The Cisco Nexus 9364D-GX2A switch (N9K-C9364D-GX2A) is a 2-rack unit (RU), fixed-port switch designed for spine-leaf-APIC deployment in data centers.

This switch includes the following ports:

• 400-Gigabit QSFP-DD ports (64)

• 10-Gigabit SFP+ ports (2)

• Management ports (one RJ-45 port and one SFP port)

• Console port

• USB port

Note	Use dust covers (NXA-ACC-QDD-DC) for unused ports. This protects the connectors and helps divert airflow for thermal dispensation.

Default port-profile information for this switch:

• Default port profile (Leaf): 48 downlinks and 16 fabric links + 2x1/10G downlinks

Leaf/Spine role considerations:

• This default role of the switch is as a spine switch.

• Use the default fabric links (49-64) for initial switch discovery via another switch.

• To change the switch from the default role: the node appears as a discovered device in the fabric inventory view, set the role of the switch (spine or leaf), and the switch automatically reboots to come up in the configured role.

• If you connect a default spine (i.e., a dual role switch that by default is a spine, such as Nexus 9316D-GX) directly to an APIC, the change of the role to leaf is performed automatically by APIC, as well as the reboot. After that, the node appears in “Nodes pending registration.” Register the node.

This switch includes the following user-replaceable components:

• Fan modules (four) with the following airflow choices:

  • Port-side intake fan module with burgundy coloring (NXA-FAN-160CFM2-PI)

    Note	If a fan fails, the other fans are automatically increased to 100% capacity to compensate. If two fans fail, then multi-fan failure policy kicks in, the switch will issue a warning, and power down in 2 minutes.

• Power supply modules (two—One for operations and one for redundancy [1+1]) with the following choices:

  • 3200-W port-side intake AC/HVDC power supply with burgundy coloring (NXA-PAC-3200W-PI)

  • 3200-W port-side intake DC/HVDC power supply with burgundy coloring (NXA-PDC-3200W-PI)

  Note	Both power supplies are the same type. Do not mix AC and DC power supplies.

The following figure shows the switch features on the port side of the chassis.

To determine which transceivers, adapters, and cables are support this switch, see the Cisco Transceiver Modules Compatibility Information document.

The fan and power supply modules are field replaceable. You can replace one fan module or one power supply module during operations, as long as the other modules are installed and operating. If you have only one power supply installed, you can install the replacement power supply in the open slot before removing the original power supply.

Note	All fan and power supply modules must have the same direction of airflow, or the switch can overheat and shut down. If you are installing a dual-direction power supply, that module automatically uses the same airflow direction as the other modules in the switch.

Caution

The switch has port-side intake airflow (burgundy coloring for fan modules), so you must locate the ports in the cold aisle. If you locate the air intake in a hot aisle, the switch can overheat and shut down.

Use dust covers (NXA-ACC-QDD-DC) for unused ports. This protects the connectors and helps divert airflow for thermal dispensation.
