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.

10/100/1000 Ethernet Ports
The 10/100/1000 Ethernet ports use RJ-45 connectors with Ethernet pinouts. The maximum cable length
is 328 feet (100 meters). The 100BASE-TX and 1000BASE-T traffic requires Category 5, Category 5e,
or Category 6 unshielded twisted pair (UTP) cable. The 10BASE-T traffic can use Category 3 or
Category 4 UTP cable.
For information about the 10/100/1000 Ethernet port connections and specifications, see the
“10/100/1000 Ethernet Port Connections” section on page 2-28 and Appendix B, “Connector and Cable
Specifications.”
PoE+ Ports
The PoE+ ports use the same connectors as described in the previous section and provide this support.
•
Support for IEEE 802.3af compliant powered devices (up to 15.4 W)
•
Support for IEEE 802.3at compliant powered devices (up to 30 W)
•
Support for Cisco enhanced PoE
•
Support for prestandard Cisco powered devices

Product Overview
Front Panel Description
•
Configuration for StackPower PoE+. When the switch internal power supply module(s) cannot
support the total load, StackPower configurations allow the switch to leverage power available from
other switches (only Catalyst 3750-X switches)
•
Configurable support for Cisco intelligent power management, including enhanced power
negotiation, power reservation, and per-port power policing
Depending on the installed power supply modules, each port can deliver up to 30 W of PoE+. See
Table 1-17 for the power supply matrix that defines the available PoE and PoE+ power per port.
Note
The output of the PoE+ circuit has been evaluated as a Limited Power Source (LPS) per IEC 60950-1.
For information about power supply modules, PoE+ port connections, and PoE+ specifications, see the
“Power Supply Modules” section on page 1-17, the “PoE+ Port Connections” section on page 2-28, and
Appendix B, “Connector and Cable Specifications.”
Network Modules
The switch has one hot-swappable network module that provides SFP and SFP+ uplink ports to connect
to other devices. You must insert the network module during switch operation. Operating the switch
without a network module is not supported. A blank module is available.
The switch generates logs when you insert or remove a network module with SFP ports.

Network Modules
Network Module1
Description
Blank
This module has no uplink ports.
1-Gigabit Ethernet
This module has four 1-Gigabit SFP module slots. Any combination of standard
SFP modules are supported. SFP+ modules are not supported.
If you insert an SFP+ module in the 1-Gigabit network module, the SFP+
module does not operate, and the switch logs an error message.
10-Gigabit Ethernet
This module has four slots. Two slots support only 1-Gigabit SFP modules, two
slots support either 1-Gigabit SFP or 10-Gigabit SFP+ modules.
The four slots are grouped as two pairs with each pair consisting of one SFP slot
and one SFP+ slot. Each pair supports either two 1-Gigabit SFP modules or one
10-Gigabit SFP+ module. A 10-Gigabit SFP+ module cannot operate at the same
time as the corresponding 1-Gigabit SFP module in the pair.
Supported combinations of SFP and SFP+ modules:
•
Slots 1, 2, 3, and 4 populated with 1-Gigabit SFP modules.
•
Slots 1 and 2 populated with 1-Gigabit SFP modules and Slot 4 populated
with one 10-Gigabit SFP+ module.
•
Slot 2 populated with one 10-Gigabit SFP+ module and Slots 3 and 4
populated with 1-Gigabit SFP modules.
•
Slot 2 and Slot 4 each populated with 10-Gigabit SFP+ modules.
A 10-Gigabit SFP+ module takes precedence over a 1-Gigabit SFP module
except when an SFP module is first inserted in Slot 1 and has link. When you
insert an SFP+ module in Slot 2, the SFP in Slot 1 retains link. The SFP+ module
in Slot 2 does not operate.
When the SFP module in Slot 1 is shutdown, loses link, or is removed, the SFP+
module in Slot 2 becomes operational. At this point, the SFP module in Slot 1
will not become operational under any circumstance for as long as an SFP+
module remains in Slot 2 whether it is link up or not.
The same precedence applies to Slots 3 and 4.
1. All network modules are hot-swappable.
For information about the network modules, see the “Installing a Network Module in the Switch” section
on page 2-23. For cable specifications, see Appendix B, “Connector and Cable Specifications.”
SFP and SFP+ Modules
The switch-Gigabit Ethernet SFP and SFP+ modules provide copper or fiber-optic connections to other
devices. These transceiver modules are field-replaceable, providing the uplink interfaces when installed
in an SFP module slot. The SFP modules have LC connectors for fiber-optic connections or RJ-45
connectors for copper connections.

Port LEDs and Modes
Each Ethernet port and 10-Gigabit Ethernet module slot has a port LED. These port LEDs, as a group or
individually, display information about the switch and about the individual ports. The port mode
determines the type of information shown by the port LEDs. Table 1-8 lists the mode LEDs and their
associated port modes and meanings.
To select or change a mode, press the Mode button until the desired mode is highlighted. When you
change port modes, the meanings of the port LED colors also change. Table 1-9 explains how to interpret
the port LED colors in different port modes.

