DGS-6604

Description
The DGS-6600 series chassis switches are intelligent, high-performance and multi-layer devices designed for local and regional networks. This series of switches is the ideal solution for situations where continuous operation of network applications and a high level of performance, security and management are required. 

With a flexible, modular architecture and industry standards, these switches allow for easy network scaling, making it a profitable investment for enterprises.

The DGS-6600 series switches are equipped with a high-speed switching fabric, advanced software features, including IPv6 support. These switches provide high performance, fault tolerance and are ideal not only for solving current problems, but also for tasks that are relevant in the near future.

High fault tolerance
DGS-6604 is equipped with 1 slot for installation of the control module. With 4 redundant load sharing power supplies and hot-swappable fan tray, the DGS-6604 is highly fault-tolerant and ideal for mission-critical network applications.

DGS-6604 
• Chassis with 4 slots 
• 1 slot for control module
• 3 slots for installing user-selected modules 
• Up to 4 slots for 3+1 redundant power supplies
• Replaceable fan assembly and dust filter
• Switching matrix 576 Gbps

Versatile Modular Design
The DGS-6600 series is represented by two models:

The DGS-6604 is a chassis with 4 slots, three of which are used to install user-selected modules. In addition, there are 4 slots for redundant power supplies and one slot for a replacement fan tray.

DGS-6608 is an 8-slot chassis. Two slots are used to install redundant control modules, and the rest are for user-selected modules. In addition, there are 8 slots for installing redundant power supplies and one slot for installing a replacement fan tray.

This modular architecture enables network scalability by installing additional modules that can be easily replaced at any time depending on requirements.

Using the DGS-6600 as an Aggregation Layer Switch 
Using a set of modules with 10/100/1000BASE-T ports, support for PoE, SFP, and 10-Gigabit trunk ports, IT staff can install a module with various types of ports in a free slot and use the device as an aggregation layer switch (i.e. e. Distribution), which provides high port density for connecting a large number of workplaces in the office or in Metro Ethernet networks with a high density of subscriber equipment.

High performance 
The switch uses a distributed switching method where each line module (a module with a port to connect directly to network nodes) defines a transmission path for each packet. Switches synchronize switching and routing information between control and line modules in order to determine the fastest path for data transmission. By using a line module that performs L2/3/4 switching independently of the control modules, the DGS-6600 series switches perform faster packet transmission without delay. 

High port density 
By installing expansion modules in a 4-slot chassis, users can get up to 144 Gigabit ports or 48 10-Gigabit ports, and in an 8-slot chassis, up to 288 Gigabit ports or 96 10-Gigabit ports. All modules can be hot-swapped without making changes to the hardware or software settings. The use of 96 non-blocking 10GE ports simplifies the transition to a 10G backbone.

Application Convergence
The DGS-6600 series switches combine advanced hardware and software features such as QoS and Multicast routing to enable real-time applications such as Internet telephony, video conferencing, and IP video surveillance. and IPTV. In addition, these switches support PoE, providing power and network connectivity for PoE devices such as IP phones and wireless access points. Switches are the ideal solution for large-scale enterprises. An example of application convergence is the use of mobile VoIP applications through wireless access points connected to DGS-6600 series switches.

Redundant AC and DC power supplies cannot be used together. Redundant DC power supplies do not support PoE functionality, i.e. PoE modules will work like normal modules.

Support for IPv6 technology
DGS-6600 series switches are fully compatible with IPv6 based networks. Net 

The Internet is constantly expanding due to an increase in the number of applications that use the Internet, including wireless devices, various equipment for home and office, Internet-connected vehicles, integrated telephony services, as well as in connection with the growing needs in computing and gaming. The use of IPv6 addressing simplifies the mechanisms used to provide end-to-end security for network devices. IPv6 support is especially relevant for applications and services that require a large number of IP addresses.

Comprehensive Security
Switches of the DGS-6600 series provide protection not only from unauthorized access of users, but also prevent penetration of viruses and "worms". Access protection is provided by ACLs, Port Security, and IP-MAC-Port Binding. Advanced security features provide protection against malicious attacks disguised as control protocols that can overload the central processing unit (CPU) and degrade performance. The DGS-6600 series enhances network management security by providing authentication and encryption of administration traffic using SSH v2 and SNMP v3 protocols.

MPLS Functions 
The DGS-6600 series switches support MPLS (Multiprotocol Label Switching) functions to enable next-generation intelligent networks and provide a wide range of advanced services within the existing infrastructure. Support for the MPLS function allows enterprise customers to use services such as point-to-point VPN, VPWS (VLL) and point-to-multi-point VPN, VPLS. This solution can be easily integrated into any existing infrastructure such as IP, Frame Relay, ATM or Ethernet. Subscriber traffic coming through different channels can be aggregated in the MPLS edge segment without changing the current settings of access switches, since MPLS does not depend on the technologies used at the access layer.

Traffic management for Triple Play services 
The DGS-6600 series provides a set of multilayer QoS/CoS features, including flow-based bandwidth control and broadcast/multicast/unicast storm protection, to ensure that delay-critical network services such as VoIP, video conferencing, IPTV, and IP video surveillance will be served with the appropriate priority. Bandwidth control provides guaranteed bandwidth for these services in case of high network load. With support for Layer 2 multicast, the DGS-6600 switch realizes the processing of IPTV applications.

D-Link Green technology 
D-Link is at the forefront of developing innovative energy-saving technology that does not compromise device performance or functionality. The DGS-6600 series switches support D-Link Green technology, which allows you to use the power saving mode, Smart Fan and PoE on a schedule. The Power Save feature provides automatic power down for inactive ports. The Smart Fan function automatically turns on the built-in fans at a certain temperature, ensuring long-term, reliable and environmentally friendly operation of the switch. Using PoE on a schedule allows the switch to receive information about the activity of a specific port at a given point in time, and, if necessary, automatically turn off an inactive port.
