FAQs

Q: What is the difference between the DC-F and standard F model?
A: The DCS-7280CR2-60-DC-F includes dual redundant DC power supplies designed for telco and carrier environments, while the F model uses AC power supplies. Both models share identical port configurations, performance specifications, and routing table sizes.

Q: Can the 100G ports be broken out to lower speeds?
A: Yes, each QSFP28 port supports flexible breakout configurations: 4x25GbE, 4x10GbE, or 2x50GbE. This allows up to 240 x 10GbE, 240 x 25GbE, or 120 x 50GbE total logical ports using standard breakout cables.

Q: What airflow direction does the DC-F variant support?
A: The DCS-7280CR2-60-DC-F features front-to-rear airflow where cool air enters from the non-port side and exhausts from the port side. This aligns with hot-aisle/cold-aisle data center cooling designs.

Q: What Layer 3 routing protocols are supported?
A: The switch supports full Layer 3 routing including BGP, OSPF, IS-IS, MPLS (LDP, RSVP-TE, BGP LU), SR-MPLS, EVPN, VXLAN, and 128-way ECMP. It provides internet-scale routing tables suitable for peering and data center interconnect applications.

Q: Is this switch suitable for spine or leaf deployment?
A: The DCS-7280CR2-60-DC-F is optimized for spine, core, super-spine, and data center interconnect roles due to its high-density 100G ports, deep buffers, and full routing capabilities. It can handle large routing tables and provide wire-speed performance for aggregation and core layers.
