Overview
The Cisco Nexus 9332PQ switch (N9K-C9332PQ) is a 1 rack unit (RU) switch that supports 32 40-Gigabit QSFP+ ports, one 100/1000 network management ports, one RS-232 console port for setting the initial switch configuration, and two USB ports for saving or loading switch configurations.
The chassis for 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-30CFM-B)
-
Port-side exhaust fan module with blue coloring (NXA-FAN-30CFM-F)
-
-
Power supplies (two—one for operations and one for redundancy [1+1]) with the following choices:
-
650-W AC power supply with port-side intake airflow (burgundy coloring) (N9K-PAC-650W)
-
650-W AC power supply with port-side exhaust airflow (blue coloring) (N9K-PAC-650W-B)
-
1200-W HVAC/HVDC power supply with dual-direction airflow (white coloring) (N9K-PUV-1200W)
-
930-W DC power supply with port-side intake airflow (green coloring) (UCSC-PSU-930WDC)
-
930-W DC power supply with port-side exhaust airflow (gray coloring) (UCS-PSU-6332-DC)
Note
Do not mix AC and DC power supplies in the same chassis.
Note
All fan modules and power supplies must use the same airflow direction during operations. If you are using the 1200-W HVAC/HVDC power supply, the power supply automatically uses the same airflow direction as used by the other modules in the switch.
-
The switch supports the Fabric Extenders (FEXs) listed at https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/hw/interoperability/fexmatrix/fextables.html.

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 or port-side exhaust airflow. For port-side intake airflow, the fan and AC power supply modules have burgundy coloring (DC power supply modules have green coloring). For port-side exhaust airflow, the fan and AC power supplies have blue coloring (DC power supply modules have gray coloring). You can also order the 1200-W HVAC/HVDC power supply which has dual-direction airflow with white coloring. Dual-direction airflow modules automatically use the airflow direction of the other modules installed in the switch.
The fan and power supply modules are field replaceable and 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 of the 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 will automatically use the same airflow direction as the other modules in the switch. |
Caution |
If the switch has port-side intake airflow (burgundy coloring for fan modules), you must locate the ports in the cold aisle. If the switch has port-side exhaust airflow (blue coloring for fan modules), you must locate the ports in the hot aisle. If you locate the air intake in a hot aisle, the switch can overheat and shut down. |
