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.)

10/100/1000 Ethernet Ports
The 10/100/1000 Ethernet ports use standard 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 more information about the 10/100/1000 Ethernet port connections and specifications, see the
“10/100/1000 Ethernet Port Connections” section on page 2-27 and Appendix B, “Connector and Cable
Specifications.”
PoE Ports
The 10/100/1000 PoE ports provide PoE support for devices compliant with IEEE 802.3af and also
provide Cisco pre-standard PoE support for Cisco IP Phones and Cisco Aironet Access Points.
Each port can deliver up to 15.4 W of PoE. With the 1150-W power-supply module, the
Catalyst 3750E-48PS and Catalyst 3560E-48PS switches can deliver 15.4 W on all 48 ports. With the
750-W power-supply module, the switches can deliver 15.4 W of PoE on any 24 of the 48 ports, or any
combination of the ports can deliver an average of 7.7 W of PoE at the same time, up to a maximum
switch power output of 370 W. On a per-port basis, you can control whether or not a PoE port
automatically provides power when an IP phone or an access point is connected.
Cisco intelligent power management capabilities include enhanced power negotiation, power
reservation, and per-port power policing. For information about configuring and monitoring PoE ports,
see the switch software configuration guide on Cisco.com at this location:
http://www.cisco.com/en/US/products/ps7077/products_configuration_guide_chapter09186a008077a3
5b.html
For more information about the required power-supply module, PoE port connections, and PoE
specifications, see the “Power-Supply Modules” section on page 1-15, the “PoE Port Connections”
section on page 2-27, and Appendix B, “Connector and Cable Specifications.”

Product Overview
Front Panel Description
10-Gigabit Ethernet Module Slots
The switch 10-Gigabit Ethernet module slots are used for uplink connection to other switches and
routers. The module slots operate in full duplex mode and use the hot-swappable Cisco X2 transceiver
modules and the Cisco TwinGig Converter Module. For the supported X2 transceiver modules, see the
switch release notes on Cisco.com at this location:
http://www.cisco.com/en/US/products/ps7077/prod_release_notes_list.html
For more information about the 10-Gigabit Ethernet module slots see the “Installing Devices in the
10-Gigabit Ethernet Slots” section on page 2-20. For cable specifications, see Appendix B, “Connector

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 displayed through 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.
On a Catalyst 3750-E switch stack, when you press the Mode button on any switch in the stack, all the
switches in the stack change to display the same selected mode. For example, if you press the mode
button on the stack master to display SPEED, all the other switches in the stack also display SPEED.

Power-Supply Modules
The 24- and 48-port switches are powered through an internal power-supply module. The “24- and
48-Port Switch Power-Supply Modules” section on page 1-15 and Table 1-11 describe the supported
power-supply modules for the switches.
The Catalyst 3560E-12D and 3560E-12SD switches are powered through two internal power-supply
modules. The “Catalyst 3560E-12D and 3560E-12SD Switch Power-Supply Modules” section on
page 1-16 and Table 1-13 describe the supported power-supply modules for the switch.
24- and 48-Port Switch Power-Supply Modules
The 24- and 48-port switches have one internal 265-W, 750-W, or 1150-W power-supply module
(Table 1-11). The 265-W and 750-W AC-power-supply modules are autoranging units that support input
voltages between 100 and 240 VAC. The 1150-W power-supply module is an autoranging unit that
supports input voltages between 115 and 240 VAC. The DC-power-supply module has dual input feeds
(A and B) and supports input voltages between 36 and 72 VDC.
The AC-power-supply modules have a power cord for connection to an AC power outlet. The 1150-W
and 750-W modules use a 16-AWG cord (only North America). All other modules use an 18-AWG cord.
The DC-power-supply module requires wiring to a DC-power source.
For switches connected to an RPS 2300, the RPS 2300 powers the switch when the power-supply is
removed or fails. When a new switch power supply is inserted, the switch software polls the device. The
switch power supply then automatically resumes providing power, and the RPS 2300 is available to
power other devices.

