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.

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.

See Figure 16, Figure 17, and Figure 18.

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 23 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 Cooling System and Airflow in an EX9214 Switch.

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