Description

The Arista DCS-7280SR-48C6-R is a high-performance data center switch delivering 2.16 Tbps switching capacity with 48x 10GbE SFP+ ports and 6x 100GbE QSFP28 uplinks. Built on Arista EOS, this 1RU Layer 3 switch features deep packet buffers, low 3.8µs latency, and advanced automation capabilities ideal for spine-leaf architectures. The rear-to-front airflow design optimizes cooling in hot-aisle/cold-aisle data center environments.

FAQs

Q: What is the difference between the -R and -F airflow models?
A: The DCS-7280SR-48C6-R features rear-to-front (reverse) airflow where cool air enters from the port side and exhausts from the rear. The -F model has front-to-rear airflow. Choose based on your data center hot-aisle/cold-aisle configuration.

Q: Can the 100G QSFP28 ports be broken out to lower speeds?
A: Yes, each 100GbE QSFP28 port can be split into 4x 25GbE or 4x 10GbE connections using standard breakout cables, allowing up to 72 total 10G ports or flexible mixed configurations.

Q: What routing protocols does the 7280SR-48C6-R support?
A: The switch supports full Layer 3 routing including BGP, OSPF, MPLS, Segment Routing, VXLAN, EVPN, and 128-way ECMP. It can handle full internet routing tables with over 1 million IPv4 routes in hardware.

Q: Is this switch suitable for leaf-spine data center architectures?
A: Yes, the DCS-7280SR-48C6-R is designed as a cost-effective 10G leaf switch with 40/100G uplinks to spine switches. It supports VXLAN, MLAG, and CloudVision integration for modern data center fabrics.

Q: Does the switch include software licensing requirements?
A: The DCS-7280SR-48C6-R runs Arista EOS which includes comprehensive Layer 2 and Layer 3 features. Contact your Arista representative for current licensing models and CloudVision integration options.
