Kuyesa kwa masinthidwe a TP-Link okhala ndi PoE yayitali. Ndipo pang'ono za kukweza kwa zitsanzo zakale

M'mbuyomu, tidapanga ukadaulo wa Power over Ethernet muma switch athu pongowonjezera mphamvu zopatsirana. Koma pakugwira ntchito kwa mayankho ndi PoE ndi PoE +, zidawonekeratu kuti izi sizinali zokwanira. Makasitomala athu akukumana osati ndi kusowa kwa bajeti yamagetsi, komanso ndi malire amtundu wa Efaneti - njira yotumizira mauthenga a 100 m. kuchita.

Chifukwa chiyani timafunikira ukadaulo wa PoE wautali?

Mtunda wa mita zana ndi wochuluka. Komanso, kwenikweni chingwe sichimayikidwa molunjika: muyenera kuyendayenda kuzungulira nyumbayo, kuwuka kapena kugwa kuchokera ku chingwe chimodzi kupita ku china, ndi zina zotero. Ngakhale m'nyumba zazikuluzikulu, kuchepetsa kutalika kwa gawo la Ethernet kumatha kukhala mutu kwa woyang'anira. 

Tinaganiza zogwiritsa ntchito chitsanzo cha nyumba ya sukulu kuti tisonyeze momveka bwino kuti ndi zipangizo ziti zomwe zidzalandire magetsi pogwiritsa ntchito PoE ndikugwirizanitsa ndi intaneti (nyenyezi zobiriwira), komanso zomwe sizidzatero (nyenyezi zofiira). Ngati zida za netiweki sizingayikidwe pakati pamilanduyo, ndiye kuti pazida zowopsa zida sizitha kulumikizidwa:

Kuti mudutse malire amtunduwu, ukadaulo wa Long Range PoE umagwiritsidwa ntchito: umakupatsani mwayi wokulitsa malo omwe amalumikizidwa ndi netiweki yamawaya ndikulumikiza olembetsa omwe ali pamtunda wamamita 250. Mukamagwiritsa ntchito Long Range PoE, deta ndi magetsi zimasamutsidwa m'njira ziwiri:

1. Ngati mawonekedwe liwiro ndi 10 Mbps (wokhazikika Efaneti), ndiye kufala munthawi yomweyo mphamvu zonse ndi deta n'zotheka pa zigawo mpaka 250 mamita yaitali.
2. Ngati liwiro la mawonekedwe likhazikitsidwa ku 100 Mbps (zamitundu TL-SL1218MP ndi TL-SG1218MPE) kapena 1 Gbps (yachitsanzo TL-SG1218MPE), ndiye kuti palibe kusamutsa kwa data komwe kudzachitika - kutengera mphamvu kokha. Pankhaniyi, njira ina yotumizira deta idzafunika, mwachitsanzo, mzere wofanana wa kuwala. Long Range PoE pankhaniyi ingogwiritsidwa ntchito pamagetsi akutali.

Choncho, pogwiritsira ntchito Long Range PoE pagawo la sukulu yomweyi, zipangizo zamakono zomwe zimathandizira kuthamanga kwa 10 Mbps zimatha kupezeka nthawi iliyonse.

 

Zosintha zomwe zimathandizira Long Range PoE zitha kuchita

Ntchito ya Long Range PoE ikupezeka pama switch awiri pamzere wa TP-Link: Gawo #: TL-SG1218MPE и Chithunzi cha TL-SL1218MP.

TL-SL1218MP ndi chosinthira chosayendetsedwa. Ili ndi madoko 16, bajeti yake yonse ya PoE ndi 192 W, yomwe imalola kuti ipereke mphamvu mpaka 30 W padoko lililonse. Ngati bajeti yamagetsi sinadutse, madoko onse 16 a Fast Ethernet amatha kulandira mphamvu.  

Kukonzekera kumachitika pogwiritsa ntchito masiwichi pagawo lakutsogolo: imodzi imayendetsa mawonekedwe a PoE Yakutali, ndipo yachiwiri imakonza zoyambira pamadoko pogawa bajeti yamagetsi. 

