Ports for the Cisco Nexus 3016 Switch

The Cisco Nexus 3016 switch chassis includes the following ports:

• 40-Gigabit Ethernet uplink or downlink ports (16 ports)

• 100/1000 Ethernet management ports (2 ports)

• Console port (1 port)

• USB port (1 port)

The chassis has 16 40-Gigabit Ethernet ports that you can connect to hosts (uplink connections) or servers (downlink connections), which are often in the same rack or a nearby rack. Each of these ports uses a QSFP+ transceiver which is connected to one or four optical or copper cables. If one cable is used, it has a QSFP+ transceiver on the other end. If four cables are used, each of those cables has an SFP+ transceiver on the other end. The ports are numbered from left to right from 1 to 16 with the odd-numbered ports on top and the even-numbered ports on the bottom.

Two 100/1000 Ethernet management ports enable you to manage switch operations. You can connect to the switch through these two ports by using an RJ-45 connector on a copper cable.

One console port enables you to initially configure the switch and to perform troubleshooting operations. You use an RJ-45 connector with a copper cable to connect to this port.

One USB port enables you to save or load switch configurations.

Power Supply for the Cisco Nexus 3016 Switch

The Cisco Nexus 3000 Series switch has two slots for power supplies that are initially installed with one or two AC or DC power supplies that have forward or reverse airflow for their cooling. The switch requires only one power supply for its operations, but you can include a second one for redundancy.

To determine which part number to use when ordering replacement power supplies, see Tab le 1-2.

Ta b l e 1-2 Cisco Nexus 3016 Power Supply Part Numbers

Power Source Airflow Direction Power Supply Part Number

AC Forward N2200-PAC-400W=

AC Reverse N2200-PAC-400W-B=

DC Forward N2200-PDC-400W=

DC Reverse N3K-PDC-350W-B=

If the chassis has two power supplies, you can hot swap one of the power supplies during operations. If the chassis has only one power supply, you can install the new power supply in the open slot, turn on that power supply, and then remove the original power supply during operations.

Caution You can order replacement power supplies with forward airflow or reverse airflow. Be sure to order the

same direction of airflow as is used with the switch. If there is a black stripe across the front of the fan trays and power supplies, the switch is running reverse airflow and you must order power supplies with reverse airflow (each module has a black stripe). If there is no black stripe across the front of these modules, the switch is running forward airflow and you must order replacement modules with forward airflow (modules that do not have a black stripe).

Caution The switch must run with all of its power supply and fan tray modules taking in air from a cold aisle and

exhausting air to the hot aisle. If they take in air from a hot aisle, an overtemperature condition can occur and the switch will shut down. If the airflow directions are mixed in the same switch, you will see an error.

Note Never leave a power supply slot empty. If you remove a power supply, replace it with another one. If you

do not have a replacement power supply, leave the non functioning one in place until you can replace it or fill the slot with a filler blank module (part number N2200-P-BLNK).

For power supply specifications, see the “Power Specifications” section on page B-2. For information about the power supply LEDs and what they indicate, see the “Power Supply Status” section on

page D-3.

Fan Tray for the Cisco Nexus 3016 Switch

The Cisco Nexus 3016 switch ships with one fan tray, which is the same fan tray used by the Cisco Nexus 3064 switch (part number N3K-C3064-FAN for forward airflow or N3K-C3064-FAN-B for reverse airflow). You can hot swap the fan tray during operations but must replace it within two minutes or the switch can reach an overtemperature condition and shut down.

Caution You can order a replacement fan tray with forward airflow or reverse airflow. Be sure to order the same

direction of airflow as is used with the switch. If there is a black stripe across the front of the fan trays and power supplies, the switch is running reverse airflow and you must order a fan tray with reverse airflow. If there is no black stripe across the front of these modules, the switch has forward airflow and you must order replacement modules with forward airflow.

Caution The switch must run with all of its power supply and fan tray modules taking in air from a cold aisle and

Port Connections for the Cisco Nexus 3016 Switch

You use QSFP+ transceivers with the 16 networking ports used for uplinking and downlinking. For low-cost connections to switches in the same or adjacent racks, use QSFP+ transceivers with copper cables. For long distance connections, use the QSFP transceivers connected to optical cables.

