The Arista 7280SR3K-48YC8 is built for enterprise data centre leaf and aggregation fabrics that need scalable routed access and cleaner network boundaries. Its Layer 3 design with dynamic routing and hot-swappable PSUs helps extend fabric life while maintaining resilient service as routes and policies grow.
Guide price: Price range: £14,850.00 through £14,950.00 Ex. VAT
As routed access layers grow denser, infrastructure teams need to carry more tenants, policies and routes without changing the server-facing design.
The Arista 7280SR3K-48YC8 is a switch router for larger routed fabrics and aggregation layers, built for production environments that need 25GbE server connectivity with additional uplink capacity.
Its 48×SFP28 ports and 8×QSFP28 uplinks provide a familiar rack profile, while the 4000 Gbps switching capacity supports heavier east-west and north-south demands.
This makes it easier to keep the same access model as workloads expand, while preserving room for segmentation, multi-site connectivity and control-plane headroom.
With hot-swappable PSUs, the Arista 7280SR3K-48YC8 also fits maintenance windows and resilient operations where uptime and service continuity matter.

The Arista 7280SR3K-48YC8 is a data center switching platform for high-density leaf and spine deployments, providing a scalable foundation for modern network fabrics and operational consistency.
Leaf-Spine Uplink Design
The platform combines 48×SFP28 and 8×QSFP28 ports to support dense access and aggregation in fabric-oriented designs.
100G Fabric Headroom
Maximum port speed of 100G supports high-bandwidth uplinks where aggregation and east-west traffic demand higher throughput.
Converged Port Mix
A mixed 48×SFP28 and 8×QSFP28 architecture enables structured endpoint connectivity alongside higher-speed fabric interconnects.
Large-Scale Switching Core
Switching capacity of 4000 Gbps provides the throughput needed to sustain demanding data center traffic patterns.
Fabric Consistency
The switch is designed for predictable operation within standardized data center network topologies.
Deployment Flexibility
Its port architecture supports both access-layer attachment and aggregation-layer uplinks in the same platform.
Throughput-Oriented Design
High switching capacity and 100G uplink support help maintain performance as network demand increases.
If you are planning high-density data center interconnects or fabric upgrades, our Arista experts can help align the 7280SR3K-48YC8 with your throughput and topology requirements.

The Arista 7280SR3K-48YC8 is aimed at high-scale 25GbE leaf and aggregation deployments where route tables, VRFs and policy growth matter as much as server port density. It fits shared infrastructure that must stay physically stable while network segmentation expands.
In colocation and enterprise data centres, this switch fits racks that keep the same 48x25GbE server profile but need more tenants and more routes. It helps delay fabric redesign as connectivity demands rise.
Finance teams can place it in racks carrying trading-support, analytics, payments and compliance systems where separation is often the real constraint. The extra control-plane headroom supports growing policy and route demands without changing server access design.
For energy and utilities, it suits operational data-centre racks bringing together telemetry, control, analytics and corporate services. Larger scale at the leaf helps keep OT and business networks isolated while still sharing a routed access layer.
Software development environments use it for multi-team private cloud, CI/CD and container clusters where each group needs clean network boundaries. It supports more routed service networks on shared infrastructure without forcing separate physical fabrics.
In telecoms, the switch fits NFV, MEC and packet-core racks where service chains, VRFs and lab domains grow quickly. It preserves 25GbE appliance density while absorbing heavier routing and segmentation requirements at the edge.
We can help design and deploy the Arista 7280SR3K-48YC8 for data centres, finance, energy and utilities, software development and telecoms, with practical support for topology, segmentation and rollout planning.
