Industry Leading Features

The AT-9900 series delivers performance,

flexibility, and reliability. Packaged in a 1RU

standard rack mount chassis, all AT-9900 switches

incorporate a switching core that yields wire-

speed Layer 3 IPv4 routing, exceptional Quality of

Service (QoS) features, and a robust hardware

design with dual hot-swappable power supplies.

Policy-based Quality of Service

Comprehensive, low latency QoS features

operating at wire-speed provide flow-based

traffic management with full classification,

prioritization, traffic shaping and min/max

bandwidth profiles. The AT-9924 QoS features

are ideal for service providers wanting to ensure

maximum availability of premium voice, video

and data services, and at the same time manage

customer service level agreements (SLAs). For

enterprise customers, the AT-9924 QoS features

protect productivity by guaranteeing

performance of business-critical applications

including VoIP services, and help restore and

maintain responsiveness of enterprise

applications in the networked workplace.

EPSR

Ethernet Protection Switched Rings prevents

loops in ring-based Ethernet networks. EPSR

provides high availability for mission critical

traffic, preventing loss of video, voice, or data

packets in the event of device failure.

Management Stacking

Stacking provides CLI-based management of up

to nine switches with the same effort as for one

switch.The Allied Telesis solution uses open

standards interfaces as stacking links so that

many switches can be stacked across different

sites, which is not possible using the proprietary

stacking cable solutions. Also, the use of open

standards interfaces avoids the use of expensive

specialized hardware with limited topologies.

Reliability

Dual internal hot-swappable load-sharing power

supplies provide ultimate space-saving reliability and

redundancy for maximum service uptime. Both

110/240V AC and 48V DC PSU versions are

available. There is no requirement for an external

RPS, and combined with front-to-back cooling and

a 1RU height, the AT-9924 is perfect for the high-

density rack environment where conditions are

demanding and space is at a premium.

Power to Perform

The AT-9924 top-of-the-line multilayer switch is

part of a series built to meet the needs of high

performance network services. Together with

Allied Telesis' advanced software feature set,

AlliedWare, the AT-9924 is a superior high-

density gigabit switching solution, bringing true

intelligence to the network.
