Summit X460 Series—Page 2
High-Performance and Highly Scalable Switching and Routing
High-Performance Switching
and Routing
Summit X460 is available in six different
port configuration options: 28-port Gigabit
Ethernet (Summit X460-24t/24p/24x),
48-port fiber Gigabit Ethernet
(Summit X460-48x), or 52-port Gigabit
Ethernet (Summit X460-48t/48p). All
ports run at non-blocking, wire-speed
performance and can carry wire-rate
traffic to the option slots, which allow
flexible configuration. Option slot A
supports a two-port 10 GbE module
(XGM3-2sf). For SummitStack stacking
ports, a two-port SummitStack module
or two-port SummitStack-V80 module
can be installed in option slot B (See
Figure 1: Port configuration options for
Summit X460 switches).
Flexible Port Configuration
Summit X460 offers very flexible port
configurations. For Summit X460-24t/24p,
with four dedicated Gigabit Ethernet fiber
ports and four shared Gigabit Ethernet
fiber ports, the switch can have up to 8
fiber GbE ports, while still providing 20
Gigabit Ethernet copper ports (PoE-plus
or non-PoE). If higher density copper
ports are required, the switch can provide
up to 24 Gigabit Ethernet copper ports
while providing 4 Gigabit Ethernet fiber
ports. Through the two option slots,
Summit X460 switches can be equipped
with an additional two 10 Gigabit
Ethernet and/or SummitStack stacking
ports. For stacking, depending upon the
needs for bandwidth across the units in a
stack, Summit X460 supports 40 Gbps
SummitStack or 80 Gbps
SummitStack-V80 stacking option
modules (See Figure 2: Summit X460-24t
flexible port configuration).
SummitStack and
SummitStack-V80—
High-Performance Stacking
Summit X460 supports SummitStack,
which provides 40 Gbps (SummitStack
module) or 80 Gbps (SummitStack-V80
module) of stacking bandwidth. The
SummitStack module offers high-speed
40 Gbps stacking performance, and
provides compatibility with the
Summit X250e, Summit X450a/e,
Summit X480 and Summit X650
stackable switches.
Alternatively, you may choose high-speed
80 Gbps stacking, which is ideal for
demanding applications where a high
volume of traffic traverses through the
stacking links, yet bandwidth is not
compromised through stacking.
SummitStack-V80 also breaks the distance
limitation for stacking technology by using
QSFP+ technology. SummitStack-V80 can
support passive copper cable (up to 5m),
active multi-mode fiber cable (up to 100m),
and QSFP+ optical transceivers which will
be the standard technology for 40 GbE.
With SummitStack-V80, the Summit X460
provides a very flexible stacking solution
inside the data center or central office to
create a virtualized switching infrastruc-
ture across rows of racks. (See Figure 3:
SummitStack-V80 across Rows of Racks
and Figure 4: 40 GbE Cabling for
SummitStack-V80)
SummitStack-V
Flexible Stacking Over 10
Gigabit Ethernet
ExtremeXOS supports the new
SummitStack-V capability to utilize 10 GbE
ports as stacking ports, enabling the use of
standard cabling and optics technologies
used for 10 GbE such as XFP, SFP+,
10GBASE-T and XENPAK. SummitStack-V
provides long-distance stacking connectiv-
ity of up to 40 km while reducing the cable
complexity of implementing a stacking
solution. SummitStack-V enabled 10 GbE
ports must be physically direct-connected.
Summit X460 offers sophisticated intelligent switching and routing with exceptional port density, scalability and virtualiza-
tion support plus high-performance stacking technology powered by the ExtremeXOS modular OS. Summit X460 helps
enhance the data center, Carrier Ethernet and enterprise campus edge and aggregation network.