Fan Tray for the Cisco Nexus 3048 Switch

The Cisco Nexus 3048 switch ships with one fan tray, which provides forward airflow from the fan tray to the port connector end exhaust (spares part number N3K-C3048-FAN=) or reverse airflow from the port connectors end of the chassis to the fan tray for exhaust (spares part number N3K-C3048-FAN-B). You can hot swap the fan tray during operations but must replace it within two minutes or the switch can reach an overtemperature condition and shut down.

Caution You can order a replacement fan tray with forward airflow or reverse airflow. Be sure to order the same

direction of airflow that is used with the switch. If there is a black stripe across the front of the fan trays and power supplies, the switch is running reverse airflow and you must order a fan tray with reverse airflow. If there is no black stripe across the front of these modules, the switch has forward airflow and you must order replacement modules with forward airflow.

Transceiver and Cabling Options for the Cisco Nexus 3132Q Switch

The Cisco Nexus 3132Q has 32 QSFP+ ports. QSFP+ technology allows a smooth transition from 10 to 40 Gigabit Ethernet infrastructures in data centers. Each of the Cisco Nexus 3132Q switch’s QSFP+ ports can operate in either native 40 Gigabit Ethernet mode or 4 x 10 Gigabit Ethernet mode. This switch supports both fiber and copper cabling solutions for these two modes.

For low-cost cabling, copper-based 40-Gbps Twinax cables can be used, and for longer cable reaches, short-reach optical transceivers are excellent. Connectivity can be established from the QSFP+ ports to 10 Gigabit Ethernet switches or hosts using a splitter cable that has a QSFP+ transceiver on one end and four SFP+ transceivers on the other end. Similar capability can be achieved on the fiber solution by using QSFP+ SR4 transceivers on both ends and procuring third-party fiber splitter MPO-to-LC cables.

Tabl e 1-14 lists the QSFP transceiver types supported.

Transceiver and Cabling Options for the Cisco Nexus 3172PQ Switch

The Cisco Nexus 3172PQ supports a wide variety of 1, 10, and 40 Gigabit Ethernet connectivity options. 1 and 10 Gigabit Ethernet connectivity is achieved in the first 48 ports, and 40 Gigabit Ethernet connectivity is achieved using QSFP+ transceivers in the last 6 ports. QSFP+ technology allows a smooth transition from 10 to 40 Gigabit Ethernet infrastructures in the data center. The Cisco Nexus 3172PQ supports connectivity over copper and fiber cables, providing excellent physical-layer flexibility. For low-cost cabling, copper-based 40-Gbps Twinax cables can be used, and for longer cable reaches, short-reach optical transceivers are optimal. Connectivity can be established from the QSFP ports to an upstream 10 Gigabit Ethernet switch using a splitter cable that has a QSFP transceiver on one end and four SFP+ transceivers on the other end. Similar capability can be achieved using optical transceivers by procuring third-party fiber splitters. supported.

Preparing for Installation

This section describes how to prepare the Cisco Nexus 3000 Series switch for installation. This section includes the following topics:

• Installation Options with Racks and Cabinets, page 2-2

• Airflow Direction, page 2-2

• Chassis Weight, page 2-3

• Installation Guidelines, page 2-3

• Required Equipment, page 2-4

• Unpacking and Inspecting the Switch, page 2-5

Installation Options with Racks and Cabinets

The Cisco Nexus 3000 Series switches can be installed in the following types of racks using a 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 Appendix A, “Cabinet and Rack

Specifications.”

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 tray and power supply modules. For instructions on how to use a rack-mount kit, see the

Airflow Direction

You can order the Cisco Nexus 3000 Series chassis with forward or reverse airflow. Forward airflow enters the chassis through the fan tray and power supply modules and exhausts through the port connections end of the chassis. Reverse airflow enters the chassis through the port connections end and exhausts through the fan tray and power supply modules. You must install a forward-airflow chassis with its fan tray and power supply modules located in a cold aisle, and you must install a reverse-airflow chassis with its port connections located in a cold aisle.

As shown in Figure 2-1, the modules in a chassis with forward airflow do not have a black stripe across the front of these modules and the modules with reverse airflow do have a black stripe across the front of these modules. All of the modules in a chassis must have the same direction of airflow, which means that all of the modules either have no stripe on them or all of the modules have a black stripe.

