2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:30
Kuv tsis paub meej vim li cas POE tsis suav nrog Hak5 tus Pob Pob Tshiab. (Kho: Kuv paub tseeb tias vim li cas tam sim no, tsuas muaj ntau txoj hauv kev xaiv thiab teeb tsa sib txawv los daws nrog ua ib yam khoom uas tuaj yeem npog lawv txhua tus. Hak5 ua nws zoo kawg nkaus. qhov kev xaiv zoo tshaj yuav yog POE kais sab nraud uas muaj USB chaw tso cai rau koj kom nws sib txuas zoo li qub, qee yam zoo li qhov no. Cov mod no ua haujlwm tab sis nws yog qhov xwm txheej heev, sooooo nws tsis ua haujlwm hauv txhua qhov xwm txheej. Txhua qhov xwm txheej yuav xav tau kev sib txawv me ntsis ntawm kev hloov pauv no.)
FAQ hais tias nws tau raug tshem tawm vim tsis muaj chaw seem hauv kev mob siab ua kom muaj hneev taw me me. Tom qab ua tib zoo saib ua ntej kuv tsis nkag siab vim li cas lawv thiaj los xaus qhov ntawd. Muaj ntau chav nyob nruab nrab ntawm ob lub rooj sib tham, nruab nrab ntawm qhov dhau los ntawm cov hlau lead ua haujlwm nyob rau hauv qab pawg thawj coj saib thiab ib qho zoo nkauj ntawm vaj tsev ntawm RJ45 txuas. Tej zaum nws yog ntau lub sijhawm thiab lossis teeb meem tus nqi, tej zaum nws yuav suav nrog hauv kev rov ua dua tom ntej, Pob Ntawv Ray. (Tau nws, vim yog hluav taws xob hluav taws xob, tsis yog eel nws yog hluav taws xob google nws.) Nws kuj tseem yuav tsis dhau POE ntawm nws ob lub RJ45 txuas vim tias cov khoom seem (4/5 & 7/8) tsis txuas nrog txhua, lawv tau sab laug ntawm ob qho txuas. Qhov ntawd txhais tau tias yog koj ntxig qhov no ua ntej POE ntaus ntawv lub cuab yeej yuav tsis tau txais lub zog los ntawm qhov chaw ntxiv lawm. Kuv tsis xav txog qhov me me li tab sis cia peb mus tom ntej thiab ua kom zoo dua vim tias!
Hauv cov vis dis aus saum toj no koj pom qhov ua tiav POE hloov kho. Txhawm rau sim POE qhov chaw Kuv tab tom thov 48 volts ntawm khub 4/5 & 7/8 (xiav & xim av) rau ib qho ethernet cable uas tsis muaj kev cuam tshuam ntawm ib kawg. Qhov kev txiav tawm kawg yog ntsaws rau hauv Pob Pob Squirrel (ib qho chaw nres nkoj) uas txhawb nws. Ntawm qhov txuas RJ45 uas nyob ib sab kuv txuas lub qub wireless nkag mus nrog lub ethernet jumper luv uas ua rau lub zog nkag mus. BOOM, hluav taws xob ceev rau tes hauj lwm!
