Juniper EX4650-48Y-AFI 25GbE/100GbE Data Center Ethernet Switch

• 48 SFP28 ports with 1/10/25GbE support: Enables dense server and network-device connectivity while allowing organizations to migrate from 10GbE to 25GbE without replacing the switching platform. 
• 8 QSFP28 uplink ports: Provides 40GbE or 100GbE connectivity for high-capacity spine, aggregation, and inter-switch links. 
• Breakout and channelization support: Allows selected 40/100GbE ports to be configured for additional 10/25GbE interfaces, increasing deployment flexibility and port utilization. 
• Junos OS Layer 2 and Layer 3 networking: Delivers switching, routing, and security capabilities through a mature network operating system, reducing the need for separate platforms for core network functions. 
• EVPN-VXLAN support: Provides a foundation for scalable overlay networking and modern data center fabric architectures. 
• Virtual Chassis, MC-LAG and ESI-LAG: Supports resilient architectures and simplified logical network operations for environments where uptime and redundancy are priorities. 
• 1U fixed configuration: Packs high-speed port density into a compact rack footprint, helping reduce rack-space consumption.
• Redundant 1+1 650W AC power supplies: Maintains power redundancy while supporting continuous network operation if one power supply fails. 
• 4+1 redundant fan configuration: Provides cooling redundancy for higher availability in data center deployments. 
• Back-to-front airflow on AFI model: Aligns cooling direction with racks designed for this airflow pattern.
