CHAPTER 1
Overview
•Overview, on page 1
Overview
The Cisco Nexus 93108TC-FX switch (N9K-C93108TC-FX) is a 1-RU, fixed-port switch designed for
spine-leaf-APIC deployment in data centers. This switch has 48 10GBASE-T Application Policy Infrastructure
Controllers (APICs) facing ports that support 100-Megabits, 1- or 10-Gigabit Ethernet connections, and it has
six fixed 40/100-Gigabit QSFP28 spine-facing ports.
Autonegotiation is supported on 100M/1G/10G ports.
Note
The chassis for this switch includes the following user-replaceable components:
You can order this switch in a 24-port configuration (N9K-C93108TC-FX-24)

• 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 intake airflow (burgundy coloring) (NXA-PDC-930W-PI)
• 930-W DC power supply with port-side exhaust airflow (blue coloring) (NXA-PDC-930W-PE)
• 1200-W HVAC/HVDC power supply with dual-direction airflow (white coloring)
(N9K-PUV-1200W)
If you are using the 1200-W HVAC/HVDC power supply, the power
supply automatically uses the same airflow direction as the fan
modules installed switch.

There is a limit to USB 2.0 devices that use less than 2.5 W (less than 0.5 A inclusive of surge current). There
is no support for devices, such as external hard drives, that instantaneously draw more than 0.5 A.
Note
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 operating. If you have only one power
supply that is installed, you can install the replacement power supply in the open slot before removing the
original power supply.
Fans 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.
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.

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
High humidity can cause moisture to enter the switch. Moisture can cause corrosion of internal components
and degradation of properties such as electrical resistance, thermal conductivity, physical strength, and size.
The switch is rated to withstand from 5- to 95-percent (noncondensing) relative humidity.
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.
Cisco Nexus 93108TC-FX ACI Mode Hardware Installation Guide
5

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.
Cisco Nexus 93108TC-FX ACI Mode Hardware Installation Guide
6
Preparing the Site
Dust and Particulate Requirements

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.
Caution
Shock and Vibration Requirements
The switch has been shock- and vibration-tested for operating ranges, handling, and earthquake standards.
Grounding Requirements
The switch is sensitive to variations in voltage that is supplied by the power sources. Overvoltage, undervoltage,
and transients (or spikes) can erase data from memory or cause components to fail. To protect against these
types of problems, ensure that there is an earth-ground connection for the switch. You can connect the grounding
pad on the switch either directly to the earth-ground connection or to a fully bonded and grounded rack.
When you properly install the chassis in a grounded rack, the switch is grounded because it has a metal-to-metal
connection to the rack. Alternatively, you can ground the chassis by using a customer-supplied grounding
cable that meets your local and national installation requirements. For U.S. installations, we recommend
6-AWG wire. Connect your grounding cable to the chassis with a grounding lug (provided in the switch
accessory kit) and to the facility ground.
You automatically ground AC power supplies when you connect them to AC power sources. For DC power
supplies, you must connect a grounding wire when wiring the power supply to the DC power source.
Note
An electrical conducting path shall exist between the product chassis and the metal surface of the enclosure
or rack in which it is mounted or to a grounding conductor. Electrical continuity shall be provided by using
thread-forming type mounting screws that remove any paint or non-conductive coatings and establish a
metal-to-metal contact. Any paint or other non-conductive coatings shall be removed on the surfaces between
the mounting hardware and the enclosure or rack. The surfaces shall be cleaned and an antioxidant applied
before installation.
Note
Planning for Power Requirements
The switch includes two power supplies (1-to-1 redundancy with current sharing) in one of the following
combinations:
• Two 500-W AC power supplies
• Two 1200-W HVAC/HVDC power supplies
Cisco Nexus 93108TC-FX ACI Mode Hardware Installation Guide
7
Preparing the Site
Shock and Vibration Requirements

