EX9204 System Overview

EX9204 Switch Hardware Overview

Juniper Networks EX9204 Ethernet Switches provide high performance, scalable connectivity, and carrier-class reliability for high-density environments such as campus-aggregation and data-center networks. The EX9204 switch has a throughput of up to 1.6 terabits per second (Tbps) or up to 240 gigabits per second (Gbps) per slot full duplex.

You can manage EX9204 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 EX9204 Switch

Simplified network architecture—EX9204 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 EX9204 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, EX9204 switches consolidate network layers to simplify the network architecture and operations.

Support for MACsec—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

Juniper Networks EX Series Ethernet Switches run Junos OS, which provides Layer 2 and Layer 3 switching, routing, and security services.

Front and Rear Views of an EX9204 Switch

The EX9204 switch is five rack units (5 U) in size. Nine EX9204 switches can fit in a standard 48 U rack. Each EX9204 switch is designed to optimize rack space and cabling. See Figure 1, Figure 2, Figure 3, and Figure 4.

Host Subsystem

Switching and routing functionality, system management, and system control functions of an EX9204 switch are performed by the host subsystem. The host subsystem consists of a Routing Engine functioning together with a Switch Fabric.

An EX9204 is a 4-slot chassis that provides two dedicated slots—labeled 1 and 2—for line cards, one dedicated slot—labeled 0—for a host subsystem, and one multifunction slot—labeled 1|0—for either a line card or a host subsystem.

You can install either one or two host subsystems in an EX9204 switch. A base-configuration EX9204 switch has one host subsystem. A redundant-configuration EX9204 switch has a second host subsystem. For more information, see EX9204 Switch Configurations.

Line Cards

Line cards are field-replaceable units (FRUs) that you can install in the line card slots and in the multifunctional slot on the front of the switch chassis. All line cards are hot-removable and hot-insertable.

You can install up to three line cards in an EX9204 switch. Each EX9204 switch has two dedicated line card slots—labeled 1 and 2—and a multifunction slot—labeled 1|0—that you can use for either a line card or a host subsystem.

The line cards in EX9204 switches combine a Packet Forwarding Engine and Ethernet interfaces in a single assembly. Table 1 lists the line cards available for EX9204 switches.

Cooling System

The cooling system in an EX9204 switch is a field-replaceable unit (FRU). It consists of a hot-removable and hot-insertable fan tray. The fan tray contains three fans. The fan tray installs vertically on the right back of the chassis and provides side-to-side chassis cooling. See EX9204 Cooling System.

Power Supplies

Power supplies for the EX9204 switch are fully redundant, load-sharing, and hot-removable and hot-insertable FRUs. Each EX9204 switch chassis can hold up to four AC or up to two DC power supplies.

Table 2 shows the details of the power supplies available for EX9204 switches.

You can mount an EX9204 switch on a standard 19-in. four-post rack or a standard 800-mm enclosed cabinet. You can mount up to eight EX9204 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.
