This switch chassis includes these modules:

• Supervisor modules (one or two)—one of these types in slots SUP 1 and SUP 2 (Modules 27 and 28 in reports) (numbered from left to right on the chassis)

• System controllers (two) (N9K-SC-A) in slots SC 1 and SC 2 (Modules 29 and 30 in reports) (numbered from left to right on the chassis)

• Line cards (up to 16) in slots LC 1 through LC 16 (Modules 1 and 16 in reports) (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 (Modules 21 and 26 in reports) (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.

  Table 1. Supported Fabric Modules and Line Cards

  Fabric Module	Fabric Modules Required for Maximum Bandwidth	Supported Line Cards

  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 or blank modules with power connectors (N9K-C9516-FM-Z) 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, see the Cisco Nexus 9500 Platform Line Cards and Fabric Modules Data Sheet.

• Fan trays (three) (N9K-C9516-FAN) in slots FAN 1 to FAN 3 (Modules 41 to 43 in reports) (numbered from left to right on the chassis)

• Power supplies (up to five with the combined power mode, up to six with the n+1 power redundancy mode, or up to ten with the n+n power redundancy mode) in slots PS 1 to PS 10 (Modules 31 to 40 in reports) (numbered from left to right on the chassis)

  • Cisco Nexus 9500 Series 3-kW AC power supply (N9K-PAC-3000W-B)

  • Cisco Nexus 9500 Series 3-kW Universal AC/DC power supply (N9K-PUV-3000W-B)

  • Cisco Nexus 9500 Series 3.15-kW Dual Input Universal AC/DC power supply (N9K-PUV2-3000W-B)

  • Cisco Nexus 9500 Series 3-kW (-48 V) DC power supply (N9K-PDC-3000W-B)

  Note	The switch can be powered by a mix of AC, DC, HVAC/HVDC power sources.

  All chassis slots are numbered from left to right or from top to bottom.