• Two 930-W DC power supplies
Both power supplies must be the same type. Do not mix AC, DC, and HVAC/HVDC power supplies in the
same chassis.
Note
For n+1 redundancy, you can use one or two power sources for the two power supplies. For n+nredundancy,
you must use two power sources and connect each power supply to a separate power source.
Note
Some of the power supply modules have rating capabilities that exceed the switch requirements. When
calculating your power requirements, use the switch requirements to determine the amount of power that is
required for the power supplies.
Note
To minimize the possibility of circuit failure, make sure that each power-source circuit that is used by the
switch is dedicated to the switch.
For AC input application, please refer to the following statement:
Note
Statement 1005—Circuit Breaker
This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that the
protective devices are rated not greater than 20A (North America), 16A (Europe), and 13A (UK).
Warning
For DC input application, please refer to the following statement:
Note
Statement 1005—Circuit Breaker
This product relies on the building's installation for short-circuit (overcurrent) protection.
• Ensure that the protective devices are rated not greater than 30A when the switch is powered with regular
DC power supplies (rated 48-60VDC).
• Ensure that the protective devices are rated not greater than 10A when the switch is powered with HVDC
power supplies (rated 240-350VDC).

Preparing the Site
Planning for Power Requirements

Statement 1033
Connect the unit only to DC power source that complies with the Safety Extra-Low Voltage (SELV)
requirements in IEC 60950 based safety standards.
Warning
We recommend 8-AWG wire for DC installations in the U.S.
Note
For the power cables to use with the power supplies, see Power Cable Specifications, on page 51.
Note
Airflow Requirements
The switch is positioned with its ports in either the front or the rear of the rack depending on your cabling
and maintenance requirements. You must have fan and power supply modules that move the coolant air from
the cold aisle to the hot aisle in one of the following ways:
• Port-side exhaust airflow—Cool air enters the chassis through the fan and power supply modules in the
cold aisle and exhausts through the port end of the chassis in the hot aisle.
• Port-side intake airflow—Cool air enters the chassis through the port end in the cold aisle and exhausts
through the fan and power supply modules in the hot aisle.
• Dual-direction airflow—The direction of the installed fan modules determines the airflow.
You can identify the airflow direction of each fan and power supply module by its coloring as follows:
• Blue coloring indicates port-side exhaust airflow.
• Burgundy coloring indicates port-side intake airflow.
• White coloring on HVAC/HVDC power supplies indicates dual-direction airflow.
To prevent the switch from overheating and shutting down, you must position the air intake for the switch in
a cold aisle. The fan and power supply modules must have the same direction of airflow (even if their coloring
is different). If you must change the airflow direction for the switch, you must shutdown the switch before
changing the modules.
Note
Rack and Cabinet Requirements
You can install the following types of racks or cabinets for your switch:
• Standard perforated cabinets
Cisco Nexus 93108TC-FX ACI Mode Hardware Installation Guide

Preparing the Site
Airflow Requirements

• Solid-walled cabinets with a roof fan tray (bottom-to-top cooling)
• Standard open four-post Telco racks
Work with your cabinet vendors to determine which of their cabinets meet the following requirements or see
the Cisco Technical Assistance Center (TAC) for recommendations:
• Use a standard 19-inch (48.3-cm), four-post Electronic Industries Alliance (EIA) cabinet or rack with
mounting rails that conform to English universal hole spacing per section 1 of the ANSI/EIA-310-D-1992
standard.
• The depth of a four-post rack must be 24 to 32 inches (61.0 to 81.3 cm) between the front and rear
mounting rails (for proper mounting of the bottom-support brackets or other mounting hardware).
• Required clearances between the chassis and the edges of its rack or the interior of its cabinet are as
follows:
• 4.5 inches (11.4 cm) between the front of the chassis and the interior of the cabinet (required for
cabling).
•3.0 inches (7.6 cm) between the rear of the chassis and the interior of the cabinet (required for airflow
in the cabinet if used).
• No clearance is required between the chassis and the sides of the rack or cabinet (no side airflow).
Also, you must have power receptacles that are located within reach of the power cords that are used with the
switch.
Statement 1048—Rack Stabilization
The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before installation
or servicing. Failure to stabilize the rack can cause bodily injury.
Warning
Clearance Requirements
Provide the chassis with adequate clearance between the chassis and any other rack, device, or structure so
that you can properly install the chassis. Provide the chassis with adequate clearance to route cables, provide
airflow, and maintain the switch. For the clearances required for an installation of this chassis in a four-post
rack, see the following figure.
