Nrog rau kev txhim kho txuas ntxiv ntawm PoE thev naus laus zis, PoE keyboards tam sim no nyob rau hauv ib qho kev paub tab heev, txawm li cas los xij, vim tias tam sim no kev lag luam saib xyuas nyob rau hauv qhov siab ntawm tus nqi, qhov zoo ntawm cov xaiv PoE keyboards lossis cables tsawg dhau, lossis cov qauv tsim nws tus kheej. yog qhov tsis tsim nyog, uas yuav ua rau muaj kev ua haujlwm hnyav tshwj xeeb rau kev saib xyuas ntawm PoE fais fab mov tej yaam num. Lub network saib xyuas qhov project txawv ntawm qhov sib txuas sib txuas sib txuas sib txuas, cov ntaub ntawv xa tawm ntim siab, lub zog siab, thiab nws yuav tsum tau ua haujlwm tsis cuam tshuam ib puag ncig, yog li qhov pom tias PoE fais fab mov tsis ruaj khov. Tab sis yog POE fais fab mov tiag tiag tsis ruaj khov? Cia peb qhia seb PoE keyboards tuaj yeem txuas nrog ruaj khov thiab qhov zoo ntawm kev ruaj ntseg ntawm PoE keyboards yog dab tsi? Cia peb saib!

Yuav ua li cas kom ruaj ntseg kev twb kev txuas ntawm PoE hloov?

① Siv tus qauv PoE hloov pauv. Tsis yog tus qauv PoE keyboards tsis muaj IEEE802.3af lossis IEEE802.3at raws tu qauv. Txawm hais tias cov khoom siv davhlau ya nyob twg txhawb nqa PoE fais fab mov, yuam 48V tso zis hluav taws xob yuav ua rau lub davhlau ya nyob twg puas. Yog li ntawd, kev siv tus qauv PoE hloov pauv rau kev sib txuas yog thawj kauj ruam los xyuas kom meej tias kev ua haujlwm ruaj khov ntawm lub network.

②Siv cov hlua khi uas tsim nyog. Zam tsis txhob yuav cov hlua khi uas tsis tsim nyog. Vim hais tias lawv tsis tau tsim nyob rau hauv nruj raws li qhov yuav tsum tau ntawm cov qauv network cables, tooj liab-clad steel / txhuas / hlau yuav tshwm sim. Yog li ntawd, qhov kev tiv thaiv ntawm lub network cable yuav loj thiab nws tsis haum rau PoE fais fab mov.

③ Txiav txim siab siv lub zog ntawm cov khoom siv davhlau ya nyob twg. Cov qauv sib txawv PoE hloov pauv muaj qhov sib txawv ntawm cov khoom siv hluav taws xob, xws li: IEEE802.3af tus qauv POE hloov tuaj yeem muab lub zog rau cov khoom siv nrog lub zog siab tshaj plaws tsis pub tshaj 15.4W; Ib qho kev hloov pauv PoE uas ua raws li IEEE802.3at tus qauv tuaj yeem muab lub zog rau cov khoom siv uas nws qhov siab tshaj plaws siv tsis tshaj 30W. Raws li qhov kev ncua deb ntawm kev sib kis thiab cov khoom poob, qhov siab tshaj plaws kev siv hluav taws xob tuaj yeem muab tau qis dua.

④ Qhia meej txog cov khoom siv davhlau ya nyob twg. Raws li tus qauv IEEE802.3af, yog tias tag nrho PoE fais fab mov ntawm 24-chaw nres nkoj PoE hloov mus txog 370W, nws tuaj yeem muab 24 qhov chaw nres nkoj (370/15.4=24),; Tab sis yog tias nws raug xam raws li IEEE802.3at tus qauv rau ib qho chaw nres nkoj siab tshaj plaws ntawm 30W, tib lub sijhawm, nws tsuas yog muab lub zog rau 12 qhov chaw nres nkoj feem ntau (370/30 = 12).

⑤ Txiav txim qhov kis tau tus mob. Lub hwj chim mov nrug ntawm PoE hloov yog txiav txim siab los ntawm kev sib kis ntawm cov ntaub ntawv teeb liab. Thaum tus nqi kis tau tus mob yog 100Mbps, qhov siab tshaj plaws nyob deb uas cov ntaub ntawv teeb liab kis tau yog 100m. Yog li, kev txiav txim siab qhov sib kis tau raws li qhov sib kis tus nqi yog ib qho ntawm cov yam ntxwv uas ua kom muaj kev sib txuas ruaj khov ntawm PoE hloov.

⑥ Muaj IETF RFC2544 tus qauv. Cov qauv no tuaj yeem muab cov kev pabcuam cuam tshuam rau kev ntsuas kev ntsuas los ntsuas qhov kev sib txuas ntawm cov khoom siv sib txuas hauv lub network, tus lej rov qab-rau-rov qab thav ntawv, pob ntawv poob tus nqi thiab kev ua haujlwm qeeb, thiab saib xyuas kev sib txuas ruaj khov ntawm PoE keyboards.