The stack LED shows the sequence of member switches in a stack. Up to nine switches can be members
of a stack. The first nine port LEDs show the member number of a switch in a stack. Figure 1-3 shows
the LEDs on the first switch, which is stack member number 1. For example, if you press the Mode
button and select Stack, the LED for port 1 blinks green. The LEDs for ports 2 and 3 are solid green, as
these represent the member numbers of other switches in the stack. The other port LEDs are off because
there are no more members in the stack.

Power Supply Modules
The 24- and 48-port switches are powered through one or two internal power supply modules. The
“Switch Power Supply Modules” section on page 1-17 and Table 1-16 describe the supported power
supply modules.
Switch Power Supply Modules
The switch has two internal power supply module slots. You can use two AC modules, two DC modules,
a mixed configuration of one AC and one DC power supply module, or one power supply module and a
blank module.
The switch can operate with either one or two active power supply modules or with power supplied by
an XPS-2200. A Catalyst 3750-X switch that is in a StackPower stack can operate with power supplied
by other switches in the stack.
Table 1-1 and Table 1-2 show the power supply modules that ship with each switch model. All power
supply modules (except the blank modules) have internal fans. All switches ship with a blank power
supply module in the second power supply slot.
Caution
Do not operate the switch with one power supply module slot empty. For proper chassis cooling, both
power supply module slots must be populated.
The 350-W and 715-W AC power supply modules are autoranging units that support input voltages
between 100 and 240 VAC. The 1100-W power supply module is an autoranging unit that supports input
voltages between 115 and 240 VAC. The 440-W DC power supply module has dual input feeds (A and
B) and supports input voltages between 36 and 72 VDC. The output voltage range is 51–57 V.
Each AC power supply module has a power cord for connection to an AC power outlet. The 1100-W and
715-W modules use a 16-AWG cord (only North America). All other modules use an 18-AWG cord. The
DC-power supply module must be wired to a DC-power source.
The XPS-2200 powers connected switches when the power supply is removed or fails. When a new
switch power supply is installed, the switch software polls the device. The switch power supply again
provides power, and the XPS-2200 is available to power other devices.
Table 1-16 shows the power supply modules available for Catalyst 3750-X and 3560-X switches and
power supply configurations based on switch models.

configuration_guides_list.html
StackPower Connector (Catalyst 3750-X Switches)
The Catalyst 3750-X switches have a StackPower connector for use with Cisco StackPower cables to
configure a switch power stack that includes up to four switches. By adding an XPS-2200 expandable
power system, you can configure a power stack that comprises up to nine switches. A switch power stack
can be configured in redundant or power-sharing mode.
You can order these StackPower cables from your Cisco sales representative:
•
CAB-SPWR-30CM (0.3-meter cable)
•
CAB-SPWR-150CM (1.5-meter cable)
For details about connecting StackPower cables and StackPower guidelines, see the “Planning a
StackPower Stack (Catalyst 3750-X Switches)” section on page 2-8.
Management Ports
Ethernet Management Port
You can connect the switch to a host such as a Windows workstation or a terminal server through the
10/100 Ethernet management port or one of the console ports (see Figure 1-5 and Figure 1-6). The
10/100 Ethernet management port connection uses a RJ-45 crossover or straight-through cable. The
RJ-45 console port connection uses the supplied RJ-45-to-DB-9 female cable. The USB console port
uses a USB type-A-to-USB 5-pin mini-Type B cable.

USB Mini-Type B Port
The switch provides a USB mini-Type B console connection on the front panel, and the RJ-45 console
port on the switch rear panel. Console output is always active on both connectors, but console input is
active on only one connector at a time, with the USB connector taking precedence over the RJ-45
connector.
Use a USB type-A-to-USB 5-pin mini-Type B cable to connect a PC or other device to the switch. The
required USB cable is included in the optional accessory kit, (part number 800-33434).
The connected device must include a terminal emulation application.
Windows PCs need a driver for the USB port. See the “Installing the Cisco Microsoft Windows USB
Device Driver” section on page C-3 for installation instructions.
When the switch detects a valid USB connection to a powered device, input from the Ethernet connection
is immediately disabled, and input from the USB console is enabled. Removing the USB connection
immediately reenables input from the Ethernet connection. An LED on the switch front panel (see
Figure 1-2) is green when the USB console connection is enabled.
The switch provides a configurable inactivity timeout that reactivates the RJ-45 console if no input
activity has occurred on the USB console for a specified time period. After the USB console has been
deactivated due to a timeout, you can restore its operation by disconnecting and reconnecting the USB
cable. You can disable USB console operation by using Cisco IOS commands. See the switch software
configuration guide for details.

