Q: What components are included with the DCS-7816-CH chassis?
A: The DCS-7816-CH is a chassis-only SKU that includes the 16-slot chassis and extended rack mounting kit. Power supplies, fabric modules, supervisor modules, and line cards must be ordered separately to build a complete system.

Q: What is the difference between the DCS-7816-CH and DCS-7816L-CH?
A: The DCS-7816-CH supports 12 fabric module slots for maximum throughput of 460 Tbps, while the DCS-7816L-CH (lower density variant) supports 6 fabric module slots with 230 Tbps maximum throughput. Both offer 16 line card slots.

Q: Which line cards are compatible with the 7816 chassis?
A: The 7816 chassis supports all Arista 7800R3 and 7800R3A series line cards, including 100G, 400G, and encryption-enabled variants. Line cards can be mixed within the chassis for flexible deployment of 10G, 25G, 40G, 50G, 100G, and 400G interfaces.

Q: What deployment scenarios is the 7816 chassis suited for?
A: The DCS-7816-CH is designed for hyperscale data center spine and core applications, large-scale cloud networks, service provider peering, and data center interconnect (DCI) deployments requiring maximum port density and throughput.

Q: Does the chassis support high-availability configurations?
A: Yes, the 7816 chassis supports dual redundant supervisors, redundant power supplies (N+N or N+1), and active-active fabric modules with graceful degradation. All major components are hot-swappable for continuous operation during maintenance.
