Chapter 1. Overview

- Overview

Overview

The Cisco Nexus 9332PQ switch (N9K-C9332PQ) is a 1 rack unit (RU) switch that supports 32 40-Gigabit QSFP+ ports, one 100/1000 network management ports, one RS-232 console port for setting the initial switch configuration, and two USB ports for saving or loading switch configurations.

The chassis for this switch includes the following user-replaceable components:

- Fan modules (four) with the following airflow choices:

- Port-side intake fan module with burgundy coloring (NXA-FAN-30CFM-B)

- Port-side exhaust fan module with blue coloring (NXA-FAN-30CFM-F)

- Power supplies (two—one for operations and one for redundancy [1+1]) with the following choices:

- 650-W AC power supply with port-side intake airflow (burgundy coloring) (N9K-PAC-650W)

- 650-W AC power supply with port-side exhaust airflow (blue coloring) (N9K-PAC-650W-B)

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

- 930-W DC power supply with port-side intake airflow (green coloring) (UCSC-PSU-930WDC)

- 930-W DC power supply with port-side exhaust airflow (gray coloring) (UCS-PSU-6332-DC)

Note

Do not mix AC and DC power supplies in the same chassis.

Note

All fan modules and power supplies must use the same airflow direction during operations. If you are using the 1200-W HVAC/HVDC power supply, the power supply automatically uses the same airflow direction as used by the other modules in the switch.

This switch supports connections to the following Fabric Extenders (FEXs):

- Cisco Nexus 2348UPQ

- Cisco Nexus 2348TQ

- Cisco Nexus 2332TQ

- Cisco Nexus 2248PQ

- Cisco Nexus 2248TP-E

- Cisco Nexus 2248TP

- Cisco Nexus 2232TM-E

- Cisco Nexus 2232TM

- Cisco Nexus 2232PP

- Cisco Nexus 2224TP

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 (DC power supply modules have green coloring). For port-side exhaust airflow, the fan and AC power supplies have blue coloring (DC power supply modules have gray 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.

Note

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.

Caution

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.

Chapter 2. Preparing the Site

- Temperature Requirements

- Humidity Requirements

- Altitude Requirements

- Dust and Particulate Requirements

- Minimizing Electromagnetic and Radio Frequency Interference

- Shock and Vibration Requirements

- Grounding Requirements

- Planning for Power Requirements

- Airflow Requirements

- Rack and Cabinet Requirements

- Clearance Requirements

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 operate at 8- to 80-percent relative humidity, with a humidity gradation of 10 percent per hour. For nonoperating conditions, the switch can withstand from 5- to 95-percent 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

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 (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.

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.

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 650-W AC power supplies

- Two 1200-W HVAC/HVDC power supplies

- Two 930-W DC power supplies

Note

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+n redundancy, you must use two power sources and connect each power supply to a separate power source.

The power supplies are rated to output up to 650 W (AC power supplies), up to 1200 W (HVAC/HVDC power supplies), or up to 930 W (DC power supplies), 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 228 W of power input from the power source, but you must provision as much as 508 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 the power cables to use with the power supplies, see Power Cord Specifications.

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.

- Burgundy coloring indicates port-side intake airflow.

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

- Gray coloring on DC power supplies indicates port-side exhaust airflow.

- Green coloring on DC power supplies indicates port-side intake 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

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).

Additionally, you must have power receptacles located within reach of the power cords used with the switch. For the power cord specifications, see the Power Cord Specifications.

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.

Warning

Statement 1030—Equipment Installation

Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Installation Options with Racks and Cabinets

You can install the switch in the following types of racks using the rack-mount kit shipped with the switch:

- Open EIA rack

- Perforated EIA cabinet

The rack or cabinet that you use must meet the requirements listed in General Requirements for Cabinets and Racks.

