class scale, high availability, and
(QSFP+) ports in a compact one rack unit (1 U) platform, the Juniper Networks® EX4600
high performance to campus
Ethernet Switch delivers 1.44 Tbps of Layer 2 and Layer 3 connectivity to networked devices
distribution deployments. The
EX4600 offers fixed 10 Gpbs
and modular 10 Gpbs and 40
Gbps ports, giving it the flexibility
to also be implemented in
such as secure routers, servers, and other switches. The EX4600 base switch provides 24
fixed 1GbE SFP/10GbE SFP+ ports1 and 4 fixed 40GbE QSFP+ ports, providing the flexibility
to support mixed 1GbE, 10GbE and 40GbE environments. A total of four models are available:
two featuring AC power supplies and front-to-back or back-to-front airflow; and two
data center top-of-rack and
featuring DC power supplies and front-to-back or back-to-front airflow. Each model includes
service provider aggregation
dual power supplies.
All versions feature two expansion slots that can accommodate optional expansion
modules, providing tremendous configuration and deployment flexibility for enterprise
distribution networks. Two expansion modules are available:
• 8xGBASE/10GBASE SFP/SFP+ fiber expansion module2
• 4x40GbE QSFP+ expansion module3
Architecture and Key Components
Virtual Chassis Technology
The EX4600 supports Juniper Networks’ unique Virtual Chassis technology, which enables
up to 10 interconnected switches to operate as a single, logical device with a single IP
address. Virtual Chassis technology enables enterprises to separate physical topology from
logical groupings of endpoints, ensuring efficient resource utilization. The EX4600 can
participate in the same Virtual Chassis configuration with the Juniper Networks EX4300
Ethernet Switch, delivering highly flexible and scalable configuration options for enterprise
distribution deployments.
EX4600 switches in a Virtual Chassis configuration can be connected using up to 16 of
the 10GbE or 40GbE ports in link aggregation groups (LAGs) across 10GbE/40GbE ports,
providing an aggregate backplane capacity of up to 1.04 Tbps.
In the data center, EX4600 Virtual Chassis deployments can extend across multiple topof-rack or end-of-row switches, providing tremendous configuration flexibility for 10GbE
server connectivity by only requiring redundant links between Virtual Chassis groups rather
than each physical switch to ensure high availability. In addition, mixed Virtual Chassis
configurations featuring EX4300 and EX4600 switches provide an ideal solution for data
centers with a mix of 1GbE and 10GbE servers, or for environments transitioning from 1GbE
to 10GbE server connectivity.
If GBASE-T transceivers are used, only 12 ports can operate in 1GbE mode as GBASE-T transceivers cannot be installed in
vertically adjacent ports due to physical constraints.
All eight ports on the 10GbE expansion module can also operate at 1GbE.
Any 40GbE QSFP+ port can be split into 10GbE using breakout cables, providing a maximum of 72 wire-speed 10GbE ports.

Features and Benefits
EX4600 Ethernet switches include the following key features
and benefits:
• High performance: Each EX4600 supports up to 1.44 Tbps
of bandwidth or 1.07 Bpps at the minimum Ethernet frame
size, with 24 line-rate 10GbE fixed ports, 4 40GbE fixed
ports, and 2 expansion slots that can each support either a
4x40GbE module or an 8x10GbE module.
• Intelligent buffer management: EX4600 switches have a
total of 12 MB shared buffers. While 25 percent of the total
buffer space is dedicated, the rest is shared among all ports
and is user configurable. The intelligent buffer mechanism
in the EX4600 effectively absorbs traffic bursts while
providing deterministic performance, significantly increasing
performance over static allocation.
• Insight technology for analytics: The EX4600 provides
dynamic buffer utilization monitoring and reporting with
an interval of 10 milliseconds to provide microburst and
latency insight. It calculates both queue depth and latency,
and logs messages when configured thresholds are crossed.
• Unified in-service software upgrade (unified ISSU): With

Data Sheet
• MPLS: EX4600 switches support a broad set of MPLS
features, including L2VPN, L3VPN, IPv6 provider edge
router (6PE), RSVP traffic engineering, and LDP to allow
standards-based network segmentation and virtualization.
The EX4600 can be deployed as a low-latency MPLS labelEX4600
switching router (LSR) or MPLS provider edge (PE) router in
smaller scale environments. The EX4600 is the industry’s
only compact, low-latency, high-density, low-power switch
to offer an MPLS feature set.
• MACsec: The EX4600 is capable of MACsec features on
all 10GbE ports to support 400 Gbps of near line-rate
hardware-based traffic encryption on all fiber ports, including
the base unit and optional 10GbE expansion modules.
MACsec in software will be enabled in a future release.
