Hauv kuv qhov kev coj ua, kev siv lub zog ntawm lub cuab yeej thiab tau txais daim duab los ntawm nws ntawm qhov kev ncua deb ntawm qhov hloov pauv tsis yog txoj haujlwm yooj yim tshaj plaws. Tshwj xeeb tshaj yog thaum cov tes hauj lwm txuas los ntawm ib daim hlau mus rau ntau lub koob yees duab ntawm qhov sib txawv.
Ib qho khoom siv ntau dua los yog tsawg dua khov rau ib ntus. Qee yam tsis tshua muaj, thiab qee yam yog ntau zaus, thiab qhov no yog dogma. Feem ntau qhov no daws tau ... yog lawm ... nrog qhov no:
Thiab yog tias tsis muaj tes tsim nyog ntawm sab nraud ntawm lub raj, koj yuav tsum tau nqa koj lub taub qab ntawm lub rooj zaum thiab taug kev / tsav / ya mus rau lub cuab yeej.
Nws yog qhov tsis txaus siab tshwj xeeb yog tias cov cuab yeej no nyob ib puag ncig hauv qab lub ru tsev lossis ntawm tus ncej ... lossis hauv chaw ua haujlwm nyob deb.
Txuag yog qhov tseem ceeb ntawm kev tswj xyuas chaw taws teeb. Qee lub sij hawm nasalnik pom lub koob yees duab / hloov / router ntawm Aliexpress thiab piav qhia vim li cas cov khoom siv no raug nqi 700 rubles, thaum qhov koj muab rau ntau dua 5k tuaj yeem ua haujlwm tsis yooj yim. Tshwj xeeb tshaj yog tias cov cuab yeej no twb muaj thiab cov neeg tuaj cuag koj ntawm lub hauv paus ntawm "Vim li cas nws tsis ua haujlwm rau peb?" Tus neeg siv khoom yeej ib txwm yog, tshwj xeeb tshaj yog thaum nws hu tsawg li tsawg tau. Thiab qhov no txhais tau hais tias qhov no suav f *** ing phem ntaus ntawv yuav tsum muaj qee yam kev ywj pheej thiab nws yog ib qho tsim nyog kom "kick" tau txawm tias ua ntej tus neeg siv tau ceeb toom nws.
Tswj PoE keyboards tau npaj los cawm qhov xwm txheej; hmoov zoo, lawv tau nthuav tawm hauv ntau qhov ntawm lub khw.
Thiab ntawm no yog qhov teeb meem tus naj npawb Ib: los ntawm leej twg, lossis ntau dua li saib xyuas, yog li yog tias lub cuab yeej tau daig, thawb lub zog rov pib dua cov lus txib ntawm PoE hloov chaw nres nkoj. Kev tsa thiab teeb tsa tus neeg rau zaub mov yuav tsum muaj lub cev txav thiab kho vajtse ntxiv.
Cia peb hais ntawm kuv qhov chaw: tsuas muaj 15 lub koob yees duab yees duab, lub kaw lus video thiab ... yog nws. Nyob rau tib lub sijhawm, 7 nyob ntawm qhov deb tsawg dua 100 m, ntxiv 5 txog 150, thiab lwm 3 ntawm qhov deb ntawm 200 m. Nws yog ib qho tsim nyog yuav tsum ua kom yooj yim rau cov infrastructure kom cov neeg tuaj yeem tuaj rau ntawm qhov chaw no nkaus xwb. tiv thaiv lub hom phiaj.
Txoj kev daws teeb meem yog qhov yooj yim heev - muaj qhov hloov pauv PoE uas tuaj yeem saib xyuas lub koob yees duab thiab rov pib lub zog ntawm qhov chaw nres nkoj, thiab tseem "mus txog" hla lub cable hla qhov deb ntawm 200+ meters.
mikrotic
Muaj ob daim ntawv pov thawj (MTCNA thiab MTCRE), kuv ob lub qhov muag thawj zaug poob rau Mikrotik. Cov chaw tsim khoom no muaj kev xaiv me me ntawm cov qauv nrog P index, piv txwv li,
IMHO, me me dhau los ntawm kev teeb tsa. Yuav ua li cas yog tias lub koob yees duab poob thiab nco ob peb pings? - rov pib dua!
Yuav ua li cas yog lub koob yees duab nyuam qhuav tuag? Mikrotik yuav txiav nws tawm txhua feeb? ..
