Overview
The Cisco Nexus 9332PQ switch (N9K-C9332PQ) is a 1 rack unit (RU) switch that supports 26 40-Gigabit downlink ports, 6 40-Gigabit uplink 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:
-
Power supplies (two—one for operations and one for redundancy [1+1]) with the following choices:
-
650-W port-side intake AC power supply with burgundy coloring (N9K-PAC-650W)
-
650-W port-side exhaust AC power supply with blue coloring (N9K-PAC-650W-B)
-
930-W port-side intake DC power supply with green coloring (UCSC-PSU-930WDC)
Note
You can use 650-W AC power supplies and 930-W DC power supplies interchangeably so long as they have the same direction of airflow (if DC power supplies are used, all of the fan and power supply modules must have port-side intake airflow).

This switch supports connections to the following Fabric Extenders (FEXs):

Depending on whether you plan to position the ports in a cold or hot aisle, you can order the fan and power supplies with port-side intake or port-side exhaust airflow (the DC power supplies have port-side intake airflow only). For port-side intake airflow, the fan and AC power supply modules have burgundy coloring, and DC power supplies have green coloring. For port-side exhaust airflow, the fan and AC power supply modules have blue coloring.
Note | You can order AC or DC power supplies for the chassis. You can use two AC power supplies, two DC power supplies, or mix one AC power supply with one DC power supply. |
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.
CAUTION: If the switch has port-side intake airflow (burgundy coloring for the fan and AC power supply modules, and green coloring for DC power supply modules), you must locate the ports in the cold aisle. If the switch has port-side exhaust airflow (blue coloring for fan and AC power supply 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.