The rack-mount kit enables you to install the switch into racks of varying depths. You can use the rack-mount kit parts to position the switch with easy access to either the port connections end of the chassis or the end of the chassis with the fan and power supply modules. For instructions on how to install the rack-mount kit, see the Installing the Switch.

Airflow Considerations

The switch comes with fan and power supply modules that have either port-side intake or port-side exhaust airflow for cooling the switch. If you are positioning the port end of the switch in a cold aisle, make sure that the switch has port-side intake fan modules with burgundy coloring. If you are positioning the fan and power supply modules in a cold aisle, make sure that the switch has port-side exhaust fan modules with blue colorings. All fan modules must have the same direction of airflow.

Installation Guidelines

When installing the switch, follow these guidelines:

- Record equipment and installation information in the forms presented in Appendix E, "Site Planning and Maintenance Records" as you install and configure the switch.

- Ensure that there is adequate clearance space around the switch to allow for servicing the switch and for adequate airflow.

- Ensure that you are positioning the switch in a rack so that it takes in cold air from the cold aisle and exhausts air to the hot aisle. If there is blue coloring on the fan modules, the switch is configured for port-side exhaust airflow and you must position the module side of the switch in a cold aisle. If there is burgundy coloring on the fan modules, the switch is configured for port-side intake airflow and you must position the port side of the switch in a cold aisle.

- Ensure that the chassis can be adequately grounded. If the switch is not mounted in a grounded rack, we recommend connecting both the system ground on the chassis directly to an earth ground.

- Ensure that the site power meets the power requirements listed in Switch Power Input Requirements. If available, you can use an uninterruptible power supply (UPS) to protect against power failures.

Caution

Avoid UPS types that use ferroresonant technology. These UPS types can become unstable with the switch, which can have substantial current draw fluctuations because of fluctuating data traffic patterns.

- Ensure that circuits are sized according to local and national codes. Typically, this often requires one or both of the following:

- AC power supplies typically require at least a 15-A or 20-A AC circuit, 100 to 240 VAC, and a frequency of 50 to 60 Hz.

- HVAC/HVDC power supplies require the following:

- HVAC input voltage range of 230 to 277 VAC with a frequency of 50 to 60 Hz

- HVDC input voltage range of -240 to -380 VDC

- DC power supplies require the following:

- DC input voltage range of –48 to -60 VDC nominal (self-ranging, –40 to –60 VDC)

- DC line input current (steady state) of 23 A peak at –48 VDC

Caution

To prevent loss of input power, ensure the total maximum loads on the circuits supplying power to the switch are within the current ratings for the wiring and breakers.

Unpacking and Inspecting the Switch

Before you install the switch, be sure to unpack and inspect the switch for damage or missing components. If anything is missing or damaged, contact your customer service representative immediately.

Tip

Keep the shipping container in case the chassis requires shipping at a later time.

Before You Begin

Before you unpack the switch and before you handle any switch components, be sure that you are wearing a grounded electrostatic discharge (ESD) strap. To ground the strap, attach it directly to an earth ground or to a grounded rack or grounded chassis (there must be a metal-to-metal connection to the earth ground).

Step 1

Compare the shipment to the equipment list provided by your customer service representative and verify that you have received all items, including the following:

- Additional kits (includes the Accessory Kit). See the Additional Kits appendix for detailed information.

Step 2

Check for damage and report any discrepancies or damage to your customer service representative. Have the following information ready:

- Invoice number of shipper (see packing slip)

- Model and serial number of the damaged unit

- Description of damage

- Effect of damage on the installation

Step 3

Check to be sure that each of the power supply and the fan tray modules have the expected direction of airflow as follows:

- Port-side intake airflow modules

- Red (fan modules and AC power supplies)

- Green (DC power supplies)

- Port-side exhaust airflow modules

- Blue (fan modules and AC power supplies)

- Gray (DC power supplies)

- Dual-direction airflow power-supply modules

- White (see the color of the fan modules to determine the airflow direction used)

Note:
All power supplies and fan modules must have the same direction of airflow.

