Physical Port

• 24-port 10/100/1000BASE-T Gigabit RJ45 copper with 802.3at PoE+ injector function
• 2 1000BASE-X mini-GBIC/SFP slots

Power over Ethernet

• 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
• 240-watt PoE budget
• Auto detects powered device (PD)
• Circuit protection prevents power interference between ports
• Remote power feeding up to 100m

Switching

• 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;

1. 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
2. Extend mode: Ports1 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 (IEEE802.3az)

Hardware

• 19-inch desktop size, 1U height
• LED indicators for PoE ready and PoE activity
• Ethernet Link Energy-saving technology

1. Link down power savings
2. Intelligent use of power based on cable length
