Two line cards are available, one with and one without support for IEEE 802.3af Power over Ethernet (PoE) and 802.3at PoE+.
1.8 EX8200 Switches
EX8200 modular switches offer flexible platforms that deliver the port densities, scalability, and high availability required for today’s demanding campus core and data center environments.
The same line cards work in both EX8200 models, offering a variety of 10/100/1000BASE-T, 100BASE-FX/1000BASE-X, and 10GbE interfaces. An EX8208 can support 384 GbE or 64 10GbE ports at wire speed, or 320 10GbE ports in shared bandwidth applications. An EX8216 can support twice that number.
1.9 EX9200 Switches
EX9200 line of Ethernet switches provides a programmable, flexible, and scalable foundation for delivering mission-critical applications in campus and data center core environments.
Three EX9200 switches are available: the EX9204, EX9208 and EX9214. The EX9200 chassis deliver up to 240 Gbps (full duplex) per slot. A pass-through midline design supports capacity of up to 13.2 Tbps for built-in migration to next-generation deployments.
1.10 EX Series Options
EX Series options include the EX Series Redundant Power Supply for EX2200 and EX3300 Ethernet Switches, and the XRE200 External Routing Engine for managing EX8200 switches in a Virtual Chassis configuration.
2. QFX Series switches
QFX Series switches are high-performance, high-density platforms. QFX Series switches can be deployed as 10GbE, 40GbE or 100GbE access, spine, core or aggregation devices in Virtual Chassis, Virtual Chassis Fabric, Multi-Chassis LAG and Junos Fusion architectures.