Installing the Switch

To install the switch, you must attach front and rear mounting brackets to the switch, install slider rails on the rear of the rack, slide the switch onto the slider rails, and secure the switch to the front of the rack. Typically, the front of the rack is the side easiest to access for maintenance.

Note

You must supply the eight 10-32 or 12-24 screws required to mount the slider rails and switch to the rack.

Before You Begin

- You have inspected the switch shipment to ensure that you have everything ordered.

- Make sure that the switch rack-mount kit includes the following parts:

- Front rack-mount brackets (2)

- Rear rack-mount brackets (2)

- Slider rails (2)

- M4 x 0.7 x 8-mm Phillips countersink screws (12)

- The rack is installed and secured to its location.

Step 1

Install two front-mount brackets to the switch as follows:

1. Determine which end of the chassis is to be located in the cold aisle as follows:

- If the switch has port-side intake modules (fan modules with burgundy coloring), position the switch so that its ports will be in the cold aisle.

- If the switch has port-side exhaust modules (fan modules with blue coloring), position the switch so that its fan and power supply modules will be in the cold aisle.

Note:
If the power supply modules have white coloring, look at the fan modules to determine the airflow direction for the switch.

2. Position a front-mount bracket so that four of its screw holes are aligned to the screw holes on the side of the chassis.
Note:
You can align any four of the holes in the front rack-mount bracket to four of the six screw holes on the side of the chassis (see the two ways to mount these brackets in following figure). The holes that you use depend on the requirements of your rack and the amount of clearance required for interface cables (3 inches [7.6 mm] minimum) and module handles (1 inch [2.5 mm] minimum).

3. Secure the front-mount bracket to the chassis using four M4 screws and tighten each screw to 12 in-lb (1.36 N·m) of torque.

4. Repeat Step 1 for the other front rack-mount bracket on the other side of the switch and be sure to position that bracket the same distance from the front of the switch.

Step 2

Install the two rear rack-mount brackets on the chassis as follows:

1. Align the two screw holes on a rear rack-mount bracket to the middle two screw holes in the remaining six screw holes on a side of the chassis. If you are aligning the guide to holes that are near the port connections end of the chassis, see Callout 3 in the previous figure. Otherwise, see Callout 7 in the previous figure.

2. Attach the guide to the chassis using two M4 screws (see Callout 4 or 8 in the previous figure). Tighten the screws to 12 in-lb (1.36 N·m) of torque.

3. Repeat Step 2 for the other rear rack-mount bracket on the other side of the switch.

Step 3

If you are not installing the chassis into a grounded rack, you must attach a customer-supplied grounding wire to the chassis as explained in Grounding the Chassis. If you are installing the chassis into a grounded rack, you can skip this step.

Step 4

Install the slider rails on the rack or cabinet as follows:

1. Determine which two posts of the rack or cabinet you should use for the slider rails. Of the four vertical posts in the rack or cabinet, two will be used for the front mount brackets attached to the easiest accessed end of the chassis, and the other two posts will have the slider rails.

2. Position a slider rail at the desired level on the back side of the rack and use two 12-24 screws or two 10-32 screws, depending on the rack thread type, to attach the rails to the rack (see the following figure). Tighten 12-24 screws to 30 in-lb (3.39 N·m) of torque and tighten 10-32 screws to 20 in-lb (2.26 N·m) of torque.

1

3. Repeat Step 3 to attach the other slider rail to the other side of the rack.
To make sure that the slider rails are at the same level, you should use a level tool, tape measure, or carefully count the screw holes in the vertical mounting rails.

Step 5

Insert the switch into the rack and attach it as follows:

1. Holding the switch with both hands, position the two rear rack-mount brackets on the switch between the rack or cabinet posts that do not have slider rails attached to them (see the following figure).

1

Align the two rear rack-mount bracket guides with the slider rails installed in the rack.

3

Front-mount brackets.

