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
Switch
The Cisco Nexus 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 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-Gigabit Ethernet
uplinks. Passing all traffic to the parent switch allows traffic to be shaped according to policies
established on the parent Cisco Nexus switch with a single point of management.
Cisco Nexus 2300 Series
The Cisco Nexus 2300 Series FEXs are stackable, hardware capable, 1 RU FEXs that support 48 1/10G
host ports as well as up to 6 40G uplink ports towards the parent switch. The 40G uplinks support bi-di
optics for seamlessly connectivity. The platform has a deep 32MB shared buffer for increased
performance.

The Cisco Nexus 2348TQ provides 48 1/10GBASE-T host ports, while the Cisco Nexus 2348UPQ
provides 48 1/10G host unified ports. The unified ports provide native Fibre Channel as well as 1/10G
Ethernet and FCoE connectivity options.
You can order the platform with port side exhaust or port side intake air cooling. The port side exhaust
cooling model is compatible with data center hot-aisle and cold-aisle designs. This orientation places the
ports on the hot aisle aligned with the server ports. Port side intake airflow is used in network rack
designs in the data center such that the ports face the cold aisle. The Cisco Nexus 2300 Series is built for
non-stop operation, with redundant hot-swappable power supplies and redundant hot-swappable fans.
The Cisco Nexus 2300 Series platform is managed and configured by the upstream switch. The FEX
software ships with the Cisco Nexus 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.
Note For the most current list of supported features, refer to the latest Cisco Nexus 2000 Series Fabric
Extenders Release Notes at every release.

Chassis
The Cisco Nexus 2300 Series platform has a one-rack-unit (1 RU) form factor that 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 fan side panel.
You can order it with port side exhaust or port side intake air cooling, and with AC or DC power supplies.
The port side intake cooling model is intended for installations or deployments where the ports are in
the cold aisle, and the fans and power supplies are in the warm aisle.

Chassis
You can order the Cisco Nexus 2300 Series platform with AC power supplies that have port-side exhaust
or port-side intake airflow for cooling or DC power supplies that offer port-side exhaust and port-side
intake airflow. The port-side intake airflow components have a black stripe on their front surface for easy
visual identification. The port-side exhaust airflow components do not have a black stripe.
Note Colored handles on each power supply clearly indicate the airflow direction.
Caution Be sure that all of the power supply and fan 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 than the other modules in the same switch, the switch can overheat and shut
down. If you position a chassis with its modules taking cooling air from a warm aisle, the switch can
over heat 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 1-11 shows a blank
power supply filler panel.

Cisco Nexus 2248TP
You can order the Cisco Nexus 2248TP FEX with AC power supplies that have port-side exhaust or
port-side intake airflow for cooling or DC power supplies that offer port-side exhaust airflow. The
port-side intake airflow components have a black stripe on their fan side surface for easy visual
identification. The port-side exhaust 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
over heat 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 1-26 shows a blank
power supply filler panel.

Cisco Nexus 2148T
The Cisco Nexus 2148T FEX is a 1 RU device that acts as a remote I/O module on the Cisco Nexus 5000
Series switch. All device configurations are managed on the switch and configuration information is
downloaded through inband communication to the FEX. You can use this FEX with the Cisco Nexus
5000 Series 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.

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 2224TP FEX, page 2-27
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)

Cisco Nexus 2248TP-E FEX
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.
You can order the Cisco Nexus 2248TP-E with port-side exhaust or back-to-front airflow and with AC
or DC power supplies. If you are going to install the port side in a hot aisle, then order port-side exhaust
airflow for all of the fan trays and power supplies. If you are going to install the port side in the cold
aisle, order port-side intake airflow for the fan trays and power supplies.
Note For visual identification, port-side exhaust airflow power supplies and fan trays have a black stripe
across their front, and port-side intake 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.

Note 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

Note 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 FEX” section on page 2-14.

