900-24X SERIES 
| Advanced Gigabit Layer 3+ Expandable Switch
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 1RU rack
mount chassis, provide the ultimate in space
saving, reliability and resiliency.These features,
combined with front-to-back cooling, make the
x900-24X 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 x900-24X
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
x900-24X 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 150Gbps 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.