Figure 2-1 Distinguishing Between Chassis with Forward and Reverse Airflow

1 No black stripe indicates forward airflow. 2 Black stripe indicates reverse airflow.

Chassis Weight

When lifting the switch chassis, follow these guidelines:

• Disconnect all power and external cables before lifting the switch.

• Ensure that your footing is solid and the weight of the switch is evenly distributed between your feet.

• Lift the switch slowly, keeping your back straight. Lift with your legs, not with your back. Bend at

the knees, not at the waist.

Installation Guidelines

When installing the Cisco Nexus 3000 Series switch, follow these guidelines:

• Record the information listed in Appendix E, “Site Planning and Maintenance Records” as you

install and configure the switch.

• Ensure that there is adequate space around the switch to allow for servicing the switch and for

adequate airflow ( requirements).

• Ensure that the air-conditioning meets the heat dissipation requirements listed in Appendix B,

“Technical Specifications.”

• Ensure that the switch is going to be positioned so that it takes in air from a cold aisle and exhausts

air to the hot aisle. If there is a black stripe across the front of these modules, they have forward airflow and must be positioned with the fan tray and power supplies in a cold aisle. If there is a black stripe across the front of these modules, they have reverse airflow and must be positioned with the port connections in a cold aisle.

• Ensure that the cabinet or rack meets the requirements listed in Appendix A, “Cabinet and Rack

Specifications.”

Note Jumper power cords are available for use in a cabinet. See the “Jumper Power Cord” section on

page C-8.

• 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 and the power supply ground directly to an earth ground.

Appendix B, “Technical Specifications” lists the service and airflow

• Ensure that the site power meets the power requirements listed in Appendix B, “Technical

Specifications.” 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 systems such as the Cisco Nexus 3000 Series switches, which can have substantial current draw fluctuations because of fluctuating data traffic patterns.

• Ensure that circuits are sized according to local and national codes. For North America, the power

supply requires a 15-A or 20-A circuit.

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.

• Use the following screw torques when installing the switch:

–

Captive screws: 4 in-lb (0.45 N·m)

–

M3 screws: 4 in-lb (0.45 N·m)

–

M4 screws: 12 in-lb (1.36 N·m)

–

Required Equipment

Before beginning the installation, ensure that you have the following items available in addition to the switch and its accessory kit:

• Eight customer-supplied 12-24 or 10-32 screws (required for attaching slider rails and mounting

bracket to the mounting rails)

• Number 1 and number 2 Phillips screwdrivers with torque capability

• 3/16-inch flat-blade screwdriver

• Tape measure and level

• ESD wrist strap or other grounding device

• Antistatic surface

The following additional items (also not found in the accessory kit) are required to ground the chassis:

• Grounding cable (6 AWG recommended), sized according to local and national installation

requirements; the required length depends on the proximity of the switch to proper grounding facilities

• Crimping tool large enough to accommodate the girth of the grounding lug

10-32 screws: 20 in-lb (2.26 N·m) 12-24 screws: 30 in-lb (3.39 N·m)

Unpacking and Inspecting the Switch

Caution When handling switch components, wear a grounded ESD strap and handle modules by their handles and

carrier edges only. To ground the ESD strap, make sure that it is attached an earth ground or a grounded chassis (grounded through the power cable, the chassis ground, or the metal-to-metal contact with a grounded rack).

Tip Keep the shipping container in case the chassis requires shipping in the future.

Note The switch is thoroughly inspected before shipment. If any damage occurred during transportation or

any items are missing, contact your customer service representative immediately.

To inspect the shipment, follow these steps:

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:

• Grounding lug kit

• Rack-mount kit

• ESD wrist strap

• Cables with connectors

• Any optional items ordered

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 all of the power supplies and the fan tray have the expected direction of airflow.

Forward airflow modules do not have a black stripe, and reverse airflow modules do have a black stripe. The airflow direction must be the same for all modules.

Installing the Switch

This section describes how to use the rack-mount kit to install the Cisco Nexus 3000 Series switch into a cabinet or rack that meets the requirements described in

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

the rack. The rack-mount kit does not provide these screws.

