Every WhaleyComm unit is professionally tested, reset to factory defaults, and certified by our in-house engineers — the same standard trusted by 5,000+ organisations across 25 years. Not a refurb marketplace. A certified lifecycle partner.
Tested to factory specification. Backed by 25 years of enterprise trust.
The Arista DCS-7504R-FM Fabric Module is an essential internal component for the Arista 7504 and 7504N modular chassis systems. Fabric modules serve as the high-speed backplane interconnect between line cards and supervisor modules within the chassis, enabling consistent, low-latency data forwarding across all installed slots.Available from WhaleyComm in Refurbished condition, the DCS-7504R-FM provides a reliable and budget-conscious option for network operators looking to deploy, expand, or maintain their Arista 7500R-series chassis environments. Each Refurbished unit is inspected and verified for functionality before shipment.
The 7504 chassis is widely deployed in large-scale enterprise core and data center aggregation layers, and maintaining proper fabric redundancy is critical to sustaining non-blocking performance. The DCS-7504R-FM is specifically engineered for the 7504 and 7504N form factor and is not interchangeable with other chassis variants in the 7500 family.
Whether you are building out a new deployment or replacing a failed fabric module in an existing production environment, WhaleyComm's Refurbished DCS-7504R-FM offers a cost-effective solution without sacrificing compatibility or reliability.

Ideal Use Cases
Data Center Core Fabric Maintenance
Replace a failed or degraded fabric module in a production Arista 7504 chassis to restore full switching fabric capacity. The Refurbished DCS-7504R-FM provides a cost-effective spare for minimizing unplanned downtime.
Fabric Redundancy Expansion
Add fabric redundancy to an existing Arista 7504 or 7504N deployment to improve resilience against hardware failures. Ensuring multiple fabric modules are seated supports continuous, non-blocking operation across all line cards.
Greenfield Campus or Data Center Build-Out
Equip a new Arista 7504 chassis deployment with the required fabric modules at a reduced capital cost using Refurbished hardware. This approach helps organizations meet performance requirements while managing procurement budgets effectively.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The DCS-7504R-FM is a fabric module designed specifically for the Arista 7504 and 7504N chassis platforms. It is not confirmed compatible with other members of the 7500 chassis family without independent verification.
A fabric module provides the high-speed internal switching fabric interconnect between line cards and the supervisor within the chassis. It is essential for enabling full-capacity, low-latency forwarding across all installed slots.
The WhaleyComm DCS-7504R-FM is sold in Refurbished condition, meaning it has been previously deployed and has undergone basic functionality inspection before being made available for resale. It offers a reliable, cost-effective alternative to new hardware.
The exact number of fabric module slots in the Arista 7504 chassis should be verified against the official Arista hardware installation guide, as WhaleyComm recommends confirming slot count and redundancy requirements directly with Arista documentation before purchasing.