Chapter 2
Switch Installation
Planning a Switch Data Stack (Catalyst 3750-X Switches)
•
When connecting or disconnecting the power cord on a switch that is installed above or below a
1100-W power supply-equipped switch, you might need to remove the module from the switch to
access the power cord.
•
Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent
lighting fixtures. Make sure that the cabling is safely away from other devices that might damage
the cables.
•
For copper connections on Ethernet ports, cable lengths from the switch to connected devices can
be up to 328 feet (100 meters).
•
For cable requirements for SFP+ module connections, see the “Cable and Adapter Specifications”
section on page B-5. Each port must match the wave-length specifications on the other end of the
cable, and the cable must not exceed the minimum cable length.
•
Operating environment is within the ranges listed in Appendix A, “Technical Specifications.”
•
Airflow around the switch and through the vents is unrestricted.
•
Temperature around the unit does not exceed 113°F (45°C). If the switch is installed in a closed or
multirack assembly, the temperature around it might be greater than normal room temperature.
•
Cisco Ethernet Switches are equipped with cooling mechanisms, such as fans and blowers. However,
these fans and blowers can draw dust and other particles, causing contaminant buildup inside the
chassis, which can result in system malfunction. You must install this equipment in an environment
as free from dust and foreign conductive material (such as metal flakes from construction activities)
as is possible.
These standards provide guidelines for acceptable working environments and acceptable levels of
suspended particulate matter:
– Network Equipment Building Systems (NEBS) GR-63-CORE (only with the DC power supply)
– National Electrical Manufacturers Association (NEMA) Type 1
– International Electrotechnical Commission (IEC) IP-20
Tools and Equipment
You need to supply a number-2 Phillips screwdriver to rack-mount the switch. For connecting the
StackWise cables, you need a ratcheting torque screwdriver capable of 5 lbf-in. (80 ozf-in.).

Switch Data Stacking Guidelines
For general concepts and management procedures for switch stacks, see the switch software
configuration guide on Cisco.com. When adding a Catalyst 3750-X switch to a Catalyst 3750 switch
stack, review the Catalyst 3750-X Switch Stack Compatibility Guide on Cisco.com for information about
mixed stack configurations.
Before connecting the switches in a stack, keep in mind these stacking guidelines:
•
Size of the switch and any optional power-supply module. The 1100-W power-supply module is
longer than the other modules. Stacking switches with the same power-supply modules together
makes it easier to cable the switches. For switch dimensions, see Appendix A, “Technical
Specifications.”
•
Length of cable. Depending on the configurations that you have, you might need different-sized
cables. If you do not specify the length of the StackWise cable, the 0.5-meter cable is supplied. If
you need the 1-meter cable or the 3-meter cable, you can order it from your Cisco supplier. For cable
part numbers, see the “StackWise Ports” section on page 1-16. The “Data Stack Cabling
Configurations” section on page 2-5 provides examples of recommended configurations.
•
For rack-mounted switch stacks connected to the XPS-2200, review this recommended sequence of
events:
– If you are using the XPS-2200, install the XPS first at the bottom of the stack. If needed, allow
one RU space between the XPS and the first switch above to provide room for cabling.
– Connect the 12-pin XPS cables to the XPS-2200.
– Rack-mount the switches. If you have the optional 1100-W power-supply module, first mount
the switch before installing the power-supply module.
– Connect the XPS cable to the first switch above the XPS-2200. Connect the stack cables to the
first switch above the XPS.
– Connect the XPS cable to the second switch above the XPS-2200. Connect the stack cables to
the next switch above the XPS.
– Repeat until all switches are connected.
•
For rack-mounted switch stacks that are members of a StackPower stack as well as a data stack, see
the “Planning a StackPower Stack (Catalyst 3750-X Switches)” section on page 2-8.
Data Stack Cabling Configurations
Figure 2-1 is an example of a recommended configuration that uses the supplied 0.5-meter StackWise
cable. In this example, the switches are stacked in a vertical rack or on a table. This configuration

Figure 2-6 and Figure 2-7 show data stacks of Catalyst 3750-X switches with failover conditions. In
Figure 2-6, the StackWise cable is bad in link 2. Therefore, this stack provides only half bandwidth and
does not have redundant connections. In Figure 2-7, link 2 is bad. Therefore, this stack partitions into
two stacks, and the top and bottom switches become stack masters.

Power On Sequence for Switch Data Stacks
Consider these guidelines before you power on the switches in a stack:
•
The sequence in which the switches are first powered on might affect the switch that becomes the
stack master.
•
If you want a particular switch to become the stack master, power on that switch first. This switch
becomes the stack master and remains the stack master until a master re-election is required. After
1 minute, power on the other switches in the stack.
•
If you have no preference as to which switch becomes the stack master, power on all the switches in
the stack within 1 minute. These switches participate in the stack master election. Switches powered
on after 1 minute do not participate in the election.
•
Power off a switch before you add it to or remove it from an existing switch stack.
For conditions that can cause a stack master re-election or to manually elect the stack master, see the
“Managing Switch Stacks” chapter in the switch software configuration guide on Cisco.com.
Planning a StackPower Stack (Catalyst 3750-X Switches)
Catalyst 3750-X switches can share power by using the StackPower feature.

