Overview
This switch chassis includes these modules:
-
Supervisor modules (one or two) in slots SUP 1 and SUP 2 (reported as modules 27 and 28) (numbered from left to right on the chassis)
-
System controllers (two) (N9K-SC-A) in slots SC 1 and SC 2 (reported as modules 29 and 30) (numbered from left to right on the chassis)
-
Line cards (up to eight) in slots LC 1 to LC 8 (reported as modules 1 to 8) (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.
-
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 compatibility of fabric modules, fans, and fabric module blanks or fan power cards.

Note
You can see the status of only 1 to 30 modules.
switch# sh module ? <CR> <1-30> Enter module number
Note
All of the fabric modules in a modular switch must be of the same type.
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 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
This information applies to the fabric modules:
-
When using FM-G fabric modules, any empty fabric module slots should be filled with N9K-C9508-FAN-PWR cards.
-
When using any fabric modules other than N9K-C9508-FM-G, any empty slots should be filled with N9K-C9508-FM-CV cards.
-
When using N9K-C9508-FM-R2, do not leave any fabric module slots empty.
-
For more information about line card and fabric module compatibility, see the Cisco Nexus 9500 Platform Line Cards and Fabric Modules Data Sheet.
