Overview
The Cisco Nexus 9316D-GX switch (N9K-C9316D-GX) is a 1-RU, fixed-port spine switch designed for spine-leaf-ACI deployment in data centers. This switch has 16 x 400/100-Gbps QSFP-DD ports.
To determine which transceivers, adapters, and cables this switch supports, see the Cisco Transceiver Modules Compatibility Information document.
This switch includes the following user-replaceable components:
-
Fan modules (six) with the following airflow choices:
-
Port-side exhaust airflow with blue coloring (NXA-FAN-35CFM-PE)
-
Port-side intake airflow with burgundy coloring (NXA-FAN-35CFM-PI)

Power supply modules (two—One for operations and one for redundancy [1+1]) with the following choices:
-
1100-W AC power supply with port-side exhaust airflow (blue coloring) (NXA-PAC-1100W-PE2)
-
1100-W AC power supply with port-side intake airflow (burgundy coloring) (NXA-PAC-1100W-PI2)
-
1100-W HVAC/HVDC power supply with port-side exhaust airflow (blue coloring) (NXA-PHV-1100W-PE)
-
1100-W HVAC/HVDC power supply with port-side intake airflow (burgundy coloring) (NXA-PHV-1100W-PI)
-
1100-W DC power supply with port-side exhaust airflow (blue coloring) (NXA-PDC-1100W-PE)
-
1100-W DC power supply with port-side intake airflow (burgundy coloring) (NXA-PDC-1100W-PI)
Note
Both power supplies use the same type of power source. Do not mix AC and DC power sources.
Note
All fan modules and power supplies must use the same airflow direction during operations.

USB port that is used for saving or copying functions. |
Note |
USB support is limited to USB 2.0 devices that use less than 2.5 W (less than 0.5 A inclusive of surge current). There is no support for devices, such as external hard drives, that instantaneously draw more than 0.5 A. |
Depending on whether you plan to position the ports in a hot or cold aisle, you can order the fan and power supply modules with port-side intake (red colored) or port-side exhaust (blue colored) airflow. All the power supply and fan modules must have the same coloring.
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 operating. If you have only one power supply that operational, you can install the replacement power supply in the open slot before removing the original power supply.
Note |
All the fan and power supply modules must have the same direction of airflow. Otherwise, the switch can overheat and shut down. |
Caution |
If the switch has port-side intake airflow (burgundy coloring for fan modules), you must orient the ports in the cold aisle. If the switch has port-side exhaust airflow (blue coloring for fan modules), you must orient the ports in the hot aisle. If you orient the air intake in a hot aisle, the switch can overheat and shut down. |
