Pakutanga, isu takagadzira Power pamusoro peEthernet tekinoroji muma switch edu chete munzira yekuwedzera simba rinofambiswa. Asi panguva yekushanda kwemhinduro nePoE nePoE +, zvakava pachena kuti izvi zvakanga zvisina kukwana. Vatengi vedu vanotarisana kwete chete nekushaikwa kwesimba rebhajeti, asiwo neyakajairwa muganhu weEthernet network - ruzivo rwekufambisa ruzivo rwemamita zana. tsika.
Nei tichida tekinoroji yePoE refu?
Chinhambwe chemamita zana chakawandisa. Uyezve, muchokwadi tambo haina kumboiswa mumutsara wakatwasuka: unofanirwa kutenderera kumativi ese echivako, kusimuka kana kudonha kubva kune imwe tambo chiteshi kuenda kune imwe, zvichingodaro. Kunyangwe muzvivakwa zvepakati nepakati, iyo inogumira pakureba kwechikamu cheEthernet inogona kushanduka kuita musoro wemusoro kune maneja.
Takasarudza kushandisa muenzaniso wechivako chechikoro kuratidza zvakajeka kuti ndezvipi zvigadziri zvichakwanisa kugamuchira magetsi uchishandisa PoE uye kubatanidza kune network (nyeredzi dzakasvibirira), uye izvo zvisingazoiti (nyeredzi tsvuku). Kana michina yetiweki isingagone kuisirwa pakati pemakesi, saka panguva dzakanyanyisa maturusi haakwanise kubatana:
Kuti upfuure muganho wepakati, Long Range PoE tekinoroji inoshandiswa: inokutendera kuti uwedzere nzvimbo yekuvhara yewaya network uye ubatanidze vanyoreri vari chinhambwe chinosvika 250 metres. Kana uchishandisa Long Range PoE, data nemagetsi zvinofambiswa nenzira mbiri:
- Kana iyo interface yekumhanyisa iri 10 Mbps (yakajairika Ethernet), ipapo kutapurirana kwesimba uye data panguva imwe chete kunogoneka pazvikamu zvinosvika 250 metres kureba.
- Kana iyo interface yekumhanyisa yakasetwa ku100 Mbps (yemhando TL-SL1218MP uye TL-SG1218MPE) kana 1 Gbps (yemuenzaniso TL-SG1218MPE), saka hapana kuchinjisa data kuchaitika - chete kufambisa kwesimba. Muchiitiko ichi, imwe nzira yekufambisa data ichadiwa, semuenzaniso, mutsara wakafanana. Yakareba Range PoE mune iyi kesi inongoshandiswa kune kure kure simba.
Saka, kana uchishandisa Long Range PoE panharaunda yechikoro chimwe chete, network network inotsigira kumhanya kwe10 Mbps inogona kuwanikwa chero nguva.
Ndeapi ma switch anotsigira Long Range PoE anogona kuita
Iyo Long Range PoE basa rinowanikwa pane maviri switch mumutsara weTP-Link: ΠΈ .
TL-SL1218MP ishanduko isina kutariswa. Ine zviteshi gumi nematanhatu, bhajeti rayo rose rePoE i16 W, iyo inoibvumira kupa simba rinosvika 192 W pachiteshi. Kana bhajeti remagetsi rikasapfuurwa, ese gumi nematanhatu Fast Ethernet ports anogona kugamuchira simba.
Kugadzirisa kunoitwa pachishandiswa switch pane yekumberi: imwe inomutsa iyo Yakareba Range PoE modhi, uye yechipiri inogadzirisa kukosha kwezviteshi kana ichigovera bhajeti resimba rekuchinja.
TL-SG1218MPE ndeye Easy Smart switch. Iwe unogona kubata chishandiso kuburikidza newebhu interface kana hunyanzvi zvinoshandiswa.
Muchikamu cheSystem interface, vatariri vanogona kuwana maitiro echinyakare: kushandura login uye password yeadhijitari account, kuseta IP kero ye control module, kugadzirisa firmware, zvichingodaro.
Port inoshanda modes yakaiswa muKuchinja β Port Setting chikamu. Uchishandisa ma tabo asara echikamu, unogona kugonesa / kudzima IGMP uye kusanganisa maratidziro emuviri mumapoka.
Chikamu cheMonitoring chinopa ruzivo rwehuwandu nezvekushanda kweiyo switch ports. Iwe unogona zvakare kutarisisa traffic, kugonesa kana kudzima loop kudzivirira, uye kumhanya yakavakirwa-mukati tambo tester.
Iyo TL-SG1218MPE switch inotsigira akati wandei echokwadi network modes: 802.1q tagging, port-based VLAN, uye MTU VLAN. Paunenge uchishanda muMTU VLAN modhi, shanduko inongobvumira kuchinjika kwetraffic pakati pevashandisi ports uye uplink interface, ndiko kuti, kuchinjanisa traffic pakati pevashandisi zviteshi kunorambidzwa zvakananga. Iyi tekinoroji inonzi zvakare Asymmetric VLAN kana Private VLAN. Inoshandiswa kuvandudza kuchengetedzwa kwetiweki kuitira kuti kana yakabatana nekuchinja, munhu anorwisa haakwanise kubata kutonga kwemidziyo.
