Juniper Networks EX9214 Ethernet Switches provide high performance, scalable connecvity, and
carrier-class reliability for high-density environments such as campus-aggregaon and data-center
networks. The EX9214 switch has a throughput of up to 13.2 terabits per second (Tbps) or up to
240 gigabits per second (Gbps) per slot full duplex. The EX9214 switch is a modular system that
provides high availability and redundancy for all major hardware components, including Roung Engine
module (RE module), Switch Fabric module (SF module), fan trays, and power supplies.
2

You can manage EX9214 switches by using the same interfaces that you use for managing other devices
running the Juniper Networks Junos operang system (Junos OS)—the CLI, the Network and Security
Manager (NSM), and Junos Space.
Benets of the EX9214 Switch
Simplied 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 mulchassis
link aggregaon (MC-LAG) conguraon in the campus, you can use EX9214 switches to eliminate
Spanning Tree Protocol (STP); they collapse the core and aggregaon layers, thereby simplifying the
network architecture and network operaons. In a data center, you can use EX9204 switches to collapse
core and aggregaon layers. In combined campus and data center environments, EX9214 switches
consolidate network layers to simplify the network architecture and operaons.
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 encrypon, ensuring link-layer data
condenality, data integrity, and data origin authencaon.
Soware
The Juniper Networks EX Series Ethernet Switches run Junos OS, which provides Layer 2 and Layer 3
switching, roung, and security services.
Chassis Physical Specicaons
The EX9214 switch is 16 rack units (16 U) in size. Three EX9214 switches can t in a standard 48 U
rack. Each EX9214 switch is designed to opmize rack space and cabling.
See No Link Title on page 4, Figure 2 on page 5, and Figure 3 on page 6.

Host Subsystem
Switching and roung funconality, system management, and system control funcons of an EX9214
switch are performed by the host subsystem. The host subsystem consists of a Roung Engine
funconing together with a Switch Fabric.
You must install either two or three host subsystems in the slots 7 through 9—labeled 0, 1, and 2 | 6—in
the front panel of the chassis. A base-conguraon EX9214 switch has two host subsystems. A
redundant-conguraon EX9214 switch has a third host subsystem. For more informaon, see "EX9214
Switch Conguraons" on page 9.
Line Cards
The EX9214 switch has 12 vercal line card slots. The line cards for EX9214 switches combine a Packet
Forwarding Engine and Ethernet interfaces in a single assembly. Line cards are eld-replaceable units
(FRUs) that you can install in the line card slots 1 through 6 (labeled 0 through 5) and 9 through 14
6

(labeled 6 through 11) on the front of the switch chassis. All line cards are hot-removable and hot-
insertable. You can install a line card or a host subsystem in slot 9—labeled 2 | 6.
Table 1 on page 7 lists the line cards available for EX9214 switches.

Cooling System
The cooling system in an EX9214 switch is a eld-replaceable unit (FRU). It consists of two fully
redundant hot-removable and hot-insertable fan trays and an air lter and provides front-to-back
chassis cooling. See "EX9214 Cooling System" on page 40.
Power Supplies
Power supplies for the EX9214 switch are fully redundant, load-sharing, and hot-removable and hot-
insertable FRUs. Each EX9214 switch chassis can hold up to four AC or DC power supplies. The power
supplies connect to the midplane, which distributes the power to the switch components depending on
their voltage requirements.
Table 2 on page 9 shows the details of the power supplies available for EX9214 switches.
