FAQs

Q: How many DCS-7512R-FM modules are required for a 7512 chassis?
A: Six DCS-7512R-FM fabric modules are required to populate all fabric slots (1-6) in the 7512 or 7512N chassis for full redundancy and non-blocking operation.

Q: Is the DCS-7512R-FM compatible with other 7500 series chassis?
A: No, this module is specifically designed for the 7512 and 7512N chassis. Each 7500R chassis model requires its own corresponding fabric module (7504R-FM, 7508R-FM, or 7516R-FM).

Q: What is the difference between DCS-7512R-FM and DCS-7512R3-FM?
A: The DCS-7512R-FM is designed for 7500R Series line cards, while the DCS-7512R3-FM is for the newer 7500R3 Series supporting higher-speed 400GbE line cards. Ensure your fabric modules match your line card generation.

Q: Can the fabric modules be replaced without shutting down the chassis?
A: Yes, the DCS-7512R-FM modules are hot-swappable, allowing replacement without powering down the chassis. However, it's recommended to follow Arista's hot-swap procedures to maintain fabric redundancy during replacement.

Q: What line cards are supported with the DCS-7512R-FM?
A: The 7512R-FM supports all 7500R and 7500E Series line cards, including the 7500R-36CQ (100GbE), 7500R-36Q (40GbE), and 7500E-36Q models. The 7512N chassis with R-FM modules supports up to 12 line cards.
