Kwihlabathi elihlala litshintsha lobuchwepheshe benethiwekhi, ukukhetha iswitshi kubalulekile ekusebenzeni kakuhle kwenethiwekhi kunye nokusebenza kwayo. Phakathi kweentlobo ezininzi zeswitshi, iiswitshi zePower over Ethernet (PoE) zifumene ingqalelo enkulu ngenxa yeempawu zazo ezizodwa. Ukuqonda umahluko phakathi kweeswitshi zePoE kunye neeswitshi ezisemgangathweni kubalulekile kumashishini nakubantu abafuna ukuphucula iziseko zabo zenethiwekhi.
A Utshintsho lwePoE sisixhobo senethiwekhi esingaxhasi nje kuphela ukuhanjiswa kwedatha kodwa sikwabonelela ngamandla kwizixhobo eziqhagamshelweyo ngentambo ye-Ethernet efanayo. Le teknoloji ivumela izixhobo ezifana neekhamera ze-IP, iifowuni ze-VoIP, kunye neendawo zokufikelela ezingenazingcingo ukuba zifumane idatha kunye namandla ngaxeshanye, nto leyo esusa imfuneko yokunikezelwa kombane okwahlukileyo. Iiswitshi ze-PoE ziyafumaneka kwimigangatho eliqela, kubandakanya i-IEEE 802.3af (PoE), i-IEEE 802.3at (PoE+), kunye ne-IEEE 802.3bt (PoE++, nganye inikezela ngamanqanaba ahlukeneyo ombane ukuze ilungele izixhobo ezahlukeneyo.
Kwelinye icala, iiswitshi eziqhelekileyo zizixhobo zenethiwekhi zemveli ezisetyenziselwa ukudlulisa idatha. Aziboneleli ngombane kwizixhobo ezixhunyiweyo, oko kuthetha ukuba nasiphi na isixhobo esifuna umbane kufuneka sifakwe kwiplagi yombane eyahlukileyo. Iiswitshi eziqhelekileyo zihlala zisetyenziswa kwiindawo apho izixhobo sele zisebenza okanye apho umbane ungeyongxaki.
Amandla:Umahluko obalulekileyo phakathi kweswitshi yePoE kunye neswitshi eqhelekileyo kukwazi kwayo ukuhambisa umbane. Iswitshi yePoE inganika amandla izixhobo phezu kwentambo ye-Ethernet, ngelixa iswitshi eqhelekileyo ingenako. Olu phawu lwenza kube lula ukufakela kwaye lunciphisa ukuxinana kweentambo kunye neeadaptha zamandla.
Ukuguquguquka kokufakwa:Iiswitshi zePoE zibonelela ngokuguquguquka okukhulu ekubekweni kwesixhobo. Ngenxa yokuba azidingi ndawo yokukhupha umbane ekufutshane, izixhobo zinokufakwa kwiindawo apho umbane ungafumaneki lula, njengeekhamera ze-IP ezifakwe eluphahleni okanye kwiindawo ezikude zeendawo zokufikelela ezingenazingcingo. Iiswitshi eziqhelekileyo, nangona kunjalo, zifuna ukuba izixhobo zibekwe apho umbane ukhoyo.
Ukusebenza kakuhle kweendleko:Nangona ixabiso lokuqala lee-PoE switches linokuba phezulu kunee-switches eziqhelekileyo, zingonga imali ekuhambeni kwexesha. Ngokunciphisa isidingo seentambo ezongezelelweyo kunye neeplagi, amashishini anokonga kwiindleko zokufakela kunye nokulungisa. Ukongeza, ukukwazi ukunika amandla izixhobo ezininzi nge-switch enye kunciphisa ukusetyenziswa kwamandla.
Ulawulo lwenethiwekhi:Iiswitshi ezininzi zePoE zixhotyiswe ngeempawu zolawulo eziphambili ezivumela ulawulo olungcono kunye nokubeka iliso kwizixhobo ezixhunyiweyo. Oku kuquka ukubeka phambili amandla, ukubeka iliso ekusetyenzisweni kwamandla, kwanokuqalisa kwakhona izixhobo kude. Ezi mpawu zolawulo eziphambili zihlala zingekho kwiiswitshi eziqhelekileyo.
Ukukhula:Iiswitshi zePoE zihlala zinokwandiswa ngakumbi kuneeswitshi eziqhelekileyo. Njengoko ishishini lakho likhula kwaye lifuna izixhobo ezingaphezulu, iiswitshi zePoE zinokuthwala izixhobo ezintsha ngokulula ngaphandle kokufuna umsebenzi omkhulu wombane. Iiswitshi eziqhelekileyo, kwelinye icala, zinokufuna iziseko ezongezelelweyo zokuxhasa izixhobo ezintsha ezisebenza ngamandla.
Ekugqibeleni, ukukhetha phakathi Utshintsho lwePoE kwaye utshintsho oluqhelekileyo luxhomekeke kwiimfuno ezithile zenethiwekhi yakho. Kwiimeko ezifuna izixhobo ezisebenza ngamandla, utshintsho lwePoE lubonelela ngeenzuzo ezibalulekileyo ekunikezelweni kwamandla, ukuguquguquka kokufakwa, ukusebenza kakuhle kweendleko, ulawulo lwenethiwekhi, kunye nokukhula. Ukuqonda olu mahluko kunokunceda amashishini kunye nabantu ngabanye ukuba benze izigqibo ezinolwazi xa beyila kwaye bephucula iziseko zabo zenethiwekhi. Njengoko iteknoloji iqhubeka ihambela phambili, indima yotshintsho lwePoE kwiinethiwekhi zanamhlanje inokuba yinto ebalaseleyo, ibenze babe yimpahla exabisekileyo kuyo nayiphi na intlangano.
