Quality of Service

The AT-SB4000 Series market leading Quality of

Service (QoS) mechanism allows traffic shaping in

a highly programmable manner, based on Layer 2

to Layer 4+ packet characteristics.

The resulting 128 different Classes of Traffic

enable flexible policy enforcement with

independent latency and 64kbps increment

min/max bandwidth guarantees. AT-SB4000

Series units use IEEE 802.1p, DiffServ, Layer 4

filtering and RSVP along with sophisticated

hardware based switching to deliver a rich QoS

capability.The AT-SB4000 Series fits into

education and government networks requiring

separation of multicast traffic and dual staff and

student networks all running over a single

infrastructure. It is also scalable with a large

number of traffic classes with varying

requirements as is typical in today's converged

application-based networks.

Multimedia capable multicasting

With multicast protocols such as IGMP, IGMP

Snooping, DVMRP, PIM-SM, and PIM-DM, the

AT-SB4000 Series delivers TV cable

broadcasting, video conferencing, phone-

conferences, phone, and web-browsing

capabilities. Multicasting between VLANs at

wire-speed is also offered for streaming server

application with clients on different VLANs.

Broadcast storm control

A traffic storm occurs when packets flood the

network, creating excessive traffic and degrading

network performance.The broadcast storm control

(BCSC) feature allows the user to set limits for each

VLAN.This is useful to prevent traffic congestion of

the network and inefficient usage of the core.

World class software

The AT-SB4000 Series includes AlliedWare

software, allowing simple configuration and control

without compromising flexibility.The switches have

built-in DHCP server;TFTP for image and

configuration downloads; Network Time Protocol

client and server capabilities; advanced,

customizable triggers with an e-mail client allowing

unmatched flexibility in monitoring and controlling

events; standard CLI and highly intuitive GUI device

configuration tools plus full SNMP and MIB

support for network management - accessed

either in-band or out-of-band via serial console or

10/100Base-T port.The AT-SB4000 Series leads

the market with an extensive suite of Layer 2 and

Layer 3 features, including static routing, routing

protocols (RIP/RIPv2, OSPF), multicast protocols

(IGMP , IGMP Snooping, DVMRP , PIM-SM, PIM-DM),

IP , IPX, 4096 VLANs, and flexible port trunking with

link aggregation.These features are bundled to suit

the needs of a standard application or for an

advanced architecture.

AlliedWare

A common OS ensures the AT-SB4000 Series

Switch will interoperate seamlessly with other

Allied Telesis fixed function, modular routers and

all Layer 3 to Layer 7 switch families, allowing

operational investment protection for training,

management and monitoring.

A standards-based implementation assures full

interoperability with all other major network

equipment vendors. The AT-SB4000 Series Switch

is shipped "ready to run" with AlliedWare

comprehensive software suite that includes all the

features, management capabilities and

performance today's networks demand.

AlliedView - EMS

AlliedView-EMS is a Java-based device

management solution from Allied Telesis that

provides a user-friendly, window-based

environment to manage the AT-SB4000 Series

Switch, as well as the complete lineup of Allied

Telesis managed devices. Whether managing a

large network distributed across multiple sites or

a small network with only a handful of nodes,

AlliedView-EMS provides the tools needed to

effectively monitor and proactively manage

Allied Telesis's intelligent networking products.

Triggered Events

A trigger sets off an ordered sequence of

scripts and commands to be executed when a

certain event occurs, providing a powerful

mechanism for automating the response to

specific events. Each trigger may reference

multiple scripts and any script can be used by

any trigger. Using this feature, the AT-SB4000

Series Switch can, for example, send an email

alert to the network manager when trouble

occurs, or it can automatically shut down an

interface to protect against suspected attacks.

Scripts

The scripting facility enables sequences of

commands to be stored in a script and replayed

at any time, allowing the AT-SB4000 Series Switch

to be easily configured or quickly re-configured.

This is useful when developing a complex

configuration, making the same configuration

change to several different Switches, or

introducing a configuration change that must

occur at a particular time. Scripts can be created

on a PC and uploaded to the AT-SB4000 Series

Switch, or they can be created using the

AT-SB4000 Series Switch's own integrated text

editor.They can be activated either from the

command line or from a trigger.

ports of 10/100Base-TX (RJ45), 256 ports of

100Base-FX, 192 ports of 10/100/1000Base-T,

192 ports of 1000Base-X or combinations, the

AT-SB4008 provides great porting flexibility.

The AT-SB4004 and its 4 Line Card slots

support up to 192 ports of 10/100Base-TX

(RJ45), 128 ports of 100Base-FX, 96 ports of

10/100/1000Base-T, 96 ports of 1000Base-X

or combinations.

Cable management at the core of the network

is often a major challenge.The AT-SB4008

Switch offers a detachable cable manager to

help tame the cabling jungle.

Power Supply Units

Each AC power supply is rated at a maximum

of 420W with a worst-case efficiency of 65%,

which equates to 3A at 230V (or 6A at 110V)

on the mains input per power supply. Worst

case AC PSU output load regulation is +/- 0.5%.

The inrush current under cold start at 230V is

75A and at 110V is 37A. AC PSU MTBF is

unpackaged, or 4.3kg (9.5 lbs) packaged.

Each DC power supply is rated at a maximum

of 420W with a worst-case efficiency of 65%,

which equates to 11A at 59Vdc (or 18A at

36Vdc) per power supply on the input side.

Worst case DC PSU output load regulation is

+/- 0.5%.The inrush current under cold start at

72V is 50A and at 36V is 25A. DC PSU MTBF

is 84,160 hrs and weighs 3.6kg (7.9 lbs)
