CHAPTER

Overview

The Cisco Nexus Fabric Extenders (FEXs) supp ort 100M/1G/10G Ethernet en vironments while allo wing transparent migration to 10-Gigabit Ethernet virtual machine aware unified fabric technologies. The Cisco Nexus FEXs behave as remote I/O modules for a parent Cisco Nexus switch. The FEX is an extension of the parent Cisco Nexus switch fabric, with the FEX and the parent Cisco Nexus switch together forming a virtual modular system.

A Cisco Nexus FEX forwards all the traffic to the parent Cisco Nexus Switch over 10/40-Gigabit Ethernet uplinks. Passing all traffic to the parent switch allows traffic forwarding to be controlled according to policies established on the parent Cisco Nexus switch with a single point of management.

This chapter describes the Cisco Nexus Fabric Extenders (FEXs) and includes these sections:

an extension of the parent Cisco Nexus 9332PQ, 9372PX, 9372PX-E, 9396PX, or 9500 switch fabric, with the FEX and the switch becoming a virtual modular system. The FEX forwards all 100/1000 Ethernet or 1/10-Gigabit Ethernet traffic from the hosts to the switch over 10- or 40-Gigabit uplinks.

Power Supply and Fan Modules

Each FEX chassis supports one or two power modules (one for operations and one for redundancy) and 1, 3, or 4 fan modules (depending on the FEX model). If the chassis has only one power supply, make sure that there is a blank module (N2200-P-BLNK) installed in the unused po wer supply slot to preserve the designed airflow.

Each FEX chassis supports power supply and fan modules that have either port-side intake or port-side exhaust airflow.

Caution All of the power supply and fan modules in the same chassis must have the same airflow direction and

the cold air intake for the chassis must be located in a cold aisle or else the switch can overheat and shut down.

Port-side intake modules have red coloring and port-side exhaust modules have blue coloring. Power supply coloring is displayed on the module release lat ches, and fan module coloring is d isplayed as either a stripe on the front of the module or as the color of the module handle.

Note Some older power supply and f an modules use black stripes for port-side intake airflo w and no st ripe for

port-side exhaust airflow.

You can hot swap a power supply module as long as there is another power supply module functioning in the chassis. You can hot swap a fan module in a chassis with multiple fa n modules as long as t he other fan modules are installed and functioning. You can hot swap a fan module in a chassis with a single fan module as long as you replace it within 60 seconds.

For the power supplies supported by each FEX chassis, see Table 1-5. For the fan modules supported by each FEX chassis, see Table 1-6.

Installation Options

The Cisco Nexus FEX can be installed using the following methods:

• In an open EIA rack, using the following items:

–

The rack-mount kit shipped with the device

Chapter 2 Installing a Cisco Nexus Fabric Extender

–

The EIA Shelf Bracket Kit (an optional kit, purchased separately)

• In a perforated or solid-walled EIA cabinet, using one of the following:

–

The rack-mount kit shipped with the device

–

The EIA Shelf Bracket Kit (an optional kit, purchased separately)

For instructions on installing the device using the rack-mount kit shipped with the device, see the

“Installing the Cisco Nexus Fabric Extender Chassis in a Cabinet or Rack” section on page 2-6.

Note The optional EIA Shelf Bracket Kit is not provided with the device. To order the kit, contact your device

provider.

Airflow Considerations

Airflow through the Cisco Nexus FEX is from the port side exhaust to the back or the back to the port side exhaust. To ensure proper airflow, follow these guidelines:

• Position the chassis so that its air intake side (port side exha ust side for por t side exhaust airflow or

back side for port side intake airflow) is in a cold aisle. Otherwise, an o vertemperature condition can occur and the system can shut down.

• Avoid having the air intake where other systems exhaust air.

• Due to the shallow depth of the Cisco Nexus FEX, it is also possi ble for air to recirculate across the

top and bottom of the chassis in a partially populated rack.

2-2

• Make sure that the fan tray and power supply modules all use the same direction of airflow. All of

the modules should have no black stripe (port side e xhaust airflo w) or all of the modules should ha ve a black stripe (port side intake airflow).

Cisco Nexus 2000 Series Hardware Installation Guide

Chapter 2 Installing a Cisco Nexus Fabric Extender

Note If the switch is powered up with modules that hav e different airflow directions, you need to shut

down the switch before replacing the modules with the wrong airflow direction.

