Ukutshintsha kwePoEsisixhobo esisetyenziswa ngokubanzi kushishino lokhuseleko namhlanje, kuba iswitshi enika amandla kunye nokuhanjiswa kwedatha kwiswitshi ezikude (ezifana neefowuni ze-IP okanye iikhamera), kwaye idlala indima ebaluleke kakhulu.Xa usebenzisa iiswitshi ze-PoE, ezinye iiswitshi ze-PoE ziphawulwa nge-PoE, kwaye ezinye ziphawulwe nge-PoE+.Ke, yintoni umahluko phakathi kokutshintsha kwePoE kunye nePoE +?

1. Yintoni i-PoE switch

Iiswitshi ze-PoE zichazwa ngumgangatho we-IEEE 802.3af kwaye zinokubonelela ukuya kuthi ga kwi-15.4W yamandla e-DC kwizibuko ngalinye.

2. Kutheni usebenzisa iswitshi yePoE

Kule minyaka imbalwa idlulileyo, bekuqhelekile ukuba amashishini abeke iinethiwekhi ezimbini ezahlukeneyo ezineentambo, enye yeyamandla kunye neyedatha.Nangona kunjalo, oku kongeza ubunzima ekugcinweni kwayo.Ukujongana noku, ukuqaliswa kwe-PoE switch.Nangona kunjalo, njengoko iimfuno zamandla zeenkqubo ezintsonkothileyo neziphucukileyo ezifana neenethiwekhi ze-IP, iVoIP, kunye notshintsho lokucupha, iiswitshi zePoE ziye zaba yinxalenye ebalulekileyo yamashishini kunye namaziko edatha.

3. Yintoni iswitshi yePOE+

Ngophuhliso lobuchwepheshe be-PoE, umgangatho omtsha we-IEEE 802.3at uvela, obizwa ngokuba yi-PoE +, kunye nokutshintsha okusekelwe kulo mgangatho kukwabizwa ngokuba yi-PoE + switch.Umahluko omkhulu phakathi kwe-802.3af (PoE) kunye ne-802.3at (i-PoE +) kukuba izixhobo zombane ze-PoE + zibonelela ngamandla ngokuphindwe kabini njengezixhobo ze-PoE, oku kuthetha ukuba iifowuni zeVoIP eziqhelekileyo ezisetyenzisiweyo, ii-WAP kunye neekhamera ze-IP ziya kuqhuba kwii-port ze-PoE +.

4. Kutheni ufuna iiswitshi zePOE+?

Ngokukhula kwemfuno yokutshintsha kwamandla aphezulu e-PoE kumashishini, izixhobo ezifana neefowuni ze-VoIP, iindawo zokufikelela kwi-WLAN, iikhamera zenethiwekhi kunye nezinye izixhobo zidinga utshintsho olutsha olunamandla aphezulu okuxhasa, ngoko ke le mfuno yakhokelela ngokuthe ngqo ekuzalweni kwe-PoE + switch.

5. Izinto ezilungileyo zokutshintsha kwePoE +

a.Amandla aphezulu: Ukutshintsha kwe-PoE + kunokubonelela ukuya kwi-30W yamandla kwi-port, ngelixa i-PoE switching inokubonelela ukuya kwi-15.4W yamandla kwi-port.Amandla amancinci akhoyo kwisixhobo esinikwe amandla kwi-PoE switch yi-12.95W kwi-port, ngelixa ubuncinci bamandla akhoyo kwi-PoE + switch yi-25.5W ngechweba ngalinye.

b.Ukuhambelana okunamandla: i-PoE kunye ne-PoE + itshintshela amanqanaba abiwe ukusuka kwi-0-4 ngokuhambelana namandla angakanani afunekayo, kwaye xa isixhobo sombane siqhagamshelwe kwisixhobo sokubonelela ngombane, sibonelela ngeklasi yayo kwisixhobo sokubonelela ngombane ukuze isixhobo sombane ingabonelela ngesixa esichanekileyo samandla .I-Layer 1, i-Layer 2, kunye ne-Layer 3 izixhobo zifuna ukusetyenziswa kwamandla aphantsi kakhulu, aphantsi, kwaye aphakathi, ngokulandelanayo, ngelixa i-Layer 4 (i-PoE +) iitshintshi zifuna amandla amaninzi kwaye zihambelana kuphela nezixhobo zombane ze-PoE +.

c.Ukunciphisa iindleko ezongezelelweyo: Le PoE + elula isebenzisa i-cabling eqhelekileyo (Cat 5) ukuze isebenze kunye ne-interfaces ye-Ethernet eqhelekileyo, ngoko akukho "cingo olutsha" olufunekayo.Oku kuthetha ukuba iziseko ezingundoqo ezikhoyo zothungelwano lweekhebhuli zinokuxhaswa ngaphandle kwesidingo sokusebenzisa amandla ombane aphezulu ombane we-AC okanye uqhagamshelo lwamandla olwahlukileyo kwiswitshi nganye ehlonyelweyo.

d.Unamandla ngakumbi: I-PoE + isebenzisa kuphela i-CAT5 intambo yenethiwekhi (ene-8 iingcingo zangaphakathi, xa kuthelekiswa neengcingo ze-4 ze-CAT3), ezinciphisa amathuba okuba nokuphazamiseka kunye nokunciphisa ukusetyenziswa kwamandla.Ukongeza, i-PoE + ivumela abalawuli bothungelwano ukuba babonelele ngokusebenza okukhulu, njengokubonelela ngoxilongo olutsha lwamandla okude, ingxelo yobume, kunye nolawulo lonikezelo lwamandla (kubandakanywa ukujikeleza kwamandla okude kweeswitshi ezifakiweyo).

Ukuqukumbela, iiswitshi ze-PoE kunye nokutshintsha kwe-PoE + zinokutshintsha umbane wenethiwekhi ezifana neekhamera zenethiwekhi, ii-APs, kunye neefowuni ze-IP, kwaye zibe nokuguquguquka okuphezulu, ukuzinza okuphezulu, kunye nokungakhuseleki okuphezulu kukuphazamiseka kwe-electromagnetic.
