SwitchBlade x908
ADVANCED LAYER 3 MODULAR COMPACT SWITCH
The SwitchBlade x908 8-slot
industry-leading modular
compact switch is the ideal
solution for the small to
medium modern enterprise
network core where reliability,
resiliency and high performance
are the key requirements.
Small Physical Size
The SwitchBlade x908 packs a remarkable
amount of networking performance into
a small, 3RU-high box. Taking up no more
rack space than three simple “pizza box”
switches, the SwitchBlade x908 provides
users with unrivaled reliability and exibility.
High Availability
The SwitchBlade x908 was designed with
reliability in mind. With dual power supplies,
fan modules and a comprehensive range
of expansion modules (XEMs)—all hot-
swappable—the network can be maintained
and recongured when necessary without
affecting uptime.
Active-Active Architecture
The Active-Active architecture allows
two SwitchBlade x908 chassis to be inter-
connected via a passive 160Gbps rear panel
connector, allowing the two switches to
communicate. This architecture ensures
that edge devices, which are connected
to both switches, can continue to operate
even in the event of a single SwitchBlade
x908 failure. This architecture, unlike
some competitive Active-Redundant
architectures, ensures users achieve the full
100% utilization of their purchased network
components for the maximum time, thus
decreasing Total Cost of Ownership (TCO).
Ethernet Protection Switching Rings
The use of the SwitchBlade x908 in
conjunction with other EPSRing-enabled
devices provides a 10Gbps high-bandwidth
resilient ring backbone capable
of providing sub 50ms failover.
This architecture is perfect
for the backbone core of any
Enterprise or Service Provider
network, as it allows nearly hit-free
networking to be accomplished, and is
suitable for the delivery of voice, video and
data.

Scalable
The SwitchBlade x908 supports up to eight
XEM expansion modules, allowing the
user to change the conguration of their
network as needed. Each SwitchBlade x908
can support up to 96 Gigabit ports or up to
16 10GbE ports, while stacking two chassis
to build a resilient core that doubles the
number of ports.
Enterprise Applications
The SwitchBlade x908 is the ideal Enterprise
switch for small- to medium-sized network
installations, but is also at home in larger
distributed campus-type networks, when
individual switches are connected using
EPSRing technology.
NSP Applications
The SwitchBlade x908
has been certied by the
Metro Ethernet Forum
(MEF) Certication program,
which tests products
for conformance to the
strict requirements of Carrier Ethernet.
Compliance with this certication makes
the deployment of this chassis a much easier
option for Network Service Providers.
Extended Mode
SwitchBlade x908 chassis running selected
XEM expansion modules can be congured
to use larger hardware table sizes and more
Link Aggregation Groups (LAGs). This
makes the SwitchBlade x908 more suitable
for applications in the core or in distribution
layers of larger networks.