• Maintain ambient airflow throughout the data center to ensure normal operation.

• Consider the heat dissipation of all equipment when determining air-conditioning requirements.

When evaluating airflow requirements, take into consideration that hot air generated by equipment at the bottom of the rack can be drawn in the intake ports of the equipment above.

• If you mount a chimney type of rack, avoid mounting it in a way that is contrary to the direction of

flow in the chimney, where the chimney overpowers the system fans.

Chassis Weight

When lifting the system, follow these guidelines:

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

• Have two people lift the system. The Cisco Nexus FEXs can weigh up to 18.5 pounds (8.4 kg).

• Ensure that your footing is solid and the weight of the system is evenly distributed between your

feet.

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

the knees, not at the waist.

Preparing for Installation

Installation Guidelines

When installing the Cisco Nexus FEX, follow these guidelines:

• Plan your site configuration and prepare the site before installing the chassis. Appendix G, “Site

Preparation and Maintenance Records,” lists the recommended site planning tasks.

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

install and configure the device.

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

adequate airflow (Appendix B, “Technical Specifications,” lists airflow requirements).

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

“Technical Specifications,”

• Ensure that the chassis air intake wil l be lo cate d i n a cold aisle and away from the exhaust of other

systems.

• Ensure that all of the fan tray and power supply modules have the same direction of airflow as

follows (the switch supports only one airflow direction for all modules):

–

Port-side intake airflow modules have black stripes.

–

Port-side exhaust airflow modules have no colored stripes.

Note If the switch is powered up with modules that hav e different airflow directions, you need to shut

down the switch before replacing the modules with the wrong airflow direction.

Grounding the System

Proper Grounding Guidelines

Grounding is one of the most important parts of equipment installation. Proper grounding practices ensure that the buildings and the installed equi pmen t within th em 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. Table 2-3 lists some general grounding practice guidelines.

Table 2-3 Proper Grounding Guidelines

Environment

Commercial building is subjected to direct lightning strikes.

For example, some places in the United States, such as Florida, are subject to more lightning strikes than other areas.

Commercial building is located in an area where lightning storms frequently occur but is not subject to direct lightning strikes.

Commercial building contains a mix of information technology equipment and industrial equipment, such as welding.

Existing commercial building is not subject to natural environmental noise or man-made industrial noise. This building contains a standard office environment. This installation has a history of malfunction due to electromagnetic noise.

Electromagnetic Noise Severity Level Grounding Recommendations

Low Electromagnetic noise problems

are not anticipated, but installing a grounding system in a new building is often the least expensive route and the best way to plan for the future. Grounding recommendations should be followed as closely as possible.

Low Electromagnetic noise problems

are not anticipated, but installing a grounding system is always recommended. 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 devices are completely installed and that the capti ve 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 installa tions.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when modules or other Field Replaceable Units (FRUs) are improperly handled, results in intermittent or complete failures. Devices 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

Cisco Nexus 2000 Series FEX chassis are equipped with a banana plug connector (identified by the ground symbol next to the connector) somewhere on the port side exhaust 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 FR Us 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.

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

a. If you are using the ESD wrist strap supplied with the 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 ba re 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 yo ur bare skin.

spot (unpainted surface) on the rack. We recommend that you touch t he clip to an unpain ted rack rai l so that any built-up static charge is then safely dissipated to the entire rack.

Figure 2-2):

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.

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.

In addition, follow these guidelines when handling these devices:

• Handle carriers by available handles or edges only; avoid touching the printed circuit boards or

connectors.

• Place a removed component board-side-up on an antistatic surface or in a static-shielding container.

If you plan to return the component to the factory, immediately place it in a static-shielding container.

• Never attempt to remove the printed circuit board from the metal carrier.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be

between 1 and 10 megohm (Mohm).

Chapter 2 Installing a Cisco Nexus Fabric Extender

Establishing the System Ground

This section describes how to connect a system ground to the Cisco Nexus 2000 and 2 300 Series FEX s.

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

You must use the system (NEBS) ground on AC-po wered systems if you are installing thi s equipment in a U.S. or European Central Office.

