Industry-leading Features
The x900-48 offers performance, flexibility,
and reliability, packaged in a compact 1RU standard
rack mount chassis.The x900-48 is a highly featured
access solution that incorporates a new generation
switching core for wire-speed Layer 3 IPv4 and
IPv6 routing, exceptional Quality of Service (QoS)
features, and a robust hardware design with dual
hot-swappable power supplies.
Policy-Based Per-Flow Quality of
Service
Comprehensive, low latency QoS features
operating at wire-speed provide flow-based
traffic management with full classification,
prioritization, traffic shaping and min/max
bandwidth profiles.The x900-48 QoS features
are ideal for service providers who want 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 x900-48 QoS
features protect productivity by guaranteeing
the performance of business-critical applications
(including VoIP services), and help to restore
and maintain the responsiveness of enterprise
applications in the workplace.
Reliability
At 1RU high, with front-to-back cooling and
load-sharing power supplies, the x900-48 is
perfect for high-density rack environments
where conditions are demanding and space is
limited.The dual hot-swappable power supplies
(available in both 100/240VAC and -48VDC
PSU versions) eliminate the need for an
external redundant power supply and provide
reliability and redundancy for maximum service
uptime.
Flexible Uplinks
Four hot-swappable gigabit SFP uplink ports
can be aggregated to provide a total of 4Gbps
of uplink bandwidth, and can support any
combination of gigabit copper, or short haul
and long haul fiber SFP modules.This flexibility
of uplink interface options caters for multiple
applications and connectivity requirements.
Power to Perform
The x900-48 top-of-the-line, multilayer switch
is built to meet the needs of high performance
network services.Together with Allied Telesis'
advanced software feature set, AlliedWare, the
x900-48 is a superior access switching solution,
bringing true intelligence to the edge.
Fiber to the Home (FTTH)
With 48 100BASE-X SFP ports and four
gigabit SFP uplinks, best-in-class QoS, 50°C
operating temperature, and dual hot-
swappable AC or DC power supplies, the high-
density low-cost-per-port x900-48FS switch is
the perfect solution for FTTH. Advanced QoS
allows service providers to guarantee delivery
of Triple Play content, while the x900-48FS
high reliability guarantees maximum uptime,
whether in a central office or roadside cabinet.
The x900-48FS main ports support both single
BiDi 100BASE-BX and dual-fiber 100BASE-FX
hot-swappable SFPs, and the four uplink ports
support gigabit fiber or copper SFPs.
Fiber to the Desk (FTTD)
Secure connections to the desktop are only
guaranteed by using fiber. The x900-48FS is
the ideal solution for FTTD, satisfying the
security and budget requirements demanded
by government agencies. With 48 100BASE-X
SFP ports and four gigabit SFP uplinks, front-
to-back cooling, and dual hot-swappable AC or
DC power supplies, the x900-48FS switch
delivers high reliability and low-cost-per-port.
Stress tested
All Allied Telesis products are strenuously
tested using Highly Accelerated Life Test
(HALT) and Highly Accelerated Stress
Screening (HASS) procedures. Under the
Allied Telesis HALT regimen, products are
tested well past specified tolerance limits for
heat, cold, vibration, shocks, and drops, to
ensure that they are more than robust enough
for real-world conditions.