Catalyst 3560E-12D and 3560E-12SD Switch Power-Supply Modules
The Catalyst 3560E-12D and 3560E-12SD switches have two internal 300-W power-supply modules
(Table 1-13). The AC-power-supply modules are autoranging units that support input voltages between
85 and 265 VAC. The DC-power-supply modules have a single input feed and support input voltages
between –40.5 and –72 VDC. You can use two AC modules, two DC modules, or a mixed configuration
of one AC and one DC power-supply module.
The Catalyst 3560E-12D and 3560E-12SD switches can operate with only one active power-supply
module. However, two power supply modules must always be physically installed in the switch rear
panel when the switch is operating, even if one module is defective. This is required to maintain adequate
airflow in the chassis and prevent overheating.
Caution
Do not operate a Catalyst 3560E-12D or 3560E-12SD switch with one power-supply module removed
from the rear panel. For proper chassis cooling, two power-supply modules must be installed in the
switch rear panel.
The AC power-supply modules have a power cord for connection to an AC-power outlet. The DC
power-supply modules require wiring to a DC-power source. The AC-power supplies have an on/off
power switch. DC-power supplies do not have an on/off switch.

switch rear panel (part number C3K-BLWR-60CFM=).
The Catalyst 3560E-12D switch has four internal hot-swappable 12-V fan modules that insert in the
switch rear panel. The Catalyst 3560E-12SD switch has two internal hot-swappable 12-V fan modules
that insert in the switch rear panel. Each fan module (part number C3K-FAN-16CFM=) has a green LED
that shows that it is operating. The LED is off when there is a fan failure.
The Catalyst 3560E-12D or 3560E-12SD switch continues to operate when there is one failed fan, either
a power-supply fan or a chassis cooling fan. If one fan fails, the switch returns an error message. If a
second fan fails, either a power supply fan or a chassis cooling fan, the switch returns an error message,
writes a failure log to flash memory, and shuts down.
For more information about installing a fan module and the module specifications, see Chapter 3,
“Power Supply and Fan Module Installation,” and Appendix A, “Technical Specifications.”

Rear Panel Description
RPS Connector
The 24- and 48-port switches are supported by the Cisco RPS 2300 (model PWR-RPS2300=). The
Catalyst 3560E-12D and 3560E-12SD switches have two power supplies and are not supported by the
RPS-2300.
Warning
Attach only the following Cisco RPS model to the RPS receptacle: RPS 2300. Statement 370
The RPS 2300 is a redundant power system that can support six network switches and provide power to
one or two failed switches at a time. It automatically senses when the power supply of a connected switch
fails and provides power to the failed switch, preventing loss of network traffic.
The Cisco RPS 2300 has two output levels: –52 V and 12 V. The total maximum output power depends
on the installed power-supply modules.
The six ports on the RPS 2300 provide the power and management communication signals to the
Catalyst 3750-E and 3560-E switches (other switch models do not support this management
communication). The RPS 2300 communicates with each switch through the 22-pin cable. All connected
switches can communicate with the RPS 2300 simultaneously. You can configure these RPS 2300
features through the switch software:
•
Enable RPS active or standby mode for each connected switch
•
Configure switch priority for RPS support
•
List the connected switches and their power-supply module size
•
Report when a switch is powered by the RPS
•
Report the RPS power-supply module status
•
Read and monitor backup, failure, and exception history
For more information about the RPS 2300, including device support other than for the Catalyst 3750-E
and 3560-E switches, see the Cisco Redundant Power System 2300 Hardware Installation Guide on

Preparing for Installation
Installation Guidelines
Before installing the switch, verify that these guidelines are met:
•
Clearance to front and rear panels is such that
– Front-panel indicators can be easily read.
– Access to ports is sufficient for unrestricted cabling.
– AC power cord can reach from the AC power outlet to the connector on the switch rear panel.
– The X2-10GB-CX4 transceiver module minimum bend radius and connector length is met. See
the X2 transceiver module documentation for more information.
•
For switches that support the RPS 2300, confirm that you have access to the switch rear panel to
connect the RPS 2300. If you do not have access to the rear panel, you should cable the switches
before you rack-mount them.
•
For switches with the optional 1150-W power-supply module (C3K-PWR-1150WAC=), first
rack-mount the switch before installing the power-supply module.
•
For power-supply modules and fan modules, tighten the module captive screws before moving the
switch.
•
When connecting or disconnecting the power cord on a switch that is installed above or below a
1150-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 X2 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 required 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.
Box Contents
The box contents are described in the switch getting started guide. If any item is missing or damaged,
contact your Cisco representative or reseller for support.

