The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco???s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco???s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

???Turn the television or radio antenna until the interference stops.

???Move the equipment to one side or the other of the television or radio.

???Move the equipment farther away from the television or radio.

Information About Using a Fabric Extender with a Cisco Nexus 5000 Series Switch

The Cisco Nexus 2000 Series Fabric Extenders (FEXs) support Gigabit Ethernet and 10-Gigabit Ethernet environments while allowing transparent migration to 10-Gigabit Ethernet virtual machine aware unified fabric technologies. The Cisco Nexus 2000 Series FEXs behave as remote I/O modules for a parent Cisco Nexus 5000 Series 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 2000 Series FEX forwards all the traffic to the parent Cisco Nexus 5000 Switch over 10-Gigabit Ethernet uplinks. Passing all traffic to the parent switch allows traffic to be shaped according to policies established on the parent Cisco Nexus 5000 Series switch with a single point of management.

Cisco Nexus 2248TP-E

The Cisco Nexus 2248TP-E is a stackable 1 RU 17.2-inch (45 cm) deep FEX that supports 48 1000-TX host-facing (downlink) ports and 4 10-Gigabit SFP+ network-facing (uplink) ports. You can order it with front-to-back or back-to-front air cooling, and with AC or DC power supplies.

Cisco Nexus 2000 Series Hardware Installation Guide

Chapter 1 Using a Fabric Extender with a Cisco Nexus 5000 Series Switch

Cisco Nexus 2248TP-E

You can use this FEX with the Cisco Nexus 5000 Series switch. The Cisco Nexus 2248TP-E is managed and configured by the upstream switch. The FEX software ships with the Cisco Nexus 5000 Series switch software. The FEX downloads the software image from the switch the same way that a module would download it from the supervisor in a modular chassis.

This section includes the following topics:

???Chassis, page 1-2

???Ports, page 1-3

???Power Supplies, page 1-3

???Fan Trays, page 1-7

???Supported Transceivers and Cables, page 1-9

Chassis

The Cisco Nexus 2248TP-E FEX chassis has a height of 1.72 inches (4.37 cm), a width of 17.3 inches (43.94 cm), and a depth of 17.7 inches (44.96 cm). It weighs 17.7 pounds (8.0 kg). Its one-rack-unit (1 RU) form factor takes up relatively little space, making it easy to incorporate into rack designs. The FEX is mounted in a standard 19-inch (48.26 cm) rack. All switch ports at the rear of the unit are in close proximity to server ports, and all user-serviceable components are accessible from the front panel.

You can order it with front-to-back or back-to-front air cooling, and with AC or DC power supplies. If you are going to install the chassis with its front end facing the cold aisle, you must order the chassis with front-to-back air flow. If you are going to install the chassis with its back end facing the cold aisle, you must order the chassis with back-to-front airflow.

Figure 1-1 shows the location of the components found on the front of the chassis, and Figure 1-2 shows the location of components found on the rear of the chassis. For information on what the chassis and component LEDs indicate, see Table D-1 on page D-2.

Ports

The Cisco Nexus 2248TP-E FEX supports a total of 48 100/1000BASE-T ports and four 10-Gigabit Ethernet uplinks (SFP+). It provides two types of ports: host-facing downlink ports and network-facing uplink ports. Uplink ports are colored with yellow for connectivity to the upstream parent Cisco Nexus 5000 Series switch.

Power Supplies

The Cisco Nexus 2248TP-E FEX chassis has two bays for front-end AC or DC power supplies. This chassis is fully functional with one power supply, but you can install a second power supply for power redundancy. The power supply is hot swappable during operations.

Table 1-1 lists the power supplies that you can order with the Cisco Nexus 2248TP-E FEX.

239932

You can order the Cisco Nexus 2248TP-E FEX with AC power supplies that have front-to-back or back-to-front airflow for cooling or DC power supplies that offer front-to-back airflow. The back-to-front airflow components have a black stripe on their front surface for easy visual identification. The front-to-back airflow components do not have a black stripe.

Caution Be sure that all of the power supply and fan tray modules in the same chassis have the same airflow direction and that the air intake for those modules is positioned on a cool aisle. If you install a module that uses a different direction of airflow from the other modules in your system, you will see an error message. If you position a chassis with its modules taking cooling air from a warm aisle, the switch can reach an overtemperature state and shut down.

If one power supply is installed in the chassis, but the other power supply slot is empty, you should use a blank filler panel (part number N2200-P-BLNK) to cover the empty slot. Figure 1-7 shows a blank power supply filler panel.

Chapter 1 Using a Fabric Extender with a Cisco Nexus 5000 Series Switch

Cisco Nexus 2248TP

You can order the Cisco Nexus 2248TP FEX with AC power supplies that have front-to-back or back-to-front airflow for cooling or DC power supplies that offer front-to-back airflow. The back-to-front airflow components have a black stripe on their front surface for easy visual identification. The front-to-back airflow components do not have a black stripe.

Caution Be sure that all of the power supply and fan tray modules in the same chassis have the same airflow direction and that the air intake for those modules is positioned on a cool aisle. If you install a module that uses a different direction of airflow from the other modules in your system, you will see an error message. If you position a chassis with its modules taking cooling air from a warm aisle, the switch can reach an overtemperature state and shut down.

If one power supply is installed in the chassis, but the other power supply slot is empty, you should use a blank filler panel (part number N2200-P-BLNK) to cover the empty slot. Figure 1-15 shows a blank power supply filler panel.

