Juniper EX4200 Switch

Juniper Networks EX4200 Ethernet Switches provide connectivity for medium- and high-density environments and scalability for growing networks. These switches can be deployed wherever you need high density of Gigabit Ethernet ports (24 to 480 ports) or redundancy. Typically, 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.

Individually, the EX4200 offers a number of HA features that are typically associated with modular chassis-based switches. When combined with the field-proven Junos OS and L2/L3 failover capabilities, these features provide the EX4200 with true carrier-class reliability.

Redundant power supplies:
The EX4200 line of Ethernet switches support internal redundant, load-sharing, hot- swappable and field-replaceable AC and DC power supplies to maintain uninterrupted operations. Thanks to their compact footprint, the EX4200 requires significantly less power than chassis-based switches delivering equivalent port densities.

Hot-swappable fan tray with multiple blowers:
The EX4200 includes a hot-swappable, field-replaceable fan tray with three blowers, providing sufficient cooling even if one of the blowers were to fail.

Redundant Trunk Group (RTG):
To avoid the complexities of the Spanning Tree Protocol (STP) without sacrificing network resiliency, the EX4200 employs redundant trunk groups to provide the necessary port redundancy and simplify switch configuration.

Cross-member link aggregation:
Cross-member link aggregation allows redundant link aggregation connections between devices in a single Virtual Chassis configuration, providing an additional level of reliability and availability.

Carrier-class hardware:
The EX4200 leverages a purpose- built packet forwarding engine ASIC, the EX-PFE, which integrates much of the same intellectual property used in Juniper Networks carrier routers. As a result, the EX4200 delivers the same predictable, scalable functionality found in the world’s largest networks.

Non-Stop Bridging (NSB) and Non-Stop Routing (NSR):
NSB and NSR on the EX4200 ensure control plane protocols, states and tables are synchronized between Master and Standby REs to prevent protocol flaps or convergence issues following a Routing Engine failover.

Non-Stop Software Upgrade (NSSU):
With NSSU, all members of a Virtual Chassis system can be upgraded with a single command. Mission-critical traffic can be configured as a link aggregate across multiple Virtual Chassis switch members, ensuring minimal disruption during the upgrade process.

IPv4 and IPv6 routing support:
IPv4 and IPv6 Layer 3 routing (OSPF and PIM) is available in the base license, enabling highly resilient networks.