Planning a Switch Stack (Catalyst 3750-E Switches)
If you plan to stack your switches, read these sections:
•
Switch Stacking Guidelines, page 2-6
•
Stack Cabling Configurations, page 2-7
•
Stack Bandwidth and Partitioning Examples, page 2-8
•
Power On Sequence for Switch Stacks, page 2-9
Switch Stacking Guidelines
For general concepts and procedures to manage switch stacks, see the switch software configuration
guide on Cisco.com. When adding a Catalyst 3750-E switch to an existing 3750 switch stack, review the
Catalyst 3750-E 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 1150-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 1-14. The “Stack Cabling Configurations”
section on page 2-7 provides examples of recommended configurations.
•
Access to the switch rear panel and to the rear of the rack if you are planning to stack the switches.
If you do not have access to the rear panel, make sure that you cable the switches before you
rack-mount them.
•
For switch stacks that are rack-mounted, review this recommended sequence of events:
– If you are using the RPS 2300, install the RPS first at the bottom of the stack. If needed, allow
one RU space between the RPS and the first switch above to provide room for cabling.
– Connect all the 22-pin RPS cables to the RPS 2300 as needed.
– Rack-mount the switches. If you have the optional 1150-W power-supply module, first
rack-mount the switch before installing the power-supply module.
– Connect the RPS cable to the first switch above the RPS 2300. Connect the stack cables to the
first switch above the RPS.
– Connect the RPS cable to the next switch above the RPS 2300. Connect the stack cables to the
next switch above the RPS.
– Repeat until all devices are connected.

Power On Sequence for Switch 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 a 1-minute timeframe. These switches participate in the stack master election.
Switches powered on after the 1-minute timeframe 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.

Installing Devices in the 10-Gigabit Ethernet Slots
Installing Devices in the 10-Gigabit Ethernet Slots
These sections describe how to install and remove X2 transceiver modules and the Cisco TwinGig
Converter Modules (also known as converter modules).
Use only Cisco X2 transceiver modules, converter modules, and SFP modules with the switch. Each
Cisco module has an internal serial EEPROM that is encoded with security information. This encoding
provides a way for Cisco to identify and validate that the module meets the requirements for the switch.
For more information about installing, removing, cabling, and troubleshooting X2 transceiver modules,
see the module documentation that shipped with your device. For module cable specifications, see
Appendix B, “Connector and Cable Specifications.”
Installing X2 Transceiver Modules and Converter Modules
When installing X2 transceiver modules and converter modules, observe these general precautions:
•
When you install or remove the converter module, the mode on the switch changes from 10-Gigabit
Ethernet to Gigabit Ethernet or the reverse. During this mode change, data traffic on the other switch
uplink ports (X2 transceiver or SFP module ports) might temporarily stop. When you install or
remove an X2 transceiver or SFP module, traffic delay does not occur.
•
Do not remove the EMC plug from the 10-Gigabit Ethernet slot until you are ready to install an X2
transceiver or a converter module. Either a module or an EMC plug must be installed in the slot at
all times.
•
Do not remove the dust plugs from the fiber-optic X2 transceiver 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 an X2 module can shorten its useful life. Do not remove and insert any X2
module more often than is absolutely necessary.
•
To prevent ESD damage, follow your normal board and component handling procedures when
connecting cables to the switch and other devices.
To install an X2 transceiver module or a converter module, follow these steps:
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
Step 4
Verify the correct orientation of your module before inserting it into the slot. Incorrect insertion can
damage the module.
For 24- and 48-port switches, position the module face up to install in the upper module slot (slot 1).
Position the module face down to install in the lower module slot (slot 2). See Figure 2-18 and
Figure 2-20. Slide the module into the opening until the back of the module faceplate is flush with the
switch faceplate.
For Catalyst 3560E-12D switches, position the module top facing right to install in a module slot. See
Figure 2-19 and Figure 2-21. Slide the module into the opening until the back of the module faceplate is
flush with the switch faceplate.

Connecting Devices to the Ethernet Ports
10/100/1000 Ethernet Port Connections
The 10/100/1000 Ethernet ports use standard 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 2-1 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 2-27.
The PoE ports provide PoE support for devices compliant with IEEE 802.3af and also provide Cisco
pre-standard PoE support for Cisco IP Phones and Cisco Aironet Access Points.
Each port can deliver up to 15.4 W of PoE. With the 1150-W power-supply module, the
Catalyst 3750E-48PS and Catalyst 3560E-48PS switches can deliver 15.4 W on all 48 ports. With the
750-W power-supply module, the switches can deliver 15.4 W of PoE on any 24 of the 48 ports, or any
combination of the ports can deliver an average of 7.7 W of PoE at the same time, up to a maximum
switch power output of 370 W. On a per-port basis, you can control whether or not a PoE port
automatically provides power when an IP phone or an access point is connected.

