What is the switching capacity and performance?

The switch offers 2.88 Tbps throughput and 1 Bpps forwarding using Q5 ASICs. Features include 12 GB buffers, VOQ for no HOL blocking, 2.5 µs PFE latency, 256K MAC addresses, and 128K IPv4/IPv6 routes, suitable for high-scale Layer 3 operations.

What power and cooling options are included?

Ships with two redundant 1600W AC/DC power supplies (3200W total max, 800W typical) and three fan modules. This N+1 redundancy ensures high availability without single points of failure in mission-critical datacenters.

What is the form factor and physical size?

It's a fixed 2U rack-mount switch measuring 17.4 x 3.46 x 31 inches (44.2 x 8.8 x 78.7 cm), weighing about 50 lbs. Optimized for dense rack deployments with front-to-back airflow via three fans.

Does it support network overlays and protocols?

Yes, supports VXLAN L2/L3 gateway, EVPN-VXLAN, Contrail Networking, VMware NSX, and OVSDB. Ideal for virtualized overlays in multi-tenant clouds with high logical scale (4K VLANs, 192K ARP).

What CPU and memory does the Routing Engine have?

Features a 2.5 GHz quad-core Intel CPU with 16 GB SDRAM. Packet Forwarding Engines use Q5 ASICs connected to Hybrid Memory Cubes for buffering and scale, enabling 2.88 Tbps performance.
