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-of-rack and service provider aggregation deployments.
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.
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
