DCS-7508R-FM is a 7500R Series Fabric (integrated fan) Module designed for Arista 7508 and 7508N chassis and is required for fabric slots 1–6. The module integrates the cooling fan directly into the fabric module, consolidating thermal management with the fabric interconnect for the 7508 chassis. Arista's end-of-sale advisory lists DCS-7508R-FM as part of the 7500R family, with the replacement being DCS-7508R3-FM.
