The DGS-3630 Series Layer 3 Stackable Managed Switches are a range of switches designed for Small Medium Businesses (SMBs), Small Medium Enterprises (SMEs), enterprises, and ISPs. They deliver high performance, flexibility, fault tolerance, and advanced software features for maximum return on investment. With Gigabit Ethernet SFP, 10 GbE SFP+, 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, Enhanced, and MPLS Images

The DGS-3630 Series is designed for use with three different software images: the Standard Image (SI), the Enhanced Image (EI), and the MPLS Image (MI). 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 supports full L3 routing for enterprise integration, including OSPF, BGP, VRF-Lite and L3 multicast. The MPLS Image offers VPN services for ISPs, including IS-IS and MPLS L2/L3 VPN. With multiple software images, only the required features need to be installed, providing a flexible approach to software management.

High Availability and Flexibility

The DGS-3630 Series includes stacking technology, which allows multiple switches to be combined 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 combined using Direct Attach 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 &Availability

The DGS-3630 Series provides 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 Series also offers 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 switchs reliability, serviceability, and availability by preventing malicious flooding traffic caused by worms or virus attacks.

D-Link Green Technology

The DGS-3630 Series features 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.

Versatile Management

The DGS-3630 Series provides the D-Link Network Assistant Utility, an industry-standard CLI, and an intuitive web-based management interface that enables administrators to set up and remotely manage their networks. Support for SNMP allows centralized management of a large number of devices and out-of-band management is available via a dedicated console port. A mini-USB console port allows the DGS-3630 Series to be managed without any extra connectors, and a USB Type A port can be used to store logs, configuration, and firmware images. The DHCP auto-configuration and autoimage features can also be used to deploy multiple switches automatically, saving costs for mass deployment.
