This switch chassis includes:

• 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 (Modules 29 and 30 in reports) (numbered from left to right on the chassis)

• Line cards (up to four) in slots LC 1 to LC 4 (Modules 1 through 4 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.

• 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 required for maximum bandwidth.

  Prior to ACI Release 6.1.2, N9K-9504-FM-G Fabric Module works with both FX + GX line card modules. Release 6.1(2) added the EX line card module.

  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 must be 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. All of the fabric modules in a modular switch must be of the same type. When using FM-G fabric modules, any empty slots should be filled with FAN-PWR modules (N9K-C9504-FAN-PWR). When using N9K-C9504-FM or N9K-C9504-FM-E fabric modules, any empty slots should be filled with N9K-C9504-FM-CV. 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-C9504-FAN) or (N9K-9504-FAN2) 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 two with the combined power mode, up to three with n+1 power redundancy mode, or up to four with the n+n power redundancy mode) in slots PS 1 to PS 4 (Modules 33 to 36 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, and HVAC/HVDC power sources. All chassis slots are numbered from left to right or from top to bottom.

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

This 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).
