Arista Networks DCS-7500-SUP2 Supervisor Module

Arista DCS-7500-SUP2 is the Supervisor-2 module for Arista's 7500 Series data center switches, offered here as a spare part for field replacement and rapid recovery. As the supervisor, it provides the control-plane processing that manages the switch's software and overall system operation within compatible 7500-series chassis. The DCS-7500-SUP2 is the second-generation supervisor card for the 7500 family and is documented on Arista's data sheets and advisories as the spare option for 7500 Series deployments; end-of-sale notices show replacement paths to older supervisor models such as DCS-7500E-SUP, underscoring a clear upgrade/downgrade lineage in the 7500 platform. This spare is designed for use with 7500R3-series switches, enabling quick restoration of supervisory functionality if the primary supervisor becomes unavailable. When planning a spare, ensure you are ordering the correct generation for your chassis and align with Arista's published compatibility guidance to minimize downtime during maintenance.