2

Slide the rack-mount guides onto the slider rails until the front rack-mount brackets come in contact with the front rack-mount rails.

4

2. Align the two rear rack-mount guides on either side of the switch with the slider rails installed in the rack. Slide the rack-mount guides onto the slider rails, and then gently slide the switch all the way into the rack until the front rack-mount brackets come in contact with two rack or cabinet posts.
Note:
If you attached a grounding cable to the chassis, you will need to bend one of the rack-mount rails slightly to allow the grounding lug to go behind the rail.

3. Holding the chassis level, insert two screws (12-24 or 10-32, depending on the rack type) in each of the two front rack-mount brackets (using a total of four screws) and into the cage nuts or threaded holes in the vertical rack-mounting rails (see the following figure).

4. Tighten the 10-32 screws to 20 in-lb (2.26 N·m) or tighten the 12-24 screws to 30 in-lb (3.39 N·m).

Step 6

If you attached a grounding wire to the chassis grounding pad, connect the other end of the wire to the facility ground.

Grounding the Chassis

The switch chassis is automatically grounded when you properly install the switch in a grounded rack with metal-to-metal connections between the switch and rack.

You can alternatively ground the chassis (this is required if the rack is not grounded) by attaching a customer-supplied grounding cable to the chassis grounding pad and the facility ground.

Warning

Statement 1024—Ground Conductor

This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.

Warning

Statement 1046—Installing or Replacing the Unit

When installing or replacing the unit, the ground connection must always be made first and disconnected last.

Before You Begin

Before you can ground the chassis, you must have a connection to the earth ground for the data center building.

Step 1

Use a wire-stripping tool to remove approximately 0.75 inch (19 mm) of the covering from the end of the grounding wire.

Step 2

Insert the stripped end of the grounding wire into the open end of the grounding lug, and use a crimping tool to crimp the lug to the wire (see Callout 2 in the following figure). Verify that the ground wire is securely attached to the grounding lug by attempting to pull the wire out of the crimped lug.

3

2 M4 screws used to secure the grounding lug to the chassis

2

Grounding cable, with 0.75 in. (19 mm) of insulation stripped from one end, inserted into the grounding lug and crimped in place

Step 3

Secure the grounding lug to the chassis grounding pad with two M4 screws (see Callouts 1 and 3 in the previous figure), and tighten the screws to 11 to 15 in-lb (1.24 to 1.69 N·m) of torque.

Step 4

After you install the chassis, prepare the other end of the grounding wire and connect it to an appropriate grounding point in your site to ensure an adequate earth ground for the switch.

Starting the Switch

You start the switch by connecting it to its dedicated power source. If you need n+1 redundancy, you must connect each of the power supplies to one or two power sources. If you need n+n redundancy, you must connect each power supply in a switch to a different power source.

Before You Begin

- The switch must be installed and secured to a rack or cabinet.

- The switch must be adequately grounded.

- The rack must be close enough to the dedicated power source so that you can connect the switch to the power source by using a designated power cables.

- You have the designated power cables for the power supplies that you are connecting to the dedicated power sources.

Note

Depending on the outlet receptacle on your AC power distribution unit, you might need an optional jumper power cord to connect the switch to your outlet receptacle.

- The switch is not connected to the network (this includes any management or interface connections).

- The fan and power supply modules are fully secured in their chassis slots.

All of the fan slots must be filled with fan modules and the power supply slots must be filled with the same types of power supplies (do not mix AC and DC power supplies).

Step 1

For each AC power supply, do the following:

1. Using the recommended AC power cable for your country or region, connect one end to the AC power supply.

2. Connect the other end of the power cable to the AC power source.

Step 2

For each HVAC/HVDC power supply, connect it to a power source as follows:

1. Using the recommended high voltage power cable for your country or region, connect the Anderson Power Saf-D-Grid connector on the power cable to the power receptacle on the power supply. Make sure that the connector clicks when fully pushed into the receptacle.

