This switch chassis includes the following modules:

• Supervisor modules (one or two)—one of the following 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 (numbered from left to right on the chassis)

  See the following 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
  N9K-C9516-FM	4	N9K-X9736PQ
  N9K-C9516-FM-E2	4 5 5	N9K-X9732C-EX N9K-X9736C-FX N9K-X9736Q-FX

  	X9736PQ	X9736Q-FX	X9732C-EX	X9736C-FX
  Fabric modules
  C9516-FM-E-E2	No	Yes	Yes	Yes

  Note

  The fabric modules must be installed in specific slots as follows (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

  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 in order 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, you must make sure that they have a blank module (N9K-C9516-FM-CV) installed to preserve the designed airflow.

  Note	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 (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 (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.

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

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

The following 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).
