Switches & Bridges

Network operators are increasingly deploying scale-out, spine-and-leaf IP fabric architectures, built with fixed-configuration switches to support growing east-west traffic in the data center. The Juniper Networks® QFX5200 line of next-generation, fixedconfiguration leaf/access switches offers flexible, cost-effective, high-density 10GbE, 25GbE, 40GbE, 50GbE, and 100GbE interfaces for server and intra-fabric connectivity, providing deployment versatility, investment protection, and future-proofing for today's data centers.
In addition to leaf deployments in IP fabric architectures, the QFX5200 switches are also a great fit for multitier, multichassis link aggregation (MC-LAG) network implementations commonly used in enterprise networks.
Like other QFX Series switches, the QFX5200 supports advanced Layer 2, Layer 3, and MPLS features. For large public cloud providers-among the first to adopt 25GbE servers to meet explosive workload growth-the QFX5200 enables very large, dense, and fast IP fabrics based on proven, Internet scale technology. For enterprise customers seeking investment protection as they transition their server farms from 10GbE to 25GbE, the QFX5200 line provides native 10GbE and 25GbE downlink ports as well as 40GbE and 100GbE uplink connections.
The QFX5200 runs the same reliable, high-performance Juniper Networks Junos® operating system used by network operators around the world. The QFX5200 supports a modular version of Junos OS that allows the switch's control plane and data plane processes and functions to run in parallel, maximizing utilization of the highperformance quad-core CPU.
QFX5200 Switch Models
The QFX5200 switches are compact, 1 U platforms that provide wire-speed packet performance, very low latency, and a rich set of Junos OS features. In addition to a high throughput Packet Forwarding Engine (PFE), the performance of the QFX5200 control plane is further enhanced with a powerful 1.8 GHz quad-core Intel CPU with 16 GB of memory and 64 GB SSD storage.
Two QFX5200 switch models are available:

• QFX5200-48Y: A 10GbE/25GbE data center access switch that offers 48 small formfactor pluggable plus (SFP+) transceiver ports or SFP28 ports and six QSFP28 ports. The six QSFP28 ports can be configured as 6x40GbE or 6x100GbE, with an aggregate throughput of 3.6 Tbps or 4.2 Bpps per switch.
• QFX5200-32C: A 100GbE data center access and aggregation switch that offers 32 quad small form-factor pluggable plus (QSFP+) transceiver or QSFP28 ports, with an aggregate throughput of 6.4 Tbps or 4.8 Bpps per switch. A QSFP28 module supports a 1x100GbE connection, 2x50GbE connections, or 4x25GbE connections using breakout cables. A QSFP+ module can provide a 1x40GbE connection or 4x10GbE connections using breakout cables.
