Overview
The Cisco Nexus 93120TX switch (N9K-C93120TX) is a 2-RU, fixed-port switch designed for spine-leaf-APIC deployment in data centers. This switch has 96 fixed 1/10GBASE-T (copper) ports for APIC connections and six fixed 40-Gigabit QSFP+ (optical) ports for connections to spine switches. The chassis for this switch includes the following user-replaceable components:
-
Fan modules (two) with the following airflow choices:
-
Port-side intake airflow with burgundy coloring (N9K-C9300-FAN3)
-
Port-side exhaust airflow with blue coloring (N9K-C9300-FAN3-B)
-
-
Power supply modules (two—one for operations and one for redundancy [1+1]) with the following choices:
-
1200-W AC power supply with port-side intake airflow (burgundy coloring) (N9K-PAC-1200W)
-
1200-W AC power supply with port-side exhaust airflow (blue coloring) (N9K-PAC-1200W-B)
-
1200-W HVAC/HVDC power supply with dual-direction airflow (white coloring) (N9K-PUV-1200W)
Note
This power supply supported beginning with Release 11.2(1i) (February 2016).
-
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
Both power supplies should be the same type. Do not mix AC, DC, or HVAC/HVDC power supplies.
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.

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. |
