Arista DCS-7304X3-FM-F | 7300X3 Fabric Module for 4-Slot Chassis, Front-to-Rear

Q: Is this fabric module compatible with the older DCS-7304X chassis?
A: No, the DCS-7304X3-FM-F is specifically designed for the DCS-7304X3 chassis and is not backwards compatible with the original DCS-7304X chassis, which requires DCS-7304X-FM fabric modules.

Q: How many fabric modules are required for a DCS-7304X3 chassis?
A: Four fabric modules are required for the DCS-7304X3 chassis, one for each of slots 1-4. All four must be installed for the system to operate properly.

Q: What is the difference between -F and -R suffix models?
A: The -F suffix indicates front-to-rear airflow (blue handle), while -R models feature rear-to-front airflow (red handle). You must match the airflow direction across all modules in your chassis to ensure proper cooling.

Q: Can I mix DCS-7304X3-FM modules with older generation fabric modules?
A: No, all fabric modules in the chassis must be of the same generation. The 7300X3 fabric modules provide enhanced performance and are required when using 7300X3 series line cards.

Q: What line cards are supported with the 7300X3 fabric modules?
A: The DCS-7304X3-FM supports 7300X3 series line cards including the DCS-7300X3-32C-LC (32x 100GbE) and DCS-7300X3-48YC4-LC, providing higher density and bandwidth than previous generation modules.
