C9404-FAN Description
C9404-FAN is a Cisco Catalyst 9400 Series fan tray assembly for the Catalyst 9404R chassis, used to cool the 4-slot modular switch chassis and support environmental monitoring.
This fan tray is chassis-specific: Cisco lists C9404-FAN for the Catalyst 9404R, while the larger Catalyst 9407R and 9410R chassis use different fan tray SKUs. It has eight individual fans in two rows of four and supports side-to-side airflow across installed cards.
Use C9404-FAN when a Catalyst 9404R build or maintenance plan needs the documented fan tray assembly. Before quoting, confirm the installed chassis model, whether the order is for a new configuration or spare replacement, the service window, and current stock and warranty support with Layer23-Switch.

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 quote, 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.
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.
Ordering Checklist

Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Exact SKU |
C9404-FAN |
Confirms the fan tray is for the Catalyst 9404R chassis |
|

Eight-fan chassis cooling assembly |
Confirms the part is a cooling FRU, not a line card or power supply |
|
Service Procedure |
Powered replacement timing and service-mode readiness |
Reduces risk during a live maintenance window |
|
