Ukushintsha kuvame ukusetshenziswa kumaphrojekthi amanje abuthakathaka, ikakhulukaziUkushintsha kwe-POE.I-POE ibizwa nangokuthi isistimu yendawo yendawo esekelwe kunethiwekhi (POL, Power over LAN) noma i-Active Ethernet (Active Ethernet), ngezinye izikhathi ebizwa ngokuthi Amandla phezu kwe-Ethernet.Lokhu ukucaciswa okujwayelekile kwakamuva kokudluliswa kwedatha kanye namandla kagesi kusetshenziswa izintambo zokudlulisa ezijwayelekile ze-Ethernet, futhi kugcina ukuhambisana nezinhlelo ezikhona ze-Ethernet nabasebenzisi.Ngakho-ke, sikhetha kanjani ukushintshwa kwe-POE?

1. Cabangela amandla emishini yakho

Ngokuhambisanayo khetha iswishi ye-PoE enamandla amakhulu.Uma amandla okusebenza kwakho engaphansi kuka-15W, bese ukhetha ukushintsha kwe-PoE esekela izinga le-802.3af.Uma amandla amakhulu kuno-15W, khetha iswiwi yamandla aphezulu enezinga elingu-802.3.Njengamanje, amaswishi amaningi e-PoE asekela kokubili i-af ne-at, ngakho-ke qaphela kakhulu lapho uthenga.

2. Ichweba elingokoqobo

Okokuqala, kuyadingeka ukunquma inani le-switch interfaces, inombolo ye-optical fibre port, ukuphathwa kwenethiwekhi, isivinini (10/100/1000M) nezinye izinkinga.Njengamanje, izindawo ezisetshenziswayo emakethe ikakhulukazi ziyi-8, 12, 16, kanye namachweba angama-24.Ngokuvamile kuba nembobo eyodwa noma ezimbili zefiber optical, futhi kufanele unake ukuthi imbobo yokubona ingu-100M noma 1000M.Kuya ngesimo.

Amaswishi e-PoE ngokuvamile asetshenziselwa ukuxhuma amatheminali anamandla futhi asetshenziswa njengamaswishi okufinyelela.Cabangela inombolo yezimbobo zokuphakela amandla e-PoE ezisekelwa iswishi ngokuya ngenani lamadivayisi aphethwe amandla.Ukwengeza, kuyadingeka futhi ukucabangela izinga eliphezulu ichweba elidinga ukulisekela ngokuvumelana netheminali enamandla kanye nezidingo zangempela.Isibonelo, uma ichweba le-AP kuyi-Gigabit futhi isebenzisa i-11AC noma i-dual-band, ukufinyelela kwe-Gigabit kungacatshangwa.

3. Imingcele yokunikezwa kwamandla

Khetha iswishi efanelekile ngokuya ngephrothokholi yokunikezwa kwamandla (efana ne-802.3af, 802.3at noma i-PoE engajwayelekile) esekelwa itheminali enamandla (AP noma ikhamera ye-IP).Iphrothokholi yokunikezwa kwamandla ye-PoE esekelwe iswishi kufanele ihambisane netheminali enikwe amandla.Ziningi izingozi zokuphepha ezingaba khona kumaswishi e-PoE angajwayelekile.Kunconywa ukuthi uzame ukukhetha amadivaysi okushintsha e-48V PoE ajwayelekile.

4. Uhlelo lwezintambo

Abasebenzisi bangaqhathanisa futhi babale izindleko zezintambo zikagesi zasendaweni zetheminali kanye nezindleko zokusebenzisa iswishi ye-PoE ngokuphakelwa kukagesi.Njengamanje, ibanga lokunikezwa kwamandla lokushintshwa kwe-PoE lingaphakathi kwamamitha ayi-100.Ayikho imikhawulo yesakhiwo, engonga cishe u-50% wezindleko zizonke.Izintambo ezingaphakathi kwamamitha angu-100 zinganweba kalula inethiwekhi ngaphandle kokuvinjelwa ukwakheka kwezintambo zikagesi.Lengisa ama-AP angenantambo, amakhamera enethiwekhi nezinye izisetshenziswa zetheminali ezindongeni eziphakeme noma ophahleni ukuze kunwetshwe kalula, izintambo ezilula, nokubukeka okuhle.

5. Ukwesekwa kwangaphambi kokuthengisa kanye nangemuva kokuthengisa

Khetha abathengisi abathembekile ukuze uthole izinsiza ezichwepheshile zokuthengisa ngaphambilini nangemuva kokuthengisa

JHA,umkhiqizi ophezulu e-Shenzhen, osebenza nge-R&D kanye nokukhiqizwa kweUkushintsha kwe-PoE,ukushintsha kwezimboni, isiguquli semidiyanezinye izinto zokuxhumana,wamukelekile ukubonisana
