FAQs

Q: What is the difference between the DCS-7280QR-C36-F and DCS-7280QR-C36-R?
A: The -F suffix indicates front-to-rear airflow (air flows from port side to fan side), while the -R suffix denotes rear-to-front airflow (reverse direction). Choose based on your data center hot/cold aisle configuration requirements.

Q: Can the 100GbE QSFP ports be used with 40GbE optics?
A: Yes, the 12x 100GbE QSFP ports support backward compatibility with 40GbE QSFP+ transceivers, providing deployment flexibility for mixed-speed environments.

Q: What routing protocols does this switch support?
A: The 7280R Series supports full Layer 3 routing including BGP, OSPF, IS-IS, MPLS (LDP, RSVP-TE), Segment Routing, EVPN, VXLAN, and 128-way ECMP for advanced routing and network virtualization.

Q: Is this switch suitable for spine or leaf deployment?
A: Yes, the DCS-7280QR-C36-F is designed as a universal spine/leaf switch. Its high port density and deep buffers make it ideal for both spine and leaf roles in modern Clos architectures.

Q: What power supply options are compatible with this model?
A: Compatible power supplies include PWR-745AC-F (745W front-to-rear), PWR-500AC-F (500W front-to-rear), and PWR-500-DC-F (500W DC). Always match the airflow direction (-F for front-to-rear) with your switch model.
