System Overview

The EX4650 line of Ethernet switches delivers high scale, high availability, and high performance for campus distribution

deployments. Featuring 48 wire-speed 10-Gigabit Ethernet/25 Gigabit Ethernet small form-factor pluggable and pluggable

plus transceiver (SFP/SFP+/SFP28) ports and 8 wire-speed 40 Gigabit Ethernet/100 Gigabit Ethernet quad SFP+ transceiver

(QSFP+/QSP28) ports in a compact platform, the EX4650 provides the flexibility to support mixed environments. The

EX4650 switches run standard Junos operating system (OS). QFX5120-48Y switches also support virtual chassis technology.

You can interconnect up to two EX4650-48Y switches in a EX4650-48Y virtual chassis.
