Qhov sib txawv ntawm PoE switches thiab cov switches ib txwm muaj

Hauv lub ntiaj teb thev naus laus zis network uas hloov zuj zus tas li, kev xaiv lub switch yog qhov tseem ceeb rau kev ua haujlwm zoo thiab kev ua haujlwm ntawm network. Ntawm ntau hom switches, Power over Ethernet (PoE) switches tau txais kev saib xyuas ntau vim lawv cov yam ntxwv tshwj xeeb. Kev nkag siab txog qhov sib txawv ntawm PoE switches thiab cov switches txheem yog qhov tseem ceeb rau cov lag luam thiab cov tib neeg uas tab tom nrhiav kev txhim kho lawv cov khoom siv network.

A PoE hloov yog ib lub cuab yeej network uas tsis yog tsuas yog txhawb nqa kev xa cov ntaub ntawv xwb tab sis kuj muab lub zog rau cov khoom siv txuas nrog tib lub Ethernet cable. Cov thev naus laus zis no tso cai rau cov khoom siv xws li IP koob yees duab, VoIP xov tooj, thiab cov chaw nkag wireless kom tau txais ob qho tib si cov ntaub ntawv thiab lub zog tib lub sijhawm, tshem tawm qhov xav tau lub zog sib cais. PoE switches muaj nyob rau hauv ntau tus qauv, suav nrog IEEE 802.3af (PoE), IEEE 802.3at (PoE +), thiab IEEE 802.3bt (PoE ++), txhua tus muab cov qib zog sib txawv kom haum rau ntau yam khoom siv.

Cov keyboards txheem, ntawm qhov tod tes, yog cov khoom siv network ib txwm siv rau kev xa cov ntaub ntawv. Lawv tsis muab hluav taws xob rau cov khoom siv txuas nrog, txhais tau tias txhua yam khoom siv uas xav tau hluav taws xob yuav tsum tau ntsaws rau hauv lub qhov hluav taws xob sib cais. Cov keyboards txheem feem ntau yog siv rau hauv cov chaw uas cov khoom siv twb muaj hluav taws xob lawm lossis qhov twg hluav taws xob tsis yog qhov txhawj xeeb.

Lub zog:Qhov txawv tseem ceeb tshaj plaws ntawm PoE switch thiab lub switch ib txwm yog nws lub peev xwm xa hluav taws xob. Lub PoE switch tuaj yeem xa hluav taws xob rau cov khoom siv hla Ethernet cable, thaum lub switch ib txwm tsis tuaj yeem ua tau. Qhov feature no ua rau kev teeb tsa yooj yim dua thiab txo qhov sib sau ua ke ntawm cov cables thiab cov adapters fais fab.

Kev yooj yim ntawm kev teeb tsa:Cov hloov PoE muab kev ywj pheej ntau dua hauv kev tso cov khoom siv. Vim tias lawv tsis xav tau lub qhov hluav taws xob nyob ze, cov khoom siv tuaj yeem ntsia tau rau hauv qhov chaw uas tsis muaj hluav taws xob yooj yim, xws li lub koob yees duab IP ntsia rau ntawm qab nthab lossis qhov chaw nyob deb rau cov chaw nkag mus rau wireless. Txawm li cas los xij, cov hloov pauv ib txwm xav tau cov khoom siv yuav tsum tau tso rau qhov chaw uas muaj hluav taws xob.

Kev siv nyiaj tsim nyog:Txawm hais tias tus nqi pib ntawm PoE switches yuav siab dua li cov switches ib txwm muaj, lawv tuaj yeem txuag tau nyiaj hauv lub sijhawm ntev. Los ntawm kev txo qhov xav tau ntxiv cov xov hlau thiab qhov hluav taws xob, cov lag luam tuaj yeem txuag tau cov nqi teeb tsa thiab kev saib xyuas. Tsis tas li ntawd, lub peev xwm los muab hluav taws xob rau ntau lub cuab yeej los ntawm ib qho switch txo qhov kev siv hluav taws xob.

Kev tswj hwm network:Ntau lub PoE switches muaj cov yam ntxwv tswj hwm siab heev uas tso cai rau kev tswj hwm zoo dua thiab saib xyuas cov khoom siv txuas nrog. Qhov no suav nrog kev txiav txim siab qhov tseem ceeb ntawm lub zog, saib xyuas kev siv hluav taws xob, thiab txawm tias rov pib dua cov khoom siv. Cov yam ntxwv tswj hwm siab heev no feem ntau tsis muaj nyob rau hauv cov keyboards txheem.

Kev nthuav dav:Cov hloov PoE feem ntau muaj peev xwm nthuav dav dua li cov hloov txheem. Thaum koj lub lag luam loj hlob thiab xav tau ntau yam khoom siv, cov hloov PoE tuaj yeem yooj yim rau cov khoom siv tshiab yam tsis tas yuav tsum tau ua haujlwm hluav taws xob ntau. Cov hloov txheem, ntawm qhov tod tes, tej zaum yuav xav tau cov khoom siv ntxiv los txhawb cov khoom siv hluav taws xob tshiab.

Thaum kawg, xaiv ntawm ib qho PoE hloov thiab tus qauv hloov pauv nyob ntawm qhov xav tau tshwj xeeb ntawm koj lub network. Rau cov chaw uas xav tau cov khoom siv fais fab, PoE switches muaj cov txiaj ntsig zoo hauv kev xa hluav taws xob, kev yooj yim teeb tsa, kev siv nyiaj tsim nyog, kev tswj hwm network, thiab kev nthuav dav. Kev nkag siab txog cov kev sib txawv no tuaj yeem pab cov lag luam thiab cov tib neeg txiav txim siab paub thaum tsim thiab txhim kho lawv cov khoom siv network. Raws li thev naus laus zis txuas ntxiv mus, lub luag haujlwm ntawm PoE switches hauv cov network niaj hnub no yuav dhau los ua qhov tseem ceeb dua, ua rau lawv yog cov khoom muaj nqis rau txhua lub koom haum.
