Unmatched Flexibility
The x900 Layer 3+ switches have high-speed
60Gbps expansion bays which provide a high level
of port flexibility and application versatility
unmatched by any other 1RU Gigabit Ethernet
switch on the market.The expansion modules can
be used in a variety of configurations to provide
tailored solutions that meet wide-ranging physical
networking requirements.
10GbE expansion modules and hot-swappable
XFPs provide high-speed, high-capacity fiber
uplinks, with the option of either 10Gbps or
20Gbps uplink capacity to the network core.
Resiliency can be achieved by using 10GbE
modules and MSTP (802.1s) for fast failover on link
failure.This is suitable for wiring closet aggregation
of gigabit to the desktop links and aggregating
gigabit uplinks from other network switches.
Ethernet Protected Switched Rings (EPSR) and
10 GbE modules allow several x900-24X
switches to form a protected ring with sub
50ms failover. This feature is perfect for high
performance at the core of enterprise or
provider access networks.

X900-12X AND 24X SERIES
| Advanced Gigabit Layer 3+ Expandable Switches
Combined with one or two 12-port
10/100/1000BASE-T (RJ-45) copper expansion
modules, the x900 is ideal for gigabit to the
desktop or gigabit aggregation applications.The
12 x 100/1000BASE-X (SFP) expansion
modules offer variable port options, designed
for aggregating mixed copper and fiber links in
server farms and data center applications.
x900 Layer 3+ switches provide maximum
Gigabit Ethernet port density in a compact
1RU chassis.Their high degree of flexibility
future-proofs your investment against changes
in network infrastructure, topologies, and
physical link requirements.
Reliability
Dual hot-swappable AC or -48V DC loadsharing power supplies packaged in the
x900-24X 1RU rack mount chassis, provide the
ultimate in space saving, reliability and resiliency.
These features, combined with front-to-back
cooling, make the x900 series perfect for the
high-density rack environment where space is at
a premium.
Policy-Based Quality of Service
Comprehensive, low latency Quality of Service
(QoS) features operating at wire-speed provide
flow-based traffic management with full
classification, prioritization, traffic shaping and
min/max bandwidth profiles.The x900 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. For enterprise customers, the x900
QoS features protect productivity by
guaranteeing performance of business-critical
applications (including VoIP services), and help
to restore and maintain responsiveness of
enterprise applications in the workplace.
