FAQs

Q: What is the difference between the DCS-7280SR-48C6-F and DCS-7280SR-48C6-R?
A: The -F suffix indicates front-to-rear airflow where cool air enters from the non-port side and exhausts from the port side, while the -R suffix denotes rear-to-front airflow. Choose the airflow direction that matches your data center cooling design.

Q: Can the 100G QSFP ports be used for lower-speed connectivity?
A: Yes, the six 100G QSFP ports support breakout configurations to 4x25G or 4x10G, providing up to 24 additional 25G or 10G ports for flexible connectivity options.

Q: What deployment scenarios is the DCS-7280SR-48C6-F best suited for?
A: This switch is ideal for high-density 10G leaf-spine architectures, data center aggregation layers, IP storage networks requiring deep buffers and low latency, and cloud environments with mixed 10G and 100G connectivity needs.

Q: Does this model support Layer 3 routing and EVPN/VXLAN?
A: Yes, the 7280R series provides full Layer 2 and Layer 3 switching and routing capabilities, including BGP, MPLS, EVPN/VXLAN overlay networks, and ECMP for scalable data center designs.

Q: What is the benefit of the 4 GB deep packet buffer?
A: The deep VOQ buffer architecture eliminates head-of-line blocking and absorbs traffic bursts without packet loss, making it ideal for converged networks handling storage, real-time, and bursty traffic patterns simultaneously.
