900-12X AND 24X SERIES

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 load-

sharing 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.

Performance

The x900-24X is a powerful Layer 3+ switch

with a 168Gbps switching fabric, achieving wire-

speed switching and routing performance with a

forwarding rate of 71.4Mpps. It can support up

to two wire-speed 10GbE ports for high

performance, high capacity network applications.

The x900-12XT/S is a powerful Layer 3+ switch

with a 84Gbps switching fabric, achieving wire-

speed switching and routing performance with a

forwarding rate of 35.7Mpps. It supports a

10GbE port for high performance, high capacity

network applications.
