Data Sheet EX4650 ETHERNET SWITCH DATASHEET Product Description Product Overview The EX4650 line of Ethernet switches delivers high scale, high availability, and high performance for campus distribution deployments. The EX4650 offers fixed 1GbE/ 10GbE/25GbE ports with 40GbE/100GbE uplinks that support advanced campus environments, allowing them to provide the onramp to multicloud, to deploy cutting edge cloud applications, and to embrace IoT technology. It is also flexible enough for use in enterprise on-premises top-ofrack and service provider aggregation deployments. The EX4650 is onboarded, provisioned, and managed in the Juniper Mist Cloud Architecture. Mist Wired Assurance delivers better experiences for connected devices through AI-powered automation and service levels. The Juniper Networks® EX4650 Ethernet Switch delivers 4 Tbps of Layer 2 and Layer 3 connectivity to networked devices such as secure routers, servers, and other switches. Featuring 48 wire-speed 10GbE/25GbE small form-factor pluggable and pluggable plus transceiver (SFP/SFP+/SFP28) ports and 8 wire-speed 40GbE/100GbE quad SFP+ transceiver (QSFP+/QSP28) ports in a compact 1 U platform, the EX4650 provides the flexibility to support mixed 1GbE, 10GbE, 25GbE, 40GbE, and 100GbE environments. Four models are available: two featuring AC power supplies with front-to-back or back-to-front airflow, and two featuring DC power supplies with front-to-back or back-to-front airflow. All models include dual power supplies. Key Components The EX4650 switch includes native 25GbE (fiber only) and either 40GbE or 100GbE fixedconfiguration options with rich L2, L3, Ethernet VPN (EVPN), and MPLS features. The EX4650 switches run the same reliable, high-performance Juniper Networks Junos® operating system used by Juniper Networks EX Series and QFX Series Ethernet Switches, SRX Series Services Gateways, and Juniper routers, ensuring a consistent control plane feature implementation and user experience across the entire Juniper infrastructure. EX4650 Switch Models The EX4650 switch is a compact, 1 U platform that provides high throughput, very low latency, and a rich set of Junos OS features. The performance of the EX4650’s control plane is further enhanced with a powerful 2.3 GHz quad-core Intel CPU with 16 GB of memory and 64 GB SSD storage. The EX4650-48Y is a 25GbE/100GbE campus distribution switch offering 48 SFP28 transceiver ports and eight QSFP28 ports that can be configured as 8x40GbE or 8x100GbE ports, with an aggregate throughput of 4 Tbps or 2.98 Bpps per switch. For added flexibility, each QSFP28 port can also be configured as 4x25GbE ports using breakout cables, increasing the total number of supported 25GbE ports to 80 per switch. EX4650-48Y Highlights The EX4650-48Y switch features the following: • Support for high-density, multispeed 1GbE/10GbE/25GbE downlinks and 40GbE/ 100GbE uplinks for access and aggregation configurations, with up to 48 25GbE ports and up to eight 100GbE uplink ports in a 1 U platform • Throughput of up to 4 Tbps L2 and L3 performance, with latency as low as 550 nanoseconds • A 2.3 GHz quad-core Intel CPU with 16 GB memory and 64 GB SSD storage • Feature-rich automation capabilities with support for Python and Zero Touch Provisioning

EX4650 Ethernet Switch Datasheet - Campus Fabric or Core Distribution: A pair of interconnected EX4650 switches can provide EVPN L2 and L3 VXLAN gateway support. This eliminates the need for STP across the campus network by providing a multihoming capability from the access to the distribution layer, while distribution to the core is an L3 IP fabric using EVPN technology. The IP fabric can also extend to connect multiple enterprise buildings, while VXLAN allows stretching L2 across buildings. An IP Clos network between the distribution and the core layers can exist in two modes, both of which...