Note
On 48-port PoE switches, you must use the 1150-W power-supply module to provide full 15.4-W
capability across all 48 ports.
To access an advanced PoE planning tool, use the Cisco Power Calculator available on Cisco.com at this
URL:
http://tools.cisco.com/cpc/launch.jsp
You can use this application to calculate the power supply requirements for a specific PoE configuration.
The results show output current, output power, and system heat dissipation.
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 at this URL:
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 1-15, 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. Only
standard-compliant cabling can be used to connect Cisco pre-standard IP Phones and 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

and the installation guidelines:
•
Tools and Equipment, page 3-1
•
Installation Guidelines, page 3-1
Tools and Equipment
Obtain these necessary tools and equipment:
•
Ratcheting torque screwdriver with a number-2 Phillips head that exerts up to 15 pound-force inches
(lbf-in.) or 240 ounce-force inches (ozf-in.) of pressure. For 1150-W power-supply modules, the
screwdriver shaft length should be at least 6-inches long.
•
Power-supply power-cord retainer assembly in the switch accessory kit.
Installation Guidelines
Table 1-11 and Table 1-13 list 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.

Power Supply and Fan Module Installation
Installation Overview
Caution
•
Remove power from the power-supply module before removing or installing the module.
•
The 24- and 48-port switch supports hot swapping of the power supply when the switch is connected
to an RPS 2300. You can remove and replace the power supply without interrupting normal switch
operation. When you insert a new power supply in the switch, there is a 5-second delay while the
switch software polls the device. The switch power supply then automatically provides power, and
the RPS 2300 is available to power other devices.
•
The Catalyst 3560E-12D and 3560E-12SD switches support hot swapping of a power-supply
module when one of the two power supplies is active. You can remove and replace the power supply
without interrupting normal switch operation. When you insert a new power supply in the switch,
there is a 5-second delay while the switch software polls the device.
•
The Catalyst 3560E-12D and 3560E-12SD switches can operate with only one active power-supply
module. However, two power supply modules must always be physically installed in the switch rear
panel when the switch is operating, even if one module is defective. This is required to maintain
adequate airflow in the chassis and prevent overheating. When the switch is running on only one
power-supply module, redundant failover and load sharing is not available.
Do not operate the Catalyst 3560E-12D or 3560E-12SD switch with one power-supply module removed
from the rear panel. For proper chassis cooling, two power-supply modules must be installed in the
switch rear panel.
•
For the Catalyst 3560E-12D and 3560E-12SD switch power-supply modules, we recommend that
you connect the power-supply modules to separate AC or DC circuits for optimal power reliability.
•
The switch supports hot swapping of a fan module. When replacing a fan, you should complete the
replacement procedure within 2 minutes to avoid overheating the switch.
•
The Catalyst 3560E-12D and 3560E-12SD switch continues to operate when there is one failed fan,
either a power-supply fan or a chassis cooling fan. If one fan fails, the switch returns an error
message. If a second fan fails, either a power supply fan or a chassis cooling fan, the switch returns
an error message, writes a failure log to flash memory, and shuts down.
•
Make sure that all power supply and fan module captive screws are tightened before moving the
switch.
•
When replacing the 24- and 48-port switch 1150-W or 750-W power supply, verify that you are
using the correct power cord (CAB-16AWG-AC, only in North America).

•
Diagnosing Problems, page 4-1
•
How to Clear the Switch IP Address and Configuration, page 4-5
•
Finding the Switch Serial Number, page 4-6
•
How to Replace a Failed Stack Member, page 4-6
Diagnosing Problems
The LEDs on the front panel 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, from the CLI, or from 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.
Check 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 switch status LEDs turn green. The System LED blinks green, and
the other LEDs remain continuous green.
When POST completes successfully, the System LED remains green. The RPS LED remains 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 are amber.
Note
POST failures are usually fatal. Contact your Cisco technical support representative if your switch does
not pass POST.