Muchikamu cheQoS, unogona kuseta chinongedzo chekutanga, gadzirisa mushandisi traffic kumhanya miganho, uye kubata nemadutu.
Muchikamu chePoE Config, maneja anogona kudzikamisa nechisimba simba guru rinowanikwa kune mumwe mutengi, kuseta simba rekutanga reiyo interface, kubatanidza kana kubvisa mutengi.
Kuedza Long Range
PaTL-SL1218MP isu takagonesa Rutsigiro Rwokureba kumachiteshi masere ekutanga. Yedu yekuyedza IP foni yakashanda zvinobudirira. Kuburikidza nemasetirwo efoni, takaona kuti kumhanya kwakabvumiranwa ndeye 10 Mbps. Takazobatidza Long Range PoE switch to Off totarisa kuti chii chakaitika ku test phone after that. Chishandiso chakabhowa zvakabudirira uye chakashuma chichishandisa iyo 100 Mbps modhi pane network interface, asi data haina kufambiswa kuburikidza nechiteshi uye foni haina kunyoreswa nechiteshi. Saka, kupa simba vatengi vakabatana pamusoro pematanho eEthernet akareba zvinogoneka pasina kumisa iyo Long Range PoE modhi, asi mune iyi nyaya chete simba rinozoendeswa kuburikidza nechiteshi, kwete data.
Musimba rakajairwa pamusoro peEthernet modhi (apo kureba kwechikamu hakupfuuri 100 metres), simba uye kuendesa data kunoitika nekumhanya kusvika ku1 Gbps inosanganisirwa. Kuedza kushanda kwenhare inofambiswa nePoE uye yakabatana netambo yehurefu hwakanyanya kwakabudirira.
Pane TL-SG1218MPE switch takachinja chiteshi kuenda ku10 Mbps Half Duplex mode - mudziyo wakabatana zvakabudirira.
Sezvingatarisirwa, isu taida kuziva kuti isimba rakadii rinoshandiswa nefoni nekubatanidza uku, zvakazoitika kuti yaingova 1,6 W.

Nehurombo, zvidimbu zvetambo refu zvakadaro hazvionekwe neakavakirwa-mukati tambo tester.
Kugadziridza dzimwe PoE switch
Sezvo huwandu hwemidziyo inofambiswa nePoE iri kuramba ichiwedzera, takagadziridza magetsi emhando dzekare. Ikozvino, pachinzvimbo chemagetsi e110 W uye 192 W, ese mamodheru achange aine 150 W uye 250 W mayunitsi. Shanduko idzi dzese dzinogona kuoneka mutafura:
Sezvo tekinoroji yePoE yakatanga kupinda muchikamu chevatengi, imwe shanduko mumutsara yaive kuiswa kwekuchinja kwakagadzirirwa mahofisi madiki uye kushandiswa kwemba.
Muna 2019, mamodheru akaoneka mumutsara weasina kubatwa Fast Ethernet switch ΠΈ ye5 uye 8 zviteshi. Iyo bhajeti yesimba yemamodheru ndeye 58 W, uye inogona kugoverwa pakati pematanho mana (kusvika 15,4 W pachiteshi). Iwo ma switch haana mafeni; anogona kuiswa zvakananga muhofisi nenzvimbo dzebasa, dzimba uye anoshandiswa kubatanidza chero IP kamera uye IP mafoni. Shanduko dzinogona kukoshesa kugovera kwemagetsi: kana kuwandisa kukaitika, zvishandiso zvakaderera-zvinodzimwa.
Models ΠΈ , semhando dzeSF, dzakagadzirirwa kuiswa kwedesktop, asi dzine gigabit switch yakavakirwa, iyo inokutendera kuti ubatanidze yakakwirira-kumhanya terminal michina inotsigira 802.3af.
Chinja Inogona kuiswa zvose patafura uye mune rack. Iyi modhi ine sere Gigabit Ethernet ports, imwe neimwe inogona kubatana kune mutengi neIEEE 802.3af/parutsigiro uye simba rinosvika makumi matatu W. Iyo yakazara simba bhajeti yechishandiso ndeye 30 W. Chinhu chakakosha chekuchinja ndechekuti inotsigira nzira yekuchengetedza simba, iyo inoshandura nguva nenguva ichinongedza zviteshi zvayo uye ichidzima simba kana pasina mudziyo wakabatana. Izvi zvinokubvumira kuderedza kushandiswa kwesimba ne126%.
Kuwedzera kune iyo TL-SG1218PE, iyo TP-Link mutsara weinogadziriswa switch inosanganisira mhando ΠΈ . Ivo vane yakafanana yakazara simba bhajeti remudziyo - 55 W. Iri bhajeti rinogona kugoverwa pakati pezviteshi zvina zvine simba rekubuda rinosvika 15,4 W pachiteshi. Aya ma switch ane firmware yakafanana neTL-SG1218PE, zvichiteerana, uye mabasa akafanana: network monitoring, traffic priorisation, QoS, MTU VLAN.
Tsanangudzo izere yeTP-Link PoE mudziyo renji inowanikwa pa .
