Guhindura PoEni igikoresho gikoreshwa cyane mubikorwa byumutekano muri iki gihe, kubera ko ari switch itanga imbaraga nogukwirakwiza amakuru kuri sisitemu ya kure (nka terefone ya IP cyangwa kamera), kandi ikagira uruhare runini.Iyo ukoresheje PoE ihindura, bamwe bahindura PoE barangwa na PoE, nabandi bagaragazwa na PoE +.None, ni irihe tandukaniro riri hagati ya PoE ihinduka na PoE +?

1. Guhindura PoE ni iki

Guhindura PoE bisobanurwa na IEEE 802.3af bisanzwe kandi birashobora gutanga amashanyarazi agera kuri 15.4W ya DC kuri buri cyambu.

2. Kuki ukoresha icyerekezo cya PoE

Mu myaka mike ishize ishize, wasangaga ubucuruzi bushyira imiyoboro ibiri itandukanye, imwe kububasha nindi yamakuru.Ariko, ibi byongeyeho ibintu bigoye kubungabunga.Kugirango ukemure iki, intangiriro ya PoE ihinduka.Nyamara, nkuko imbaraga zisabwa na sisitemu igoye kandi igezweho nka neti ya IP, VoIP, hamwe noguhindura igenzura, guhinduranya PoE byahindutse igice cyingenzi cyibigo nibigo byamakuru.

3. Guhindura POE + ni iki

Hamwe niterambere ryikoranabuhanga rya PoE, hagaragara igipimo gishya cya IEEE 802.3at, cyitwa PoE +, kandi abahindura bashingiye kuri iki gipimo nabo bita PoE + switch.Itandukaniro nyamukuru riri hagati ya 802.3af (PoE) na 802.3at (PoE +) ni uko ibikoresho bya PoE + bitanga amashanyarazi bikubye hafi inshuro ebyiri ibikoresho bya PoE, bivuze ko bisanzwe bikoreshwa na terefone VoIP, WAPs na kamera za IP bizakorera ku byambu bya PoE +.

4. Kuki ukeneye guhinduranya POE +?

Hamwe nogukenera imbaraga nyinshi zo guhinduranya PoE mubigo, ibikoresho nka terefone ya VoIP, aho WLAN igera, kamera za neti nibindi bikoresho bikenera amashanyarazi mashya afite imbaraga nyinshi zo gushyigikira, bityo iki cyifuzo cyatumye havuka PoE +.

5. Ibyiza bya PoE +

a.Imbaraga zisumba izindi: Guhindura PoE + birashobora gutanga amashanyarazi agera kuri 30W kuri buri cyambu, mugihe PoE ishobora gutanga amashanyarazi agera kuri 15.4W kuri buri cyambu.Imbaraga ntarengwa ziboneka ku gikoresho gikoreshwa na PoE ihinduka ni 12.95W kuri buri cyambu, mugihe ingufu ntarengwa ziboneka kuri PoE + ni 25.5W kuri buri cyambu.

b.Guhuza gukomeye: PoE na PoE + bahindura bagenera urwego kuva 0-4 ukurikije ingufu zikenewe, kandi mugihe igikoresho cyo gutanga amashanyarazi gihujwe nigikoresho gitanga amashanyarazi, gitanga icyiciro cyacyo kubikoresho bitanga amashanyarazi kugirango ibikoresho bitanga amashanyarazi irashobora kuyiha imbaraga zikwiye.Ibikoresho bya Layeri 1, Igice cya 2, na Layeri 3 bisaba gukoresha ingufu nke cyane, nkeya, kandi ziciriritse, mugihe, icyerekezo cya Layeri 4 (PoE +) gisaba imbaraga nyinshi kandi gihuza gusa nibikoresho bya PoE +.

c.Ibindi bigabanya ibiciro: Iyi PoE + yoroshye ikoresha cabling isanzwe (Cat 5) kugirango ikore hamwe na interineti isanzwe ya Ethernet, bityo rero nta "wire nshya" isabwa.Ibi bivuze ko ibikorwa remezo bya kabili bihari bishobora gukoreshwa bitabaye ngombwa gukoresha amashanyarazi menshi ya AC cyangwa guhuza amashanyarazi kuri buri cyuma cyinjijwe.

d.Ikomeye cyane: PoE + ikoresha umugozi wa CAT5 gusa (ifite insinga 8 zimbere, ugereranije ninsinga 4 za CAT3), bigabanya amahirwe yo gutambuka no kugabanya gukoresha amashanyarazi.Mubyongeyeho, PoE + yemerera abayobozi b'urusobe gutanga imikorere iruta iyindi, nko gutanga amashanyarazi mashya ya kure, gusuzuma imiterere, hamwe no gucunga amashanyarazi (harimo amashanyarazi ya kure ya cycling yashizwemo).

Mu gusoza, abahindura PoE na PoE + bahindura barashobora guhinduranya amashanyarazi nka kamera y'urusobekerane, APs, na terefone ya IP, kandi bifite ihindagurika ryinshi, itekanye cyane, hamwe nubudahangarwa bukabije bwo kwivanga kwa electronique.