2. Connect the other end of the power cable to a power source.

- When connecting to an HVAC power source, insert the C14 or LS-25 plug in a receptacle for the HVAC power source.

- When connecting to an HVDC power source, do the following:

1. Verify that the power is turned off at a circuit breaker for the power source terminals.

2. Remove the nuts from each of the terminal posts for the power supply.

3. Place the power cable negative-wire terminal ring on the negative terminal for the power source and secure them with a terminal nut.

4. Place the power cable positive-wire terminal ring on the positive terminal for the power source and secure them with a terminal nut.

5. Place the power cable ground-wire terminal ring on the ground terminal for the power source and secure them with a terminal nut.

6. If there is a safety cover for the power source terminals, place and secure it over the terminals to avoid an electrical shock hazard.

7. Turn on the power at the power source circuit breaker.

Step 3

For each DC power supply, do the following:

1. Turn off the circuit breaker for the power source to avoid an electrical shock hazard.

2. Verify that the power cable wires from the power source are connected to a connector block.
If the positive, negative, and grounding wires from the power source are not connected to the connector block, see Wiring a 48 V DC Electrical Connector Block.

3. Insert the connector block into the receptacle on the power supply. Make sure that the connector block clicks when fully inserted in the receptacle and does not pull out.

4. If there is a safety cover for the terminals, place and secure it over the terminals to avoid an electrical shock hazard.

5. Turn on the power at the circuit breaker for the DC power source.

Step 4

Verify that the power supply LED is on and green.

Step 5

Listen for the fans; they should begin operating when the power supply is powered.

Step 6

After the switch boots, verify that the following LEDs are lit:

- On the fan modules, the Status (STA or STS) LED is green.

If a fan module Status LED is not green, try reinstalling the fan module.

- After initialization, the switch chassis Status (labeled as STA or STS) LED is green.

Step 7

Verify that the system software has booted and the switch has initialized without error messages.

Step 8

Complete the worksheets provided in Appendix E, "Site Planning and Maintenance Records," for future reference.
Note:

A setup utility automatically launches the first time that you access the switch and guides you through the basic configuration. For instructions on how to configure the switch and check module connectivity, see the appropriate Cisco Nexus 9000 Series configuration guide.

Chapter 4. Connecting the Switch to the Network

- Overview of Network Connections

- Connecting a Console to the Switch

- Creating the Initial Switch Configuration

- Setting Up the Management Interface

- Connecting Interface Ports to Other Devices

Overview of Network Connections

After you install the switch in a rack and power it up, you are ready to make the following network connections:

- Console connection—This is a direct local management connection that you use to initially configure the switch. You must make this connection first to initially configure the switch and determine its IP address, which is needed for the other connections.

- Management connection—After you complete the initial configuration using a console, you can make this connection to manage all future switch configurations.

- Uplink and downlink interface connections—These are connections to hosts and servers in the network.

Each of these connection types is explained in one of the sections that follow.

Note

When running cables in overhead or subfloor cable trays, we strongly recommend that you locate power cables and other potential noise sources as far away as practical from network cabling that terminates on Cisco equipment. In situations where long parallel cable runs cannot be separated by at least 3.3 feet (1 meter), we recommend that you shield any potential noise sources by housing them in a grounded metallic conduit.

Connecting a Console to the Switch

Before you create a network management connection for the switch or connect the switch to the network, you must create a local management connection through a console terminal and configure an IP address for the switch. You also can use the console to perform the following functions, each of which can be performed through the management interface after you make that connection:

- Configure the switch using the command-line interface (CLI).

- Monitor network statistics and errors.

- Configure Simple Network Management Protocol (SNMP) agent parameters.

- Download software updates.

You make this local management connection between the asynchronous serial port on a supervisor module and a console device capable of asynchronous transmission. Typically, you can use a computer terminal as the console device. On the supervisor modules, you use the console serial port.

