Product Description:
24-Port Smart Copper Gigabit Switch With 2 Combo SFP (Mini GBIC)
The DGS-1224T copper Gigabit Smart Switch presents a cost-effective solution for the small and medium business to implement Gigabit Ethernet packet switching with easy fine-tuning of network performance and security. This switch comes with 24 10/100/1000BASE-T copper Gigabit ports and 2 combo SFP (Mini GBIC) ports for flexible fiber Gigabit connection. Port trunks are provided for server deployment and network backbone attachment, while functions important for bandwidth intensive applications such as Priority Queues and VLANs are supported to enable you to implement Quality of Service (QoS) and security without having to go through complex network management usually found in other managed switches.

24 Copper Gigabit Ports
24 Gigabit ports provide an inexpensive alternative solution to fiber-optic. Using your existing low-cost Cat. 5 copper twisted-pair wires as the transmission media, these ports allow you to instantly upgrade your servers to Gigabit capability without requiring you to install new, expensive fiber cables. All ports support 10/100/1000Mbps network speed auto-sensing, full/half duplex auto-negotiation and auto MDI/MDIX plug-and-play.

2 Combo SFP Slots for Flexible Fiber Connection
2 combo SFP (Mini GBIC) slots are provided for flexible fiber connection. You can select to install optional transceiver modules in these slots for short, medium or long distance fiber backbone attachment. Use of the SFP will disable their corresponding built-in 10/100/1000BASE-T connections.

Port Trunks for Aggregated Bandwidths
Ports can be combined together to create multi-link loadsharing aggregated bandwidths to a server or a network backbone. To expand the network, you can also make use of the port trunks to eliminate bottlenecks between the cascaded switches. The switch allows you to combine between 2 and 4
ports per trunk to create multiple port trunks.

VLANs for Enhanced Security & Performance
The switch support VLANs to let you improve security and bandwidth utilization by limiting the broadcast domains and confining intra-group traffic within their segments. To segment up the network, VLAN-supported workstations and servers that are connected to the switch can be grouped into different Virtual LANs (VLANs).

Quality of Service Support
The switch supports Layer 2 802.1p Priority Queue control to prioritize network packets. Classification of users data priorities can be based on a data packet Priority Queue. This QoS function support allows you to run bandwidth-intensive and delay-sensitive applications and to attach video servers to the switch for video conference.