StackPower Cabling Configurations, page 2-9

Installing the Switch, page 2-14
StackPower Stacking Guidelines
You can configure a StackPower stack for either power sharing or redundancy. In power-sharing mode,
the power of all the power supplies in the stack is aggregated and distributed among the stack members.
In redundant mode, when the total power budget of the stack is calculated, the wattage of the largest
power supply is not included. That power is held in reserve and used to maintain power to switches and
attached devices when one power supply fails. Following the failure of a power supply, the StackPower
mode becomes power sharing.
Note
Power-sharing mode is the recommended configuration for Catalyst 3750-X switches. The Catalyst
3560-X switches support only redundant mode.

Switch Installation
StackPower Cabling Configurations
For general concepts and management procedures for switch power stacks, see the switch software
configuration guide on Cisco.com.
Before connecting the switches in a power stack, keep in mind these guidelines:
•
A switch power stack can include a maximum of four switches in a ring topology and nine switches
in a star topology with the XPS-2200.
•
Size of the switch and any optional power supply module. The 1100-W power-supply module is
1.5 inches longer than the other modules, and with the attached cable retention clip, it extends
3 inches from the switch chassis. Stacking switches with the same power-supply modules together
makes it easier to cable the switches. For switch dimensions, see Appendix A, “Technical
Specifications.”
•
Length of cable. Depending on the configurations that you have, you might need different-sized
cables. If you do not specify the length of the StackPower cable, the 0.3 meter cable is supplied. If
you need the 1.5 meter cable, you can order it from your Cisco supplier. For cable part numbers, see
the “StackPower Connector (Catalyst 3750-X Switches)” section on page 1-20. The “StackPower
Cabling Configurations” section on page 2-9 provides examples of recommended configurations.
•
For rack-mounted switch stacks that are members of a data stack and a StackPower stack, see the
“Switch Data Stacking Guidelines” section on page 2-5.
•
For rack-mounted switch stacks connected to the XPS-2200, review this recommended sequence of
events:
– If you are using the XPS-2200, first install the XPS at the bottom of the stack. If needed, allow
one RU space between the XPS and the first switch above to provide room for cabling.
– Connect all the 12-pin XPS cables to the XPS-2200 as needed.
– Rack-mount the switches. If you have the optional 1100-W power-supply module, first
rack-mount the switch before installing the power-supply module.
– Connect the XPS cable to the first switch above the XPS-2200. Connect the stack cables to the
first switch above the XPS.
– Connect the XPS cable to the second switch above the XPS-2200. Connect the stack cables to
the second switch above the XPS.
– Repeat until all devices are connected.
StackPower Cabling Configurations
This section describes the recommended cabling configurations for a StackPower stack. There are two
types of StackPower cables. The cable in Figure 2-8 connects a Catalyst 3750-X switch to another
3750-X switch in a power stack or to an XPS-2200. The cable in Figure 2-9 connects a Catalyst 3750-X
or 3560-X switch to an XPS-2200.
Note
All cable connectors are keyed and color-coded, as are the connections on the switches (See Figure 1-6
and Figure 1-7 on page 1-15).
Both cable types are available in two lengths.

Switch Installation
Connecting to the StackWise Ports (Catalyst 3750-X Switches)
After Installing the Switch
After the switch is installed, you might need to:
•
Configure the switch by running Express Setup to enter the initial switch configuration. For
instructions, see the switch getting started guide that shipped with the switch and also on Cisco.com.
•
Use the CLI setup program to enter the initial switch configuration. See Appendix C, “Configuring
the Switch with the CLI-Based Setup Program.”
•
Connect to the front-panel ports. See the “Installing a Network Module in the Switch” section on
page 2-23 and the “Connecting Devices to the Ethernet Ports” section on page 2-27.
Connecting to the StackWise Ports (Catalyst 3750-X Switches)
Before connecting the StackWise cables, review the “Planning a Switch Data Stack (Catalyst 3750-X
Switches)” section on page 2-4. Always use a Cisco-approved StackWise cable to connect the switches.
Step 1
Remove the dust covers from the StackWise cables and StackWise ports, and store them for future use.
Step 2
Use the window in the StackWise cable to align the connector correctly. Connect it to the StackWise port
on the switch rear panel (Figure 2-22). Using a ratcheting torque screwdriver, tighten the retainer screws
to 5 lbf-in. (80 ozf-in.).

Installing a Network Module in the Switch
These sections describe how to install and remove 1-Gigabit Ethernet and 10-Gigabit Ethernet network
modules that provide uplink ports for the switch or the blank module, which provides no uplink ports.
See the “Network Modules” section on page 1-4.
Note
There must be a supported network module in the network module slot. If no uplink ports are required,
insert a blank network module. An empty slot generates error messages.
The network module is hot-swappable. If you remove a module, replace it with another network module.