Txhawm rau ua kom tiav qhov kev hloov kho/hloov kho no koj yuav tsum xub txuas cov khoom sib txuas (4/5 xiav & 7/8 xim av) nruab nrab ntawm RJ45 txuas mus kom Pob Zeb Pob Zeb yuav hla POE. Tom qab ntawd koj yuav tsum coj mus rhaub rau 48 volts los ntawm ob khub thiab pub nws mus rau qhov ntsuas hluav taws xob lossis DC-DC hloov pauv. Raws li cov ntaub ntawv no kos 120mA ntawm 5V los ntawm micro-b USB chaw nres nkoj, uas zoo li tsis raug. Hauv cov duab saum toj no koj yuav pom cov nthwv dej tam sim no thaum pib. Thaum lub sijhawm khau raj, uas siv sijhawm kwv yees li 35 vib nas this, nws thim 170-230mA. Thaum lub sijhawm ua haujlwm ib txwm muaj, nws kos nruab nrab ntawm 148-150mA, uas yog 30mA dhau qhov ntsuas tshwj xeeb. Siv tus tswj hwm txoj kab los tso 48 volts mus rau 5 volts tsis yog lub tswv yim zoo yog li peb tab tom yuav siv DC rau DC step-down converter ntawm hom "buck". Peb yuav siv tus qauv raws li MP1584 cov hloov pauv qis. Txawm hais tias nws tsuas yog ntsuas rau qhov siab tshaj plaws ntawm 28 volts, nws muaj qhov tso tawm siab tam sim no ntsuas thiab ua haujlwm tau zoo nrog lub teeb thauj khoom. Kuv xav tias nws yuav ua haujlwm zoo xwb. Muaj lwm txoj hauv kev tab sis qhov no yog qhov kuv muaj ntawm tes. (Hloov kho: tom qab lub sijhawm ua haujlwm ntev qhov no tseem ua haujlwm thiab tsim yuav luag tsis muaj cua sov.)
Kauj Ruam 1: Nkag Siab POE
POE tuaj yeem ua rau tsis meej pem thaum xub thawj thiab nrog rau txhua tus qauv, muaj ntau qhov rov ua dua thiab ua ke uas tsis pab tau txhua. Tab sis peb tsis tas yuav txhawj txog peb tus kheej nrog ntau lub ntsiab lus vim tias peb tsis tig lub Pob Pob Zeb rau hauv POE cov cuab yeej siv tau zoo. Peb tsuas yog tapping tawm ntawm kab, tsim tsuas yog me ntsis ntawm cov kab mob cab. Tsis muaj leej twg yuav plam cov txiv ntoo no, vam tias!
Cov ntsiab lus siv:
PSE - Cov Khoom Siv Hluav Taws Xob
Cov cuab yeej siv khoom siv fais fab (PSE) xws li lub tshuab nqus dej, lub hauv paus, qhov hloov pauv, thiab cov routers muab lub zog rau cov cuab yeej siv tau.
PD - Ntaus Ntaus
Cov cuab yeej siv zog (PD) hais txog cov cuab yeej siv network xws li IP lub koob yees duab, WAPs, lossis VoIP xov tooj uas vam khom cov khoom siv fais fab los ua haujlwm.
Txij li Pob Pob Squirrel twb tau tawg txoj hauv kev ntawm cov khoom seem (4/5 & 7/8) lub ntsiab lus nws ua txhaum 1000Base-T cov cim qhia peb yuav mus rau pob tshab pob tshab hom B zog nruab nrab ntawm RJ45 jacks thiab tua tawm txog 0.825W los ntawm nws (5V x 0.150A = 0.75W + 90% hloov dua siab tshiab = 0.825W). Yog li cov pob ntawv pob yuav tsis yog ib txwm PD, rau Hom B PSE, nws tsuas yog ib feem ntawm ethernet cable nrog me ntsis ntawm kev kis kab mob. Nco tseg: Qhov no tsuas yog ua haujlwm tom qab lub midspan POE injector uas yuav rhuav txoj hauv kev ntawm khub 4/5 & 7/8 ntawm qhov hloov pauv thiab cov cuab yeej siv network. Yog tias koj siv txoj hauv kev no thiab txuas ncaj qha mus rau qhov hloov pauv nws yuav tsis sib tham txog kev sib txuas kom raug vim yog cov khoom luv luv.
