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.

Chassis

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

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

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.

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

Using a Fabric Extender with a Cisco Nexus 7000 Series Switch

This chapter describes the Cisco Nexus 2200 Platform Fabric Extender (FEX) chassis and the components that you can connect to a Cisco Nexus 7000 Series switch.

This chapter includes the following sections:

• Information About Using a Fabric Extender with a Cisco Nexus 7000 Series Switch, page 2-1

• Cisco Nexus 2248TP-E FEX, page 2-2

• Cisco Nexus 2248TP FEX, page 2-11

• Cisco Nexus 2232TM FEX, page 2-15

• Cisco Nexus 2232PP FEX, page 2-20

• Cisco Nexus 2224TP FEX, page 2-25

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 rack-mount kit shipped with the device

–

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

Chapter 3 Installing a Cisco Nexus 2000 Series Fabric Extender

• 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 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.

• 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 2000 Series 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 2000 Series 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 air intake is not located where the FEX would take in exhaust air from other systems.

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

Installation.”

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 is adequately grounded. If the device is not mounted in a grounded rack, we

recommend connecting both the system ground on the chassis and the power supply ground to an earth ground.

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

Specifications.” If available, you can use an uninterrupted power supply (UPS) to protect against

power failures.

• 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. Tab l e 3 -2 lists some general grounding practice guidelines.

Level Grounding Recommendations

Medium Determine source and cause of

noise if possible, and mitigate as closely as possible at the noise source or reduce coupling from the noise source to the affected equipment. Grounding recommendations must be closely followed.

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 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.

• 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

Grounding the System

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.

Grounding the System

• 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.

Warning

Caution We recommend that you ground the chassis, even if the rack is already grounded.

Caution You must ground all power supplies. The receptacles of the AC power cables used to provide power to

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

Statement 1046

the chassis must be the grounding type, and the grounding conductors should connect to protective earth ground at the service equipment.
