Overview

Overview

The Cisco Nexus 93180LC-EX switch (N9K-C93180LC-EX) is a 1-RU, fixed-port switch designed for spine-leaf-APIC deployment in data centers. This switch has 24 downlink QSFP+ ports that you can configure to work as 40- or 50-Gigabit ports, and it has six fixed uplink QSFP28 ports that you can configure to work as 40- or 100-Gigabit ports. The chassis for this switch includes the following user-replaceable components:

  • Fan modules (four) with the following airflow choices:

    • Port-side intake airflow with burgundy coloring (NXA-FAN-30CFM-B)

    • Port-side exhaust airflow with blue coloring (NXA-FAN-30CFM-F)

  • Power supply modules (two—one for operations and one for redundancy [1+1]) with the following choices (do not mix AC and DC power sources and do not mix airflow directions):

    • 500-W AC power supply with port-side intake airflow (burgundy coloring) (NXA-PAC-500W-PI)

    • 500-W AC power supply with port-side exhaust airflow (blue coloring) (NXA-PAC-500W-PE)

    • 930-W DC power supply with port-side exhaust airflow (blue coloring) (NXA-PDC-930W-PE)

    • 930-W DC power supply with port-side intake airflow (burgundy coloring) (NXA-PDC-930W-PI)

    • 1200-W HVAC/HVDC power supply with dual-direction airflow (white coloring) (N9K-PUV-1200W)


    Note

    If you are using the 1200-W HVAC/HVDC power supply, the power supply automatically uses the same airflow direction as used by the fan modules installed in the same switch.

The following figure shows the hardware features seen from the port side of the chassis.

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). Devices, such as external hard drives, that instantaneously draw more than 0.5 A are not supported.

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. To determine the airflow direction of the modules installed in your switch, see the following table.

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.
