D-Link 10/100/1000Mbps 52-Port Managed Gigabit Switch

Product Overview The DGS-3000 Series Gigabit L2 Managed Switches feature a variety of ports, including 10/100/1000BASE-T RJ-45 ports, 1G SFP ports, and 10G SFP+ ports for increased network bandwidth. Surge protection, advanced Layer 2 functions, and a suite of security and management tools make the DGS-3000 Series Gigabit L2 Managed Switches ideal for Metro Ethernet and campus applications.

Multi-Gigabit Performance
The D-Link DGS-3000-52X 48-Port Layer 2 Managed Gigabit Switch comes with a variety of port types, including 1 G RJ-45 ports, 1 G SFP ports, and 10G SFP+ ports, with all models offering a minimum of at least 2 1 G SFP ports. The D-Link DGS-3000-52X 48-Port Layer 2 Managed Gigabit Switch offers 4 10G SFP+ ports for improved bandwidth and fault tolerance.

Efficient and Resilient Networking
The D-Link DGS-3000-52X 48-Port Layer 2 Managed Gigabit Switch supports up to 6 kV surge protection on all Ethernet ports, protecting the switch from power surges due to lightning strikes or faulty electrical cabling. The DGS-3000-52X supports ITU-T G.8032 Ethernet Ring Protection Switching (ERPS), which allows 50-millisecond failover in the event of a failure of one of the rings, minimising service disruption. The D-Link DGS-3000-52X 48-Port Layer 2 Managed Gigabit Switch also supports IEEE 802.1AX and 802.3ad Link Aggregation, which allows grouping of multiple ports to provide redundancy and load balancing in mission-critical environments.

Quality of Service
The D-Link DGS-3000-52X 48-Port Layer 2 Managed Gigabit Switch implements a rich set of multilayer QoS/CoS features to ensure that critical network services such as VoIP, video conferencing, IPTV, and IP surveillance are given high priority. Flexible packet classification can be based on various header fields or user-defined packet content to help administrators prioritise network traffic. Traffic Shaping features guarantee bandwidth for these critical services when the network is busy. Multilayer QoS/CoS features let IT managers arrange network resources more efficiently in enterprise environments.

Identity-driven Network Policies
The D-Link DGS-3000-52X 48-Port Layer 2 Managed Gigabit Switch supports authentication mechanisms such as 802.1X port-based Access Control, Web-based Access Control (WAC), and MAC-based Access Control (MAC) for strict access control to network resources. After authentication, individual policies such as VLAN membership, QoS policies, and ACL rules can be assigned to each host. Additionally, the switches support Microsoft NAP (Network Access Protection), which allows network assets to be protected from compromised computers by enforcing compliance with network health policies.

Manageability
D-Link Single IP Management (SIM) simplifies and speeds up management tasks, allowing multiple switches to be configured, monitored, and maintained from any workstation running a web browser and with network connectivity. All switches can be managed as a virtual stack, allowing physically separate switches to be managed using a single IP address. The D-Link DGS-3000-52X 48-Port Layer 2 Managed Gigabit Switch also supports management tools such as a Web UI, SSH, Telnet, and console, and standards-based protocols such as SNMP, RMON, and SSL.

Security and Authentication
The D-Link DGS-3000-52X 48-Port Layer 2 Managed Gigabit Switch offers user and device authentication, including hostbased authentication and authorisation, which provide the option to finely control network access for each device on the network. Advanced features such as RADIUS accounting allow the switches to be integrated with backend systems for billing or advanced access control. TheD-Link DGS-3000-52X 48-Port Layer 2 Managed Gigabit Switch also supports address and interface binding features such as IP-MAC-Port Binding and ARP Spoofing Prevention to protect against Man-in-the-Middle or ARP Spoofing attacks.