Yog tias koj xav tau koj Cov Pob Tsiaj Pob los ua haujlwm ntawm Hom A PSE ces es tsis yog siv rau hauv cov khoom seem ntawm RJ45 jacks koj yuav xav tau txuas 48 volt jumpers pub DC-DC hloov pauv mus rau qhov chaw nres nkoj (tus pin 2 & 7) ntawm LAN sab B1601S Base-T Magnetics Module (saib cov ntaub ntawv txuas nrog) rau khub 1/2 & 3/6. Yog tias koj xav tau kom dhau Hom A lub zog los ntawm Pob Tsiaj Pob koj yuav tsum muaj peev xwm txuas tus pin 2 ntawm txhua B1601S thiab tus pin 7 ntawm txhua B1601S ua ke tab sis kuv tsis tau sim qhov no.
Jumpering cov khoom sib txuas nruab nrab ntawm RJ45 txuas yuav txhim kho 1000Base-T teeb liab tab sis ua li ntawd yuav hla Pob Pob Squirrel lub peev xwm los ua nws txoj haujlwm vim nws tsuas tuaj yeem sib tham 10/100Base-T ntawm khub 1/2 & 3/6, yog li ntawd yuav yog tsis muaj qab hau.
Nco ntsoov tias PDs tuaj yeem raug faib ua chav kawm ntawm qhov hloov pauv raws li lawv lub zog xav tau. Hauv kev cia siab, koj Cov Pob Pob Cov Kab yuav pom tau tias yog qhov hluav taws xob me me poob hauv CAT cabling tab sis yog tias qhov chaw nres nkoj koj nyob ze rau qhov siab tshaj plaws rau nws qib kawm nws tuaj yeem ua rau muaj qhov yuam kev dhau/tswb.
Hoob 0:.44 txog 12.96 Watts
Hoob 1:.44 txog 3.84 Watts
Hoob 2: 3.84 txog 6.49 Watts
Hoob 3 6.49 txog 12.95 Watts
Yog tias koj xav kom tau txais kev zoo nkauj lossis koj tsuas xav tau* koj Cov Pob Zeb Nyuaj los ua POE ua raws PD koj tuaj yeem ntxiv POE tus tswj hwm ua ntej ntawm DC-DC hloov pauv xws li qhov no los ntawm Semiconductor, lossis ib qho twg haum rau koj xav tau.

* Kuv tsis xav kom Pob Pob Squirrel ua raws POE PD. Nws twb yog tus neeg siv zais-hauv-tus-nruab nrab. Vim li cas kuv thiaj xav kom nws hais tias, "Hav Mr. Network Hloov, kuv puas tuaj yeem tau txais qee qhov txiv ntoo thov?" Tsis yog, Kuv xav kom nws ua me me kab mob cab me me tsuas yog siv lub zog txaus kom tau los ntawm thaum tsis cuam tshuam nrog kev ua haujlwm ib txwm muaj ntawm PD nyob ntawm lub hom phiaj.
Kauj Ruam 2: Sau Cov Khoom
LUS CEEB TOOM: Txoj haujlwm no yog qib - Kuv tsis muab $%@# yog tias kuv tsoo kuv tus nas me me. Ua ntawm koj tus kheej txoj kev pheej hmoo!

*Nco ntsoov muaj lwm txoj hauv kev xaiv thaum xaiv DC-DC hloov pauv qis, uas yog cov uas tau ntsuas rau 48 volts xws li qhov no mEZD74800A-X tab sis lawv raug nqi ntau dua thiab nyuaj rau nrhiav.
Kauj Ruam 3: Qhuav Txiv Ntoo
Thawj yam ua ntej peb yuav tsum tshem qhov teeb meem ntawd. Luckily Hak5 tau ua siab zoo tsis txhob lo rau rooj plaub lossis siv lwm txoj hauv kev ua kom khaus nws. Nws tsuas yog tuav ua ke sab hauv nrog 3 tabs thiab 4 "sort of" tab tom ntej ntawm micro-b USB chaw nres nkoj fais fab thiaj li yog qhov uas peb yuav pib vim nws yog qhov tsis muaj zog tshaj plaws.
