This enables extended secure access in areas outside the wiring closet (such as conference rooms) Web-based authentication Web-based authentication provides network admission control through web browser to any host devices and operating systems STP Bridge Protocol Data Unit (BPDU) Guard A security mechanism to protect the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port. This avoids accidental topology loops STP Root Guard This prevents edge devices not in the network administrator’s control from becoming Spanning Tree Protocol root nodes STP loopback guard Provides additional protection against Layer 2 forwarding loops (STP loops) DHCP snooping Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as DHCP Servers. IP Source Guard (IPSG) When IP Source Guard is enabled at a port, the switch filters out IP packets received from the port if the source IP addresses of the packets have not been statically configured or dynamically learned from DHCP snooping. This prevents IP address spoofing. Dynamic ARP Inspection (DAI) The switch discards ARP packets from a port if there are no static or dynamic IP/MAC bindings or if there is a discrepancy between the source or destination addresses in the ARP packet. This prevents man-in-the-middle attacks. IP/MAC/Port Binding (IPMB) The preceding features (DHCP Snooping, IP Source Guard, and Dynamic ARP Inspection) work together to prevent DOS attacks in the network, thereby increasing network availability Secure Core Technology (SCT) Makes sure that the switch will r

This prevents IP address spoofing. Dynamic ARP Inspection (DAI) The switch discards ARP packets from a port if there are no static or dynamic IP/MAC bindings or if there is a discrepancy between the source or destination addresses in the ARP packet. This prevents man-in-the-middle attacks. IP/MAC/Port Binding (IPMB) The preceding features (DHCP Snooping, IP Source Guard, and Dynamic ARP Inspection) work together to prevent DOS attacks in the network, thereby increasing network availability Secure Core Technology (SCT) Makes sure that the switch will r

Popis produktu Ubiquiti UniFi Switch Flex 2.5G PoE je kompaktní switch určený pro rozšíření sítě v domácích i kancelářských prostředích, zejména pak pro připojení napájených zařízení. Nabízí 8x 2.5Gbit porty s podporou PoE 802.3af/at/bt (POE++ 60W), které umožňují snadnou integraci zařízení s vyššími přenosovými rychlostmi, jako jsou moderní přístupové body, servery nebo NAS úložiště. Celkový PoE budget dosahuje až 196W v případě napájení DC adaptérem. Pokud je switch napájen pomocí PoE, pohybuje se PoE budget v rozmezí 12W - 57W. Switch podporuje správu prostřednictvím aplikace UniFi Network, což usnadňuje jeho konfiguraci a dohled nad sítí. Jako uplink slouží combo port 10G RJ45 / SFP+. Jednou z jeho klíčových funkcí je podpora napájení přes ethernet, což znamená, že zařízení lze napájet přímo přes síťový kabel pomocí PoE vstupu na uplink portu (90W 802.3bt / POE+++), případně pak pomocí 54V DC / 3.9A adaptéru (adaptér není součástí balení). Přestože je uplink port combo, lze nejen využít jen jeden z portů, ale také využít metalický port pro napájení a optický port pro data. Svým minimalistickým designem je ideální pro umístění na pracovním stole nebo montáž na stěnu. S volitelně dokoupeným kitem je možná montáž na DIN lištu. Je plně kompatibilní s produkty UniFi a umožňuje snadné škálování podle potřeby. Pro správu zařízení je potřeba aplikace UniFi Network v9.0.108 a novější.

GPERx6 umožňuje rozšířit napájení a optické vlákno společně pomocí jediného hybridního kabelu. Na druhém konci jej GPERx6 přehledně rozdělí: • SFP+ pro další dálkové uplinky • PoE-out pro napájení kamer nebo přístupových bodů • DC výstupy pro zařízení IoT nebo specializovaná zařízení GPERx6 eliminuje problémy s aspekty nepříznivých meteo podmínek při venovních instalacích, zjednodušuje nasazení a nabízí: • 3 gigabitové ethernetové porty s PoE-in (#1) a PoE-out (#2 a #3) • 3× 10G SFP+ klece pro dálkové optické kabely • 3 DC výstupy pro zařízení, která nepoužívají PoE, například IoT zařízení • Odolný kryt IP66 s praktickým montážním hardwarem • Speciální 10G switch čip (testovaný v oblíbených ISP zařízeních, jako je netPower Lite 7R) Tedy řešení, umožňující správu napájení a dat na dlouhé vzdálenosti (1–2 km) i v těch nejnáročnějších scénářích. Konktétní případové nasazení: Jedním z možných použití GPERx6 je možnost přerušit stávající optické vedení a připojit zákazníky podél trasy (proto jsou k dispozici 3 porty SFP+ – vstupní vedení, zákaznické místo, výstupní vedení). Jedná se o častý problém, kdy optické vedení vede podél nemovitosti, ale poskytovatel internetových služeb odmítá připojit konkrétní nemovitost, protože nechce přerušit optické vedení. Výhoda hybridních kabelů Díky hybridním optickým a metalice se GPERx6 stává životně důležitým zdrojem energie a dat: • Optická vlákna přenášejí vaše vysokorychlostní uplinky. • Měděné vodiče dodávají stejnosměrný proud.