To install the switch in a rack or cabinet, follow these steps:

Step 1 Install the front rack-mount brackets on the chassis as follows:

a. Determine whether the chassis port connections or the fan tray and power supply modules should

have easier access at the opening of the rack or cabinet. You will install that end of the chassis closest to the opening of the rack or cabinet.

b. On the side of the chassis by the end that is to have the easiest access, align four of the screw holes

in a front rack-mount bracket to four screw holes in the side of the chassis. If you want the fan tray and power supplies to have the easiest access, see callouts 1 and 2 in

Figure 2-1. If you want the port

connections to have the easiest access, see callouts 5 and 6 in Figure 2-2.

Note You can align any four of the holes in the front rack-mount bracket to four of the six screw holes

in the chassis. The holes that you use depend on the requirements of your rack and the amount of clearance required for port cables (3 inches [7.6 cm] minimum) and module handles (1 inch [2.5 cm] minimum).

Proper Grounding Practices

Grounding is one of the most important parts of equipment installation. Proper grounding practices ensure that the buildings and the installed equipment within them have low-impedance connections and low-voltage differentials between chassis. When you properly ground systems during installation, you reduce or prevent shock hazards, equipment damage due to transients, and data corruption. lists some general grounding practice guidelines.

Low Electromagnetic noise problems are not

anticipated, but installing a grounding system is always recommended. Best grounding recommendations should be followed as much as possible.

Note In all situations, grounding practices must comply with local National Electric Code (NEC)

requirements or local laws and regulations.

Note Always ensure that all of the modules are completely installed and that the captive installation screws

are fully tightened. In addition, ensure that all I/O cables and power cords are properly seated. These practices are normal installation practices and must be followed in all installations.

Establishing the System Ground

This section describes how to connect a system ground to the Cisco Nexus 3000 Series switch.

You must use the system ground on AC-powered systems if you are installing this equipment in a U.S. or European Central Office.

The system ground provides additional grounding for EMI shielding requirements and grounding for the low-voltage supplies (DC-DC converters) on the modules and is intended to satisfy the Telcordia Technologies requirements for supplemental bonding and grounding connections. You must observe the following system grounding guidelines for your chassis:

• You must install the system ground connection with any other rack or system power ground

connections that you make. The system ground connection is required if this equipment is installed in a U.S. or European Central Office.

• You must connect both the system ground connection and the power supply ground connection to

an earth ground. The system ground connection is required if this equipment is installed in a U.S. or European Central Office.

2-12

• You do not need to power down the chassis because the Cisco Nexus 3000 Series switches are

equipped with AC-input power supplies.

Required Tools and Equipment

To connect the system ground, you need the following tools and materials:

• Grounding lug—A two-hole standard barrel lug. This lug supports up to 6 AWG wire. This lug is

supplied in the accessory kit.

• Grounding screws—Two M4 x 8mm (metric) pan-head screws. These screws are supplied as part of

the accessory kit.

• Grounding wire—Not supplied in the accessory kit. The grounding wire should be sized according

to local and national installation requirements. Depending on the power supply and system, a 12 AWG to 6 AWG copper conductor is required for U.S. installations. Commercially available 6 AWG wire is recommended. The length of the grounding wire depends on the proximity of the switch to proper grounding facilities.

• No. 1 Phillips screwdriver.

• Crimping tool to crimp the grounding wire to the grounding lug.

• Wire-stripping tool to remove the insulation from the grounding wire.

Grounding the Cisco Nexus 3000 Series Chassis

The chassis has a grounding pad with two threaded M4 holes for attaching a grounding lug. The system ground is located on the left side of the chassis (left of the front) on the Cisco Nexus 3000 Series switches.

Electrostatic discharge (ESD) damage, which can occur when modules or other FRUs are improperly handled, results in intermittent or complete failures. Modules consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, always use an ESD grounding strap when handling modules.

For preventing ESD damage, follow these guidelines:

• Always use an ESD wrist strap and ensure that it makes maximum contact with bare skin.

• ESD grounding straps are available with banana plugs, metal spring clips, or alligator clips. All

chassis from the Cisco Nexus 3000 Series switches are equipped with a banana plug connector (identified by the ground symbol next to the connector) somewhere on the front panel. We recommend that you use a personal ESD grounding strap equipped with a banana plug.

