The DGS-3630 Series Layer 3 Stackable Managed Switches are designed for Small Medium Businesses (SMBs), Small Medium Enterprises (SMEs), larger Enterprises, and ISPs. They deliver high performance, flexibility, fault tolerance, and advanced software features for maximum return on investment. With Gigabit Ethernet RJ45 and SFP ports, 10 GbE SFP+ ports, advanced security features, and advanced Quality of Service (QoS), the DGS-3630 Series can act as core, distribution or access layer switches. High port densities, switch stacking, and easy management make the DGS-3630 Series suitable for a variety of applications. Standard and Enhanced Software Images The DGS-3630 Series switches include the Standard Image (SI) software, and for additional functionality, they may be upgraded to Enhanced Image (EI) with a separately ordered license upgrade. The Standard Image provides core SMB and SME functionality, such as L2 switching, entry-level routing, L2 multicast, advanced QoS, Operations, Administration, and Maintenance (OAM), and robust security features. The Enhanced Image includes all the features from the Standard Image, and also supports full L3 routing for Enterprise integration, including OSPF, BGP, VRF-Lite and L3 multicast. This approach allows I.T. managers to deploy a lower cost L2/L2+ solution today, and upgrade to a L3 solution in the future if networking needs change and a full dynamic routing solution is required. High Availability and Flexibility The DGS-3630 Series switches support stacking technology, which combines multiple switches to form a single physical or virtual stack. This increases redundancy over multiple physical units, simplifies management, and provides a single IP address to manage all members in the stack. Up to 9 switches can be stacked using Direct Attach Copper (DAC) or fiber optic cables to make up to 432 Gigabit Ethernet ports available, allowing switching capacity to be increased with demand. The Switch Resource Management (SRM) feature allows the hardware table size to be changed, so that switch functions can be optimized based on the use of the switch. There are 3 modes: IP Mode, LAN Mode, and L2 VPN Mode, which modify the size of the Layer 2 and 3 tables for optimum efficiency. Security, Performance and Availability The DGS-3630 Series switches provide a complete set of security features including multi-layer Access Control Lists (ACLs) and 802.1X user authentication via TACACS+ and RADIUS. The DGS-3630 switches also offer extensive VLAN support, including GVRP and 802.1Q VLAN to enhance security and performance. A robust set of QoS features help ensure that critical network services such as Voice over IP and video conferencing are given high priority through the network. The D-Link Safeguard Engine increases the switches' reliability, serviceability, and availability by preventing malicious flooding traffic caused by worms or virus attacks. D-Link Green Technology The DGS-3630 Series switches feature D-Link Green technology, which includes a power-saving mode, smart fan feature, reduced heat dissipation, and cable length detection. The power-saving feature automatically powers down ports that have no link or link partner, and ensures that LEDs are shut off when not needed. The smart fan3 feature allows for the built-in fans to automatically turn on only at a certain temperature, providing continuous, reliable, and ecofriendly operation of the switch.
