C9404-FAN Description
C9404-FAN is the Cisco Catalyst 9400 Series fan tray assembly for the Catalyst 9404R 4-slot chassis, a chassis-specific cooling FRU used to keep the modular switch operating within its environmental limits during normal service or fan-tray replacement. Cisco identifies C9404-FAN as the 4-slot Catalyst 9400 fan tray, confirms it uses eight individual fans in two rows of four, provides side-to-side airflow from right to left when viewed from the front, supports 640 CFM minimum airflow at 100 percent fan throttle, and can be installed or removed from either the front or rear of the chassis.

Application Scenarios
Use C9404-FAN when a Catalyst 9404R chassis needs the matching Cisco-listed fan tray assembly for maintenance or spare inventory.
For a new Catalyst 9404R configuration, verify that the fan tray line item matches the 4-slot chassis instead of the C9407-FAN or C9410-FAN used by larger chassis models.
When replacing the fan tray in a powered system, coordinate the service window with the network operations team and confirm the required service-mode procedure before the replacement starts.

- C9404-FAN is the correct fan tray SKU for the 4-slot Catalyst 9404R chassis; do not substitute it for the 7-slot or 10-slot chassis fan trays.
- The main technical differences across the three Catalyst 9400 fan tray SKUs are chassis fit, fan count, minimum airflow, and power and heat values.
- For a maintenance order line, treat the fan tray as a chassis-specific FRU and confirm whether the spare-ordering part number requires the equals suffix in the customer BOM.
- Review C9410-FAN alongside C9404-FAN for the adjacent technical comparison points. Related comparison SKUs: C9407-FAN.
Selection Guide
1. Choose this SKU for Catalyst 9404R only
Select C9404-FAN when the installed or quoted chassis is Cisco Catalyst 9404R and the requirement is the Cisco-listed fan tray assembly for that chassis.
2. Avoid cross-chassis substitution
Do not use this SKU for Catalyst 9407R or Catalyst 9410R projects, because Cisco lists separate fan tray models for those larger chassis.
3. Plan the replacement procedure before the window
If the chassis remains powered during replacement, confirm the service-mode timing and make sure the replacement unit is ready before the existing fan tray is removed.
4. Validate airflow and alarm context
Before purchase, confirm whether the issue is a failed fan tray, restricted airflow, seating problem, or chassis environmental alarm so the order matches the maintenance finding.
