Kev xa khoom sai 120W Sab Hauv Hluav Taws Xob IEEE802.3af / ntawm 4 Chaw nres nkoj Ethernet Hloov POE

Nqe lus piav qhia:

HDV-4GE POE + 2GE UP-ND yog tus qauv PoE powered Ethernet hloov tsim thiab tsim los ntawm HDV kho qhov muag khoom sib txuas lus. Nws txais qhov tseeb high-speed Ethernet hloov nti thiab ultra-siab backplane bandwidth tsim. Nws muaj peev xwm ua cov ntaub ntawv muaj zog thiab txhim kho cov ntaub ntawv sib kis tau zoo.Supports 4 * 10/100/1000Mbps Ethernet RJ45 chaw nres nkoj nrog PoE muaj nuj nqi thiab 2 * 10/100/1000Mbps Ethernet uplink RJ45 chaw nres nkoj, txhua qhov chaw nres nkoj txhawb nqa nws pib rollover muaj nuj nqi (Auto MDI / MDIX). Ntawm lawv, 4 qhov chaw nres nkoj nrog PoE muaj nuj nqi, tag nrho cov kev txhawb nqa IEEE 802.3af / ntawm tus qauv PoE fais fab mov, uas tuaj yeem siv los ua cov khoom siv hluav taws xob rau Ethernet. Lub zog siab tshaj plaws ntawm ib qho chaw nres nkoj yog 30W thiab lub zog siab tshaj plaws ntawm tag nrho lub tshuab yog 120W. Nws tuaj yeem ntes thiab txheeb xyuas IEEE 802.3af / ntawm tus qauv Powered khoom.Powered los ntawm lub network cable, nws txhawb nqa 250 meters ntawm kev sib kis mus ntev thiab txhawb nqa qhov tseem ceeb ntawm cov khoom siv hluav taws xob.

Nta:
• Chaw nres nkoj Performance
Muab 4 * 10/100/1000Mpbs RJ45 adaptive high-speed forwarding data port;
Muab 2 * 10 / 100 / 1000Mpbs RJ45 uplink chaw nres nkoj;
Txhua qhov chaw nres nkoj txhawb MDI / MDIX tsis siv neeg rollover thiab nws pib-kev sib tham, thiab txhawb IEEE 802.3x full-duplex flow control thiab Backpressure ib nrab-duplex flow control;
• PoE Power Performance
4 * 10 / 100 / 1000Mpbs RJ45 chaw nres nkoj txhawb PoE + fais fab mov, ua tau raws li qhov yuav tsum tau muaj ntawm PoE fais fab mov hauv kev saib xyuas kev ruaj ntseg, kev sib tham hauv xov tooj, kev them nyiaj wireless thiab lwm yam xwm txheej;
Ua raws li IEEE 802.3af / ntawm PoE fais fab mov tus qauv, qhov siab tshaj plaws PoE tso zis zog ntawm tag nrho lub tshuab yog 120W, thiab qhov siab tshaj plaws PoE tso zis zog ntawm ib qho chaw nres nkoj yog 30W;
Tsis siv neeg txheeb xyuas PoE cov cuab yeej siv hluav taws xob tsis muaj kev puas tsuaj rau cov khoom siv uas tsis yog PoE;
Qhov chaw nres nkoj PoE txhawb nqa lub luag haujlwm tseem ceeb. Thaum lub zog ntxiv tsis txaus, nws lav lub zog ntawm qhov chaw nres nkoj siab ua ntej kom tsis txhob overloading lub cuab yeej;
• Cov khoom siv ruaj khov thiab txhim khu kev qha
Kev siv hluav taws xob tsawg thiab tsim kev ntsiag to ntawm tus tswv kom ua haujlwm ruaj khov ntawm cov khoom;
Txais yuav tus kheej-tsim fais fab mov thiab tsim redundant heev los muab lub zog ruaj khov PoE mus sij hawm ntev;
Cov cuab yeej ua tau raws li lub teb chaws CCC cov qauv, ua tau raws li qhov yuav tsum tau muaj kev nyab xeeb, thiab muaj kev nyab xeeb thiab siv tau;
• Kev ua haujlwm yooj yim thiab muaj zog scalability
Yooj yim thiab yooj yim siv, tsis muaj teeb tsa, ntsaws thiab ua si, muaj zog sib xws;
Kev sib kis ceev ceev, cov ntaub ntawv tsis muaj pob ntawv poob, hloov pauv tau yooj yim, kom lub network tsis txwv los ntawm kev teeb tsa ntawm cov kab hluav taws xob, txuag cov neeg siv khoom;
Ua tau raws li lub network ib puag ncig uas yuav tsum muaj lub zog siab PoE;
Nws yog tsim rau nyiaj txiag, tsoom fwv cov koom haum, tsev so, khw malls, tsev kawm ntawv, tsev kho mob thiab cov lag luam me thiab nruab nrab los tsim kev sib raug zoo network;
