High-performance switch delivering wire-speed 10-Gigabit switching, routing, and ultra-low latency.

  • 20 x SFP+ ports
  • 4 x 10GBASE-T/SFP+ Combo ports
  • Physical stacking with up to 4 devices per stack
  • Layer 2+ static routing / RIPv1/v2/ng
  • Optional Layer 3 dynamic routing / OSPF
  • Data Center Bridging (DCB) features
  • Hot-swappable power supplies and fan module

High Availability and Flexibility

The DXS-3400 Series switches feature a modular fan and power supply design for a high availability architecture. The hot-swappable design means that fans and power supplies can be replaced without affecting switch operation. Physical and virtual switch stacking allow the switches to be managed from a single IP address and provide redundancy for connected devices. The Switch Resource Management (SRM) feature allows the hardware table size to be changed, so that switch functions can be optimized based on the use of the switch.

Flexible Management With Multiple Software Images

The DXS-3400 Series is designed for use with two different software images: the Standard Image (SI) and the Enhanced Image (EI). The Standard Image provides core SMB and SME functionality. The Enhanced Image supports all Standard Image features, in addition to advanced L3 routing for enterprise integration. With multiple software images, only the required features need to be purchased, providing a flexible approach to software licensing

Lossless Ethernet

Data Center Bridging (DCB) is an essential set of enhancements to Ethernet for networking in data center environments. The DXS-3400 Series switches support several core components of Data Center Bridging (DCB) such as IEEE 802.1Qbb Priority-based Flow Control, IEEE 802.1Qaz Enhanced Transmission Selection, and IEEE 802.1Qau Congestion Notification.


The DXS-3400 Series switches feature front-to-back airflow which facilitates the building of energy-efficient data centers. The front-to-back airflow optimizes air circulation inside the rack, allowing hot and cold isles in data centers, increasing energy efficiency in comparison to a mix of front-to back and side-to-side airflow. The switches also feature in-built smart fans; internal heat sensors monitor and detect temperature changes and react accordingly by utilizing different fan speeds for different temperatures.
