DELL EMC POWERSWITCH S4048TON SWITCH

Energy-ecient 10GBASE-T top-of-rack switch optimized for data center eciency

The Dell EMC PowerSwitch S4048T-ON switch isthe industry’s
latest data center networking solution,empowering organizations
to deploy modern workloads and applications designed for the open
networking era.

Businesses who have made the transition away frommonolithic
proprietary mainframe systems to industry standard server platforms
can now enjoy even greaterbenets from Dell Technologies’ open
networking platforms. Byusing industry-leading hardware and
a choice of leading network operating systems to simplify data
centerfabric orchestration and automation, organizations cantailor
their network to their unique requirements andaccelerate innovation.

These new oerings provide the needed exibility to transform data
centers. High-capacity network fabrics are cost-eective and easy to
deploy, providing a clear path to the software-dened data center of
the future with no vendor lock-in.The S4048T-ON supports the open
source Open Network Install Environment (ONIE) for zero-touch
installation of alternate network operating systems, including feature
rich Dell EMC Networking OS9 and Dell EMC SmartFabric OS10.

High density 1/10G BASE-T switch

The Dell EMC PowerSwitch S-Series S4048T-ON is ahigh-density
100M/1G/10G/40GbE top-of-rack (ToR)switch purpose-built
for applications in high-performancedata center and computing
environments. Leveraginga non-blocking switching architecture, the
S4048T-ONdelivers line-rate L2 and L3 forwarding capacity within
aconservative power budget. The compact S4048T-ONdesign
provides industry-leading density of 48 dual-speed 1/10G BASE-T
(RJ45) ports, as well as six 40GbE QSFP+up-links to conserve
valuable rack space and simplify themigration to 40Gbps in the
data center core. Each 40GbE QSFP+ up-link can also support four
10GbE (SFP+)ports with a breakout cable. In addition, the S4048T­ONincorporates multiple architectural features that optimize
data center network exibility, eciency and availability,including I/O
panel to PSU airow or PSU to I/O panelairow for hot/cold aisle
environments, and redundant, hot-swappable power supplies and
fans. S4048T-ON supportsfeature-rich Dell EMC Networking OS9
and Dell EMC SmartFabric OS10, VLT, network virtualizationfeatures
such as VRF-lite, VXLAN Gateway and support for Dell Embedded
Open Automation Framework.

• The S4048T-ON is the only switch in the industry that supports
traditional network-centric virtualization (VRF) and hypervisor
centric virtualization (VXLAN). The switch fully supports L2
VXLAN gateway function and has hardware support for L3
VXLAN routing.

• The S4048T-ON also supports Dell Technologies’ Embedded
Open Automation Framework, which provides enhanced network
automation and virtualization capabilities for virtual data center
environments.

• The Open Automation Framework comprises a suite of
interrelated network management tools that can be used
together or independently to provide a network that is exible,
available and manageable while helping to reduce operational
expenses.