Using a Fabric Extender with a Cisco Nexus 9000
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 9000 Series switch.
This chapter includes the following sections:
•Information About Using a Fabric Extender with a Cisco Nexus 9396PX Switch, page 3-1
•Cisco Nexus 2248TP-E FEX, page 3-1
•Cisco Nexus 2248TP FEX, page 3-10

•Cisco Nexus 2224TP FEX, page 3-25
Information About Using a Fabric Extender with a Cisco Nexus
9396PX Switch
With Cisco NX-OS Release 6.1(2)I2(3) and later releases, you can extend the Cisco Nexus 9396PX
switch architecture by connecting up to six 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 9396PX 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.
Cisco Nexus 2248TP-E FEX
The Cisco Nexus 2248TP-E FEX (N2K-C2248TP-E) is a stackable 1-RU FEX that has 48 100/1000
Ethernet host interfaces (downlink ports for copper RJ-45 connectors) and four 10-Gigabit Ethernet
fabric interfaces (uplink ports for copper/optical SFP+ connectors). This FEX requires a 19-inch
(48.26-cm) rack for its installation. Table 3-1 lists its physical characteristics.

Chapter 3 Using a Fabric Extender with a Cisco Nexus 9000 Series Switch
Cisco Nexus 2248TP-E FEX
You can order the Cisco Nexus 2248TP-E FEX with port-side exhaust or 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
port-side-exhaust airflow for all of the fan trays and power supplies. If you are going to install the port
side in the cold aisle, order port-side-intake airflow for all of the fan trays and power supplies.
Note For visual identification, port-side-intake airflow power supplies and fan trays have a black stripe across
their front, and port-side-exhaust 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 3-1. This FEX model requires one power supply, but if you want power
redundancy, you must install a second power supply.

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 port-side-exhaust or port-side-intake 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:
•AC power supply with port-side-exhaust airflow (N2200-PAC-400W)
•AC power supply with port-side-intake airflow (N2200-PAC-400W-B)
•DC power supply with port-side-exhaust airflow (N2200-PDC-400W)
•DC power supply with port-side-intake airflow (N2200-PDC-350W-B)
Caution Make sure that all of the fan tray and power supply modules use the same airflow direction and have the
same color designation on the front. Otherwise, the switch can over heat and shut down,
Figure 3-4 shows the exterior components on an AC power supply with port-side-exhaust airflow (no
black stripe on the front). Figure 3-5 shows the components on a DC power supply with
port-side-exhaust airflow. Figure 3-6 shows the black stripe used to indicate port-side-intake airflow (in
this case on an AC power supply). Figure 3-7 shows the blank filler panel that you should install in an
open power supply slot if the chassis has only one power supply.

You can order the Cisco Nexus 2248TP FEX 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 port-side-exhaust airflow for the fan trays and power supplies. If you are going to
install the port side in the cold aisle, order port-side-intake airflow for the fan trays and power supplies.
Note For visual identification, port-side-intake airflow fan trays and power supplies have a black stripe across
their front, and port-side-exhaust 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 FEX chassis has one or two power supplies, a fan tray, and two
chassis LEDs as shown in Figure 3-13. This FEX model requires one power supply, but if you want
power redundancy, you must install a second power supply.

Preparing for Installation
Preparing for Installation
This section includes the following topics:
•Installation Options, page 4-2
•Airflow Considerations, page 4-2
•Chassis Weight, page 4-3
•Installation Guidelines, page 4-3
•Required Tools and Equipment, page 4-4
•Unpacking and Inspecting the Cisco Nexus Fabric Extender, page 4-5
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
–
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 4-6.
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 exhaust side for port side exhaust airflow or
back side for port side intake 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 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 (port side exhaust airflow) or all of the modules should have
a black stripe (port side intake airflow).

4-3
Cisco Nexus 2000 Series Hardware Installation Guide
Chapter 4 Installing a Cisco Nexus Fabric Extender
Preparing for Installation
Note If the switch is powered up with modules that have 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.
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 will be located in 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 have different airflow directions, you need to shut
down the switch before replacing the modules with the wrong airflow direction.

