FAQs

Q: What line cards are compatible with the DCS-7508N-CH chassis?
A: The DCS-7508N-CH supports Arista 7500R and 7500R3 Series line cards, including 36-port 100GbE, 24-port 400GbE, 48-port 10GbE with 100G uplinks, and flexible 25G/400G combination modules. The chassis offers backward compatibility with earlier 7500R line cards while supporting the latest 7500R3 fabric modules for maximum throughput.

Q: Does this chassis come with power supplies and supervisor modules?
A: No, the DCS-7508N-CH is an empty chassis only. Power supplies (AC or DC), fabric modules, supervisor modules, and line cards must be ordered separately. Typical bundle configurations include 6x 3kW power supplies, 6x fabric modules, and 1-2 supervisor modules depending on redundancy requirements.

Q: What is the maximum switching capacity of the 7508N chassis?
A: When configured with 7500R3 fabric modules and line cards, the DCS-7508N-CH supports up to 230Tbps of total system throughput. With 7500R fabric modules, capacity is 115-150Tbps depending on configuration. The modular design allows incremental scaling as network demands grow.

Q: What deployment scenarios is this chassis best suited for?
A: The DCS-7508N-CH is ideal for large-scale data centers requiring high-density 10G/25G/100G/400G connectivity, spine-leaf architectures, internet peering applications, data center interconnect, and campus core switching. It supports MLAG, ECMP, VXLAN overlays, and MPLS/EVPN for flexible network designs.

Q: What warranty and support options are available for this chassis?
A: Arista provides a standard one-year limited hardware warranty with 10 business day turnaround. Extended support options including next business day and 4-hour advance hardware replacement are available through Arista or authorized partners. All modules run Arista EOS with lifetime software updates.
