The EX4650 line of Ethernet switches delivers high scale, high availability, and high performance for campus distribution deployments. 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 1U platform, the EX4650 provides the flexibility to support mixed 1GbE, 10GbE, 25GbE, 40GbE, and 100GbE environments.
Starting with Junos OS Release 18.3R1, the EX4650-48Y switch is available as a fixed-configuration switch with the following built-in ports:
Forty-eight 25-Gigabit Ethernet ports that+ can operate at 1-Gbps, 10-Gbps, or 25-Gbps speed and support SFP, SFP+, or SFP28 transceivers.
Eight 100-Gigabit Ethernet ports that can operate at 40-Gbps or 100-Gbps speed and support QSFP+ or QSFP28 transceivers. When these ports operate at 40-Gbps speed, you can configure four 10-Gbps interfaces and connect breakout cables, increasing the total number of supported 10-Gbps ports to 80. When these ports operate at 100-Gbps speed, you can configure four 25-Gbps interfaces and connect breakout cables, increasing the total number of supported 25-Gbps ports to 80.
A total of four models are available: two featuring AC power supplies and front-to-back or back-to-front airflow and two featuring DC power supplies and front-to-back or back-to-front airflow.
