusoro mamwe marudzi. Saka, Poe-adapteri inogona kugoverwa. In ayo mamiriro, simba wedzerai aripo, uyewo conjugation maatomu akafanana, izvo zvinogona vakapakata nevamwe uye anoonekwa iyi sezvo bhokisi diki kana kuva kwakajairika waya. Power adhaputa ari Poe Chokwadi, dzimwe nguva anonzi ane injector. In musika wokuRussia pane vazhinji ichi mhando mhinduro. Somuenzaniso, vakawanda Adapter Poe TP Link 150S. Chinonyanya kukosha hwokugadzira chakanangana runoenzanirana mhando devaysa - akagadzikana voltage. Optimum waivako anoonekwa kuti 48, kana isu kutaura muenzaniso kuchiratidzwa TP Link.

Rumwe rudzi Poe-adapteri - kutora. Zvisinei, iye, uyewo kusashanda kupa simba mano Via yakakoswa peya, asi avo vasina semhosva pakuzadza chete. Kuti midziyo zvakadaro basa, zviri chinodiwa kuti pakukwanisa kwayo asingatangi pfuura 24 watts or. Zvinogona kucherechedzwa kuti gadziriro mukirasi iyi mano dzinounzwa Soup, kuva muchikwata che splitters. Kutaura zvazviri, vanogona kunzi kuti mabhodhoro mano.

Kana isu nezvazvo Poe-adapters, splitters vari, ivo zvakagadzirirwa kushanda mamwe marudzi mano - Poe-chinja. Ndizvo ravo basa chikuru - kuparadzana samambure Data kupinda vakaparadzana hova kuti unozotevera nhepfenyuro pamusoro mudziyo kuti hamuzi muchikwata che unoparadza mano. Splitters ndivo mhosva voltage kuchinja izvo rinoshandisirwa kwavari, kuna avo siyana vari optimum kuti chinouraya midziyo - semuenzaniso, zvingava zviri nhamba 5, 12 kana 48 V.

Uyewo splitters vari Classified kupinda mhando mbiri - basa uye kungogara. Asi kutanga, vanogona kushanda sechinhu chinja, uye pamwe zvitengeswa adapters. mano kwakadaro zvinosanganisira Somuenzaniso, mahwanda mhando DWL-P50 kubva D-Link. Poe-adhaputa semhosva mudziyo mhando pasi kukurukurwa kunogonawo pusa. Vanogona chete kushanda injectors. Muchiitiko chino, ndivo nyanzvi, vanowanzoororwa kutengeswa pamwe navo rimwe pasuru.

Nuances kushanda adapters

Zvakakodzera kubatana adapters Rino Simba pamusoro Ethernet michina, zvinetso nesangano nemambure kushanda hazvifaniri kuitika. Asi vamwe matambudziko, nokuti dzakananga mitemo inoshandiswa dzakadaro gadziriro vanogona kuitika. Somuenzaniso, Poe-chinja vangasarudza kuti yezviri kunobva mudziyo haisi unoparadza, uye nomumbure anogona kwenguva de-kwakapa ndechokuti gadziriro iri kushanda iri pusa mahwanda. Zvinokosha, akavapindurawo, kuritsiva nemazita chinoshingaira. Kumwezve dambudziko - kubvisa voltage kana ukaedza kubatanidza unoparadza mudziyo kuti chinja. It zvinogona kugadziriswa nekuisa mamwe devaysa - Poe-convert.

An dzinonakidza ndechokuti achirifananidza mari zvavakanga vachida kuita, izvo akarakasha network, aine vashomanana mano unoparadza nani kushandisa pusa Soup, ane guru - basa. Vamwe IT-vanachiremba vanodavira kuti kunyange pashure uwandu kuwana pfungwa kukasapfuura 3 zvidimbu, unogona kushandisa basa adapters.

Optimum waya mhando

Power pamusoro Internet michina rinoratidza zvanzi kubatanidzwa wakarukwa peya. Asi ivo vari, sezvamunoziva, marudzi akasiyana - somuenzaniso, 2 uye 4 nomwe. Ndeupi munhu zvakanakisisa wakanyatsokodzera kuti kugadzwa zvakakodzera mhando samambure? Maererano nenyanzvi, mashoko functionality wegadziriro achaponesa kushandiswa chero mhando waya. Asi kana chiri mutoro pamusoro chinja - semuenzaniso, kana ukashandisa zvose zvinowanikwa zviteshi zvayo, kuti waya pamwe 4 nomwe - yakanaka kuita.
