10 Gigabit Ethernet Smart Managed Switches

The D-Link DXS-1210 Series conveniently offers a range of 10-Gigabit copper and fiber port combinations to cost-effectively alleviate network congestion. Select models are equipped with SFP+ or SFP28 ports for 10G/25G expandable network designed for scalability and can auto-detect surveillance and voice data to ensure uninterrupted video footage and jitter-free VoIP calls.

Alleviate Network Congestion
Add 10‑Gigabit Ethernet connectivity with these affordable high-performance switches. Designed for deployment in small to medium-sized business (SMB) core networks and powerful enough for enterprise aggregation applications.

Convenient Layer 2 & Layer 3 Lite Configurability
The DXS-1210 Series can be deployed as a Layer 2 aggregation switch with features such as port mirroring, STP, and LACP. When implemented as a Layer 3 Lite core switch, IP interfaces, ARP, IPv6 ND, Default Routing, and Static Routing can be applied for efficient routing applications.

An Added Line of Defense Against Attacks
The DXS-1210 Series defends your network with D-Link’s innovative Safeguard Engine™ to neutralize threats such as malicious network flooding attacks, ARP spoofing, and bogus DHCP IP addressing. The DXS-1210 Series supports 802.1X port-based and host-based authentication, allowing the network to be authenticated through external RADIUS servers.

Unhindered Surveillance & VoIP with a Simple Click
If you need surveillance or VoIP, there is no need to build a dedicated network. With the DXS-1210 Series, expediting latency-intolerant services such as surveillance and VoIP through the existing network can’t be any easier. Simply enable the Auto Surveillance VLAN & Auto Voice VLAN features. Your surveillance videos will always run smoothly and your VoIP calls will be crystal-clear from beginning to end, even during peak working hours.

Better for Your Budget, Better for the Planet
When low-traffic or idle interface ports are detected, the DXS-1210 Series automatically transitions them into a low-power state, substantially reducing overall device power consumption. Furthermore, the DXS-1210 Series can determine the approximate length of cables attached to each port to apply just enough power for data transmission on that link, saving even more power while lowering total cost of ownership (TCO).
Juniper Networks EX3400 Ethernet Switch delivers a highperformance, flexible, and costeffective solution for today’s most demanding converged data, voice, and video enterprise access environments

To simplify network operations, the EX3400 is hardware-ready1 to act as a satellite device to support a Juniper Networks Junos Fusion Enterprise deployment, which can combine several wiring closets into one logical management platform. The EX3400 also supports Juniper Networks Virtual Chassis technology, allowing up to 10 switches to be interconnected over uplink ports and managed as a single device, delivering a scalable, pay-as-you-grow solution for expanding network environments.

The Juniper Networks® EX3400 Ethernet Switch with Juniper Networks Junos® Fusion Enterprise and Virtual Chassis technology provides enterprises with the flexibility and ease of management that previously was only available with higher-end access switches. The fixed-configuration EX3400 supports a number of key features, including:
- Junos Fusion Enterprise allows large numbers of EX3400 switches to be configured as satellite devices that connect to an EX9200 core aggregation switch to create a single logical device.
- 24-port and 48-port models with and without Power over Ethernet (PoE/PoE+) are for campus wiring closet deployments
- Data center-optimized cooling options offer both front-to-back and back-to-front airflows, making the EX3400 suitable for GbE data center access deployments.
- Two redundant, field-replaceable power supplies each provide up to 920 watts of power.
- 24-port data center models are included for metro deployments.
- Four dual-mode (GbE/10GbE) small form-factor pluggable transceiver (SFP/SFP+) uplink ports and two 40GbE QSFP+ ports are available.
- Uplink ports can be configured as Virtual Chassis interfaces and connected via standard 10GbE/40GbE optic interfaces (40GbE uplink ports are preconfigured by default as Virtual Chassis ports).
- Comprehensive Layer 2 functionality with RIP and static routing is provided.
- A compact, 13.8-inch deep 1 U form factor supports flexible deployment options.
- An easy-to-manage solution includes centralized software upgrades and a single management interface.
- Support is available for the same consistent modular Juniper Networks Junos operating system control plane feature implementation used by all other Juniper fixed-configuration Juniper Networks EX Series Ethernet Switches.
- Support Is provided for Layer 3 (OSPF v2, IGMP v1/v2/v3, PIM, VRRP, Q-in-Q, BFD, virtual router) via an enhanced feature license (optional license required).
- Support is available for IPv6 management, including neighbor discovery, stateless auto configuration, telnet, SSH, DNS, system log, NTP, ping, traceroute, ACL, CoS static routing, and RIPng.
- IPv6 routing features (OSPFv3, virtual router support for unicast, VRRPv6, PIM, MLDv1/v2) are supported via an enhanced feature license.
- Energy Efficient Ethernet (EEE) capability is provided.
EX2300 and EX2300-C Ethernet Switches deliver a compact, high-density, cost-effective solution for small network environments where space and power are at a premium. Featuring a small, 1U footprint, the EX2300 and EX2300-C are ideal for access-layer deployments in micro branches, retail and workgroup environments, and converged network access in larger networks.

The EX2300 offers 24 10/100/1000BASE-T ports in a single platform, while the EX2300-C offers 12 10/100/1000BASE-T ports. Both models are available with or without IEEE 802.3af Power over Ethernet (PoE) or 802.3at PoE+ for powering attached network devices. Optional front panel 10GbE uplink ports support connections to higher-layer devices.

Both models support Juniper’s unique Virtual Chassis technology, enabling up to four of the switches to be interconnected and managed as a single device. Both models can also act as satellite devices in a Juniper Junos Fusion Enterprise deployment, which combines large numbers of access switches into a logical management platform.
EX3400 Overview

EX3400 Ethernet Switches are a cost-effective solution for today’s most demanding converged data, voice, and video enterprise access networks. The compact, fixed-configuration 1U devices offer levels of performance and management previously available only with high-end access switches. Featuring models offering either 24 or 48 10/100/1000BASE-T ports, the EX3400 switches also support IEEE 802.3af Power over Ethernet (PoE) or 802.3at PoE+ for powering networked telephones, video cameras, wireless LAN access points, and other IP devices. Four front-panel dual-mode (GbE/10GbE) small form-factor pluggable transceiver (SFP/SFP+) uplink ports and two 40GbE quad SFP+ (QSFP+) ports are also available for connecting the switches to upstream devices. The EX3400 supports Juniper’s unique Virtual Chassis technology for interconnecting up to 10 switches that can be managed as a single device. The EX3400 can also be configured as a satellite device in a Junos Fusion Enterprise deployment, which aggregates large numbers of access switches into a logical management platform.

Innovative Switch Design

Innovative switch design reduces cost and complexity, while unified management and automation tools consolidate system monitoring.

Centralized Management

When deployed as satellite devices in a Junos Fusion Enterprise environment, large numbers of EX3400 switches can be managed from a single interface.

Eight QoS Queues

Eight QoS queues per switch port ensure proper prioritization of voice, video, and multiple levels of data traffic, with room to converge other networks, such as building automation and video security systems.

Virtual Chassis

With Virtual Chassis technology, multiple interconnected EX Series switches function as a single logical device, reducing operational expenses and simplifying management.

Carrier-Class Reliability

Based on a field-proven Juniper architecture and the Junos OS, EX Series switches deliver carrier-class reliability for every application.

High Port Densities and Wire-Speed Performance

High 1GbE and 10GbE port densities and wire-speed performance provide flexibility in creating network topologies.
