Layer 3 Switch Base Unit Chassis with Back Plate and 2 Empty Slots for CPU modules and 8 Empty Slots for line cards

D-Link’s DES-7200 series of chassis-based switches are intelligent and high-performance multi-layer LAN devices designed for enterprise campus and metropolitan area networks (MAN). They are ideal for deployment in environments where uninterrupted running of network applications and a high level of performance, security and control are required.

Featuring a fexible modular architecture and industry standard compliance, these switches provide scalable expansion and a high level of investment protection for businesses and telecom carriers to deploy Gigabit and 10-Gigabit packet switching and routing for offce networking and Ethernet-based Internet services to the homes.

The DES-7200 series switches feature minimum or zero network downtime, robust security and real-time running of bandwidth-intensive applications. Equipped with high-speed switch fabrics, redundant backup/load sharing capability and advanced software functions including complete IPv6 support, these switches provide the performance, high availability and future-proof architecture suitable for applications of not just today but well into the future.

Two DES-7200 series offers end-to-end connectivity and granular application control with two chasses supporting a wide range of port modules:

DES-7210 10-slot chassis with:
- 2 slots for dual control modules with dual load-sharing/redundant switch fabric of up to 384Gbps
- 8 slots for user-selectable port modules
- 2 slots for redundant backup power supplies
- 1 slot for fan module
- Up to 384Gbps switch fabric
- 1.6Tbps backplane capacity
- 286Mpps packet forwarding rate
- Up to 384 Gigabit ports
- Up to 32 10-Gigabit ports

Flexible Modular Design
The DES-7200 series is available in two models: the DES-7206 6-slot chassis with 4 open slots, and the DES-7210 10-slot chassis with 8 open slots. The open slots can be ftted with user-selectable port modules. In addition to the open slots, 2 slots are reserved for redundant backup control modules, 2 slots for redundant backup power supplies, and slots for replaceable fan modules. This modular architecture allows modules to be gradually added to meet network rowth, and modules to be easily swapped anytime to ft network requirement change.

Deployable as Core or Distribution Switch
Using a common set of modules for 10/100/1000BASE-T ports, PoE support, SFP and 10-Gigabit uplinks, IT personnel can ft a DES-7200 switch with different port types and deploy it either as a core switch or an aggregation (i.e. distribution) switch. A DES-7200 core switch provides numerous high-speed fber backbones for a campus and central offce network, while a DES-7200 aggregation switch can provide high port density connections to workstations in an offce environment, or to subscribers’ CPE in a densely populated Ethernet metro area network.

High Availability
Both the DES-7206 and the DES-7210 provides 2 slots for installation of control modules. Each control module is equipped with its own switch fabric hardware and management agent, and can be used for redundant backup and sharing of network traffc load and management tasks. Adding to this feature are 2 redundant backup power supplies and hot swappable fan module to create very highly available chassis-based devices suitable for mission-critical network applications.

High Performance
The DES-7206 6-slot switch provides a backplane capacity of 0.8Tbps, a switch capacity of up to 192Gbps and a system performance of up to 142Mpps. The DES-7210 10-slot switch provides a backplane capacity of 1.6Tbps, a switch capacity of up to 384Gbps and system performance of up to 286Mpps. To make use of this high-performance hardware, these switches utilize a distribution switching method which has each line card (the port module that directly connects to the network nodes) intelligently determine the switch path for each data packet. The switches synchronize the switching and routing information between the control cards and the line cards to map out the fastest data transfer path. With each line card capable of performing L2/3/4 on-board packet switching without relying on the control cards, the DES-7200 switches can deliver very fast packet forwarding at almost zero-wait speed.

High Port Densities
Port densities can reach 192 Gigabit or 16 10-Gigabit ports per 6-slot chassis, or 384 Gigabit or 32 10-Gigabit ports per 10-slot chassis. All port modules are hot-swappable, and can be used for in either chassis type without the need to change any hardware or software settings.

Application Convergence
The DES-7200 combines high-speed hardware with software functions like prioritized traffc QoS and multicast routing to deliver the performance suitable for real-time applications such as Internet phone, streaming multimedia and TV. In addition, these switches offer Power over Ethernet (PoE) solutions to provide both electrical power and network connectivity to PoE-capable devices, such as IP phones and wireless AP, and are ideal for large-scale enterprise edge deployment. An example of this application convergence would be VoIP for mobile users via wireless access points connected through
the DES-7200 switches.

Complete IPv6 Support
The DES-7200 provides complete support for IPv6 to accommodate the potential huge increase in number of users and geographical needs of the Internet expansion. It addresses the requirements of emerging applications such as Internet-enabled wireless devices, home and industrial appliances, Internet-connected transportations, integrated telephony services, sensors networks, and distributed computing or gaming. The use of globally unique IPv6 addresses simplifes the mechanisms used for reach-ability and end-to-end security for network devices, functionality that is crucial to the applications and services that are driving the demand for IP addresses.

Enterprise-Wide Security
The DES-7200 provides not only network access security but also protection against virus and worm attacks. Access security is provided through comprehensive policy-based ACL, port security, IP-MAC-Port binding features and Defeat IP Scan, while attacks hidden behind control protocols are thwarted to prevent the switch’s CPU from being overwhelmed with unnecessary tasks which can cause degradation to a network’s performance. The DES-7200 extends security to network management via such functions as SSH v2 and SNMP v3 with authentication and encryption of management traffc.

MPLS Functions
With the use of Advanced Service Engine (ASE), the DES-7200 supports many advanced Multi-protocol Label Switching (MPLS) functions, including MPLS label management, LDP, MPLS L2/L3 VPN and VPLS, enabling enterprises and service providers to build next-generation intelligent networks that deliver a wide variety of advanced, value-added services over a single infrastructure. This solution can be integrated seamlessly over any existing infrastructure, such as IP, Frame Relay, ATM, or Ethernet. Subscribers with differing access links can be aggregated on an MPLS edge without changing their current environments, as MPLS is independent of access technologies.

NAT Traversal and Accounting
The DES-7200 provides Layer 3 IP packet routing with Network Address Translation (NAT) useful for enterprise networks as well as Internet providers offering Ethernet metro area network services. With dynamic IP address generation for users in a campus LAN and subscriber CPEs in a carrier network, the DES-7200 can be deployed for end-to-end services without incurring the cost of attaching external routers to packet switching devices. In addition, the DES-7200 provides 802.1X access control with period accounting, multiple accounting and statistics, bandwidth restriction and RADIUS server support,
enabling carriers to implement complete Ethernet-based Internet services to home customers.

QoS & Bandwidth Management
The DES-7200 supports numerous advanced traffc management options including fow-based bandwidth control and broadcast/multicast storm control. It provides egress traffc bandwidth control with minimum granularity of 64Kbits. Combining Rate Limiting applicable to categories of subscriber CPE and access control-based accounting, the DES-7200 provides the functions useful for carriers offering services to home users in a metropolitan Ethernet network.

Comprehensive Management
To maximize management uptime, the DES-7200 provides optional dual redundant backup management agents in the same chassis. It offers a comprehensive set of management features to provide enterprise-wide visibility and control to network administrators for confguration, access/traffc monitoring and troubleshooting. These features are accessible through a CLI, Telnet or SNMP console. RMON monitoring is supported, and complete debug, system information, alert information and interface management are provided.