Hauv kuv qhov kev coj ua, muaj ntau qhov tsis xws luag hauv CCR fais fab mov. Lub ntsiab lus ntawm PoE hloov pauv yog dab tsi yog tias nws muaj kev pheej hmoo siab poob lub zog hauv rau lub hlis? ...
Tsis tas li ntawd, kuv tsis pom cov ntaub ntawv uas Mikrotik tuaj yeem ua haujlwm nrog cov xov hlau ntev li 150+ meters ...
zyxel ua
Thaum kawm cov neeg sawv cev ntawm cov neeg muag khoom sib tw, kuv tuaj hla . Hloov los ntawm Zyxel GS1350 series. Nws raug nqi ntau dua Mikrotik, tab sis kuv tsis tau pom muaj teeb meem nrog Zyxel nrog "tsis muaj zog" cov khoom siv hluav taws xob.
Zuksel ua haujlwm rau GS1350 keyboards raws li tsim tshwj xeeb rau kev soj ntsuam video. Cov keyboards pom tias lub koob yees duab daig thiab reboot nws siv lub zog.
Stuck nrhiav txoj kev
Ua ntej kuv pib paub txog cov cuab yeej no, kuv xav txog tias qhov hloov pauv tau txheeb xyuas hom tsheb thiab sai li sai tau thaum cov kwj video xaus, qhov hloov pauv rov pib lub zog ...
Tab sis txhua yam ua tau yooj yim dua.
"Auto PD rov qab" tuaj yeem ua haujlwm hauv ob hom:
- LLDP, uas yog, lub cuab yeej nws tus kheej muab cov ntaub ntawv hais txog nws tus kheej, yog tias, ntawm chav kawm, lub cuab yeej txhawb nqa nws. LLDP cov lus teb tuaj, uas txhais tau hais tias cov khoom kho vajtse yog "muaj sia nyob". Yog tias tsis muaj lus teb, peb yuam "txiav" lub zog thiab tos kom teb.
- Ping. Qhov twg yooj yim dua? Pinging - Tsis teb - Rebooting!
Tus naj npawb ntawm pings yam tsis muaj lus teb, lub sijhawm rov pib dua thiab tus naj npawb ntawm lub zog rov pib dua yog configurable. Uas yog qhov tseeb heev, vim tias tsis muaj qhov taw tes hauv "kicking" cov khoom kho vajtse yog tias nws tsis pib zaum thib peb.
Tab sis kuv tsis to taub: dab tsi yog qhov tshwj xeeb hauv cov koob yees duab video NO?
Ua li no koj tuaj yeem saib xyuas txhua yam khoom siv network. Txawm yog ib tug uas tsis txhawb PoE.
Peb xaj cov khoom siv zoo li no los ntawm Aliexpress thiab txhua yam khoom siv network hloov mus rau PoE.
Yog tias lub gadget khov, qhov hloov pauv yuav rov pib lub zog rau qhov chaw nres nkoj thiab hauv cov cav peb yuav pom qee yam zoo li no:
233 Sep 07 17:24:41 DE interface: Port 4 - ReoLink link up 100M/F

Ntawm nplooj ntawv hais tias:
Kev siv Extended ntau hom nyob rau hauv cov keyboards no tso cai rau koj kom nce qhov siab tshaj plaws nyob deb ntawm cov khoom siv fais fab mus txog 250 meters.
Peb yog accustomed mus rau tsis ntseeg txog tej advertising daim ntawv qhia.
Kuv crimped ob kawg ntawm lub bay tshiab (305 meters) thiab daig ib qho rau hauv lub koob yees duab thiab lwm qhov rau hauv qhov hloov. Lub koob yees duab tsis tau tshem tawm ... zoo li xav tau ^_^
Kuv zaum, khawb lub taub dag, mus rau hauv qhov chaw, kos lub thawv "Kev nthuav dav", thiab ... kaum vib nas this ntawm kev ntsiag to - nruas yob ... lub koob yees duab pib ua haujlwm! Ntawm 305 meter!
Tsis muaj pob ntawv poob!
Yog li, GS1350 series hloov mus txog tsis tau tshaj tawm 250, tab sis ntau npaum li 305 meters!
Muaj tseeb, tej zaum qhov kev dag kuj yog nyob rau hauv qhov zoo ntawm cable:
Yog tias xav tau ntev dua, koj tuaj yeem txuas ob peb ntu ntawm cable los ntawm qee hom rov ua dua. Koj tseem tuaj yeem txuas lwm tus poe mus rau qhov kawg kom txuas ntau yam khoom siv.
