J-EX4200 Ethernet Switches have these features:
Run under Junos OS for J-EX Series switches
Have options of 24-port and 48-port models
Have options of full (all ports) or partial (8 ports) Power over Ethernet (PoE) capability
Have optional uplink modules that provide connection to distribution switches
J-EX4200 switches provide connectivity for medium- and high-density environments
and scalability for growing networks. These switches can be deployed wherever you need
a high density of Gigabit Ethernet ports (24 to 480 ports) or redundancy. Typically,
J-EX4200 switches are used in large branch offices, campus wiring closets, and data
centers where they can be positioned as the top device in a rack to provide connectivity
for all the devices in the rack.
You can connect individual J-EX4200 switches together to form one unit and manage
the unit as a single chassis, called a Virtual Chassis. You can add more member switches
to the Virtual Chassis as needed, up to a total of 10 members.
J-EX4200 switches are available in models with 24 or 48 ports and with no ports or 8
ports equipped for PoE. All models provide ports that have 10/100/1000Base-T Gigabit
Ethernet connectors and optional 1-gigabit small form-factor pluggable (SFP) transceivers
or 10-gigabit small form-factor pluggable (SFP+) transceivers.
Additionally, a 24-port model provides 100Base-FX/1000Base-X SFP ports. This model
is typically used as a small distribution switch.
All J-EX4200 switches have dedicated 64-Gbps Virtual Chassis ports that allow you to
connect the switches to each other. You can also use optional uplink module ports to
connect members of a Virtual Chassis across multiple wiring closets.
To provide carrier-class reliability, J-EX4200 switches include:
Dual redundant power supplies that are field-replaceable and hot-swappable. An
optional additional connection to an external power source is also available.
A field-replaceable fan tray with three fans. The switch remains operational if a single
fan fails.
Redundant Routing Engines in a Virtual Chassis configuration. This redundancy enables
GRES (graceful Routing Engine switchover) and nonstop active routing.
Junos OS with its modular design that enables failed system processes to gracefully
restart.
Optional uplink modules are available for all J-EX4200 switches. Uplink modules provide
four 1-gigabit small form-factor pluggable (SFP) transceivers or two 10-gigabit small
form-factor pluggable (SFP+) transceivers. You can use SFP or SFP+ ports to connect