Installing a Network Module in the Switch
Use only Cisco network modules and SFP or SFP+ modules with the switch. For information about
supported SFP modules, see the “SFP and SFP+ Modules” section on page 1-5.
For more information about installing, removing, cabling, and troubleshooting network modules, see the
module documentation on Cisco.com. For module cable specifications, see Appendix B, “Connector and
Cable Specifications.”
Tools and Equipment
You need to supply a number-2 Phillips screwdriver.
Installing Network Modules
When installing network modules, observe these general precautions:
•
Do not remove the EMC plug from the 10-Gigabit Ethernet slot until you are ready to install an SFP
or SFP+ module. Either a module or a dust plug must be installed in the slot at all times.
•
Do not remove the dust plugs from the fiber-optic SFP modules or the rubber caps from the
fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the module
ports and cables from contamination and ambient light.
•
Removing and installing a network module can shorten its useful life. Do not remove and insert any
network module more often than necessary.
•
To prevent ESD damage, follow your normal board and component handling procedures when
connecting cables to the switch and other devices.
Step 1
Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.
Step 2
Remove the module from the protective packaging.
Step 3
Remove the 10-Gigabit Ethernet module slot EMC plug and save.
Caution
Verify the correct orientation of your module before inserting it into the slot. Incorrect insertion can
damage the module.
Step 4
Position the module face up to install in the module slot. See Figure 2-25. Slide the module into the
opening until the back of the module faceplate is flush with the switch faceplate. Fasten the captive
screws to secure the network module in place.
Caution
Do not insert or remove a network module with attached fiber-optic cables. A module interface might
change to an error-disabled state when a network module is inserted or removed with connected
fiber-optic cables. If the interface is in an error-disabled state, you can re-enable the interface by using
the shutdown and no shutdown interface configuration commands.

Chapter 2
Switch Installation
Connecting Devices to the Ethernet Ports
10/100/1000 Ethernet Port Connections
The 10/100/1000 Ethernet ports use RJ-45 connectors with Ethernet pinouts. The maximum cable length
is 328 feet (100 meters). The 100BASE-TX and 1000BASE-T traffic requires Category 5, Category 5e,
or Category 6 UTP cable. The 10BASE-T traffic can use Category 3 or Category 4 cable.
The autonegotiation feature is enabled by default on the switch. At this setting, the switch ports
configure themselves to operate at the speed of attached device. If the attached device does not support
autonegotiation, you can explicitly set the switch port speed and duplex parameters. To maximize
performance, either let the ports autonegotiate both speed and duplex, or set the port speed and duplex
parameters on both ends of the connection.
For simplified cabling, the automatic medium-dependent interface crossover (auto-MDIX) feature is
enabled by default on the switch. With auto-MDIX enabled, the switch detects the required cable type
for copper Ethernet connections and configures the interface accordingly. Therefore, you can use either
a crossover or a straight-through cable for connections to a switch 10/100/1000 Ethernet port regardless
of the type of device on the other end of the connection.
See the switch software configuration guide or the switch command reference on Cisco.com for more
information about enabling or disabling autonegotiation and auto-MDIX.
If auto-MDIX is disabled, use the guidelines in Table 2-3 to select the correct cable for connecting the
switch 10/100/1000 Ethernet ports to other devices. See the “Cable and Adapter Specifications” section
on page B-5 for cable-pinout descriptions.

1. 100BASE-TX and 1000BASE-T traffic requires twisted four-pair, Category 5, Category 5e, or
Category 6 cable. 10BASE-T traffic can use Category 3 or Category 4 cable.
PoE+ Port Connections
The 10/100/1000 PoE ports have the same autonegotiation settings and cabling requirements that are
described in the “10/100/1000 Ethernet Port Connections” section on page 2-28. These ports can provide
PoE or PoE+ inline power.
PoE inline power supports devices compliant with the IEEE 802.3af standard, as well as prestandard
Cisco IP Phones and Cisco Aironet Access Points. Each port can deliver up to 15.4 W of PoE.
PoE+ inline power supports devices compliant with the IEEE 802.3at standard, by delivering up to 30 W
of PoE+ power per port to all switch ports.
See Table 1-17 on page 1-18 for the power supply modules required to support PoE and PoE+ on 24- and
48-port switches.
To access a PoE planning tool, use the Cisco Power Calculator available on Cisco.com:

