Overview
This switch chassis includes these modules:
-
Supervisor modules (one or two)—one of these types in slots SUP 1 and SUP 2 (numbered from left to right on the chassis)
-
System controllers (two) (N9K-SC-A) in slots SC 1 and SC 2 (numbered from left to right on the chassis)
-
Line cards (up to 16) in slots LC 1 through LC 16 (numbered from top to bottom on the chassis) supported by the same type of fabric module
For compatibility information, please refer to the Line Card and Fabric Module Compatibility data sheets.
Note
Do not mix ACI-mode line cards with NX-OS mode line cards in the same switch.
Note
The N9K-X9716D-GX line card is not compatible with this switch.
-
Fabric modules in slots FM 1 to FM 6 (are numbered from left to right on the chassis)
Note
Fabric modules in slots FM 1 to FM 6 (numbered from left to right on the chassis) are referred to as slot 21 to slot 26 in the system report, such as show modules CLI output.
See the table for the required fabric module types and quantities that are required for maximum bandwidth.

Note
The fabric modules must be installed in specific slots. Installing fabric modules in other slots can cause a module mismatch condition.
-
For three modules, they must be in slots FM 2, FM 4, and FM 6.
-
For four modules, they must be in slots FM2, FM 3, FM 4, and FM 6.
-
For five modules, they can be in slots FM 1, FM 2, FM 3, FM 4, and FM 6. Alternatively, they can be in Slots FM 2, FM 3, FM 4, FM 5, and FM 6.
-
For five FM-E or FM-E2 modules, they must be in Slots FM 2, FM 3, FM 4, FM 5, and FM 6.
-
For six modules, they are in slots FM 1, FM 2, FM 3, FM 4, FM 5, and FM 6.
-
FM 5 (slot number 25) will only work with N9K-X9736C-FX, N9K-X9736Q-FX, and N9K-X9736C-FX3 and not with other line card modules.
Note
All of the fabric modules in a modular switch must be of the same type.
Note
Fabric slots FM 2, FM 4, or FM 6 must be filled with functioning fabric modules to provide power to the fan trays covering those modules.
If fabric slots FM 1, FM 3, or FM 5 are not filled with a fabric module, verify that they have a blank module (N9K-C9516-FM-CV) installed to preserve the designed airflow.
For more information about Line Card and Fabric Module compatibility, refer to the Cisco N9500 Platform Line Cards and Fabric Modules Data Sheet.
