Description

This Arista 7500R3 Series fabric module is a hot-swappable chassis component for the 7512N 12-slot modular data centre switch. It carries an integrated fan module and forms part of the cell-based switching fabric that links the line cards. It suits spine and core deployments in large data centre, cloud and universal spine networks that need lossless, deep-buffer, high-density 100G and 400G switching.

The DCS-7512R3-FM is required for fabric slots 1-6, so six modules populate a fully equipped 7512N chassis. Redundancy is graceful degradation: if a fabric module fails, the chassis keeps forwarding with reduced fabric bandwidth. The fabric is part of a fully scheduled architecture using Virtual Output Queues and deep buffers, and the platform runs Arista EOS.

This module works with the DCS-7512N chassis and 7500R3 Series line cards. The 7508 and 7504 chassis use separate fabric module part numbers, DCS-7508R3-FM and DCS-7504R3-FM, so confirm the chassis model before ordering. No licence is required for the module itself. Software features follow the EOS licensing of the host chassis.

FAQs

Q: Does this fabric module need a licence?
A: No licence is required for the fabric module itself. Software features are governed by the Arista EOS licensing of the host chassis.

Q: How many fabric modules does a 7512N chassis need?
A: Six modules are required to populate fabric slots 1-6 in the 7512N chassis.

Q: Will it work in a 7508 or 7504 chassis?
A: No. The 7508 and 7504 chassis use separate fabric module part numbers, DCS-7508R3-FM and DCS-7504R3-FM. The DCS-7512R3-FM is for the 7512N chassis.

Q: Where does the module draw its power?
A: It draws power from the 7512N chassis power supplies. The fan is integrated into the module, so no separate fan module is needed for its slot.

Q: What happens if one fabric module fails?
A: Redundancy is graceful degradation. The chassis keeps forwarding traffic, with reduced fabric bandwidth until the module is replaced.
