Product Overview The Juniper Networks EX4550 line of Ethernet switches delivers scalable, high-performance platforms for supporting high-density 10 gigabit per second (Gpbs) data center top-ofrack as well as data center, campus, and service provider aggregation deployments. Product Description Featuring up to 48 wire-speed 1GbE or 10GbE small form-factor pluggable transceiver (SFP/SFP+) or 100M/1GBASE-T/10GBASE-T ports in a compact one rack unit (1 U) platform, the Juniper Networks® EX4550 Ethernet Switch delivers 480 Gbps of Layer 2 and Layer 3 connectivity to networked devices such as servers and other switches. Two versions of the EX4550 base switch are available: the EX4550-32F, a fiber-based version that provides 32 fixed 10GbE SFP/SFP+ pluggable ports; and the EX4550-32T, a copperbased version that supports 32 fixed 100M/1GBASE-T/10GBASE-T ports. Both versions feature two expansion slots, one in front and one in back, that can accommodate one of four optional expansion modules, providing tremendous configuration and deployment flexibility for campus and data center access and aggregation networks. The four expansion modules include: • 128 Gbps Virtual Chassis module A • n 8x10GBASE-T copper expansion module A • n 8x10GBASE SFP/SFP+ fiber expansion module A • 2x40GbE QSFP+ expansion module A Architecture and Key Components Virtual Chassis Technology The EX4550 supports Juniper Networks’ unique Virtual Chassis technology, which enables up to 10 interconnected switches to operate as a single, logical device with a single IP address. Virtual Chassis technology enables enterprises to separate physical topology from logical groupings of endpoints and, as a result, provides efficient resource utilization. The EX4550 can participate in the same Virtual Chassis configuration with any combination of Juniper Networks EX4200 and EX4500 Ethernet Switches, delivering highly flexible and scalable configuration options for campus and data center deployments. EX4550 switches in a Virtual Chassis configuration can be connected using dedicated 128 Gbps interconnect ports on the Virtual Chassis expansion module, or via link aggregation groups (LAGs) across 10GbE/40GbE ports, providing aggregate backplane capacity of up to 320 Gbps. In the data center, EX4550 Virtual Chassis deployments can extend across multiple topof-rack or end-of-row switches, providing tremendous configuration flexibility for 10GbE server connectivity by only requiring redundant links between Virtual Chassis groups rather than each physical switch to ensure high availability. In addition, mixed Virtual Chassis

configurations featuring EX4200, EX4500, and EX4550 switches provide an ideal solution for data centers with a mix of 1GbE and 10GbE servers, or for environments transitioning from 1GbE to 10GbE server connectivity. Data Center and Campus Advantages The EX4550 delivers a highly available, simple, and scalable 10GbE connectivity solution in a compact and power efficient platform, making it a perfect fit for both data center and campus networks. The EX4550 offers a number of other advantages for data center and campus deployments, including the following: Simple Virtual Chassis technology on...

Campus Deployments As business grows, the network needs to evolve. With its compact 1 U form factor and complete switch features, the EX4550 can be easily redeployed in different environments and physical layouts. Customers can also easily transition from 1GbE to 10GbE using the dual-speed interfaces on the EX4550-32T or by replacing 1GbE optics with 10GbE optics on the EX4550-32F. EX4550 switch capacity can be expanded without increasing the number of managed devices by simply adding more switches to the Virtual Chassis configuration. The EX4550 offers an economical, power efficient and...

In addition, the expansion slots on the EX4550-32T can support 10GbE SFP+ and 40GbE QSFP+ modules, which can be used as fiber uplinks or to extend connections beyond 100m. Customers introducing 10GbE into their server racks can use the EX4550 to add 10GbE-attached servers, iSCSI, and networkattached storage (NAS) with minimal impact to the current switching infrastructure. 10GbE Data Center Bridging and I/O Convergence Deployments The EX4550 is a full...
