FAQs

Q: Is the DCS-7816L-FCM required for all DCS-7816L chassis deployments?
A: Yes, the DCS-7816L-FCM is a required component for the DCS-7816L chassis and must be installed in fabric slot 6 to provide cooling for the fabric modules and ensure proper system operation.

Q: Can the fan modules be replaced while the system is running?
A: Yes, all 16 fan modules are user-serviceable and support hot-swap capability, allowing for maintenance and replacement without system downtime.

Q: What happens if one or more fans fail in the DCS-7816L-FCM?
A: The module supports graceful cooling degradation, meaning the system can continue to operate with reduced fan capacity while alerting administrators to the failure. However, failed fans should be replaced promptly to maintain optimal cooling performance.

Q: Is this module compatible with older 7800R3 Series chassis?
A: The DCS-7816L-FCM is specifically designed for 7800R4 Series deployments. For 7800R3 Series chassis, different fabric cooling modules are required. Always verify compatibility with your specific chassis model.

Q: What is included with the DCS-7816L-FCM when purchased?
A: The module includes the fabric cooling assembly with 16 integrated fan modules pre-installed. Bundle configurations typically include the FCM along with the chassis, fabric modules, supervisors, and power supplies as part of a complete system.
