and service provider aggregation
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:
• A 128 Gbps Virtual Chassis module
• An 8x10GBASE-T copper expansion module
• An 8x10GBASE SFP/SFP+ fiber expansion module
• A 2x40GbE QSFP+ expansion module
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.
