You can manage EX4300 switches by using the CLI. You can manage EX4300 switches except the
Multigigabit switches EX4300-48MP and EX4300-48MP-S by using the J-Web graphical interface,
Junos Space, and Network Director. Starting in Junos OS Release 18.3R1, you can manage EX4300-48MP
and EX4300-48MP-S switches by using Junos Space and Network Director also.
This video provides a brief overview of the EX4300-48MP switch:

Benefits of the EX4300 Switch
Compact solution—The EX4300 switch is a modular single rack unit device that is an apt solution for
crowded wiring closets and access switch locations such as data center, campus, and branch office
environments. It provides carrier-class reliability of modular systems with the economics and flexibility of
stackable platforms.
Support for Virtual Chassis—EX4300 switches support Virtual Chassis technology. You can interconnect
up to 10 EX4300 switches to form a Virtual Chassis.
High availability—EX4300 switches provide high availability through redundant power supplies and fans,
graceful Routing Engine switchover (GRES), and nonstop bridging and routing when deployed in a Virtual
Chassis configuration.
Support for MACsec—EX4300 switches support IEEE 802.1AE MACsec, providing support for link-layer
data confidentiality, data integrity, and data origin authentication. The MACsec feature enables EX4300
to support 88 Gbps of near line-rate hardware-based traffic encryption on all Gigabit Ethernet and 10 Gigabit
Ethernet ports.
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.
