N9K-C9504-FAN Description
N9K-C9504-FAN is a Cisco Nexus 9500 Series fan tray for the Nexus 9504 chassis, used in the three FAN 1 to FAN 3 positions that cool the 4-slot modular switch.
This fan tray belongs in Nexus 9504 builds using the N9K-C9504-FM, N9K-C9504-FM-E, N9K-C9504-FM-R, or N9K-C9504-FM-S fabric module path. The main ordering difference is the 400G FM-G path: Cisco documents N9K-C9504-FAN2 for N9K-C9504-FM-G fabric modules, with FAN-PWR filler hardware for empty FM-G slots.
Procurement should verify the installed chassis, fabric module family, current fan tray count, service-window plan, and empty fabric-slot filler before the line item is quoted. The fan tray is hot-swappable, but Cisco replacement guidance still favors having the replacement unit ready before a running chassis fan tray is removed.

Application Scenarios
N9K-C9504-FAN fits a Nexus 9504 maintenance plan when the installed chassis uses the Cisco-listed fan tray type for the non-FM-G fabric module path. Match the replacement to the chassis and fabric family before scheduling the swap.
This fan tray is the matching choice for Nexus 9504 systems built around N9K-C9504-FM, FM-E, FM-R, or FM-S fabric modules. It should not be treated as the fan tray for the FM-G 400G fabric path.
The fan tray also covers rear fabric module access, so a fabric replacement may require removing the tray above the fabric slot. Keep the service plan aligned with Cisco guidance for removing one fan tray at a time during live operation.

Cisco ordering description |
Fan Tray for Cisco Nexus 9504 Chassis |
Nexus 9500 4-slot chassis 400G cloud scale fan tray |
- In a N9K-C9504-FAN vs N9K-C9504-FAN2 comparison, the key difference is the fabric module family: N9K-C9504-FAN aligns with FM, FM-E, FM-R, and FM-S, while N9K-C9504-FAN2 aligns with FM-G.
- The N9K-C9504-FAN difference from N9K-C9504-FAN2 also affects empty fabric-slot hardware, because Cisco lists N9K-C9504-FM-CV for the matching non-FM-G path and N9K-C9504-FAN-PWR for the FM-G path.
- For buyers comparing which model to choose, both fan trays are for the Nexus 9504 chassis, so the order check should start with the fabric module type rather than the chassis name alone.
Selection Guide
1. Match the fan tray to the Nexus 9504 fabric path
Choose N9K-C9504-FAN when the Nexus 9504 bill of materials or installed chassis uses N9K-C9504-FM, FM-E, FM-R, or FM-S fabric modules.
2. Select FAN2 for FM-G designs
Select N9K-C9504-FAN2 instead when the project uses N9K-C9504-FM-G fabric modules, because Cisco documents the FM-G path with the Generation 2 fan tray.
3. Check empty fabric slots before the quote
Confirm whether empty fabric slots need N9K-C9504-FM-CV or N9K-C9504-FAN-PWR, since the correct filler hardware changes with the fabric module path.
4. Align replacement timing with Cisco service guidance
Keep only one fan tray removed during live replacement and have the new tray ready, because Cisco guidance warns against extended or multiple fan tray removal during operation.