Cisco Nexus 2000 Series Hardware Installation Guide
Chapter 4 Installing a Cisco Nexus Fabric Extender
Preparing for Installation
•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.
Caution Avoid UPS types that use ferroresonant technology. These UPS types can become unstable
with systems such as the Cisco Nexus FEX, which can have substantial current draw
fluctuations because of fluctuating data traffic patterns.
•Ensure that circuits are sized according to local and national codes. For North America, the power
supply requires a 15-A or 20-A circuit.
Caution To prevent loss of input power, ensure the total maximum loads on the circuits supplying
power to the device are within the current ratings for the wiring and breakers.
•Use the following screw torques when installing the device:
–
Captive screws: 4 in-lb
–
M3 screws: 4 in-lb
–
M4 screws: 12 in-lb
–
10-32 screws: 20 in-lb
–
12-24 screws: 30 in-lb
Required Tools and Equipment
Before beginning the installation, ensure that the following items are ready:
•Number 1 and number 2 Phillips screwdrivers with torque capability
•3/16-inches flat-blade screwdriver
•Tape measure and level
•ESD wrist strap or other grounding device
•Antistatic mat or antistatic foam
The following additional items (not found in the accessory kit) are required to ground the chassis:
•Grounding cable (6 AWG recommended), sized according to local and national installation
requirements; the required length depends on the proximity of the Cisco Nexus FEX to proper

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 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 4-3
lists some general grounding practice guidelines.
Table 4-3 Proper Grounding Guidelines
Environment
Electromagnetic Noise Severity
Level Grounding Recommendations
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.
High All lightning protection devices
must be installed in strict
accordance with manufacturer
recommendations. Conductors
carrying lightning current
should be spaced away from
power and data lines in
accordance with applicable
recommendations and codes.
Best grounding
recommendations must be
closely followed.
Commercial building is located
in an area where lightning
storms frequently occur but is

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.

Cisco Nexus 2000 Series Hardware Installation Guide
Chapter 4 Installing a Cisco Nexus Fabric Extender
Grounding the System
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 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 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.
New commercial building is not
subject to natural environmental
noise or man-made industrial
noise. This building contains a
standard office environment.
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.
Existing commercial building is
not subject to natural
environmental noise or
man-made industrial noise. This
building contains a standard
office environment.
Low Electromagnetic noise problems
are not anticipated, but
installing a grounding system is

Chapter 4 Installing a Cisco Nexus Fabric Extender
Grounding the System
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 4-13 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 4-1 and
Figure 4-2):
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.

Grounding the System
Establishing the System Ground
This section describes how to connect a system ground to the Cisco Nexus 2000 and 2300 Series FEXs.
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 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.

Removing and Installing the Fan Tray
The Cisco Nexus 2200 Series FEXs, and Cisco Nexus 2148T FEX, use a fan tray. The fan tray is
designed to be removed and replaced while the system is operating without causing an electrical hazard
or damage to the system, if the replacement is performed within 1 minute.
Caution Be sure that the fan tray that you are installing has the same airflow direction as the other fan tray and
power supply modules in the same chassis. Either all of the modules must have port-side exhaust airflow
(a blue or no color on the front of the module) or all of the modules must have port-side intake airflow
(red or black color on the front of the module). If the modules have different airflow directions in the
same chassis, an error condition occurs, the switch can over heat, and the switch can shut down.
Note If you power up a FEX with power supply and fan tray modules that have different directions of airflow,
an error condition will occur and the switch can over heat and shut down. With this error condition, you
must shut down the switch to replace the modules that do not take in cool air from the cold aisle. After
you ensure that all of the modules have the same direction of airflow and take in cooling air from the
cold aisle, you can power up the FEX.

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) or Cisco Nexus 2300 Series FEX. It
includes the following sections:
•Overview, page D-1
•SNMP Traps, page D-1
•Device Hardware Guidelines, page D-2
•Contacting Customer Service, page D-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 Hardware Guidelines
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 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.

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, have
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
