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.

  Table 3. Line Card Compatibility Matrix

  Line Card	Co-exist with X9736C-FX3
  X9716D-GX	Yes
  X9732C-EX	Yes
  X9732C-FX	Yes (not supported in ACI-Mode)
  X9736C-FX	Yes
  X9788TC-FX	Yes (not supported in ACI-Mode)

  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-X9736C-FX3, and N9K-X9736Q-FX 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.

  Fabric module 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.

• Fan trays (three) (N9K-C9508-FAN) or (N9K-C9508-FAN2) in slots FAN 1 to FAN 3 (numbered from left to right on the chassis)

• Power supplies (up to eight) in slots PS 1 to PS 8 (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.

The figure shows the hardware features seen from the front of the chassis.

The figure shows the hardware features seen from the rear of the chassis (one fan tray has been removed to show the fabric modules behind the fan trays).
