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.
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.
Benefits of the EX4650 Switch
EVPN-VXLAN campus architecture—The EX4650 switch extends EVPN-VXLAN beyond the data center,
thus providing customers the building blocks for an enterprise-wide fabric. The EVPN-VXLAN protocol is
suitable for campus architectures because it provides Layer 3 transport with Layer 2 capabilities that allow
enterprises to evolve, while also taking into consideration legacy applications. EX4650 also offers core
aggregation capabilities aimed at enterprises with campus networks that want a compact and highly scalable
solution.
Industry-leading 25-Gbps and 100-Gbps wire speeds: The EX4650 Switch offers industry-leading high
density 25-Gbps and 100-Gbps wire speeds that support 48 ports at 100-Gbps or 48 ports at 25-Gbps,
and 8 100-Gbps uplink ports.
Common data center protocols: Like the EX9000 series, the EX4650 also uses data center network
protocols. The network protocols used in the EX4650 are the Ethernet VPN (EVPN) and the Virtual
Extensible LAN (VXLAN). Engineers typically use it with the Border Gateway Protocol and the VXLAN
encapsulation protocol which creates an overlay network on an existing Layer 3 infrastructure. As a result,
the same engineering team can manage the data center and the campus.
Software
Juniper Networks EX Series Ethernet Switches run Junos OS™, which provides Layer 2 and Layer 3
switching, routing, and security services. The same Junos OS code base that runs on EX Series switches
also runs on all Juniper Networks M Series, MX Series, and T Series routers, and SRX Series Services
Gateways.
EX4650 Switch First View
The EX4650 switch has a 1 U form factor and is shipped with redundant fans (4+1) and redundant power
supplies (1+1).
The EX4650 switch is a 25-Gigabit Ethernet enhanced small form-factor (SFP28) switch with 48 SFP28
ports and 8 100-Gbps quad small form-factor (QSFP28) pluggable ports. Each SFP28 port can operate as
a native 25-Gigabit Ethernet port, 10-Gigabit Ethernet port, and can act as a 1-Gbps port based on the
transceivers inserted. Each of the eight uplink ports can operate as either 100-G or 40-G based on the
optics used. They can also be used as 25-Gbps ports or 10-Gbps ports using breakout cables or
channelization.
