Description

The Arista 7500E Fabric Module is the Fabric-E module with an integrated fan assembly for the 8-slot 7508E modular data centre switch chassis. It interconnects every line card in the chassis and is aimed at large data centre spine and core deployments built on the Arista 7500E Series, where the 7508E chassis supports up to 30 Tbps of throughput.

Each module provides 5.12 Tbps of non-blocking fabric capacity and operates in a 5+1 redundant configuration across the six fabric module slots in the chassis. Fabric modules are always active-active with N+1 redundancy, and typical power draw is 155W with a 195W maximum per module. The fan assembly is integrated, giving flexible and redundant cooling. This SKU is specific to the 8-slot 7508E chassis.

It works with the 7500E line cards (12CQ, 12CM, 36Q, 6C2, 72S, 48S and 48T) and the 7500E-SUP supervisor. It is not interchangeable with DCS-7504E-FM, which is for the 4-slot chassis. System power comes from the chassis PWR-2900AC power supplies.
