SWITCHBLADE

Layer 3 Modular Switch

AT -SB4004

4 line card capacity

Up to 96 Gb ports

AT -SB4008

8 line card capacity

Up to 192 Gb ports

Designed to meet the most demanding

performance requirements of enterprise class

networks, the SwitchBlade

4000 Series Layer 3

modular switches are ideally suited to network

aggregation and server connectivity. Packaged

in four or eight slot modular chassis

configurations, the SwitchBlade

4000 Series

blends state-of-the-art Layer 3 functionality with

industry leading value. Redundancy and

resiliency features including hot-swappable

Power Supply Units (PSUs), fan trays, line cards

and redundant controllers ensure high system

availability.The switching architecture delivers

wire-speed switching and IP/IPX routing with

advanced, flexible policy-based quality of service

and rich multicast support. Multiple user

interface options provide a set of configuration

and control features that facilitate effortless

manageability while allowing maximum flexibility

and control of the network.

Eliminate network bottlenecks and

boost network performance

AT-SB4000 Series offers uncompromised packet

switching performance, delivering Layer 2 and

Layer 3 IP/IPX data at wire-speed on all ports

regardless of packet size. With a switch capacity

of up to 384 Gbps yielding 286 Mpps of

throughput, the AT-SB4000 Series seamlessly

meets the demands of education, government,

and enterprise networks.

Secure your company

The AT-SB4000 Series offers many advanced

features to ensure company security: Wire-

speed Filtering, MAC control, Port-Intrusion

Allied Telesis

4000

Detection, Access Control Lists, Port Security,

Secure Shell (SSH) and Secure Socket Layer

(SSL). With 4096 VLANs available, which are

Port, Protocol, Subnet, and MAC Address based,

security across VLANs is assured.The security

features (MAC & IP addresses, SYN, ACK bit

level) are in the hardware.

Minimize the cost of downtime

The SwitchBlade

controllers, power supplies, and line cards

ensure that this core network device keeps

networks alive 24/7.

With N+1 power supply redundancy downtime

is completely eliminated. Cooling is assured with

up to 11 cubic meters / minute of airflow for the

four fan AT-SB4004, and up to 19 cubic meters /

minute of airflow for the six fan AT-SB4008.

Hot-swappable switch controllers provide

redundancy and, when two switch controllers are

installed, sharing of load for increased performance.

Port trunking is provided to assure very reliable

high-speed connections. Combining multiple

physical connections in a single logical connection

provides both greater bandwidth and redundancy .

Virtual Router Redundancy Protocol (VRRP)

provides automatic router backup in

mission-critical environments.This feature enables

multiple AT-SB4000 Series switches to share a

virtual IP address, used as the default LAN

gateway. Should the master fail, the virtual IP

address is seamlessly assumed by the other

switches.This results in a down-time of only

three seconds. Meanwhile, LAN devices can

continue to be configured (for example with

DHCP) with a single default gateway address.

Rapid Spanning Tree Protocol (RSTP) prevents

loops in Layer 2 networks and also provides rapid

system recovery following a failure in the network.
