The product’s proven design leverages a sophisticated
chipset from the Industry’s leading supplier, featuring
high-performance switching and frame forwarding. The
switching core is designed to deliver wire-speed capabilities,
with a fully integrated ASIC architecture that facilitates
hardware-assisted feature execution.
The 28-port models – ERS 5928GTS, and ERS 5928GTS-
uPWR – feature 24 1000BASE-T Gigabit Ethernet access
ports with RJ45 interfaces; these ports also support
10/100Mbps connectivity. Four SFP+ interfaces provide
for network uplink connectivity, and these ports support
both Gigabit and 10 Gigabit pluggable transceivers. The
new ERS 5928MTS-uPWR model features 24 1000BASE-T
Gigabit/2.5 Gigabit Ethernet access ports with RJ45
interfaces; these ports also support 100Mbps connectivity.
As with all other ERS 5900 model, four SFP+ interfaces
provide for network uplink connectivity, and these ports
support both Gigabit and 10 Gigabit pluggable transceivers.
The 52-port models – ERS 5952GTS and ERS 5952GTS-
PWR+ – feature 48 1000BASE-T Gigabit Ethernet access
ports with RJ45 interfaces; these ports also support
10/100Mbps connectivity. Four SFP+ interfaces provide for
network uplink connectivity, and these ports support both
Gigabit and 10 Gigabit pluggable transceivers.
The 100-port models – ERS 59100GTS and ERS 59100GTS-
PWR+ – feature 96 1000BASE-T Gigabit Ethernet access
ports with RJ45 interfaces; these ports also support
10/100Mbps connectivity. Four SFP+ interfaces provide for
network uplink connectivity, and these ports support both
Gigabit and 10 Gigabit pluggable transceivers.
Importantly, all ERS 5900 models feature two dedicated
Stackable Chassis interfaces on the rear; one a bi-
directional uplink and the other a bi-directional downlink.
These QoS-aware high-speed connections enable a
resilient, high-performance hardware virtualization solution,
leveraging a shortest path algorithm to minimizes transit
hops in a multi-device configuration and supporting active-
active bi-directional trac flows.
The Power-over-Ethernet models – ERS 5928-PWR+, ERS
5952GTS-PWR+, and ERS 59100GTS-PWR+ support full
Standards-compliant IEEE 802.3af/802.3at PoE/PoE+
delivering up to 30W per port to power IP Phones, Wireless
Access Points, networked IP CCTV Cameras, and other
converged devices

.
The ERS 5928GTS-uPWR and 5928MTS-uPWR models
support the Four-Pair PoE initiative (a.k.a. Universal PoE),
enabling up to 60 Watts of power on access ports. This
capability can be used to support a greater range of high-
power devices through a single standard Ethernet cable,
such as premium telepresence systems, multi-radio Wireless
Access Points, VDI Thin Clients and monitors, trading
turrets used in the financial vertical, downstream compact
Switches, and even PoE-power smart lighting systems.
Four-Pair PoE is seen as a key enabling technology for the
Internet of Things. These models also support conventional
802.3af/802.3at PoE/PoE+.
These PoE models utilize field-replaceable, hot-swappable
power supplies that can each deliver up to 1,400W (or
1,000W when connected to 110VAC), while the non-PoE
models utilize a version that is rated at 450W. A portion of
power is reserved for system operation: 200W for the 28
and 52-port models, and 400W for the 96-port model.
PoE power budgets are as follows:
• ERS 5928GTS-uPWR+, 5928MTS-uPWR, and 5952GTS-
PWR+ – 1,440W of PoE power with 2 PSUs installed,
and up to 1,200W with a single PSU
• ERS 59100GTS-uPWR – 2,880W of PoE power with
4 PSUs installed, up to 2,880W with 3 PSUs, up to
2,580W with 2 PSUs, and up to 1,200W with a
single PSU
Benefits
The ERS 5900 products add significant flexibility to
an Enterprise’s networking capability. Deployed with
other Extreme or third-party Ethernet Switch devices,
the ERS 5900 products provide high-capacity, high-
performance connectivity solution for high-end Wiring
Closet applications.
The ERS 5900 products deliver key Enterprise-class
benefits, including:
• Always-On – Stackable Chassis delivers a best-
in-class high-availability solution, featuring hot-
swappable unit replacement and integrated power and
cooling redundancy.
• Convergence-Ready – flexible support for PoE/
PoE+, Universal PoE optimized for high-definition
video surveillance, true plug-and-play capabilities
for communications, collaboration, and engagement
deployments, and advanced QoS capabilities.
• Powerful – wire-speed performance, truly scalable
virtual backplane capabilities, delivering up to 672Gbps
of throughput to support large-scale deployments.
• Highly Secure – Standards-based 802.1X Network
Access Control can also be integrated with Extreme
Management Center for centralized, policy-based
authenticated network access. The ERS 5900 now also
supports MACsec for link layer encryption on both
Access and Uplink ports.

PoE+ Switch ports deliver up to 32.4 watts, with the “extra” 2.4W provided to compensate for potential line loss, and ensuring that a full 30W is available
to the Powered Device.