• If you choose to use the disposable ESD wrist strap supplied with most FRUs or an ESD wrist strap

equipped with an alligator clip, you must attach the system ground lug to the chassis in order to provide a proper grounding point for the ESD wrist strap.

Note This system ground is also referred to as the network equipment building system (NEBS)

ground.

• If your chassis is not grounded by its connection to a grounded rack, you must connect the switch

to an Earth ground. See the instructions and the location of the chassis system ground pads.

“Establishing the System Ground” section on page 2-12 for installation

Note You do not need to attach a supplemental system ground wire to the system ground lug; the lug provides

a direct path to the bare metal of the chassis.

After you install the system ground lug, follow these steps to correctly attach the ESD wrist strap:

Step 1 Attach the ESD wrist strap to bare skin as follows:

a. If you are using the ESD wrist strap supplied with the field-replaceable units (FRUs), open the wrist

strap package and unwrap the ESD wrist strap. Place the black conductive loop over your wrist and tighten the strap so that it makes good contact with your bare skin.

b. If you are using an ESD wrist strap equipped with an alligator clip, open the package and remove

the ESD wrist strap. Locate the end of the wrist strap that attaches to your body and secure it to your bare skin.

Step 2 Grasp the spring or alligator clip on the ESD wrist strap and momentarily touch the clip to a bare metal

spot (unpainted surface) on a grounded rack. We recommend that you touch the clip to an unpainted rack rail so that any built-up static charge is then safely dissipated to the entire rack.

Step 3 Attach either the spring clip or the alligator clip to an earth ground (grounded rack or the screw holding

a grounding lug to the chassis):

a. If you are using the ESD wrist strap that is supplied with the FRUs, squeeze the spring clip jaws

open, position the spring clip to one side of the system ground lug screw head, and slide the spring clip over the lug screw head so that the spring clip jaws close behind the lug screw head.

OL-25338-04

Note The spring clip jaws do not open wide enough to fit directly over the head of the lug screw or

the lug barrel.

b. If you are using an ESD wrist strap that is equipped with an alligator clip, attach the alligator clip

directly over the head of the system ground lug screw or to the system ground lug barrel.

Connecting to the Network

This chapter describes how to connect the following ports on a Cisco Nexus 3000 Series switch:

• Console port —A direct local management connection used to initially configure the switch

• Management ports—An online management connection

• Uplink and downlink ports—Connections to hosts and servers

Caution When running power and data 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 in a grounded metallic conduit.

Preparing for Network Connections

When preparing your site for network connections to the Cisco Nexus 3000 Series switch, consider the following for each type of interface, and gather all the required equipment before connecting the ports:

• Cabling required for each interface type

• Distance limitations for each signal type

• Additional interface equipment required

Connecting to the Console Port

The console port is an RS-232 port with an RJ-45 interface. (See Figure 3-1.) The console port is an asynchronous (async) serial port; any device connected to this port must be capable of asynchronous transmission.

We recommend using this port to create a local management connection to set the IP address and other initial configuration settings before connecting the switch to the network for the first time.

Caution The console port can be used to connect to a modem. If you do not connect it to a modem, connect it

either before powering the switch on or after the switch has completed the boot process.

Figure 3-1 shows how to connect to the console port on the Cisco Nexus 3000 Series switch.

Figure 3-1 Connecting to the Console Port on a Cisco Nexus 3000 Series Switch

• Configure SNMP agent parameters.

• Download software updates.

Note To connect the console port to a computer terminal, the computer must support VT100 terminal

emulation. The terminal emulation software (such as HyperTerminal or Procomm Plus) makes communication between the Cisco Nexus 3000 Series switch and a computer possible during setup and configuration.

To connect the console port to a computer terminal, follow these steps:

Step 1 Configure the terminal emulator program to match the following default port characteristics: 9600 baud,

8 data bits, 1 stop bit, no parity.

Step 2 Connect the RJ-45 connector of the console cable to the console port (see Figure 3-1 on page 3-2) and

the DB-9 connector to the computer serial port.

Note For configuration instructions, see the appropriate Cisco Nexus 3000 Series CLI configuration

guide.

Connecting to the Management Port

Caution To prevent an IP address conflict, do not connect the management port to the network until the initial

configuration is complete (see the configuration instructions, see the Cisco Nexus 3000 Series CLI configuration guides.

