FAQs

Q: How many DCS-7516R-FM modules are required for a 7516 chassis?
A: Up to six DCS-7516R-FM modules are required to populate fabric slots 1-6 in the Arista 7516N/7516R chassis. Full population is recommended for maximum bandwidth and redundancy in production environments.

Q: Is the DCS-7516R-FM hot-swappable?
A: Yes, the DCS-7516R-FM fabric module is hot-swappable, allowing maintenance or replacement without powering down the chassis or disrupting traffic on operational line cards and supervisors.

Q: What is the difference between DCS-7516R-FM and other fabric modules?
A: The DCS-7516R-FM is designed specifically for the 7516 chassis with higher power capacity and throughput to support 16 line card slots. It is not compatible with smaller 7504, 7508, or 7512 chassis models.

Q: What power supplies are compatible with the 7516 chassis?
A: The 7516 chassis supports PWR-3KT-AC-RED, PWR-3K-DC-RED, and PWR-3KT-HV-RED 3kW power supplies. A fully loaded chassis with DCS-7516R-FM modules requires sufficient PSU capacity for redundancy.

Q: Does the DCS-7516R-FM require a separate license?
A: No, the fabric module itself does not require a separate license. Licensing is applied at the supervisor and line card level based on feature requirements and Arista EOS software subscriptions.
