Arista 7800R3 Fabric Module for 7804 Chassis

Arista DCS-7804R3-FM is the 7800R3 fabric module for the Arista 7804 chassis. It installs in fabric slots 1-6, and a chassis uses 6 modules.

Each module draws 180 W typical and 248 W at maximum. Multiply by the module count when you plan the power budget for the chassis, since all six sit in the system together.

Fabric modules connect the line cards to each other inside the chassis. They are bought either to complete a new 7804 build or to replace a failed module and restore full fabric capacity. The part is listed for the 7804 only, so check your chassis model before ordering.

DCS-7804R3-FM is offered New and Refurbished, each with your choice of 1 year or 3 years of warranty. Tell us the number of modules you need in your request, and we will reply with pricing and lead time.