Troubleshooting
Diagnosing Problems
Check Switch LEDs
If you have physical access to the switch, look at the port LEDs for troubleshooting information about
the switch. See the “LEDs” section on page 1-6 for a description of the LED colors and their meanings.
Check Switch Connections
Review this section when troubleshooting switch connection problems.
Bad or Damaged Cable
Always check 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). You should:
•
Check or swap 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 faulty media convertors (fiber-optic-to-copper).
•
Try the cable in another port or interface, if possible, to see if the problem follows the cable.
•
Catalyst 3750-E 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 type for the connection:
•
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.
•
For fiber-optic connectors, verify that you have the correct cable for the distance and port type.
Make sure that the connected device ports both match and use the same type encoding, optical
frequency, and fiber type. For more information about cabling, see the “10-Gigabit Ethernet X2
Transceiver Module Cable Specifications” section on page B-5 and the “SFP Module Cable
Specifications” section on page B-6.
•
For copper connections, determine if a crossover cable was used when a straight-through was
required, or the reverse. Enable auto-MDIX on the switch, or replace the cable. See the Table 2-1
for recommended Ethernet cables.
Link Status
Verify that both sides have link. A single broken wire or one shutdown port can cause one side to show
link, but the other side does not have link.
A link LED does not guarantee that the cable is fully functional. The cable might have encountered
physical stress that causes it to function at a marginal level. If the link light for the port does not come 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.
Catalyst 3750-E and Catalyst 3560-E Switch Hardware Installation Guide

OL-9774-03
Chapter 4
Troubleshooting
Diagnosing Problems
•
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.
•
Check for loose connections. Sometimes a cable appears to be seated, but is not. Disconnect the
cable and then reconnect it.
PoE Connections
When a powered device is connected to PoE port, but no power is received, you should:
•
Use the Mode button to show the PoE status for all ports. See Table 1-9 and Table 1-10 for a
description of the LEDs and their meanings.
•
Check the port status by using the show interfaces privileged EXEC command to check the port
error-disabled, disabled, or shutdown status. 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 1-15 for more information.
•
Check 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.
Caution
PoE faults are caused when noncompliant cabling or powered devices are connected to a PoE
port. Only standard-compliant cabling can be used to connect Cisco pre-standard IP phones
and wireless access points or IEEE 802.3af-compliant devices to PoE ports. (You must
remove a cable or device that causes a PoE fault from the network.)
Transceiver Issues
Use only Cisco X2 transceiver modules and SFP modules on the switch. Each Cisco module has an
internal serial EEPROM that is encoded with security information. This encoding provides a way for
Cisco to identify and validate that the module meets the requirements for the switch. Check these items:
•
Bad or wrong X2 transceiver, Cisco TwinGig Converter module, or SFP module. Exchange suspect
module with known good module. Verify that the module is supported on this platform. (The switch

•
Use the show interfaces privileged EXEC command to check the port or module error-disabled,
disabled, or shutdown status. Re-enable the port if needed.
•
Make sure that all fiber connections are properly cleaned and securely connected.

For LX4 modules, a mode conditioning patch is recommended for MMF applications.
Port and Interface Settings
An obvious but sometimes overlooked cause of port connectivity failure is a disabled port. Verify that
the port or interface is not disabled or powered down for some reason. If a port or interface is manually
shut down on one side of the link or the other side, the link does not come up until you re-enable the

Diagnosing Problems
port. Use the show interfaces privileged EXEC command to check the port or interface error-disabled,
disabled, or shutdown status on both sides of the connection. If needed, re-enable the port or the
interface.
Ping End Device
Check the end device by pinging 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 see the end device MAC address in its Content-Addressable Memory
(CAM) table.
Spanning Tree Loops
Spanning Tree Protocol (STP) loops can cause serious performance issues that look like port or interface
problems. In this situation, the switch bandwidth is used over and over again by the same frames, leaving
little room for legitimate traffic.
Loops can be caused by a unidirectional link. A unidirectional link occurs whenever the traffic sent by
the switch is received by its neighbor, but the traffic from the neighbor is not received by the switch. A
broken fiber-optic cable, other cabling, or a port issue could cause this one-way communication.
You can enable UniDirectional Link Detection (UDLD) on the switch to help identify difficult-to-find
unidirectional link problems. UDLD supports two modes of operation: normal (the default) and
aggressive. In normal mode, UDLD detects unidirectional links due to misconnected interfaces on
fiber-optic connections. In aggressive mode, UDLD also detects unidirectional links due to one-way
traffic on fiber-optic and twisted-pair links and due to misconnected interfaces on fiber-optic links. For
information about enabling UDLD on the switch, see the “Understanding UDLD” section in the software
configuration guide for this release.
Check Switch Performance
Review this section when troubleshooting switch performance problems.
Speed, Duplex, and Autonegotiation
If the port statistics show a large amount of alignment errors, frame check sequence (FCS), or
late-collisions errors, this might indicate a speed or duplex mismatch.
A common issue with speed and duplex is when the duplex settings are mismatched between two
switches, between a switch and a router, or between the switch and a workstation or server. This can
happen when manually setting the speed and duplex, or from autonegotiation issues between the two
devices. A mismatch occurs under these circumstances:
•
A manually set speed or duplex parameter is different from the manually set speed or duplex
parameter on the connected port.
•
A port is set to autonegotiate, and the connected port is set to full duplex with no autonegotiation.
To maximize switch performance and ensure a link, follow one of these guidelines when changing the
settings for duplex and speed:
•
Let both ports autonegotiate both speed and duplex.
•
Manually set the speed and duplex parameters for the ports on both ends of the connection.