The system (NEBS) ground provides additional grounding for EMI shielding requirements and grounding for the lo w-v oltage su pplies (DC-DC co nverters) on the devices and is intended to satisfy the T el cordi a Technologies NEBS requirements for supplemental bonding and grounding connections. You must observe the following system grounding guidelines for your chassis:

• You must install the system (NEBS) ground connection with any other rack or system power gr ound

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

• You must connect both the system (NEBS) ground connection and the power supply ground

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

• You do not need to power down the chassis because the Cisco Nexus FEX is equipped with A C-input

power supplies.

Grounding the System

Required Tools and Equipment

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

• Grounding lug—A two-hole standard ba rrel lug that supports up to 6 A WG wire. Th is lug is supplied

as part of accessory kit.

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

the accessory kit.

• Grounding wire—Not supplied as part of 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 device 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.

Maintaining SFP+ Transceivers and Cables

You must keep SFP+ transceivers 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 belo w

0.35 dB. Follow these maintenance guidelines:

• SFP+ 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 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.

Chapter 3 Connecting a Cisco Nexus Fabric Extender

• 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.

Troubleshooting Hardware Components

This chapter describes how to identify and resolve problems that might occur with the hardware components of the Cisco Nexus 2000 Series Fabric Ex tender (FEX) or Ci sco Ne xus 2300 Series FEX. I t includes the following sections:

• Overview, pa ge D-1

• SNMP Traps, page D-1

• Device Hardware Guidelines, page D-2

• Contacting Customer Service, page D-3

The key to success when troubleshooting the system hardware is to isolate the problem to a specific system component. The first step is to compare what the system is doing to what it should be doing. Because a startup problem can usually be attributed to a single component, it is more efficient to isolate the problem to a subsystem rather than troubleshoot each separate component in the system.

Problems with the initial power up are often caused by a module that is not firmly connected to the backplane or a power supply that has been disconnected from the power cord connector.

Overheating can also cause problems with the system, though typically only after the system has been operating for an extended period of time. The most common cause of overheating is the failure of a fan tray.

SNMP Traps

You can set SNMP traps to monitor fans, power supplies, and temperature settings, or to test a call home application. Use the following commands to set SNMP traps:

• test pfmtest-SNMP-trap fan

• test pfmtest-SNMP-trap power supply

• test pfmtest-SNMP-trap temp-sensor

Device Hardware Guidelines

Use the recommendations in this section to ensure the proper installation, initialization, and operation of the device. This section includes the following topics:

• Installation, page D-2

• Initialization, page D-2

• Device Operation, page D-2

Installation

When installing the device, follow these best practices:

• Plan your site configuration and prepare the site before installing the chassis.

• Verify that you have the appropriate power su pplies and fan trays for you r chassis configurati on. For

each chassis, each module must have the same airflow direction. Either all modules have front-to-back airflow (no black stripe on the front) or all hav e back-to-front air flow (black stripe on the front). If you have modules that use dif ferent airflo w directions in the same chassis, you will see an error message.

Appendix D Troubleshooting Hardware Components

• Install the chassis following the rack and airflow guidelines in this publication.

• Verify that the chassis and DC power supplies are adequately grounded.

Initialization

When the initial system boot is complete, verify the following:

• Power supplies are supplying power to the system.

• Fan trays are operating normally.

• The system software boots successfully . See the Cisco Ne xus 2000 Series Fabric Extender Software

Configuration Guide for information about booting the system and initial configuration task.

Device Operation

To ensure proper operation of your device, do the following:

• Make a copy of the running configuration to CompactFlash for a safe backup.

• Always enter the copy running-config startup-config command after you modify the running

configuration and ensure that the system is operating properly.

• Never use the init system command unless you understand that you will lose the running and startu p

configuration as well as the files stored on bootflash:.

D-2

• Keep backup copies of the running kickstart and the system images on CompactFlash.

Contacting Customer Service

If you are unable to solve a startup problem after using the troubleshooting suggestions in this chapter, contact a customer service representative for assistance and additional instructions. Before you call, hav e the following information ready to help your service provider assist you as quickly as possible:

• Date that you received the device

• Chassis serial number (located on a label on the right of the rear panel of the chassis)

• Type of software and release number

• Maintenance agreement or warranty information

• Brief description of the problem

• Brief explanation of the steps that you have already taken to isolate and resolve the problem
