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 includes 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 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.
Ports can be combined together to create multi-link load sharing 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.
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).
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 videoconference.
D-Link Green technology
The DGS-1224T implements D-Link Green technology, resulting in reduced power consumption and heat dissipation. The switch has adopted the latest silicon technology, which helps lower your power consumption usage. If a port does not have a cable link or the connected device is powered down, the port goes to "sleep mode", reducing power consumption and saving energy. In a standard work day scenario in which PCs are used 10 hours a day and powered down for 14 hours, the DGS-1224T can provide power savings of up to 23% when compared to a D-Link conventional switch.
Protecting the environment for a better tomorrow
The incorporation of D-Link Green technology into DGS-1224T switch re-emphasizes D-Link's strong commitment to protecting the environment and leading the development of eco-friendly products. DGS-1224T complies with RoHS (Restriction of Hazardous Substances) and WEEE (Waste Electrical and Electronic Equipment) directives. RoHS directives restrict the use of specific hazardous materials during the manufacture of electrical and electronic goods, while WEEE directives apply standards for proper disposal and recyclable packaging to help reduce wastage.
Secure your network
The DGS-1224T provides a robust set of security features normally found only in fully managed switching solutions. They are equipped with the D-Link Safeguard Engine to protect the CPU from malicious attacks. When frames enter the switch, the D-Link Safeguard Engine detects and blocks broadcast, multicast, and unicast flooding, which can overload a CPU and bring network traffic to a halt. In addition, the switches provide support for secure encrypted 802.1X Port-based Authentication, Broadcast Storm Control, and up to 256 static MAC address entries.
IEEE 802.1Q VLAN tagging
VLANs allow your network to be segmented into Departmental, Hierarchical, and Security groups and place a "tag" in a frame to identify which VLAN it belongs to. This allows 802.1Q-compliant devices to work seamlessly together to manage VLAN traffic.
Asymmetric VLANs are also supported by the DGS-1224T. With this feature enabled, VLAN groups can send information to each other without the traffic going through a router or a Layer 3 switch. This eliminates expense and maximizes efficiency while maintaining security.
802.1p priority tagging or DSCP-based QoS
The DGS-1224T allows users to prioritize traffic based on 802.1p or DSCP-based (Differentiated Services Case Point) QoS. Port-based QoS prioritizes all port traffic with one value, while 802.1p classifies frames according to their VLAN tag. DSCP-based QoS prioritizes traffic according to its IP header. DSCP-based QoS and 802.1p priority tagging prioritizes traffic such as VoIP as it enters the switch, ensuring that your data is always clear and jitter-free.
The DGS-1224T supports Static Link Aggregation, which "trunks" multiple ports together to function as a single, high-bandwidth channel. When a high-bandwidth channel is needed to uplink to another switch, link aggregation makes this process simple and hassle-free.
Jumbo frame support
Jumbo frame support is designed to improve network throughput and significantly reduce the CPU utilization of large file transfers. This is accomplished by enabling larger, more efficient payloads per packet. The DGS-1224T supports Jumbo Frames up to 10KB in size.
IGMP snooping allows for the forwarding of multicast packets, such as streaming audio and video, without increasing network congestion. By snooping IGMP registration information within a frame, a list of workstations in the multicast group is created. The switch uses this list to intelligently forward packets to the appropriate workstations.
Because your connection is just as important as the switch itself, the DGS-1224T is designed with a cable diagnostic feature that detects transmission errors and the condition of cables attached to the switch's Gigabit copper ports. Cable Diagnostics make it easier to troubleshoot cabling issues through a web-based interface and keep all connections up.
Advanced management featuresProduct Highlights
The DGS-1224T supports SNMP v1, a useful tool in managing and controlling SNMP-supported network devices. SNMP enables the switches to provide valuable information about the switch's status and send traps on abnormal events. This sharing of vital management information saves time and money.
