EX2200-48P-4G Overview:

The Juniper Networks EX2500 line of Ethernet switches delivers a compact, powerful solution for high-density data center top-of-rack access switch deployments where high performance, low latency, high availability (HA), and energy efficiency are key requirements.

Featuring 24 wire-speed 10-Gigabit Ethernet SFP+ ports in a one rack-unit (RU) platform, Juniper Networks® EX2500 line of Ethernet switches delivers the performance and functionality needed to accelerate the deployment of latency-sensitive, business-enabling applications and services across the network.

By targeting high-density 10-Gigabit Ethernet top-of-rack deployments in the data center, the EX2500 line provides the perfect complement to the rest of the Juniper Networks EX Series Ethernet Switches: the Juniper Networks EX3200 line of Ethernet switches, designed for low-density Gigabit Ethernet access deployments; the Juniper Networks EX4200 line of Ethernet switches, designed for high-density data center and campus Gigabit Ethernet access and aggregation deployments; and the Juniper Networks EX8200 line of Ethernet switches, designed for data center and campus 10-Gigabit Ethernet core and aggregation environments.

Architecture and Key Components

Two versions of the EX2500 line of Ethernet switches are available: the EX2500-24F-FB, which offers front-to-back airflow; and the EX2500-24F-BF, which offers back-to-front airflow. Unlike most switches, which offer only front-to-back cooling, the EX2500 switches can be mounted with ports facing either the hot or cold aisle, depending on which is closer to the server network ports, keeping cable lengths short and more easily managed.

The EX2500 supports 10 Gbps SFP+ SR and LR optics, as well as direct-attach cables, which can be used to directly attach servers to the switch without optical transceivers or fiber-optic patch cables. The EX2500 can be managed via SNMP v1/v2/v3 or an embedded Web UI.

Features & Benefits:

Features	Benefits
Wire-Rate, Low-Latency Performance	The EX2500 delivers 480 Gbps throughput (full duplex) for any size packets. All ports are non-blocking with deterministic latency in the order of 700 nanoseconds.
Deployment Flexibility	The EX2500 supports both back-to-front and front-to-back cooling, which provides deployment flexibility and consistency with server designs for hot- and cold-aisle deployments. Front- and rear-facing configuration options ensure closer proximity of network access ports to server Ethernet ports, optimizing performance and keeping cable lengths short and manageable.
High Availability (HA)	The EX2500 offers dual internal, load-sharing AC power supplies and redundant, variable-speed fans as standard features, protecting the switch from a single power supply or fan failure.
Energy Efficiency	The EX2500 improves cooling efficiency via redundant variable-speed fans that automatically adjust their speed based on existing conditions to reduce power consumption.
Deployment Scenarios	The EX2500 switches are designed for high-density 10-Gigabit Ethernet data center top-of-rack applications where high performance, low latency, HA, and energy efficiency are critical. Line-rate, high-bandwidth, cut-through switching, filtering and traffic-queuing features enable the EX2500 to keep traffic moving, while redundant power and fans ensure the switch is always available for business-sensitive operations. The low latency offered by the EX2500—approximately 700 nanoseconds—makes it ideal for delay-sensitive applications such as high-performance server clusters and financial applications.
