The DGS-3630 Series 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 DACs to make up to 432 Gigabit Ethernet ports available, allowing switching capacity to be increased with demand. In addition to traditional Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP), and Multiple Spanning Tree Protocol (MSTP), the DGS-3630 Series also supports advanced Ethernet failover redundancy technologies, such as ERPS and FlexLink while Ethernet Ring Protection Switching (ERPS) provides millisecond-level failover in a ring topology.

The DGS-3630 Series provides the D-Link Network Assistant (DNA) 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.

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.
