Arista DCS-7508R3-FM 7500R3 Series Switch Fabric Module for 7508N Chassis

The DCS-7508R3-FM is the 7500R3 fabric module for the DCS-7508N chassis, which becomes the 7508R3 when fitted with this fabric. Six are required, one in each of fabric slots 1 to 6.

The modules run active-active and are hot-swap, with graceful degradation if one is removed or fails. That allows a module to be replaced while the chassis keeps forwarding traffic at reduced fabric capacity.

Each module has an integrated fan that follows the chassis airflow, front-to-back (port-side intake). Match the power supplies to this direction and keep the line card ports on the cold aisle side of the rack.

This fabric is intended for 7500R3 line cards such as the 7500R3K-36CQ-LC. Arista lists it for the DCS-7508N chassis only. Power draw is 225 W typical and 380 W maximum per module. Each module weighs 13.25 lb and measures 2.5 x 14 x 10.25 inches (H x W x D).

Line cards and fabric modules are hot-swappable in Arista modular chassis, so you can add or replace one without powering the chassis down.

Keep blank covers in any empty slots so the chassis airflow stays balanced.

For the rest of the chassis build, NetworkTigers also lists the DCS-7500-SUP2 supervisor module and the DCS-7500-SUP2-D supervisor module.

This seller refurbished DCS-7508R3-FM is tested, working, and covered by the NetworkTigers one-year warranty.
