Arista DCS-7808-FCM | Fabric Cooling Module for 7808 Chassis, Slot 6

Q: Which chassis models require the DCS-7808-FCM?
A: The DCS-7808-FCM is specifically designed for the Arista DCS-7808 chassis and must be installed in fabric slot 6. It is not compatible with the larger DCS-7812 or DCS-7816L chassis, which require their own respective fabric cooling modules.

Q: How many fan modules are included in the DCS-7808-FCM?
A: The DCS-7808-FCM includes 16 user-serviceable fan modules, all hot-swappable for maintenance without system downtime. The module supports graceful cooling degradation to maintain operation even if individual fans fail.

Q: Is the DCS-7808-FCM required for chassis operation?
A: Yes, the fabric cooling module is a required component for proper operation of the DCS-7808 chassis. It must be installed in fabric slot 6 to provide adequate cooling for fabric modules and ensure reliable performance of the modular switch system.

Q: Can the DCS-7808-FCM be replaced during operation?
A: Yes, the DCS-7808-FCM features hot-swappable fan modules that can be serviced individually during operation. However, replacement of the entire fabric cooling module should be performed according to Arista's recommended maintenance procedures to avoid thermal issues.

Q: What deployment scenarios is the DCS-7808-FCM suitable for?
A: The DCS-7808-FCM is designed for high-density data center environments, including AI spine networks, cloud infrastructure, and large-scale enterprise deployments where the DCS-7808 modular chassis provides scalable switching capacity with advanced fabric architectures.
