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.
Cisco Nexus 9508 ACI-Mode Switch Hardware Installation Guide
7

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 9508 ACI-Mode Switch Hardware Installation Guide
8
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
To plan for the power requirements of a switch, you must determine each of the following:
• Power requirements for all the switch components
• Minimum number of power supplies required to power the components that are installed in the switch.
Cisco Nexus 9508 ACI-Mode Switch Hardware Installation Guide
9
Preparing the Site
Shock and Vibration Requirements

• Power mode to use and the number of extra power supplies required for that mode.
Ensure that the circuit that is used for the switch is dedicated to the switch to minimize the possibility of circuit
failure.
Calculate the power that is required for operations (available power) and redundancy (reserve power), then
you can plan for the required number of input power receptacles. The power receptacles will be within reach
of the switch location.
Step 1 Determine the power requirement for the modules in the switch by summing the maximum wattage for each installed
module, see the following table.
