EX9214 System Overview

EX9214 Switch Hardware Overview

Juniper Networks EX9214 Ethernet Switches provide high performance, scalable connectivity, and carrier-class reliability for high-density environments such as campus-aggregation 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 Routing Engine module (RE module), Switch Fabric module (SF module), fan trays, and power supplies.

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.

Host Subsystem

Switching and routing functionality, system management, and system control functions of an EX9214 switch are performed by the host subsystem. The host subsystem consists of a Routing Engine functioning 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-configuration EX9214 switch has two host subsystems. A redundant-configuration EX9214 switch has a third host subsystem. For more information, see EX9214 Switch Configurations.

Line Cards

The EX9214 switch has 12 vertical line card slots. The line cards for EX9214 switches combine a Packet Forwarding Engine and Ethernet interfaces in a single assembly. Line cards are field-replaceable units (FRUs) that you can install in the line card slots 1 through 6 (labeled 0 through 5) and 9 through 14 (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 lists the line cards available for EX9214 switches.

Cooling System

The cooling system in an EX9214 switch is a field-replaceable unit (FRU). It consists of two fully redundant hot-removable and hot-insertable fan trays and an air filter and provides front-to-back chassis cooling. See EX9214 Cooling System.

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 shows the details of the power supplies available for EX9214 switches.

You can mount an EX9214 switch on a standard 19-in. four-post rack or a standard 800-mm enclosed cabinet. You can mount up to three EX9214 switches in a standard 48 rack unit (U) rack.

Field-Replaceable Units in an EX9200 Switch

Field-replaceable units (FRUs) are switch components that you can replace at your site. The EX9200 switch uses the following types of FRUs:

  • Hot-insertable and hot-removable—You can remove and replace these components without powering off the switch or disrupting the switching function.

  • Hot-pluggable—You can remove and replace these components without powering off the switch, but the switching function is interrupted until you replace the component.

Table 6 lists the FRUs for the EX9200 switch and their types.

Note:

If you have a Juniper J-Care service contract, register any addition, change, or upgrade of hardware components at https://www.juniper.net/customers/support/tools/updateinstallbase/ . Failure to do so can result in significant delays if you need replacement parts. This note does not apply if you replace existing components with the same type of component.
