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 switchesJ-EX4200 SwitchesJ-EX4200 switches provide connectivity for medium- and high-density environmentsand scalability for growing networks. These switches can be deployed wherever you needa 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 datacenters where they can be positioned as the top device in a rack to provide connectivityfor all the devices in the rack.You can connect individual J-EX4200 switches together to form one unit and managethe unit as a single chassis, called a Virtual Chassis. You can add more member switchesto 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 8ports equipped for PoE. All models provide ports that have 10/100/1000Base-T GigabitEthernet connectors and optional 1-gigabit small form-factor pluggable (SFP) transceiversor 10-gigabit small form-factor pluggable (SFP+) transceivers.Additionally, a 24-port model provides 100Base-FX/1000Base-X SFP ports. This modelis typically used as a small distribution switch.All J-EX4200 switches have dedicated 64-Gbps Virtual Chassis ports that allow you toconnect the switches to each other. You can also use optional uplink module ports toconnect 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. Anoptional additional connection to an external power source is also available.• A field-replaceable fan tray with three fans. The switch remains operational if a singlefan fails.• Redundant Routing Engines in a Virtual Chassis configuration. This redundancy enablesGRES (graceful Routing Engine switchover) and nonstop active routing.• Junos OS with its modular design that enables failed system processes to gracefullyrestart.Uplink ModulesOptional uplink modules are available for all J-EX4200 switches. Uplink modules providefour 1-gigabit small form-factor pluggable (SFP) transceivers or two 10-gigabit smallform-factor pluggable (SFP+) transceivers. You can use SFP or SFP+ ports to connect4Dell PowerConnect J-Series J-EX4200 Ethernet Switch Hardware Guide