Note

Before you can connect the console port to a computer terminal, make sure that the computer terminal supports VT100 terminal emulation. The terminal emulation software makes communication between the switch and computer possible during setup and configuration.

Before You Begin

- The switch must be fully installed in its rack, connected to a power source, and grounded.

- The necessary cabling for the console, management, and network connections must be available.

- An RJ-45 rollover cable is provided in the switch accessory kit.

- Network cabling should already be routed to the location of the installed switch.

Step 1

Configure the console device to match the following default port characteristics:

- 9600 baud

- 8 data bits

- 1 stop bit

- No parity

Step 2

Connect an RJ-45 rollover cable to the console port on the switch.
You can find this cable in the accessory kit.

Step 3

Route the RJ-45 rollover cable to the console or modem.

Step 4

Connect the other end of the RJ-45 rollover cable to the console or to a modem.

What to Do Next

You are ready to create the initial switch configuration (see Creating the Initial Switch Configuration).

Creating the Initial Switch Configuration

You must assign an IP address to the switch management interface so that you can then connect the switch to the network.

When you initially power up the switch, it boots up and asks you a series of questions to configure the switch. To enable you to connect the switch to the network, you can use the default choices for each configuration except the IP address, which you must provide. You can perform the other configurations at a later time as described in the Cisco Nexus 9000 Series NX-OS Fundamentals Configuration Guide.

Note

You should also know the unique name needed to identify the switch among the devices in the network.

Before You Begin

- A console device must be connected with the switch.

- The switch must be connected to a power source.

- Determine the IP address and netmask needed for the following interfaces:

- Management (Mgmt0) interface

Step 1

Power up the switch by connecting each installed power supply to an AC circuit.
If you are using the combined or power-supply (n+1) power mode, connect all of the power supplies to the same AC circuit. If you are using the input-source (n+n) power mode, connect half of the power supplies to one AC circuit and the other half to another AC circuit.

The Input and Output LEDs on each power supply light up (green) when the power supply units are sending power to the switch, and the software asks you to specify a password to use with the switch.

Step 2

Enter a new password to use for this switch.
The software checks the security strength of your password and rejects your password if it is not considered to be a strong password. To increase the security strength of your password, make sure that it adheres to the following guidelines:

- At least eight characters

- Minimizes or avoids the use of consecutive characters (such as "abcd")

- Minimizes or avoids repeating characters (such as "aaabbb")

- Does not contain recognizable words from the dictionary

- Does not contain proper names

- Contains both uppercase and lowercase characters

- Contains numbers as well as letters

Examples of strong passwords include the following:

- If2CoM18

- 2004AsdfLkj30

- Cb1955S21

Note:
Clear text passwords cannot include the dollar sign ($) special character.

Tip:
If a password is trivial (such as a short, easy-to-decipher password), the software will reject your password configuration. Be sure to configure a strong password as explained in this step. Passwords are case sensitive.

If you enter a strong password, the software asks you to confirm the password.

Step 3

Enter the same password again.
If you enter the same password, the software accepts the password and begins asking a series of configuration questions.

Step 4

Until you are asked for an IP address, you can enter the default configuration for each question.
Repeat this step for each question until you are asked for the Mgmt0 IPv4 address.

Step 5

Enter the IP address for the management interface.
The software asks for the Mgmt0 IPv4 netmask.

Step 6

Enter a network mask for the management interface.
The software asks if you need to edit the configuration.

Step 7

Enter no to not edit the configuration.
The software asks if you need to save the configuration.

Step 8

Enter yes to save the configuration.

What to Do Next

You can now set up the management interface for each supervisor module on the switch.

Setting Up the Management Interface

The management port (MGMT ETH) provides out-of-band management, which enables you to use the command-line interface (CLI) to manage the switch by its IP address. This port uses a 10/100/1000 Ethernet connection with an RJ-45 interface.

Before You Begin

- The switch must be powered on.

- The switch must be initially configured using a console.

