SwitchBlade

Advanced Layer 3 Modular Switch

The Allied Telesis SwitchBlade

x908 industry

leading modular switch incorporates eight high-

speed 60Gbps expansion bays, delivering a new

generation of high performance. The SwitchBlade

x908 provides scalable and versatile switching

solutions for today's Enterprise networks.

The highly configurable SwitchBlade x908 3RU

modular switch combines an advanced IPv4 L3

feature set and comprehensive IPv6 routing

features, with wire-speed IPv6 hardware capability,

future proofing the network.

Featuring dual hot-swap PSUs, an advanced QoS

feature set, multicasting support, and LAN resiliency

support, the SwitchBlade x908 also provides

Service Provider capabilities such as a large L3

route table, and EPSR support.

Stacking between two units is supported via fixed

stacking connectors on the rear of the chassis,

providing 160Gbps of stacking bandwidth. Stacking

of more than two units is via expansion modules

(XEMs) on the front panel.

The SwitchBlade x908 incorporates the

AlliedWare Plus™ Operating System, using an

industry standard Command Line Interface (CLI),

facilitating effortless manageability.

Expansion module options:

• AT-XEM-STK Stacking XEM

• AT-XEM-1XP 1 x 10GbE (XFP)

• AT-XEM-12S 12 x 100/1000BASE-X SFP ports

• AT-XEM-12T 12 x 10/100/1000BASE-T

(RJ-45) ports

• Future modules to include 12 x GbE with PoE

and 2 x 10GbE

Port Density:

• 96 x GbE ports per switch (with PoE

• 8 x 10GbE ports (16 with XEM-2XP)

per switch

•1344 x GbE ports per rack (14 units)

•112 x10GbE ports per rack (224 with XEM-2XP)

bandwidth metering, with burst sizes for

improved TCP-IP bandwidth limiting

performance and bandwidth resolution

down to 1Kbps

• Low switching latency essential for Voice

over IP (VoIP) and real-time streaming media

applications

Management

• Out of band 10/100/1000 Ethernet

management port and console management

port, both on the front panel for ease of

access

• An SD memory card socket on the front

panel, allowing software release files,

configurations and other files to be stored for

backup and distribution to other switches

• Port mirroring

• SSH and SNMPv3 for secure management
