Overview
The Cisco Nexus 9336C-FX2-E switch (N9K-C9336C-FX2-E) is a 1-rack unit (RU), fixed-port switch designed
for deployment in data centers. 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.
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.
Note
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.

Preparing the Site

•Altitude Requirements, on page 5
•Dust and Particulate Requirements, on page 5
•Minimizing Electromagnetic and Radio Frequency Interference, on page 6
•Shock and Vibration Requirements, on page 7

•Rack and Cabinet Requirements, on page 7
Temperature Requirements
The switch requires an operating temperature of 32 to 104 degrees Fahrenheit (0 to 40 degrees Celsius). If
the switch is not operating, the temperature must be between –40 to 158 degrees Fahrenheit (–40 to 70 degrees
Celsius).
Humidity Requirements
Buildings in which the climate is controlled by air-conditioning in the warmer months and by heat during the
colder months usually maintain an acceptable level of humidity for the switch equipment. However, if the
switch is located in an unusually humid location, use a dehumidifier to maintain the humidity within an
acceptable range.
Altitude Requirements
Altitude rating is based on power supply installed; see critical components list in the system CB report for
altitude rating.
Dust and Particulate Requirements
Exhaust fans cool power supplies and system fans cool switches by drawing in air and exhausting air out
through various openings in the chassis. However, fans also ingest dust and other particles, causing contaminant

buildup in the switch and increased internal chassis temperature. Dust and particles can act as insulators and
interfere with the mechanical components in the switch. A clean operating environment can greatly reduce
the negative effects of dust and other particles.
In addition to keeping your environment free of dust and particles, follow these precautions to avoid
contamination of your switch:
• Do not permit smoking near the switch.
• Do not permit food or drink near the switch.
Minimizing Electromagnetic and Radio Frequency Interference
Electromagnetic interference (EMI) and radio frequency interference (RFI) from the switch can adversely
affect other devices, such as radio and television (TV) receivers. Radio frequencies that emanate from the
switch can also interfere with cordless and low-power telephones. Conversely, RFI from high-power telephones
can cause spurious characters to appear on the switch monitor.
RFI is defined as any EMI with a frequency above 10 kHz. This type of interference can travel from the switch
to other devices through the power cable and power source or through the air as transmitted radio waves. The
Federal Communications Commission (FCC) publishes specific regulations to limit the amount of EMI and
RFI that are emitted by computing equipment. Each switch meets these FCC regulations.
To reduce the possibility of EMI and RFI, follow these guidelines:
• Cover all open expansion slots with a blank filler plate.
• Always use shielded cables with metal connector shells for attaching peripherals to the switch.
When wires are run for any significant distance in an electromagnetic field, interference can occur to the
signals on the wires with the following implications:
• Bad wiring can result in radio interference emanating from the plant wiring.
• Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy the signal drivers
and receivers in the chassis and even create an electrical hazard by conducting power surges through
lines into equipment.
To predict and prevent strong EMI, you need to consult experts in radio frequency interference (RFI).
Note
The wiring is unlikely to emit radio interference if you use a twisted-pair cable with a good distribution of
grounding conductors. If you exceed the recommended distances, use a high-quality twisted-pair cable with
one ground conductor for each data signal when applicable.
If the wires exceed the recommended distances, or if wires pass between buildings, give special consideration
to the effect of a lightning strike in your vicinity. The electromagnetic pulse that is caused by lightning or
other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic
switches. You will want to consult experts in electrical surge suppression and shielding if you had similar
problems in the past.
