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)

• Two-rate three-color (green, yellow, red)
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
• RADIUS Authentication
