D-Link’s DXS-3400 Series Top-of-Rack 10 Gigabit Stackable Managed Switches consists of new
compact, high-performance switches that feature wire speed 10-Gigabit Ethernet switching,
routing, and ultra-low latency. The 1U height and high port density make the DXS-3400 Series
suitable for enterprise and campus environments where space is at a premium. The
DXS-3400 Series switches includes 20 x 10GBASE-T or 20 x 10G SFP+ ports and 4 10GBASE-T/
SFP+ combo ports, making them suitable for data centre, core, and distribution applications.
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 aecting 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 optimised based on the use of the switch. The
DXS-3400 Series switches come with 3 modes; IP Mode, LAN Mode and L2 VPN Mode, which
modify the size of the Layer 2 and 3 tables for optimum eciency.
Feature Rich Software
The DXS-3400 Series switches include feature rich software which satises the needs of
Small Medium Business, Small Medium Enterprise, and campus users. It supports a wide
range of Layer 2 and 3 functions such as VLANs, inter-VLAN routing, multicasting, Quality of
Service (QoS), Virtual Router Redundancy Protocol (VRRP), Routing Information Protocol (RIP)
v1/2, Next Generation RIP (RIPng), Policy-Based Routing (PBR), and security features. The
DXS-3400 Series also includes an easy-to-use web interface and an industry standard CLI for
improved management.

Lossless Ethernet
Data Center Bridging (DCB) is an essential set of enhancements to Ethernet
for networking in data centre environments. The DXS-3400 Series switches
support several core components of Data Center Bridging (DCB) such as IEEE
802.1Qbb, IEEE 802.1Qaz, and IEEE 802.1Qau. IEEE 802.1Qbb (Priority-based
Flow Control) provides ow control on specic priority to ensure there is no
data loss during network congestion. IEEE 802.1Qaz (Enhanced Transmission
Selection) manages the allocation of bandwidth amongst dierent trac
classes. IEEE 802.1Qau (Congestion Notication) provides congestion
management for data ows within network domains to avoid congestion.
Energy Ecient
The DXS-3400 Series switches feature front-to-back airow which facilitates
the building of energy-ecient data centres. The front-to-back airow
optimises air circulation inside the rack, allowing hot and cold isles in data
centres, increasing energy eciency in comparison to a mix of front-to-
back and side-to-side airow. The switches also feature in-built smart fans;
internal heat sensors monitor and detect temperature changes, and react
accordingly by utilising dierent fan speeds for dierent temperatures.
At lower temperatures, the fans will run more slowly, reducing the switch’s
power consumption and noise.
DXS-3400 Series
