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.
The EX4650-48Y switch offers 48 small-form factor pluggable (SFP+) ports that operate at 1-Gbps, 10-Gbps, and
25-Gbps speeds along with 8 quad small form-factor pluggable (QSFP28) ports that operate at 40-Gbps (with QSFP+
transceivers) and 100-Gbps speeds (with QSFP28 transceivers).

    NOTE: By default, the EX4650-48Y switch offers 10-Gbps speed. You need to configure to set 1-Gbps and 25-Gbps speeds. 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.