TL-SG1218MPE ndi masiwichi a Easy Smart. Mutha kuyang'anira chipangizochi kudzera pa intaneti kapena zida zapadera. 

Mu gawo la mawonekedwe a System, olamulira ali ndi mwayi wogwiritsa ntchito chizolowezi chokhazikika: kusintha malowedwe ndi mawu achinsinsi kwa akaunti ya woyang'anira, kukhazikitsa adilesi ya IP ya gawo lowongolera, kukonzanso firmware, ndi zina zotero.

Njira zogwirira ntchito pamadoko zimayikidwa mugawo la Kusintha → Port Setting. Pogwiritsa ntchito ma tabo otsala a gawoli, mutha kuloleza / kuletsa IGMP ndikuphatikiza mawonekedwe amthupi m'magulu.

Gawo la Monitoring limapereka chidziwitso chokhudza momwe ma switch port amagwirira ntchito. Muthanso kuyang'anira kuchuluka kwa magalimoto, kuyatsa kapena kuletsa chitetezo cha loop, ndikuyendetsa choyesa chingwe chomangidwa.

Kusintha kwa TL-SG1218MPE kumathandizira mitundu ingapo ya netiweki: 802.1q tagging, VLAN yochokera padoko, ndi MTU VLAN. Mukamagwira ntchito mu MTU VLAN mode, kusinthako kumangolola kusinthana kwa magalimoto pakati pa madoko ogwiritsira ntchito ndi mawonekedwe a uplink, ndiko kuti, kusinthana kwa magalimoto pakati pa madoko a ogwiritsa ntchito ndikoletsedwa mwachindunji. Tekinoloje iyi imatchedwanso Asymmetric VLAN kapena Private VLAN. Amagwiritsidwa ntchito kukonza chitetezo chamaneti kuti akalumikizidwa ndi chosinthira, wowukirayo sangathe kuwongolera zida.

Mu gawo la QoS, mutha kuyika patsogolo mawonekedwe, kukonza malire othamanga, ndikuthana ndi mkuntho.

Mu gawo la PoE Config, woyang'anira atha kuchepetsa mwamphamvu mphamvu yayikulu yomwe ikupezeka kwa wogula wina, kuyika patsogolo mphamvu ya mawonekedwe, kulumikiza kapena kuletsa ogula.

Kuyesa Utali Watali

Pa TL-SL1218MP tathandizira thandizo la Long Range pamadoko asanu ndi atatu oyamba. Foni yathu yoyeserera ya IP idagwira ntchito bwino. Kupyolera mu zoikamo foni, tinapeza kuti anagwirizana liwiro ndi 10 Mbps. Kenako tinasintha kusintha kwa Long Range PoE kukhala Off ndikuyang'ana zomwe zidachitika pafoni yoyeserera pambuyo pake. Chipangizocho chinayambika bwino ndikunena kuti chikugwiritsa ntchito 100 Mbps pa intaneti, koma deta sinatumizidwe kudzera pa tchanelo ndipo foniyo sinalembetsedwe ndi siteshoni. Chifukwa chake, kupatsa mphamvu ogula olumikizidwa panjira zazitali za Efaneti ndizotheka popanda kuyambitsa mawonekedwe a Long Range PoE, koma pakadali pano mphamvu yokhayo idzatumizidwa kudzera panjira, osati data.

Mu mphamvu yokhazikika pamtundu wa Efaneti (pamene kutalika kwa gawo sikudutsa mamita 100), kutumiza mphamvu ndi deta kumachitika mofulumira mpaka 1 Gbps kuphatikizapo. Kuyesa kugwiritsa ntchito foni yoyendetsedwa ndi PoE komanso yolumikizidwa ndi chingwe chautali wautali kunapambana.

Pakusintha kwa TL-SG1218MPE tidasinthira doko kukhala 10 Mbps Half Duplex mode - chipangizocho chidalumikizidwa bwino.

Mwachilengedwe, tinkafuna kudziwa mphamvu zomwe foni imawononga ndi kulumikizana uku, zidapezeka kuti ndi 1,6 W.

