Allied Telesis AT-FAN06 Manuale Utente

Switches

Designed for virtualized data center and cloud environments, the Allied Telesis AT-DC2552XS 
switch provides high density 10GbE and 40GbE connectivity, making it ideal for today’s mini and 
small data centers, which use up to hundreds of server ports.

The Allied Telesis AT-DC2552XS is a 48 

x 10GbE (SFP+) port high-bandwidth 
and high-density switch designed for 
data center applications. It also provides 
four QSFP+ 40GbE slots for “fat-pipe” 

high bandwidth uplinks. This switch 
delivers 1280Gbps of switching fabric 
with ultra low sub-μsec latency. Airflow 
has been optimized for front-to-back 
cooling for data center environments. 

The unit can also accommodate a 1+1 

resilient power supply, along with these 
specifications, in a very compact 1RU 
unit chassis.

A smarter data center can be achieved 

by connecting servers and storage 
facilities with a high-speed and low 
latency network fabric that is faster, 

greener, open, and easy to manage.

Energy efficient architecture and 
front-to-back air-flow cooling of the 

AT-DC2552XS are critical factors in 

optimizing data center economics—as 
companies must balance performance 
with power consumption to meet 
energy budgets.

As bandwidth-intensive applications—

such as Web 2.0, virtualization, High-
Performance Computing (HPC) and 
Network Attached Storage (NAS)—
continue to proliferate within enterprise 
data centers, 10 Gigabit Ethernet 

(10GbE) provides a cost-effective way 

to increase throughput and seamlessly 
deliver customer Service Level 

Agreements.

10GbE empowers companies to

expand application capabilities, reduce 
time to solve complex financial and 
scientific applications, and quickly 
respond to changing customer needs 
and market conditions.

In combination with the AT-VNC10S 
Network Interface Cards for servers, it 
helps clients to reduce the use of I/O 
adapters, reducing costs and complexity.

The AT-DC2552XS has two slots for 

hot-swappable PSUs (Power Supply 
Unit) and fans.  In addition, SFP+ and 

QSFP modules can be easily removed 

and replaced with no interruption to the 
network. These hot-swappable modules 
guarantee the continued delivery of 
essential services. 

Cut-through switching sends packets 

to their destination as soon as the 

first part is ready. The delay is minimal 

and the packet reaches its destination 
in the shortest possible time. With 
cut-through mode, the AT-DC2552XS 
forwards packets with a latency of 

505 nanoseconds with 40Gb / 800 

nanoseconds with 10Gb and is ideal for 
inter-server communication.

Cooling air flow has become a major 

design concern in modern data centers. 

The AT-DC2552XS utilizes front (PSU 

and fan side) to back (ports side) airflow, 
which is suitable for rack mounting in 
data centers.

In keeping with our commitment to 
environmentally 
friendly products, this 
switch is designed 
to reduce power consumption and 
minimize hazardous waste.