Siv lub thawv riam lossis qee yam zoo sib xws, ntsaws rooj plaub qhib ib sab ntawm lub micro-b USB chaw nres nkoj fais fab raws li pom hauv daim duab.
Ua haujlwm koj txoj kev ncig rov ua cov kauj ruam no ntawm txhua lub ces kaum.
Thaum tag nrho cov ces kaum tau xoob tshem tawm sab saum toj ntawm rooj plaub (sab nrog LED).
Tshem cov yas txuas ntxiv rau lub laub khawm thiab tus hloov hloov, ua tib zoo saib xyuas kev qhia kom koj tuaj yeem tso rov qab rau tib txoj kev.
Txhawm rau tshem lub rooj tsavxwm los ntawm ib nrab hauv qab ntawm rooj plaub tuav mus rau ob lub RJ45 txuas thiab rub tawm thaum koj thawb rau ntawm rooj plaub. Lub rooj tsavxwm yuav tig rov tom qab tsuas yog txuas ntxiv mus thiab nws yuav tawm mus.
Kauj Ruam 4: Ntxiv 5 Volt Fais Fab Txhaj Tshuaj
Peb yuav tsum tau ntxiv cov coj mus ntxig rau 5 volts ncaj qha rau hauv lub rooj tsavxwm. Txij li lub micro-b USB txuas tawm ntawm kev ncav cuag peb tsuas yog siv VCC tus pin ntawm qhov loj dhau los ntawm qhov USB hom A jack (ib qho rau lub flash drive).
Siv lub xov hlau AWG me me ua 2 tus neeg dhia dhia txog 4 ntev, kab txaij thiab tin ob qho kawg.
Muab cov xov hlau txuas rau tus pin 1 thiab tus pin 4 ntawm USB hom A nkaus.
Kos tus hlau lead los ntawm tus pin 4 (sab ze rau RJ45 nkaus) nrog lub ntsej muag dub los qhia rau hauv av.
Muab lawv ob peb qhov sib tw kom lawv nyob ua ke thiab ua rau lawv hla dhau lub micro-b USB lub zog rau tam sim no.
Kauj ruam 5: Tshem tawm Motherboard
Hmoov tsis zoo, cov khoom seem peb xav tau rau POE tsis txuas nrog ib yam dab tsi ntawm lub rooj tsavxwm yog li txoj hauv kev nkag mus rau lawv yog kom tau mus rau sab nraum qab ntawm qhov txuas uas tau npog los ntawm sab saum toj ntawm niam ntawv. Txawm hais tias qhov no yog ib kauj ruam kuv xav kom zam nws tuaj yeem ua rau mob hnyav dua. Qhov tseeb tias lawv siv qhov zoo los ntawm lub qhov taub hauv qab ntawm lub rooj tsavxwm hauv qab los txuas rau lub rooj tsavxwm sab saum toj kom tshem tawm tau yooj yim dua.
Muaj ntau txoj hauv kev rau desolder cov khoom. Hauv qhov no, kuv yooj yim ntxiv cov laug rau lub taub hau, siv ntau dua cov cua sov nrog cov lus qhia dav siv cov hlau thiab tom qab ntawd "maj mam" txhuam nws xoob los ntawm lub hauv paus hauv qab.
Lub rooj tsavxwm yog qhov ua tau zoo thiab kuv tsis muaj teeb meem nrog cov pawm tshem tawm lossis rub tawm cov cim.
Cov cua sov tsim los ntawm qhov no kuj tseem tawg zoo nyob rau thaj chaw uas tsis cuam tshuam.
Kauj Ruam 6: Ntxiv POE Passthrough thiab 48 Volt Leads
"thauj khoom =" tub nkeeg "koj xav tau cov ncauj lus ntxaws ntxaws ntawm ib qib tshwj xeeb lossis tsuas yog xav saib tag nrho cov kev sim thiab ua yuam kev ntawm kev ua lub tswv yim no tshwm sim tom qab ntawd saib daim vis dis aus no.
Zoo siab hacking!
