Gigabit Ethernet PoE-võrkude tsentraliseeritud toitehaldus
Selleks, et hõlbustada 32 W PoE toite võrgu rakendusi Gigabit kiirusega ülekandega, on GSD-2022P varustatud 16 10/100/1000BASE-T Gigabit Ethernet porti, 2 täiendavat Gigabit TP porti ja 2 1000BASE-X SFP liidest koos sisemise toitesüsteemiga. Kokku 185 vati PoE-eelarvega on see varustatud suure jõudlusega Gigabit IEEE 802.3af PoE (kuni 15,4 W) ja IEEE 802.3at PoE+ (kuni 32 W) võimekusega kõigis portides.
Tänu usaldusväärsele kommutatsioonitehnoloogiale ja täiustatud võrgufunktsioonidele optimeerib GSD-2022P selliste võrguseadmete, nagu traadita pääsupunktid, VoIP-telefonid ja turvakaamerad, paigaldamist ja toitehaldust. Samuti vähendab see kasutuselevõtu aega ja kulusid, integreerides toite- ja andmevahetuse ühte seadmesse ning vabastades võrguseadmed pistikupesade asukoha piirangutest ja täiendavast vahelduvvoolu juhtmestikust.
Täiuslik integreeritud lahendus PoE IP-seire jaoks
GSD-2022P pakub ideaalselt turvalist valvesüsteemi madalamate kogukuludega. GSD-2022P pakub 16 10/100/1000Mbps 802.3at PoE+ porti, mis suudavad korraga 16 IEEE 802.3af/IEEE 802.3at PoE+ IP-kaamerat piisava PoE-toitega varustada. Samuti on võimalik ühendada üks 16-kanaliline NVR või kaks 8-kanalilist NVR-i, mis on ühendatud ülespoole magistraalvõrku ja seirekeskusesse. Sellise suure jõudlusega kommutaatorite arhitektuuri abil saab PoE IP-kaamerate salvestatud videofaile salvestada NVR-süsteemi, kus administraator saab kontrollida ja jälgida valvepilte nii kohalikus LANis kui ka kaugemates kohtades.
Ethernet-andmeedastuskauguse laiendamine
DIP-lüliti pakub töörežiime "Standard", "VLAN" ja "Extend".
GSD-2022P töötab tavalise IEEE 802.3at PoE+ lülitina "Standard" töörežiimis.
"VLAN" töörežiimil on portipõhine VLAN-funktsioon, mis aitab vältida IP-kaamera multisaate- või ringhäälingutormi üksteise mõjutamist.
Töörežiimis "Extend" töötab GSD-2022P portide kaupa 10Mbps duplekskasutuses, kuid toetab 20-vattist PoE-võimsust kuni 250 meetri kaugusele, ületades Ethernet UTP-kaabli 100m piirangu.
Selle uhiuue funktsiooniga pakub GSD-2022P täiendavat lahendust 802.3at PoE+ kauguse laiendamiseks, säästes seega Ethernet-kaabli paigaldamise kulusid.
Powered Device Alive Check
The GSD-2022P adopts not only Power over Ethernet technology, but also automated PD monitoring and real-time PoE status.
The PD alive check feature is applied in Standard, VLAN and Extend modes. After the PoE of the port is powered on, the device starts to detect whether the port is transmitting data. If the port does not transmit data and the duration exceeds a specific time, PoE will automatically power off and then re-power. It also will greatly enhance the network reliability in that the PoE port will reset the PD power, thus reducing administrator’s management burden.
Flexible Extension Solution
The two mini-GBIC slots built in the GSD-2022P are compatible with the 1000BASE-SX/LX SFP (Small Form-factor Pluggable) fiber transceiver, uplinked to backbone switch and monitoring center in long distance. The distance can be extended from 550 meters (multi-mode fiber) to 10/20/30/40/50/60/70/120 kilometers (single-mode fiber or WDM fiber). They are well suited for applications within the enterprise data centers and distributions.