Where to Go Next
You can use this application to calculate the power supply requirements for a specific PoE configuration.
Enter the number and types of powered devices that you plan to attach to the switch, and the calculator
shows the PoE or PoE+ power required and the system power consumption.
You must be a registered Cisco.com user to access the Cisco Power Calculator. If you do not have a user
ID or password, you can register:
http://tools.cisco.com/RPF/register/register.do
For more information about the required power-supply module and the PoE specifications, see the
“Power Supply Modules” section on page 1-17 and Appendix A, “Technical Specifications.”
Note
Many legacy powered devices, including older Cisco IP phones and access points that do not fully
support IEEE 802.3af, might not support PoE when connected to the switches by a crossover cable.
Caution
PoE faults are caused when noncompliant cabling or powered devices are connected to a PoE port. Use
only standard-compliant cabling to connect Cisco prestandard IP Phones, wireless access points, or
IEEE 802.3af-compliant devices to PoE ports. A cable or device that causes a PoE fault must be removed
from the network.
Warning
Voice over IP (VoIP) service and the emergency calling service do not function if power fails or is
disrupted. After power is restored, you might have to reset or reconfigure equipment to regain access
to VoIP and the emergency calling service. In the USA, this emergency number is 911. You need to be
aware of the emergency number in your country. Statement 361
Warning
Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if
interconnections are made using uninsulated exposed metal contacts, conductors, or terminals.
Avoid using such interconnection methods, unless the exposed metal parts are located within a
restricted access location and users and service people who are authorized within the restricted
access location are made aware of the hazard. A restricted access area can be accessed only through
the use of a special tool, lock and key or other means of security. Statement 1072
Where to Go Next
If the default configuration is satisfactory, the switch does not need further configuration. You can use
any of these management options to change the default configuration:
•
Start the device manager, which is in the switch memory, to manage individual and standalone
switches. This is an easy-to-use web interface that offers quick configuration and monitoring. You
can access the device manager from anywhere in your network through a web browser. For more
information, see the switch getting started guide and the device manager online help.
•
Start the Network Assistant application, which is described in the Getting Started with Cisco
Network Assistant guide. Through this GUI, you can configure and monitor a switch cluster or an
individual switch.

Power Supply Module Overview
The switch operates with either one or two active power supply modules or with power supplied by an
expandable power supply, XPS-2200. A Catalyst 3750-X switch that is part of a StackPower stack
operates with power supplied by other stack switches.
You can use two AC modules, two DC modules, one AC and one DC module, or one module and a blank
cover.
All power supply modules have internal fans. All switches ship with a blank cover in the second power
supply slot.
The XPS-2200 operates in two modes:
•
In StackPower mode, it supplies power to the switches in the power stack (only Catalyst 3750-X
switches with IP Base image).
•
In expandable power supply mode, it supplies power to a switch when the switch power supply is
removed or fails. When you install or replace a power supply module, the switch software polls the
device. After polling, the power supply module provides power to the switch, and the XPS-2200 is
available to power other devices.

Installation Guidelines
Table 1-16 lists the switches and the compatible power-supply modules. Observe these guidelines when
removing or installing a power supply or fan module:
•
Do not force the power supply or fan module into the slot. This can damage the pins on the switch
if they are not aligned with the module.
•
A power supply or fan module that is only partially connected to the switch can disrupt the system
operation.
•
Remove power from the power-supply module before removing or installing the module.
Catalyst 3750-X and 3560-X Switch Hardware Installation Guide
OL-19593-01

Chapter 3
Power Supply and Fan Module Installation
Installing an AC Power Supply
•
You can remove and replace the power supply when the switch is connected to an XPS-2200 without
interrupting normal switch operation. After a delay of about 3 seconds, the switch power supply
automatically provides power, and the XPS-2200 is available to power other devices.
Caution
Do not operate the switch with one power-supply module slot empty. For proper chassis cooling, both
module slots must be populated, with either a power supply or a blank module.
Warning
Blank faceplates and cover panels serve three important functions: they prevent exposure to
hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI)
that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not
operate the system unless all cards, faceplates, front covers, and rear covers are in place.

Diagnosing Problems
The switch LEDs provide troubleshooting information about the switch. They show POST failures,
port-connectivity problems, and overall switch performance. You can also get statistics from the device
manager, the CLI, or an SNMP workstation. See the software configuration guide, the switch command
reference guide on Cisco.com, or the documentation that came with your SNMP application for details.
Switch POST Results
As the switch powers on, it begins the power-on self-test (POST), a series of tests that runs automatically
to ensure that the switch functions properly. It might take several minutes for the switch to complete
POST.
When the switch begins POST, the Status LED turns green. The System LED blinks green, and the other
LEDs stay green.
When POST completes successfully, the System LED remains green. The XPS LED is green for some
time and then returns to its operating status. The other LEDs turn off and return to their operating status.
If the switch fails POST, the System and Ethernet management port LEDs turn amber.
Note
POST failures are usually fatal. Contact your Cisco technical support representative if your switch does
not pass POST.
Switch LEDs
Look at the port LEDs for information when troubleshooting the switch. See the “LEDs” section on
page 1-8 for descriptions of the LED colors and their meanings.