Koma ngati musintha mawonekedwe osinthira kukhala 100 Mbps Half Duplex kapena 100 Mbps Full Duplex opareshoni, kulumikizana ndi foni kumatayika nthawi yomweyo ndipo sikubwezeretsedwa.

Mawonekedwe omwewo ali mu Link Down state.

Pafupifupi chinthu chomwecho chimachitika ngati mawonekedwe asinthidwa kukhala liwiro lodziwikiratu ndi njira yolumikizirana yapawiri. Chifukwa chake, njira yokhayo yogwiritsira ntchito zigawo zazitali za Efaneti ndikuyika pamanja liwiro lolumikizira ku 10 Mbps.

Tsoka ilo, zigawo zazitali zoterezi sizizindikirika ndi choyesa chingwe chomangidwa.

Kusintha ma switch ena a PoE

Popeza kuchuluka kwa zida zoyendetsedwa ndi PoE kukuchulukirachulukira, tasintha mphamvu zamagetsi zamamitundu akale. Tsopano, m'malo mwa magetsi a 110 W ndi 192 W, mitundu yonse idzakhala ndi 150 W ndi 250 W mayunitsi. Zosintha zonsezi zitha kuwoneka patebulo:

Pamene teknoloji ya PoE inayamba kulowa mu mlingo wa ogula, kusintha kwina pamzerewu kunali kukhazikitsidwa kwa masinthidwe opangidwira maofesi ang'onoang'ono ndi ntchito zapakhomo.

Mu 2019, mitundu idawoneka pamzere wa masiwichi a Fast Ethernet osayendetsedwa Gawo #: TL-SF1005P и Gawo #: TL-SF1008P kwa 5 ndi 8 madoko. Bajeti yamagetsi yamitunduyi ndi 58 W, ndipo imatha kugawidwa pakati pa magawo anayi (mpaka 15,4 W pa doko). Zosinthazi zilibe mafani; amatha kuyikidwa mwachindunji muofesi ndi malo antchito, zipinda ndikugwiritsidwa ntchito kulumikiza makamera aliwonse a IP ndi mafoni a IP. Masiwichi amatha kuyika patsogolo kugawa kwamagetsi: zikadzaza kwambiri, zida zocheperako zimazimitsidwa.

Zithunzi Gawo #: TL-SG1005P и Gawo #: TL-SG1008P, monga zitsanzo za SF, zimapangidwira kukhazikitsa makompyuta, koma zimakhala ndi gigabit switch, zomwe zimakulolani kuti mugwirizane ndi zipangizo zothamanga kwambiri zomwe zimathandizira 802.3af. 

Sinthani Chithunzi cha TL-SG1008MP Itha kuyikidwa patebulo komanso muchoyikapo. Mtunduwu uli ndi madoko asanu ndi atatu a Gigabit Ethernet, aliwonse omwe amatha kulumikizidwa ndi wogula ndi IEEE 802.3af/pakuthandizira ndi mphamvu yofikira 30 W. Bajeti yonse yamphamvu ya chipangizocho ndi 126 W. Chinthu chapadera cha kusinthako ndi chakuti chimathandizira njira yopulumutsira mphamvu, momwe chosinthira nthawi ndi nthawi chimawombera madoko ake ndikuzimitsa mphamvu ngati palibe chipangizo cholumikizidwa. Izi zimakuthandizani kuti muchepetse kugwiritsa ntchito mphamvu ndi 75%. 

Kuphatikiza pa TL-SG1218PE, mzere wa TP-Link wama switch oyendetsedwa umaphatikizapo mitundu Chithunzi cha TL-SG108PE и Chithunzi cha TL-SG1016PE. Ali ndi bajeti yofanana yamphamvu ya chipangizocho - 55 W. Bajetiyi ikhoza kugawidwa pakati pa madoko anayi omwe ali ndi mphamvu yotulutsa mpaka 15,4 W pa doko lililonse. Zosinthazi zili ndi firmware yofanana ndi TL-SG1218PE, motsatana, ndipo ntchito zake ndi zofanana: kuyang'anira maukonde, kuika patsogolo magalimoto, QoS, MTU VLAN.

Kufotokozera kwathunthu kwamitundu yazida za TP-Link PoE kulipo kugwirizana.
