DGS-3630-52TC/SI
Prodotto nuovo
Overview
The DGS-3630 Series Layer 3 Stackable Managed Switches are designed for Small Medium Businesses (SMBs), Small Medium Enterprises (SMEs), larger Enterprises, and Internet Service Providers (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 switches can operate as core, distribution or access layer switches. High port densities, switch stacking, and easy management make the DGS-3630 Series switches ideal for a wide variety of business networking applications.
Standard and Enhanced Software Images
The DGS-3630 Series switches include the Standard Image (SI) software. For additional functionality, they may be upgraded to Enhanced Image (EI) software 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 adds support for 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 when 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 physical1 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 nine 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 sizes to be dynamically changed, so that switch functions can be optimized based on the use of the switch. There are three modes: IP Mode, LAN Mode, and L2 VPN Mode. These modes modify the sizes of the Layer 2 and 3 tables for optimum efficiency.
Switch and Link Failover
In addition to traditional Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP), and Multiple Spanning Tree Protocol (MSTP), the DGS-3630 Series switches also support advanced Ethernet failover redundancy technologies, such as ERPS and FlexLink. Ethernet Ring Protection Switching (ERPS) provides millisecond-level failover in a ring topology. FlexLink offers link failover on designated switch ports, providing link redundancy without STP or LBD.
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 traffic flooding caused by malicious attacks.
Versatile Management
The DGS-3630 Series switches can be managed by an industry standard Command Line Interface (CLI), an intuitive web-based Graphical User Interface (GUI), and the D-Link Network Assistant Utility. In addition, 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 switches 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 auto-image features can also be used to deploy multiple switches automatically, saving costs with larger deployments.
Power over Ethernet (PoE) Support
The DGS-3630-28PC and DGS-3630-52PC models feature Power over Ethernet, which allows PoE-powered devices to be powered by the switch through a standard Ethernet cable. Both models support the IEEE 802.3af PoE and IEEE 802.3at PoE+ standards, providing up to 30W of power per port. PoE effectively reduces deployment time for devices such as IP cameras, VoIP phones, and access points, and eliminates the cost for additional electrical cabling. Both models feature a 370W PoE power budget which can be increased to 740W when outfitted with the DPS-700 redundant power supply, allowing the switches to power even more devices. Additionally, an extended Link Layer Discovery Protocol (LLDP) automatically negotiates and manages the power feed to IEEE 802.3at PoE+ powered devices for optimal power distribution.
6 kV Surge Protection
The DGS-3630 Series switches feature built-in 6 kV surge protection on all PoE and non-PoE Ethernet access ports. This effectively protects the switches against sudden electrical surges caused events such as lightning strikes or unstable electrical current. Built-in 6 kV surge protection significantly reduces the chances of equipment being damaged from electrical surges, and effectively lowers maintenance costs by minimizing the need for expensive equipment repairs or replacement.
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 fan2 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.
1 Only DGS-3630 Series switches with the same image version can be physically stacked. For example, a DGS-3630 Series switch running the Standard Image can only be stacked with another DGS-3630 Series switch running the Standard Image.
2 For non-PoE models, by default, the fan speed is low. When the temperature inside the chassis exceeds 36 °C (97 °F), the fans switch to high speed until the temperature drops below 33 °C (91 °F). For PoE models, by default, the fan speed is low. When the temperature inside the chassis exceeds 37 °C (98 °F), the fans switch to high speed. When the temperature in the chassis reaches between 22 °C to 27 °C (71 °F to 80 °F), the fans switch to medium speed. When the temperature inside the chassis drops below 22 °C (71 °F), the fans switch to low speed.