Troubleshooting
Diagnosing Problems
Switch Connections
Bad or Damaged Cable
Always examine the cable for marginal damage or failure. A cable might be just good enough to connect
at the physical layer, but it could corrupt packets as a result of subtle damage to the wiring or connectors.
You can identify this situation because the port has many packet errors or the port constantly flaps (loses
and regains link).
•
Exchange the copper or fiber-optic cable with a known good cable.
•
Look for broken or missing pins on cable connectors.
•
Rule out any bad patch panel connections or media convertors between the source and destination.
If possible, bypass the patch panel or eliminate media convertors (fiber-optic-to-copper).
•
Try the cable in another port to see if the problem follows the cable.
•
Catalyst 3750-X switch StackWise cable: remove and inspect the cable and StackWise port for bent
pins or damaged connectors. If the StackWise cable is bad, replace it with a known good cable.
Ethernet and Fiber Cables
Make sure that you have the correct cable:
•
For Ethernet, use Category 3 copper cable for 10 Mbps UTP connections. Use either Category 5,
Category 5e, or Category 6 UTP for 10/100 or 10/100/1000 Mbps connections.
•
Verify that you have the correct fiber-optic cable for the distance and port type. Make sure that the
connected device ports match and use the same type encoding, optical frequency, and fiber type. For
more information about cabling, see the “SFP and SFP+ Module Cable Specifications” section on
page B-5.
•
Determine if a copper crossover cable was used when a straight-through was required, or the reverse.
Enable auto-MDIX on the switch, or replace the cable. See Table 2-3 for recommended Ethernet
cables.
Link Status
Verify that both sides have link. A broken wire or a shut down port can cause one side to show link even
though the other side does not have link.
A port LED that is on does not guarantee that the cable is functional. It might have encountered physical
stress, causing it to function at a marginal level. If the port LED does not turn on:
•
Connect the cable from the switch to a known good device.
•
Make sure that both ends of the cable are connected to the correct ports.
•
Verify that both devices have power.
•
Verify that you are using the correct cable type. See Appendix B, “Connector and Cable
Specifications” for more information.
•
Look for loose connections. Sometimes a cable appears to be seated but is not. Disconnect the cable
and then reconnect it.

Troubleshooting
Diagnosing Problems
10/100/1000 Port Connections
A port appears to malfunction:
•
Verify the status of all ports. See Table 1-8 on page 1-10 for descriptions of the LEDs and their
meanings.
•
Use the show interfaces privileged EXEC command to see if the port is error-disabled, disabled, or
shut down. Re-enable the port if necessary.
•
Verify the cable type. See Appendix B, “Connector and Cable Specifications.”
PoE Port Connections
A powered device connected to a PoE port does not receive power:
Caution
Note
•
Verify the status of all ports. See Table 1-9 and Table 1-13 for descriptions of the LEDs and their
meanings.
•
Use the show interfaces privileged EXEC command to see if the port is error-disabled, disabled, or
shut down. Re-enable the port if necessary.
•
Verify that the power supply installed in the switch meets the power requirements of your connected
devices. See the “Power Supply Modules” section on page 1-17 for more information.
•
Verify the cable type. Many legacy powered devices, including older Cisco IP phones and access
points that do not fully support IEEE 802.3af might not support PoE when connected to the switch
by a crossover cable. Replace the crossover cable with a straight-through cable.
Noncompliant cabling or powered devices can cause a PoE port fault. Use only compliant cabling to
connect Cisco prestandard IP phones, wireless access points, or IEEE 802.3af-compliant devices.
The output of the PoE circuit has been evaluated as a limited power source (LPS) per IEC 60950.
SFP Modules
Use only Cisco network modules and SFP modules.
•
Inspect the network module and SFP module. Exchange the suspect module with a known good
module.
•
Verify that the module is supported on this platform. (The switch release notes on Cisco.com list the
SFP and SFP+ modules that the switch supports.)
•
Use the show interfaces privileged EXEC command to see if the port or module is error-disabled,
disabled, or shut down. Re-enable the port if needed.
•
Make sure that all fiber connections are clean and securely connected.
•
For CX1 module connections, make sure that cable routing does not violate the minimum allowed
cable bend radius. See the module documentation for specific cabling requirements.

Chapter 4
Troubleshooting
Diagnosing Problems
Note
When ordering or using CX1 cables, ensure that the version identifier is 2 or higher.
•
For long wave SFP+ modules, a mode conditioning patch might improve performance over
maximum link distances with MMF connections.
Interface Settings
Verify that the port or interface is not disabled or powered off. If a port or interface is manually shut
down on either side of the link, it does not come up until you re-enable the interface. Use the show
interfaces privileged EXEC command to see if the interface is error-disabled, disabled, or shut down on
either side of the connection. If needed, re-enable the interface.
Ping End Device
Ping from the directly connected switch first, and then work your way back port by port, interface by
interface, trunk by trunk, until you find the source of the connectivity issue. Make sure that each switch
can identify the end device MAC address in its Content-Addressable Memory (CAM) table.
Spanning Tree Loops
STP loops can cause serious performance issues that look like port or interface problems.
A unidirectional link can cause loops. It occurs when the traffic sent by the switch is received by the
neighbor, but the traffic from the neighbor is not received by the switch. A broken cable, other cabling
problems, or a port issue could cause this one-way communication.
You can enable UniDirectional Link Detection (UDLD) on the switch to help identify unidirectional link
problems. For information about enabling UDLD on the switch, see the “Understanding UDLD” section
in the software configuration guide on Cisco.com.
Switch Performance
Speed, Duplex, and Autonegotiation
Port statistics that show a large amount of alignment errors, frame check sequence (FCS), or
late-collisions errors, might mean a speed or duplex mismatch.
A common issue occurs when duplex and speed settings are mismatched between two switches, between
a switch and a router, or between the switch and a workstation or server. Mismatches can happen when
manually setting the speed and duplex or from autonegotiation issues between the two devices.
To maximize switch performance and to ensure a link, follow one of these guidelines when changing the
duplex or the speed settings:
•
Let both ports autonegotiate both speed and duplex.
•
Manually set the speed and duplex parameters for the interfaces on both ends of the connection.
•
If a remote device does not autonegotiate, use the same duplex settings on the two ports. The speed
parameter adjusts itself even if the connected port does not autonegotiate.

