CHAPTER 1
Overview
•Overview, on page 1
Overview
The Cisco Nexus 9336C-FX2-E switch (N9K-C9336C-FX2-E) is a 1-rack mount unit (RU), fixed-port switch
designed for spine-leaf-APIC deployment in data centers.
This switch has 36 40/100-Gigabit QSFP28 ports. Ports 31-36 are default fabric links (The last 2 ports 35-36
are reserved for fabric links). Downlink ports, 1-30 by default, support 4x10/4x25-Gigabit breakout. Up to
34 breakout ports are supported, ports 31-34 are convert-able to downlink ports. All ports support 10-Gigabit
with a QSA adapter (CVR-QSF-SFP10G). Ports 7-32 support 1-Gigabit with QSA adapter.
To determine which transceivers, adapters, and cables this switch supports, see the Cisco Transceiver Modules
Compatibility Information document.
This switch has the following ports:
• 36 40/100-Gigabit QSFP28 ports
• Two management ports (one 10/100/1000BASE-T port and one SFP port)
• One console port (RS-232)
• One USB port
This switch includes the following user-replaceable components:
• Fan modules (6) with the following airflow choices:
• Port-side exhaust fan module with blue coloring (NXA-FAN-35CFM-PE)
• Port-side intake fan module with burgundy coloring (NXA-FAN-35CFM-PI)
• Port-side exhaust fan module with blue coloring (NXA-SFAN-35CFM-PE)
• Port-side intake fan module with burgundy coloring (NXA-SFAN-35CFM-PI)
To enable or disable displaying the serial number of the NXA-SFAN-35CFM-PI
or NXA-SFAN-35CFM-PE fan, enter the [no]hardware fan-sprom command.

Each fan module has two rotors. The switch can function normally if one rotor
inside the any one fan module fails. In case of more than one rotor failure, the
switch will issue a warning and power down in 2 minute.
Note
• Power supply modules (two—One for operations and one for redundancy [1+1]) with the following
choices:
• 750-W port-side exhaust AC power supply with blue coloring (NXA-PAC-750W-PE)
• 750-W port-side intake AC power supply with burgundy coloring (NXA-PAC-750W-PI)
• 1100-W port-side exhaust AC power supply with blue coloring (NXA-PAC-1100W-PE)
• 1100-W port-side intake AC power supply with burgundy coloring (NXA-PAC-1100W-PI)
• 1100-W port-side exhaust DC power supply with blue coloring (NXA-PDC-1100W-PE2)
• 1100-W port-side intake DC power supply with burgundy coloring (NXA-PDC-1100W-PI2)
All fan modules and power supplies must use the same airflow direction.

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
power supplies have burgundy coloring. For port-side exhaust airflow, the fan and power supplies have blue
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 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.
All fan and power supply modules must have the same direction of airflow. Otherwise, the switch can overheat
and shut down.

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.
