THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL
STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT
WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.
THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT
SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE
OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.
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.
• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits
controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

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.

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.

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.

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.

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 (N2200-P-BLNK) to cover the empty slot. Figure 1-15 on page 1-14 shows a blank
power supply filler panel.
For power supply specifications, see Table B-1 on page B-2. To replace a power supply, see the
“Removing and Installing Power Supplies” section on page 3-17.
Fan Trays
The Cisco Nexus 2248PQ FEX has one fan tray that is hot swappable during operations. Depending on
whether there is a cold aisle in front of or in back of the chassis, you can order front-to-back airflow or
back-to-front airflow for the fan tray and the power supplies in the same chassis. Table 1-10 lists the part
numbers for each of the fan trays that you can use with this chassis.

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)

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 a fully dedicated 10-Gbps bandwidth through a M1 Series 32-port 10-Gigabit Ethernet I/O module
(either the N7K-M132XP-12 or N7K-M132XP-12L), connect each FEX to one port in a set of four
shared ports on the module (you connect each set of shared ports to one FEX). If you are using the M2
Series 24-port, 10-Gigabit Ethernet I/O module (N7K-M224XP-23L), you can connect the FEX to any
of its ports for a fully dedicated bandwidth. If you are using the F2 Series 48-port, 10-Gigabit Ethernet
I/O module (N7K-F248XP-25), use the connectivity rule order (connect the same port numbers for each
port group (for example, if you connect ports 1 and 2 of a port-group, then connect the same ports of
another port group).
For information about the transceivers and connectors that you can use with these ports, see the
“Transceivers and Connectors Supported by the Cisco Nexus 2248TP-E FEX” section on page 2-9.
Power Supplies for the Cisco Nexus 2248TP-E FEX
The Cisco Nexus 2200 Series FEX chassis have two slots for front-end AC or DC power supplies that
have front-to-back or back-to-front airflow. These chassis are fully functional with one power supply,
but you can install a second power supply for power redundancy. If you have only one power supply in
the chassis, install a blank filler panel (N2200-P-BLNK) to maintain the designed airflow in the chassis.
You can install any of the following power supplies in those two bays:

For a fully dedicated 10-Gbps bandwidth through a M1 Series 32-port 10-Gigabit Ethernet I/O module
(either the N7K-M132XP-12 or N7K-M132XP-12L), connect each FEX to one port in a set of four
shared ports on the module (you connect each set of shared ports to one FEX). If you are using the M2
Series 24-port, 10-Gigabit Ethernet I/O module (N7K-M224XP-23L), you can connect the FEX to any
of its ports for a fully dedicated bandwidth. If you are using the F2 Series 48-port, 10-Gigabit Ethernet
I/O module (N7K-F248XP-25), use the connectivity rule order (connect the same port numbers for each
port group (for example, if you connect ports 1 and 2 of a port-group, then connect the same ports of
another port group).

Installation Options
The Cisco Nexus 2000 Series 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
– 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 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.
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.

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.

Existing commercial building is Low
not subject to natural
environmental noise or
man-made industrial noise. This
building contains a standard
office environment.
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.

Grounding the System
Send document comments to nexus5kdocs@cisco.com
Note
•
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.
This system ground is also referred to as the network equipment building system (NEBS) ground.
•
Note
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.
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
b.
The spring clip jaws do not open wide enough to fit directly over the head of the lug screw
or the lug barrel.
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:
Caution
•
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.
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

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.

Site Preparation Checklist
Planning the location and layout of your equipment rack or wiring closet is essential for successful
device operation, ventilation, and accessibility. Table G-1 lists the site planning tasks that we
recommend completing before installing the Cisco Nexus 2000 Series Fabric Extender.
Consider heat dissipation when sizing the air-conditioning requirements for an installation. See
Table B-2 on page B-5 for the environmental requirements and the “Power Specifications” section on
page B-1 for power and heat ratings.
