You can manage EX9214 switches by using the same interfaces that you use for managing other devices
running the Juniper Networks Junos operating system (Junos OS)—the CLI, the Network and Security
Manager (NSM), and Junos Space.
Benefits of the EX9214 Switch
Simplified network architecture—EX9214 switches deliver a simple, secure, virtualized network
environment that increases business agility. They are ideal for simplifying campus, data center, and
combined campus and data center network environments by collapsing network layers. In a multichassis
link aggregation (MC-LAG) configuration in the campus, you can use EX9214 switches to eliminate
Spanning Tree Protocol (STP); they collapse the core and aggregation layers, thereby simplifying the
network architecture and network operations. In a data center, you can use EX9204 switches to collapse
core and aggregation layers. In combined campus and data center environments, EX9214 switches
consolidate network layers to simplify the network architecture and operations.
MACsec support—EX9200-40F-M and EX9200-40XS line cards and EX9200-20F-MIC for EX9200-
MPC line card supports IEEE 802.1AE MACsec with AES-256 bit encryption, ensuring link-layer data
confidentiality, data integrity, and data origin authentication.
Software
The Juniper Networks EX Series Ethernet Switches run Junos OS, which provides Layer 2 and Layer 3
switching, routing, and security services.
Chassis Physical Specifications
The EX9214 switch is 16 rack units (16 U) in size. Three EX9214 switches can fit in a standard 48 U
rack. Each EX9214 switch is designed to optimize rack space and cabling.
