Overview

CHAPTER 1

Overview

• Overview, on page 1

The Cisco Nexus 9364C switch (N9K-C9364C) is a 2-rack unit (RU), fixed-port switch designed for spine-leaf-APIC deployment in data centers. This switch has the following ports:

• 64 40-/100-Gigabit QSFP28 interface ports (see the following figure to see how these 64 ports are numbered

• Ports 1 to 48 support 40/100-Gigabit speeds.

• Ports 49 to 64 support 40/100-Gigabit speeds.

• 2 1/10-Gigabit SFP+ interface ports

• 1 console port

• 2 management ports (one RJ-45 port and one SFP+ port)

• 2 USB ports

This switch includes the following user-replaceable components:

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

• Port-side exhaust fan module with blue coloring (NXA-FAN-160CFM-PE)

• Port-side intake fan module with burgundy coloring (NXA-FAN-160CFM-PI)

• Power supply modules (two—one for operations and one for redundancy [1+1]) with the following choices:

• 1200-W port-side exhaust AC power supply with blue coloring (NXA-PAC-1200W-PE)

• 1200-W port-side intake AC power supply with burgundy coloring (NXA-PAC-1200W-PI)

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

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

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

Cisco Nexus 9364C ACI-Mode Switch Hardware Installation Guide

Overview

Note

930-W DC power supply support 1+1 redundancy requires both of the following conditions:

• Ambient temperature of 104°F (40) or less and

• Use of 3.5 W QSFP+ transceivers or passive QSFP cables

With higher temperatures or other optics, the switch requires both power supplies for operations without power redundancy.

Note

Both power supplies should be the same type. Do not mix AC, DC, or HVAC/HVDC power supplies.

Overview

Note

All fan modules and power supplies must use the same airflow direction. If you are using the 1200-W HVAC/HVDC power supplies, those power supplies automatically use the same airflow direction as used by the fan modules.

Note

Caution

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 AC power supply modules have burgundy coloring. For port-side exhaust airflow, the fan and AC power supplies have blue coloring. You can also order the 1200-W HVAC/HVDC power supply which has dual-direction airflow with white coloring. Dual-direction airflow modules automatically use the airflow direction of the other modules installed in the switch.

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.

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.

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).

CHAPTER 2

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 85-percent (non-condensing) 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, you should use a dehumidifier to maintain the humidity within an acceptable range.

Altitude Requirements

The following table lists the maximum altitude that this switch is tested to operate. This switch is rated to operate at altitudes from 0 to 13,123 feet (0 to 4,000 meters). If you operate this switch at a higher altitude

Cisco Nexus 9364C ACI-Mode Switch Hardware Installation Guide

Dust and Particulate Requirements

(low pressure), the efficiency of forced and convection cooling is reduced and can result in electrical problems that are related to arcing and corona effects. This condition can also cause sealed components with internal pressure, such as electrolytic capacitors, to fail or to perform at a reduced efficiency.

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. A clean operating environment can greatly reduce the negative effects of dust and other particles, which act as insulators and interfere with the mechanical components in the switch.

In addition to regular cleaning, 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.

Preparing the Site

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, operating near the switch. 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 can be 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 between the field and 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.

Note

To predict and prevent strong EMI, you might need to consult experts in radio frequency interference (RFI).

The wiring is unlikely to emit radio interference if you use 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 9364C ACI-Mode Switch Hardware Installation Guide

Preparing the Site

Shock and Vibration Requirements

Caution

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 caused by lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic switches. You might want to consult experts in electrical surge suppression and shielding if you had similar problems in the past.

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 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 (we recommend 6-AWG wire for U.S. installations) connected to the chassis with a grounding lug (provided in the switch accessory kit) and to the facility ground.

Note

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.

Planning for Power Requirements

The switch includes two power supplies (1-to-1 redundancy with current sharing) in one of the following combinations:

• Two 1200-W AC power supplies

• Two 1200-W HVAC/HVDC power supplies

• Two 930-W DC power supplies

Note

For n+1 redundancy, you can use one or two power sources for the two power supplies. For n+n redundancy, you must use two power sources and connect each power supply to a separate power source.

Cisco Nexus 9364C ACI-Mode Switch Hardware Installation Guide

Planning for Power Requirements

The power supplies are rated to output up to either 1200 W (AC and HVAC/HVDC power supplies) or 930 W (DC power supplies) to the switch, but the switch requires less than those amounts of power from the power supply. To operate the switch you must provision enough power from the power source to cover the requirements of both the switch and a power supply. Typically, this switch and a power supply require about 429 W of power input from the power source, but you must provision as much as 1245 W power input from the power source to cover peak demand.

Note

Some of the power supply modules have Underwriter Labs (UL) rating capabilities that exceed the switch requirements. When calculating power requirements, use the switch requirements to determine the amount of power required for the power supplies.

To minimize the possibility of circuit failure, make sure that each power-source circuit used by the switch is dedicated to the switch.

Note

For AC input application, please refer to the statement below:

For the power cables to use with the power supplies, see Power Cable Specifications, on page 55.

Cisco Nexus 9364C ACI-Mode Switch Hardware Installation Guide

Preparing the Site

Airflow Requirements

The switch is designed to be positioned with its ports in either the front or the rear of the rack depending on your cabling and maintenance requirements. Depending on which side of the switch faces the cold aisle, 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—Coolant 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—Coolant 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—Airflow direction is determined by the airflow direction of the installed fan modules.

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.

Airflow Requirements

• Burgundy coloring indicates port-side intake airflow.

• White coloring on HVAC/HVDC power supplies indicates dual-direction airflow.

Note

To prevent the switch from overheating and shutting down, you must position the air intake for the switch in a cold aisle, and all of 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.

Rack and Cabinet Requirements

You can install the following types of racks or cabinets for your switch:

• Standard perforated cabinets

• Solid-walled cabinets with a roof fan tray (bottom-to-top cooling)

• Standard open four-post Telco racks

• Standard open two-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).

Cisco Nexus 9364C ACI-Mode Switch Hardware Installation Guide

Clearance Requirements

Preparing the Site

• 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).

Additionally, you must have power receptacles located within reach of the power cords used with the switch.

Warning

Statement 1048—Rack Stabilization

Stability hazard. The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before you slide the unit out for servicing. Failure to stabilize the rack can cause the rack to tip over.

Clearance Requirements

You must provide the chassis with adequate clearance between the chassis and any other rack, device, or structure so that you can properly install the chassis, 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.

Install a Rack

Before you install the switch, you must install a standard two- or four-post, 19-inch EIA data center rack (or a cabinet that contains such a rack) that meets the requirements listed in Overview of Racks, on page 49.

Step 1 Bolt the rack to the concrete subfloor before moving the chassis onto it.

Warning

Step 2 If the rack has bonded construction, connect it to the earth ground. This action enables you to easily ground the switch

and its components and to ground your electrostatic discharge (ESD) wrist strap to prevent damaging discharges when you handle ungrounded components before installing them.

Step 3 Include one or two power sources at the rack. For AC power, provide a power receptacle. For DC power, provide a circuit

breaker with terminals for connecting power cables.

Warning

Note

Statement 1048—Rack Stabilization

Statement 1018—Supply Circuit

Take care when connecting units to the supply circuit so that wiring is not overloaded.

If you are not using power redundancy or are using n+1 redundancy, you need only one power source. If you are using n+n redundancy, you need two power sources.