This section describes how to connect the management ports to an external hub, switch, or router. The Ethernet connector port has an RJ-45 interface. To connect the management port to an external hub, switch, or router, follow these steps:

Step 1 Connect the appropriate modular cable to the Ethernet connector port:

• Use modular, RJ-45, straight-through UTP cables to connect the management port to an Ethernet

switch port or hub.

• Use a crossover cable to connect to a router interface.

Step 2 Connect the other end of the cable to the device.

Maintaining SFP and SFP+ Transceivers and Fiber-Optic Cables

Send document comments to nexus3k-docfeedback@cisco.com

Maintaining SFP and SFP+ Transceivers and Fiber-Optic Cables

QSFP+, SFP+, and SFP transceivers and fiber-optic cables must be kept clean and dust-free to maintain high signal accuracy and prevent damage to the connectors. Attenuation (loss of light) is increased by contamination and should be below 0.35 dB.

Consider the following maintenance guidelines:

• Optical transceivers are static sensitive. To prevent ESD damage, wear an ESD-preventive wrist

strap that is connected to the chassis.

• Do not remove and insert a transceiver more often than is necessary. Repeated removals and

insertions can shorten its useful life.

• Keep all optical connections covered when not in use. If they become dusty, clean before using to

prevent dust from scratching the fiber-optic cable ends.

• Do not touch ends of connectors to prevent fingerprints and other contamination.

• Clean regularly; the required frequency of cleaning depends upon the environment. In addition,

clean connectors if they are exposed to dust or accidentally touched. Both wet and dry cleaning techniques can be effective; refer to your site’s fiber-optic connection cleaning procedure.

• Inspect routinely for dust and damage. If damage is suspected, clean and then inspect fiber ends

under a microscope to determine if damage has occurred.

Replacing Components

This chapter describes how to replace the field replaceable units (FRUs) on the Cisco Nexus 3000 Series switch.

This chapter includes the following sections:

• Replacing a Power Supply, page 4-1

• Replacing a Fan Tray, page 4-4

Replacing a Power Supply

The Cisco Nexus 3000 Series switches support a front-end power supply that you can replace. The switch requires only one power supply for operations, so you can hot swap the redundant power supply during operations.

CHAPTER

Caution Be sure that the replacement power supply has the correct direction of airflow, which means that it takes

in air from the cold aisle and exhausts air to the hot aisle. It must also have the same direction of airflow as the other power supply (if installed) and fan tray. Otherwise, an overtemperature condition can occur.

This section includes the following topics:

• Removing an AC Power Supply, page 4-1

• Installing an AC Power Supply, page 4-2

• Removing a DC Power Supply, page 4-3

• Installing a DC Power Supply, page 4-4

Removing an AC Power Supply

Caution If you are using the Cisco Nexus 3000 Series switch with one power supply, removing the power supply

causes the switch to shut down. If the power supply is functioning, you can install a new power supply in the second power supply slot (see the switch to using that power supply.

Note Depending on the outlet receptacle on your power distribution unit, you may need the optional

jumper power cord to connect the Cisco Nexus 3000 Series switch to your outlet receptacle. See the “Jumper Power Cord” section on page C-8.

Step 5 Connect the other end of the power cable to an AC power source.

Caution In a system with dual power supplies, connect each power supply to a separate power source.

If a power source failure occurs, the second source will most likely still be available.

Step 6 Verify that the power supply is operational by checking that the power supply LED is green. For

information about what the power supply LEDs indicate, see the

Appendix D, “LED Descriptions.”

Removing a DC Power Supply

Caution If the switch has only one DC power supply, removing the power supply causes the device to shut down.

If you are using two power supplies and you remove one of them, the switch continues to operate.

To remove a DC power supply, follow these steps:

Step 1 Shut off the DC power to the power supply at the circuit breaker. Verify that both LEDs are off. Step 2 Unclip and remove the clear plastic cover that prevents access to the positive and negative terminals on

the DC power supply.

Step 3 Unfasten the positive power cable from the right terminal.

Note On early manufactured power supplies, the right terminal is labeled as -. On currently

manufactured power supplies, the right terminal is labeled as +.
