Overview
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 |
Dust covers (NXA-ACC-QDD-DC) are suggested for unused ports, to protect the connectors and help 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 switch's default role is as a spine switch.
-
The default fabric links (49-64) must be used for initial switch discovery via another switch.
-
To change the switch from the default role, you must proceed as follows: the node appears as a discovered device in the fabric inventory view, you must set the role of the switch (spine or leaf) and the switch automatically goes for reboot 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” and you need to register the node.
This switch includes the following high power optics and MACsec:
-
16 ports of MACsec with no ports of 20-W optics
-
8 ports of MACsec with 8 ports of 20-W optics
-
No ports of MACsec with 16 ports of 20-W optics
Note
For this switch, 20-W optics can go in any of the 32 odd numbered QSFP-DD ports.
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.

Grounding pad |
The fan and power supply modules are field replaceable. You can replace one fan module or one power supply module during operations so 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. Otherwise, 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. |
