Arista DCS-7020R4M-48TX-4QC-F | 7020R4 48-Port 10G Switch, 4x 100G QSFP, TunnelSec

Q: What is TunnelSec encryption and how does it benefit my deployment?
A: TunnelSec provides line-rate hardware encryption using AES-256-GCM across MACsec, IPsec, and VXLANsec protocols. This enables secure point-to-point or multi-hop encrypted tunnels across third-party infrastructure without requiring separate encryption appliances, ideal for WAN, DCI, and multi-tenant data center deployments.

Q: Can this switch operate at both 1G and 10G speeds on the RJ45 ports?
A: Yes, all 48 RJ45 ports support auto-negotiation at 1G or 10G speeds, providing flexibility for mixed-speed environments and backward compatibility with legacy 1G infrastructure.

Q: What is the maximum configuration for 100G connectivity?
A: The switch provides 4 QSFP ports that can each operate at 100G, or can be broken out to support multiple lower-speed connections depending on optics and configuration requirements.

Q: Is this switch suitable for data center leaf or spine deployments?
A: Yes, the 7020R4 Series is purpose-built for high-performance edge applications including data center leaf layers, providing wire-speed Layer 2/3 forwarding, large routing tables, and deep buffers ideal for east-west traffic patterns.

Q: What does the '-F' suffix indicate in the model number?
A: The '-F' suffix indicates front-to-rear airflow configuration with fixed dual AC power supplies. This model is designed for cold-aisle intake deployments in standard data center environments.
