Description

The DCS-7504R3-FM is a switch fabric module from the Arista 7500R3 Series, built for the DCS-7504N 4-slot modular chassis. It suits large-scale data centre spine and core deployments, layer 2 and layer 3 cloud designs, EVPN/VXLAN overlays, internet peering and data centre interconnect.

Each module has an integrated fan and provides the switching fabric for the 7500R3 line cards. Six modules are required to populate fabric slots 1 to 6 in the 7504N chassis, which delivers 76.8 Tbps and 16 Bpps of throughput. Fabric redundancy uses graceful degradation, and the fan modules are N+1 redundant with front-to-rear airflow. The module is 2.5 x 8.5 x 10.25 in and weighs 7.5 lbs (3.4 kg). It draws power from the chassis and has no separate power input.

It works with the DCS-7504N chassis, 7500R3 line cards such as the DCS-7500R3-24P-LC, 24D-LC and 36CQ-LC, and the DCS-7500-SUP2 and SUP2-D supervisors. Fabric modules are generation-specific, so 7500R and 7500E fabric modules are not interchangeable, and the 7508R3-FM and 7512R3-FM are for other chassis. No licence is listed for the fabric module itself.

FAQs

Q: How many DCS-7504R3-FM modules does the 7504N chassis need?
A: Six. They populate fabric slots 1 to 6 in the DCS-7504N chassis.

Q: Does this fabric module need a licence?
A: No licence is listed for the fabric module itself. The chassis runs Arista EOS on the supervisor module.

Q: How is the fabric module powered?
A: It draws power from the chassis and has no separate power input. The 7504N uses up to four 3 kW PSUs (PWR-3KT-AC-RED, PWR-3KT-HV-RED or PWR-3K-DC-RED).

Q: What does it work with?
A: The DCS-7504N chassis, 7500R3 line cards (DCS-7500R3-24P-LC, 24D-LC, 36CQ-LC, 7500R3K-36CQ-LC and 7500R3K-48Y4D-LC) and DCS-7500-SUP2 or SUP2-D supervisors.

Q: Can I use 7500R or 7500E fabric modules, or the 7508R3-FM, instead?
A: No. Fabric modules are generation-specific, so 7500R and 7500E modules are not interchangeable, and the 7508R3-FM and 7512R3-FM are for other chassis.
