Arista DCS-7368X4-SC-F | 7368X4 Switch Card for 7368 Chassis, 12.8 Tbps, Front-to-Rear Airflow

Q: What is the DCS-7368X4-SC-F switch card used for?
A: The DCS-7368X4-SC-F is the core switching fabric card for the Arista 7368X4 modular chassis. It provides 12.8 Tbps of forwarding capacity and connects all 8 I/O module slots, enabling configurations from 128x 100G up to 32x 400G ports depending on the line cards installed.

Q: What does the '-F' suffix indicate?
A: The '-F' suffix indicates front-to-rear (forward) airflow direction. The switch card includes integrated high-performance fans that draw air from the front of the chassis and exhaust it through the rear, which is standard for most data center cooling configurations.

Q: Is this switch card compatible with all 7368 chassis models?
A: This switch card is specifically designed for the DCS-7368X4 modular chassis. It provides connectivity for up to 8 interface module slots and must be paired with a compatible supervisor module and power supplies to form a complete system.

Q: Can the switch card be replaced without shutting down the entire chassis?
A: The 7368X4-SC is a field-replaceable component designed for ease of maintenance. However, replacing the switch card is a service-affecting operation as it serves as the primary switching fabric. Proper planning and redundant network design are recommended for maintenance windows.

Q: What line cards are compatible with this switch card?
A: The 7368X4-SC supports various Arista 7368 series line cards including 100G QSFP28, 200G, and 400G QSFP-DD/OSFP interface modules. Each module slot receives 3.2 Tbps of bandwidth from the switch card, allowing flexible port speed configurations for leaf or spine deployments.