Piv txwv li, ntawm UPVEL UP-215SGE (Kuv tsis tau txheeb xyuas tias nws ntseeg tau li cas. Kuv nyuam qhuav tuaj hla nws.) Nws yog nws tus kheej powered ntawm PoE thiab powers li ntawm PoE.
Tab sis qhov no yog ib lub ncauj lus cais rau cov xwm txheej tshwj xeeb, vim nws xav tau kev tsim qauv coj mus rau hauv tus account txhua yam.
Thaum qhov "Extended range" xaiv tau qhib, qhov chaw nres nkoj yuav cia li nruab 802.3at raws tu qauv thiab teeb tsa lub zog siv nyiaj rau 33W.
Tab sis nws tsim nyog teev qhov tseem ceeb nyob rau hauv rooj plaub uas txhua tus neeg siv khoom pib nquag noj ... Cov chaw nres nkoj uas muaj qhov tseem ceeb tsawg, thaum muaj qhov tsis txaus ntawm lub zog ntawm qhov hloov, yuav tau txais lub zog thov kawg.
xob tiv thaiv
Qhov teeb meem thib ob thaum tso cov khoom siv sab nraum zoov yog kev tiv thaiv los ntawm lub zog hluav taws xob.
ESD/Surge Protection Tus nqi:
ESD - 15 kV / 8 kV (Air / Sib cuag);
Surge - 4 kV (Ethernet Chaw nres nkoj).Nco tseg. ESD - kev tiv thaiv hluav taws xob hluav taws xob hluav taws xob, Surge -
tiv thaiv overvoltage. Yog tias muaj qhov tso tawm zoo li qub tshwm sim hauv huab cua mus txog 15
kilovolt, los yog 8 kV electrostatics nyob ze, los yog ib ntus surge
voltages mus txog 4 kilovolts - qhov hloov pauv muaj txoj hauv kev zoo ntawm kev muaj sia nyob xws li
teeb meem.
Zoo, muaj qee qhov ntawm rooj plaub los txuas rau hauv av.
Kuv vam tias kuv tsis tas yuav kuaj qhov no ^_^
Nruam PoE
Cov khoom siv hluav taws xob txawm tias lub cuab yeej tsis teb. Los ntawm lub neej ntawd qhov kev xaiv no tau qhib. Tsis txhob hnov ββββqab xyuas qhov kev xaiv no ua ntej hloov kho lub firmware ntawm koj lub koob yees duab. Txwv tsis pub nws yuav tsis kaj siab ...
Cisco zoo li CLI
Rau cov neeg nyiam console, nrog rau txhawm rau ua kom lub teeb tsa, koj tuaj yeem siv Cisco-style CLI paub.
Yog tias koj tsis siv, piv txwv li, telnet / snmp thiab lwm yam kev cai, ces kuv pom zoo kom kaw lawv kom muaj kev ruaj ntseg ntawm lub cuab yeej.
Tsis muaj ib tug yoov nyob rau hauv cov tshuaj pleev ...
Qhov hloov pauv muaj cov ntawv qhia zaub mov "Cloud Management"
Tab sis thaum peb sim sau npe peb tau txais qhov no
Tam sim no kev txhawb nqa rau cov khoom siv no yog tseem tsis tau qhib. Cov chaw tsim khoom cog lus tias yuav ntxiv lawv rau xyoo 2020. Nyob rau tib lub sijhawm, koj yuav tsis tas yuav hloov kho qhov hloov firmware!
xaus
Lub Zyxel GS1350 yog tam sim no tsuas yog hloov pauv uas tau txaus siab rau kuv qhov kev thov:
- tswj nrog cov txheej txheem txheej txheem ntawm kev ua haujlwm
- cable ntev 200+ meters tsis muaj pob qij txha
- saib xyuas thiab rebooting PoE cov neeg siv khoom
- simplicity thiab yooj ntawm configuration.
Tej zaum muaj lwm yam kev daws teeb meem ntawm kev ua lag luam uas yuav ua tau raws li kuv xav tau, tab sis kuv tseem tsis tau pom lawv.
Kuv caw cov neeg uas xav tham txog tsab xov xwm rau Telegram hauv kev sib tham kuv tsim:
1. - Thematic tham ntawm Zyxel
2. - Thematic tham ntawm Mikrotik
