Description

The Arista 7800R4 Fabric Cooling Module (FCM) is a mandatory chassis component for the 7816L 16-slot spine chassis, occupying fabric slot 6 to complete the six-slot fabric module bay configuration. Designed for hyperscale AI/ML, HPC, and data centre spine deployments, this hot-swappable module ensures continuous airflow management across the fabric interconnect, maintaining system redundancy and thermal integrity without requiring a service window.

As part of the 7800R4 Series modular architecture, the DCS-7816L-FCM supports front-to-rear optimised airflow and is compatible with both AC and DC power configurations. It enables full chassis operability alongside five FM-R4 fabric modules, and supports upgrade paths from 7800R3 to 7800R4 specifications.

FAQs

Q: What is the DCS-7816L-FCM and why is it required?
A: The DCS-7816L-FCM is a Fabric Cooling Module for the Arista 7816L chassis. It occupies fabric slot 6 and is mandatory for completing the chassis fabric bay — without it, the 7816L cannot operate at full capacity. It provides dedicated cooling for the fabric interconnect zone.

Q: Which chassis is this module compatible with?
A: This module is specifically designed for the Arista 7816L chassis, a 16-slot, 32RU spine platform used in high-density AI/ML, HPC, and data centre environments. It is not interchangeable with other Arista chassis form factors.

Q: Can this module be replaced without powering down the chassis?
A: Yes. The DCS-7816L-FCM is fully hot-swappable, allowing replacement or maintenance during live operation to maintain business-critical availability and system redundancy without scheduling downtime.

Q: How many fabric modules does the 7816L chassis support in total?
A: The 7816L chassis supports 6 fabric module slots in total — 5 slots for FM-R4 fabric modules and 1 slot (slot 6) for the FCM cooling module. All 6 slots must be populated for proper operation.

Q: Is this module part of the 7800R4 upgrade path?
A: Yes. The DCS-7816L-FCM is part of the 7800R4 Series ecosystem and supports upgrade configurations from 7800R3 to 7800R4 specifications, enabling customers to scale their spine infrastructure for next-generation AI and data centre workloads.

Q: Can I purchase the DCS-7816L-FCM in Australia through IP Trading?
A: Yes. IP Trading supplies authentic Arista hardware to Australian businesses, including data centre chassis accessories like the DCS-7816L-FCM. Visit iptrading.com.au to place your order or contact the team for availability and volume pricing.
