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.
