PLANET FGSD-1821P on desktop-mallinen 18-porttinen PoE+ kytkin, jonka Ethernet-porteista 16x on varustettu PoE virransyöttötuella kokonaiskapasiteetin ollessa 185W. Kytkimen 10/100 PoE-porttien lisäksi laitteessa on 2x Gigabitin uplink-porttia sekä yksi jaettu SFP-moduulipaikka valokuituoptiikalle.

Kytkimessä on lisäksi ”Extended” toimitila, joka mahdollistaa 10Mbit/s Ethernet-yhteydet sekä PoE- virransyötön jopa 250m etäisyyksille. Erityisen hyödyllinen tämä on valvontakamera-verkoissa, joissa Ethernet-kaapeli saattaa ylittää standardin 100m pituuden. VLAN-toimitila on myös DIP-kytkimellä valittavissa, joten kytkin soveltuu erinomaisen hyvin kameravalvontaverkkoihin. Pakkaus sisältää laitteen lisäksi 19″ räkiraudat.

Tekniset tiedot:
• 16x 10/100BASE-TX RJ45 ports with IEEE 802.3at PoE+ injector function (ports 1:16)
• 2x 10/100/1000BASE-T Gigabit RJ45 ports interfaces (ports 17-18)

• Supports PoE power up to 32W for each PoE port, with a total PoE budget of 185W
• Each port supports 55 DC power to PoE powered device
• Auto detects powered device (PD)
• Supports PD alive function
• Circuit protection prevents power interference between ports
• Remote power feeding up to 100m in standard mode with 250min extend mode
• Hardware-based 10/100Mbps and 10/100/1000Mbps auto- negotiation and auto MDI/MDI-X

• Integrates address look-up engine, supporting 16k absoluteMAC addresses
• 16k jumbo frame supports 1000Mbps speed
• Hardware-based DIP switch for Standard, VLAN or Extend mode selection
– VLAN mode: Ports 1 to 16 cannot communicate with each other, but can communicate with the uplink ports 17 to 18 and SFP port 17
– Extend mode: Ports 1 to 8 have data rate of 10Mbps. The farthest transmission distance is up to 250 meters and all ports can communicate with each other
– VLAN mode is to isolate ports to prevent broadcast storm and defend DHCP spoofing