Chapter 4
Troubleshooting
Resetting the Switch to the Factory Default Settings
Autonegotiation and Network Interface Cards
Problems sometimes occur between the switch and third-party network interface cards (NICs). By
default, the switch ports and interfaces autonegotiate.Laptops or other devices are commonly set to
autonegotiate, yet sometimes issues occur.
To troubleshoot autonegotiation problems, try manually setting both sides of the connection. If this does
not solve the problem, there could be a problem with the firmware or software on the NIC. You can
resolve this by upgrading the NIC driver to the latest version.
Cabling Distance
If the port statistics show excessive FCS, late-collision, or alignment errors, verify that the cable distance
from the switch to the connected device meets the recommended guidelines. See the “Cable and Adapter
Specifications” section on page B-5.
Resetting the Switch to the Factory Default Settings
If you have configured a new switch with a wrong IP address, or if all of the switch LEDs start blinking
when you try to enter Express Setup mode, you can clear the IP address that is configured on the switch.
Note
Resetting the switch deletes the configuration and reboots the switch.
To reset the switch:
1.
Press and hold the Mode button (Figure 1-1 on page 1-3).
The switch LEDs begin blinking after about 2 seconds. If the LEDs above the mode button turn solid
green, you can release the Mode button and run Express Setup to configure the switch. If the LEDs
do not turn solid green, continue with the next step.
2.
Continue holding down the Mode button. The LEDs stop blinking after an additional 8 seconds, and
then the switch reboots.
The switch now behaves like an unconfigured switch. You can configure the switch by using Express
Setup as described in the switch getting started guide on Cisco.com.
You can also configure the switch by using the CLI setup procedure. See Appendix C, “Configuring the
Switch with the CLI-Based Setup Program.”

To replace a failed data stack member:
1.
The replacement switch must be a Catalyst 3750-X switch.
2.
Power down the failed switch. Remove AC or DC input power, and if the switch is part of a
StackPower stack, remove the StackPower cables.
3.
Make sure the replacement switch is powered off, and then connect it to the stack.
If you had manually set the member numbers for the switch stack, manually assign the member
number of the failed switch to the replacement switch. To manually assign the stack member
number, see the switch software configuration guide on Cisco.com.
4.
Make the same Gigabit Ethernet connections on the replacement switch that were on the failed
switch.
5.

1. Modal bandwidth applies only to multimode fiber.
2. A mode-field diameter/cladding diameter = 9 micrometers/125 micrometers.
3. A mode-conditioning patch cord is required. Using an ordinary patch cord with MMF or 1000BASE-LX/LH SFP modules and a short link distance can
cause transceiver saturation and an elevated bit error rate (BER). When using the LX/LH SFP module with 62.5-micron diameter MMF, you must also
install a mode-conditioning patch cord between the SFP module and the MMF cable on both the sending and receiving ends of the link. The
mode-conditioning patch cord is required for link distances greater than 984 feet (300 m).
4. 1000BASE-ZX SFP modules can send data up to 62 miles (100 km) by using dispersion-shifted SMF or low-attenuation SMF; the distance depends on
the fiber quality, the number of splices, and the connectors.

Configuring the Switch with the CLI-Based
Setup Program
This appendix provides a CLI-based setup procedure for a Catalyst 3750-X and 3560-X standalone
switch or a switch stack. To set up the switch by using Express Setup, see the Cisco 3750-X and 3560-X
Switch Getting Started Guide. Before connecting the switch to a power source, review the safety
warnings in Chapter 2, “Switch Installation.”
Accessing the CLI
Accessing the CLI Through Express Setup
You can access the CLI on an unconfigured switch by placing the switch in Express Setup mode and then
connecting a switch Ethernet port or the Ethernet management port to the Ethernet port of your PC or
workstation. To put the switch into Express Setup mode, follow the steps described in the getting started
guide for powering on the switch and using Express Setup.
When the switch is in Express Setup mode, open a Telnet session to the switch by entering the IP address
10.0.0.1. Enter the setup user EXEC command. Enter the information described in the “Entering the
Initial Configuration Information” section on page C-6.
After you have entered the configuration information for the switch, save it to flash memory by using
the write memory privileged EXEC command.
Note
While in Express Setup mode, the IP address 10.0.0.1 remains active on the switch until you enter the
write memory command. You lose the Telnet connection after entering the write memory command.
For more information about using the CLI, see the command reference for this release.
Accessing the CLI Through a Console Port
You can enter Cisco IOS commands and parameters through the CLI.