Information About Using a Fabric Extender with a Cisco Nexus 7000 Series Switch

You can extend the Cisco Nexus 7000 Series switch architecture by connecting up to 32 FEXs as remote I/O modules. Depending on which FEX model that you connect to the switch, the FEX provides top-of-the-rack connectivity for up to 48, 32, or 24 hosts, and it becomes an extension of the parent Cisco Nexus 7000 Series switch fabric, with the FEX and the switch becoming a virtual modular system. The FEX forwards all 100/1000 Ethernet or 1- and 10-Gigabit Ethernet traffic from the hosts to the switch over 10-Gbps uplinks. Traffic flows from the switch to the FEX over the 10-Gbps uplinks and to the individual hosts over 100/1000 Ethernet or 1- and 10-Gigabit Ethernet downlinks.

You connect a FEX uplink port to the Cisco Nexus 7000 Series switch through one of the following Ethernet I/O modules installed in the switch:

???F2 Series 48-port 1 or 10-Gigabit Ethernet I/O module (N7K-F248XP-25)

???M1 Series 32-port 10-Gigabit Ethernet I/O module (N7K-M132XP-12)

???M1 Series 32-port 10-Gigabit Ethernet I/O module with XL option (N7K-M132XP-12L)

???M2 Series 24-port 10-Gigabit Ethernet I/O module (N7K-M224XP-23L)

The Cisco Nexus 2248TP-E FEX (N2K-C2248TP-E) is a stackable 1-RU FEX that has 48 100/1000 Ethernet host-facing (downlink) ports and four 10-Gigabit Ethernet network-facing (uplink) ports. It requires a 19-inch (48.26 cm) rack for its installation. Table 2-1 lists its physical characteristics.

1. Measured with two power supplies and one fan module installed.

You can order the Cisco Nexus 2248TP-E with front-to-back (port-side exhaust) or back-to-front (port-side intake) airflow and with AC or DC power supplies. If you are going to install the port side in a hot aisle, then order front-to-back airflow for the fan trays and power supplies. If you are going to install the port side in the cold aisle, order back-to-front airflow for the fan trays and power supplies.

Note For visual identification, back-to-front airflow power supplies and fan trays have a black stripe across their front, and front-to-back airflow modules do not have a black stripe across their front. All of the power supplies and fan trays must have the same direction of airflow for the components to properly function (all of these components must either have a black stripe or all of the components must not have a black stripe).

The front of the Cisco Nexus 2248TP-E FEX chassis has one or two power supplies, a fan tray, and two chassis LEDs as shown in Figure 2-1. This FEX model requires one power supply, but if you want power redundancy, you must install a second power supply.

For instructions on installing the device using the rack-mount kit shipped with the device, see the ???Installing the Cisco Nexus 2000 Series Fabric Extender Chassis in a Cabinet or Rack??? section on page 3-5.

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 2000 Series FEX is from the front to the back or the back to the front. To ensure proper airflow, follow these guidelines:

???Position the chassis so that its air intake side (front side for front-to-back airflow or back side for back-to-front airflow) is in a cold aisle. Otherwise, an overtemperature 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 2000 Series FEX, it is also possible for air to recirculate across the top and bottom of the chassis in a partially populated rack.

???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 (front-to-back airflow) or all of the modules should have a black stripe (back-to-front airflow).

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

Grounding the System

Se n d d o c u m en t c o m m e n t s t o n e x u s5 k d o c s @ c is c o . c o m

Grounding the System

This section describes the need for system grounding and explains how to prevent damage from electrostatic discharge.

This section includes the following topics:

???Proper Grounding Guidelines, page 3-9

???Preventing Electrostatic Discharge Damage, page 3-10

???Establishing the System Ground, page 3-13

???Required Tools and Equipment, page 3-13

Proper Grounding Guidelines

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. Table 3-2 lists some general grounding practice guidelines.

Table 3-2 Proper Grounding Guidelines

Cisco Nexus 2000 Series Hardware Installation Guide

Chapter 3 Installing a Cisco Nexus 2000 Series Fabric Extender

Grounding the System

Se n d d o c u m en t c o m m e n t s t o n e x u s5 k d o c s @ c is c o . c o m

Table 3-2 Proper Grounding Guidelines

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 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.

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.

Chapter 3 Installing a Cisco Nexus 2000 Series Fabric Extender

Grounding the System

Se n d d o c u m en t c o m m e n t s t o n e x u s5 k d o c s @ c is c o . c o m

???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 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 does not have the system ground attached, you must install the system ground lug. See the???Establishing the System Ground??? section on page 3-13 for installation instructions and location of the chassis system ground pads.

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 your bare skin as follows:

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 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 the 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 the ground lug screw as follows (see Figure 3-5):

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).

Establishing the System Ground

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

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-powered systems if you are installing this equipment in a U.S. or European Central Office.

The system (NEBS) ground provides additional grounding for EMI shielding requirements and grounding for the low-voltage supplies (DC-DC converters) on the devices and is intended to satisfy the Telcordia 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 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 (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 2000 Series FEX is 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 that supports up to 6 AWG wire. This 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 below 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.

???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 Extender (FEX). It includes the following sections:

???Overview, page E-1

???SNMP Traps, page E-1

???Device Hardware Guidelines, page E-2

???Contacting Customer Service, page E-3

Overview

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 Operation, page E-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 supplies and fan trays for your chassis configuration. 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 have back-to-front airflow (black stripe on the front). If you have modules that use different airflow directions in the same chassis, you will see an error message.

???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 Nexus 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 startup configuration as well as the files stored on bootflash:.

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