Troubleshooting
How to Clear the Switch IP Address and Configuration
•
If a remote device does not autonegotiate, configure the duplex settings on the two ports to match.
The speed parameter can adjust itself even if the connected port does not autonegotiate.
Autonegotiation and NIC Cards
Problems sometimes occur between the switch and third-party network interface cards (NICs). By
default, the switch ports and interfaces are set to autonegotiate. It is common for devices like laptops or
other devices to be set to autonegotiate as well, yet sometimes autonegotation 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 your NIC card. You
can resolve this by upgrading the NIC card driver to the latest version available from the manufacture.
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 for cabling guidelines.
How to Clear the Switch IP Address and Configuration
If you have configured a new switch with a wrong IP address, or if all of the switch LEDs start blinking
when you are trying to enter Express Setup mode, you can clear the IP address that is configured on the
switch.
Note
This procedure clears the IP address and all configuration information stored on the switch. Do not
follow this procedure unless you want to completely reconfigure the switch.
Follow these steps to return your switch to the factory default settings:
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 switch is not configured, the LEDs
above the mode button turn green. You can omit this step and run Express Setup to configure the
switch.
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 that is included with the switch.
You can also configure the switch by using the CLI setup procedure described in the Configuring the
Switch with the CLI-Based Setup Program appendix.

How to Replace a Failed Stack Member
If you need to replace a failed stack member, you can hot swap or replace the switch by following this
procedure (only Catalyst 3750-E switches):
1.
Get a replacement switch that has the same model number as the failed switch.
2.
Power down the failed switch.
3.
Make sure the replacement switch is powered off, and then connect the replacement switch to the
stack.
If you had manually set the member numbers for any members in the stack, you need to manually
assign the replacement switch with the same member number as the failed switch. To manually
assign the member number, see the switch software configuration guide.
4.
Make the same Gigabit Ethernet connections on the replacement switch that were on the failed
switch.

1. A mode-conditioning patch cord is required. Using an ordinary patch cord with MMF, 1000BASE-LX/LH SFP modules, and
a short link distance can cause transceiver saturation, resulting in 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

Identifying a Crossover Cable
To identify a crossover cable, compare the two modular ends of the cable. Hold the cable ends
side-by-side, with the tab at the back. The wire connected to the pin on the outside of the left plug should
be the same color as the wire connected to the pin on the outside of the right plug. (See Figure B-13.)