Step 1

Connect the RJ-45, UTP cable to the MGMT ETH port on the switch.

Step 2

Connect the other end of the cable to a 10/100/1000 Ethernet port on a network device.

What to Do Next

You are ready to connect the interface ports on each of the line cards to the network.

Connecting Interface Ports to Other Devices

After you perform the initial configuration for the switch and create a management connection, you are ready to connect the interface ports on the switch to other devices. Depending on the types of interface ports on the switch, you will need to use interface cables with QSFP+, SFP+, or SFP transceivers to connect the switch to other devices.

If the transceivers that you are using can be separated from their optical cables, install the transceivers without their cables before inserting the cables into the transceivers. This helps to prolong the life of both the transceiver and cables. When removing transceivers from the switch, it is best to remove the optical cable first and then remove the transceiver.

Chapter 5. Replacing Components

- Replacing a Fan Module

- Replacing a Power Supply Module

Replacing a Fan Module

You can replace one of the four fan modules at a time while the switch is operating so long as you perform the replacement within one minute. If you cannot perform the replacement within one minute, leave the original fan module in the chassis to maintain the designed airflow until you have the replacement fan module on hand and can perform the replacement.

Caution

If you are replacing a module during operations, be sure that the replacement fan module has the correct direction of airflow, which means that it has the same airflow direction as the other modules in the chassis. Also, be sure that the airflow direction takes in air from a cold aisle and exhausts to a hot aisle. Otherwise, the switch can overheat and shutdown.

If you are changing the airflow direction of all the modules in the chassis, you must shutdown the switch before replacing all the fan and power supply modules with modules using the other airflow direction. During operations, all of the modules must have the same direction of airflow.

- Installing a Fan Module

Removing a Fan Module

Warning

Statement 263—Fan Warning

The fans might still be turning when you remove the fan assembly from the chassis. Keep fingers, screwdrivers, and other objects away from the openings in the fan assembly's housing.

Step 1

On the fan module that you are removing, press the two sides of the fan module handle next to where it connects to the fan module and pull on the handles enough to unseat it from its connectors.

Step 2

Holding the handle, pull the module out of the chassis.
Caution:
Do not touch the electrical connectors on the back side of the module and prevent anything else from coming into contact with and damaging the connectors.

Installing a Fan Module

Before You Begin

- A fan slot must be open and ready for the new fan module to be installed.

- You must have a new fan module on hand and ready to install within one minute of removing the original fan module if the switch is operating.

- The new fan module must have the same airflow direction as the other fan and power supply modules installed in the switch. All of these modules must have either burgundy coloring (port-side intake airflow) or they must all have blue coloring (port-side exhaust airflow).

Step 1

Holding the fan module by its handle, align the back of the fan module (the side with the electrical connectors) to the open fan slot in the chassis.

Step 2

Slide the fan module into the slot until it clicks in place.

Step 3

Verify that the Status (STS) LED turns on and becomes green.

Replacing a Power Supply Module

The switch requires two power supplies for redundancy. With one power supply providing the necessary power for operations, you can replace the other power supply during operations so long as the new power supply has the same airflow direction as the other modules in the chassis.

Note

If you need to change the airflow direction of the switch modules, you must shut down the switch before changing all of the modules to modules using the other airflow direction.

You can replace a power supply with any other power supply that is supported by the same switch so long as it provides the same direction of airflow as the fan modules installed in the switch and uses the same type of power source as the other power supply installed in the switch (do not mix AC, DC, and HVAC/HVDC power supplies in the same switch). The coloring of the latch handle on the power supply indicates the airflow direction as explained in the following table that lists the supported power supplies for this switch.

What to Do Next

You are ready to install a DC power supply in the open slot.

Installing an AC Power Supply

You can replace one power supply while the other one provides power to the switch.

Before You Begin

- The power supply that you are installing must be capable of using the same airflow direction as the fan trays installed in the same switch and it must use the same type of power source as the other power supply installed in the same switch (do not mix AC and DC power supplies in the same switch).

