PLANET GSW-2620HP on metallikoteloitu 26-porttinen
Gigabitin 19" kytkin, joka on varustettu 24x PoE+
kupariportilla sekä kahdella Gigabitin SFP-modulipaikalla.
Kytkimen PoE-virransylttökapasiteetti on 240W.
Tekniset tiedot:
• 24x 10/100/1000BASE-T Gigabit RJ45 copper with 802.3at
PoE+ injector function
• 2x 1000BASE-X mini-GBIC/SFP slots
• Complies with IEEE 802.3af/at Power over Ethernet end-span
PSE
• Up to 24 ports of IEEE 802.3af/802.3at devices powered
• Supports PoE power up to 30.8 watts for each PoE port
• Each port supports 52V DC power to PoE powered device
• 240W PoE budget
• Auto detects powered device (PD)
• Circuit protection prevents power interference between
ports
• Remote power feeding up to 100m
• Hardware-based 10/100/1000Mbps auto-negotiation and auto
MDI/MDI-X
• Flow control for full duplex operation and back pressure
for half duplex operation
• Integrates address look-up engine, supporting 8K absolute
MAC addresses
• 9K jumbo frame supports all speeds (10/100/1000Mbps)
• IEEE 802.1Q VLAN transparency
• Hardware DIP switch for Standard, VLAN and Extend mode
selection;
- VLAN mode: Ports 1 to 22 cannot communicate with each
other, but can communicate with the uplink ports 23 to 24
and SFP ports 25 to 26
- Extend mode: Ports 1 to 8 have data rate of 10Mbps. The
farthest transmission distance up to 250 meters and all
ports can communicate with each other.
- The DIP switch can isolate ports to prevent broadcast
storm and defend DHCP spoofing
- Automatic address learning and address aging
Supports Energy-Efficient Ethernet (EEE) function (IEEE
802.3az)
• 19" desktop size, 1U height
• LED indicators for PoE ready and PoE activity
• Ethernet Link Energy-saving technology
• Link down power savings
• Intelligent use of power based on cable length