Configuring the Switch with the CLI-Based
Setup Program
This appendix provides a CLI-based setup procedure for a Catalyst 3750-E and Catalyst 3560-E
standalone switch or a switch stack. Before connecting the switch to a power source, review the safety
warnings in Chapter 2, “Switch Installation.”
Accessing the CLI
For an unconfigured switch, you can access the CLI through Express Setup or through the console port.
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-2.
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 the Console Port
You can access the CLI on a configured or unconfigured switch by connecting the console port of the
switch to your PC or workstation and accessing the switch through a terminal emulation program.
Catalyst 3750-E and Catalyst 3560-E Switch Hardware Installation Guide
OL-9774-03
C-1
Appendix C
Configuring the Switch with the CLI-Based Setup Program
Entering the Initial Configuration Information
Note
For Catalyst 3750-E switches, if you have stacked your switches, connect to the 10/100 Ethernet
management port or console port of one of the switches in the stack. The initial configuration for the
entire stack can be performed on any switch in the stack.
Connecting to the Console Port
You can use the console port on the switch rear panel to perform the initial configuration as an
alternative to using Express Setup.
Follow these steps:
1.
Using the supplied RJ-45-to-DB-9 adapter cable, insert the RJ-45 connector into the console port on
the switch rear panel (Figure 1-7) and to the PC or terminal port.
1.
Start the terminal-emulation program on the PC or terminal. The terminal-emulation software,
frequently a PC application such as Hyperterminal or ProcommPlus, makes communication between
the switch and your PC or terminal possible.
2.
Start a terminal-emulation session.
3.
Configure the baud rate and character format of the PC or terminal to match these console port
default characteristics:
– 9600 baud
– 8 data bits
– 1 stop bit
– No parity
– None (flow control)
4.
Power on the switch as described in the switch getting started guide and in the “Installing an
AC-Power Supply” section on page 3-3.
5.
The PC or terminal displays the bootloader sequence. Press Enter to display the setup prompt.
Follow the steps described in the “Entering the Initial Configuration Information” section on
page C-2.
Entering the Initial Configuration Information
To set up the switch, you need to complete the setup program, which runs automatically after the switch
is powered on. You must assign an IP address and other configuration information necessary for the
switch to communicate with the local routers and the Internet. This information is also required if you
plan to use the device manager or Cisco Network Assistant to configure and manage the switch.
IP Settings
You will need this information from your network administrator before you complete the setup program:
•
Switch IP address
•
Subnet mask (IP netmask)

Appendix C
Configuring the Switch with the CLI-Based Setup Program
Entering the Initial Configuration Information
•
Default gateway (router)
•
Enable secret password
•
Enable password
•
Telnet password
Completing the Setup Program
If your switches are stacked and there are multiple console connections to individual switches in the
stack, the initial setup dialog appears at the console where you first press Enter.
Follow these steps to complete the setup program and to create an initial configuration for the switch:
Step 1
Enter Yes at the following two prompts.
Would you like to enter the initial configuration dialog? [yes/no]: yes
At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets '[]'.
Basic management setup configures only enough connectivity
for management of the system, extended setup will ask you
to configure each interface on the system.
Would you like to enter basic management setup? [yes/no]: yes
Step 2
Enter a host name for the switch, and press Return.
On a command switch, the host name is limited to 28 characters; on a member switch to 31 characters.
Do not use -n, where n is a number, as the last character in a host name for any switch.
Enter host name [Switch]: host_name
Step 3
Enter an enable secret password, and press Return.
The password can be from 1 to 25 alphanumeric characters, can start with a number, is case sensitive,
allows spaces, but ignores leading spaces. The secret password is encrypted, and the enable password is
in plain text.
Enter enable secret: secret_password
Step 4
Enter an enable password, and press Return.
Enter enable password: enable_password
Step 5
Enter a virtual terminal (Telnet) password, and press Return.
The password can be from 1 to 25 alphanumeric characters, is case sensitive, allows spaces, but ignores
leading spaces.
Enter virtual terminal password: terminal-password
Step 6
(Optional) Configure Simple Network Management Protocol (SNMP) by responding to the prompts.
You can also configure SNMP later through the CLI, the device manager, or the Network Assistant
application. To configure SNMP later, enter no.
Configure SNMP Network Management? [no]: no

Appendix C
Configuring the Switch with the CLI-Based Setup Program
Entering the Initial Configuration Information
Step 7
Enter the interface name (physical interface or VLAN name) of the interface that connects to the
management network, and press Return. For this release, always use vlan1 as that interface.
Enter interface name used to connect to the
management network from the above interface summary: vlan1
Step 8
Configure the interface by entering the switch IP address and subnet mask and pressing Return. The IP
address and subnet masks shown are examples.
Configuring interface vlan1:
Configure IP on this interface? [yes]: yes
IP address for this interface: 10.4.120.106
Subnet mask for this interface [255.0.0.0]: 255.0.0.0
Step 9
Enter Y to configure the switch as the cluster command switch. Enter N to configure it as a member
switch or as a standalone switch.
If you enter N, the switch appears as a candidate switch in the Network Assistant GUI. You can
configure the switch as a command switch later through the CLI, the device manager, or the Network
Assistant application. To configure it later, enter no.
Would you like to enable as a cluster command switch? [yes/no]: no
You have now completed the initial configuration of the switch, and the switch displays its initial
configuration. This is an example of output that appears:
The following configuration command script was created:
hostname switch1