Note

DC power supplies with green coloring have the same port-side intake airflow direction as the power supplies with red coloring, and DC power supplies with gray coloring have the same port-side exhaust airflow direction as the power supplies with blue coloring. HVAC/HVDC power supplies automatically use the same airflow direction as the installed fan modules. If the power supply that you are replacing has a different color handle than the replacement power supply, verify that it has or will have the same airflow direction as the other modules in the switch.

- An AC power source must be within reach of the power cable that will be used with the replacement power supply. If you are using n+n power redundancy, there must be a separate power source for each power supply installed in the chassis. Otherwise, only one power source is required.

- There must be an earth ground connection to the chassis that you are installing the replacement module. Typically, the chassis is grounded by its metal-to-metal connection with a grounded rack. If you need to ground the chassis, see Grounding the Chassis.

Step 1

Holding the replacement power supply with one hand underneath the module and the other hand holding the handle, turn the power supply so that its release latch is on the right side and align the back end of the power supply (the end with the electrical connections) to the open power supply slot before carefully sliding the power supply all the way into the slot until it clicks into place.

Appendix A. Rack Specifications

- Overview of Racks

- General Requirements for Cabinets and Racks

- Requirements Specific to Standard Open Racks

- Requirements Specific to Perforated Cabinets

- Cable Management Guidelines

Overview of Racks

You can install the switch in the following types of cabinets and racks, assuming an external ambient air temperature range of 0 to 104°F (0 to 40°C):

- Standard perforated cabinets

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

- Standard open racks

Note

If you are selecting an enclosed cabinet, we recommend one of the thermally validated types, either standard perforated or solid-walled with a fan tray.

Note

We do not recommend that you use racks that have obstructions (such as power strips), because the obstructions could impair access to field-replaceable units (FRUs).

General Requirements for Cabinets and Racks

The cabinet or rack must also meet the following requirements:

- Standard 19-inch (48.3 cm) (four-post EIA cabinet or rack, with mounting rails that conform to English universal hole spacing per section 1 of ANSI/EIA-310-D-1992). For more information, see Requirements Specific to Perforated Cabinets.

- The minimum vertical rack space requirement per chassis is one RU (rack unit), equal to 1.75 inches (4.4 cm).

- The width between the rack-mounting rails must be at least 17.75 inches (45.0 cm) if the rear of the device is not attached to the rack. For four-post EIA racks, this measurement is the distance between the two front rails.

Four-post EIA cabinets (perforated or solid-walled) must meet the following requirements:

- The minimum spacing for the bend radius for fiber-optic cables should have the front-mounting rails of the cabinet offset from the front door by a minimum of 3 inches (7.6 cm).

- The distance between the outside face of the front mounting rail and the outside face of the back mounting rail should be 23.0 to 30.0 inches (58.4 to 76.2 cm) to allow for rear-bracket installation.

Requirements Specific to Standard Open Racks

If you are mounting the chassis in an open rack (no side panels or doors), ensure that the rack meets the following requirements:

- The minimum vertical rack space per chassis must be one rack unit (RU), equal to 1.75 inches (4.4 cm).

- The distance between the chassis air vents and any walls should be 2.5 inches (6.4 cm).

Requirements Specific to Perforated Cabinets

A perforated cabinet has perforations in its front and rear doors and side walls. Perforated cabinets must meet the following requirements:

- The front and rear doors must have at least a 60 percent open area perforation pattern, with at least 15 square inches (96.8 square cm) of open area per rack unit of door height.

- The roof should be perforated with at least a 20 percent open area.

- The cabinet floor should be open or perforated to enhance cooling.

The Cisco R Series rack conforms to these requirements.

Cable Management Guidelines

To help with cable management, you might want to allow additional space in the rack above and below the chassis to make it easier to route all of the fiber optic or copper cables through the rack.
