FAQs

Q: What components are included with the DCS-7504N-CH chassis?
A: The DCS-7504N-CH is an empty chassis only. Power supplies, supervisor modules, line cards, and fabric modules must be ordered separately to build a functional system.

Q: What line cards are compatible with the 7504N chassis?
A: The 7504N supports Arista 7500R, 7500R2, 7500R2A, and 7500R3 Series line cards, offering flexible port densities from 10GbE to 100GbE and beyond. It also provides backward compatibility with 7500E Series line cards.

Q: Can I mix AC and DC power supplies in the same chassis?
A: No, all power supplies in the chassis must be the same type (either all AC or all DC). The chassis supports redundant N+N grid power configurations for high availability.

Q: What is the difference between the 7504N and older 7504 chassis?
A: The 7504N is part of the newer 7500R2/R3 generation with improved fabric architecture, higher throughput (38 Tbps vs. 30 Tbps), and support for next-generation line cards including AlgoMatch and FlexRoute capabilities.

Q: Does the chassis require any licensing?
A: Yes, advanced features such as full routing tables (2M routes), EVPN, VXLAN, SR, and MPLS require FlexRoute or other feature licenses, which are purchased separately based on the specific chassis model and deployment requirements.
