1. PoE idasanzwe na PoE isanzwe

Kuri PoE isanzwe yubahiriza IEEE 802.3af / kuri / bt kandi ifite protocole y'intoki. PoE itari isanzwe ntabwo ifite protocole yo guhana intoki, kandi itanga 12V, 24V cyangwa 48V DC itanga amashanyarazi.

Imashanyarazi isanzwe ya PoE ifite chip yo kugenzura imbere, ifite imikorere yo gutahura mbere yo gutanga amashanyarazi. Iyo igikoresho gihujwe, amashanyarazi ya PoE azohereza ikimenyetso kumurongo kugirango amenye niba itumanaho murusobe ari igikoresho cya PD gishyigikira amashanyarazi ya PoE. Igicuruzwa kitari gisanzwe cya PoE nigikoresho-gitanga-umuyoboro wogukoresha amashanyarazi, gitanga ingufu mukimara gukoreshwa. Nta ntambwe yo gutahura, kandi itanga imbaraga utitaye ko terminal ari igikoresho gikoreshwa na PoE, kandi biroroshye cyane gutwika igikoresho.

2. Uburyo busanzwe bwo kumenyekanisha ibintu bidasanzwe bya PoE

Nigute dushobora gutandukanya ibintu bidasanzwe bya PoE? Uburyo bukurikira burashobora kugeragezwa.

a. Reba voltage

Ubwa mbere, ucire urubanza hafi ya voltage yo gutanga. IEEE 802.3 af / kuri / bt protocole iteganya ko icyambu cya PoE gisanzwe gisohoka voltage iri hagati ya 44-57V. Umuyagankuba usanzwe utanga amashanyarazi usibye 48V nibicuruzwa bitari bisanzwe, nkibicuruzwa bisanzwe 12V na 24V. Nyamara, amashanyarazi ya 48V ntashobora kuba byanze bikunze kuba ibicuruzwa bisanzwe bya PoE, bityo igikoresho cyo gupima voltage nka multimeter kirakenewe kugirango tumenye.

b. Gupima hamwe na multimeter

Tangira igikoresho, uhindure multimeter kumwanya wo gupima voltage, hanyuma ukore kuri pine itanga amashanyarazi yibikoresho bya PSE hamwe namakaramu abiri ya multimeter (mubisanzwe 1/2, 3/6 cyangwa 4/5, 7/8 bya RJ45 icyambu), niba igikoresho gifite umusaruro uhamye wa 48V cyangwa izindi voltage zifite agaciro (12V, 24V, nibindi) zapimwe, nibicuruzwa bitari bisanzwe. Kuberako muriki gikorwa, PSE itamenya ibikoresho bikoreshwa (hano ni multimeter), kandi ikoresha 48V cyangwa izindi voltage zagaciro mumashanyarazi.

Ibinyuranye, niba voltage idashobora gupimwa kandi urushinge rwa multimeter rusimbuka hagati ya 2 na 18V, ni PoE isanzwe. Kuberako kuri iki cyiciro, PSE iri kugerageza itumanaho rya PD (hano ni multimeter), kandi multimeter ntabwo ari PD yemewe n'amategeko, PSE ntizatanga amashanyarazi, kandi nta voltage ihamye izabyara.

c. Hifashishijwe ibikoresho nka disiketi ya PoE

Mu rwego rwo koroshya kwishyiriraho imishinga n'abakozi bashinzwe kuyobora kugirango bamenye vuba kandi bamenye imirongo y'urusobe rwa PoE, menya niba ikimenyetso cy'urusobe gifite amashanyarazi ya PoE, niba PoE ikora bisanzwe, kandi niba igikoresho ari PoE isanzwe cyangwa ibicuruzwa bisanzwe bya PoE, Utop yakoze ubushakashatsi bwa PoE.

Iki gicuruzwa gishyigikira hagati yo hagati (4/5 7/8) no gutahura amaherezo (1/2 3/6), gishyigikira IEEE802.3 af / kuri PoE isanzwe na PoE idasanzwe; Probe PoE Imigaragarire cyangwa umugozi. Gusa uhuze disiketi ya PoE kumurongo ukora, kandi LED iherereye kuri disiketi ya PoE izamurika cyangwa ihume. Guhumura bisobanura PoE isanzwe, urumuri ruhoraho rusobanura PoE idasanzwe. Igikoresho gito cyo gutahura kirashobora gutanga ibyoroshye mubwubatsi.
