Arista DCS-7388X5-64D-F | 7388X5 64-Port 400G Modular Switch, 25.6Tbps, 4RU

Q: What type of deployments is the DCS-7388X5-64D-F suited for?
A: This switch is optimized for large-scale hyperscale data center spine and leaf architectures, AI/ML cluster networking, and high-radix cloud environments requiring consistent low latency and maximum 400G port density in a compact 4RU form factor.

Q: Is the DCS-7388X5-64D-F field-configurable?
A: Yes, the 7388X5 is a modular system with 8 hot-swappable interface module slots. You can mix and match different I/O modules including 8-port 400G and 16-port 200G cards to customize port density and speed, allowing flexible migration paths as network requirements evolve.

Q: What licensing is required for advanced features?
A: The base Arista EOS software is included with the system. Advanced routing features like BGP-EVPN, VXLAN, and MPLS require the optional EOS Flex-route Lite or full feature licenses. CloudVision automation and telemetry is available as a subscription.

Q: Does this model support MACsec encryption?
A: Yes, the DCS-7388X5-64D-F includes 8 x DCS-7388-8D modules with integrated MACsec support on all 400G QSFP-DD ports, enabling line-rate encryption for secure data transmission within and between data centers.

Q: What airflow direction does the -F suffix indicate?
A: The -F suffix indicates front-to-rear (port side to exhaust side) airflow, which is standard for cold-aisle containment data center designs. Power supplies, fans, and modules must all match this airflow direction for proper cooling.
