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.)

• 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.

• If you do not have access to the rear panel, you should cable the switches before you rack-mount

them.

• Tighten the captive screws on power-supply modules and fan modules 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.

Installing Devices in 10-Gigabit Ethernet Slots

Installing Devices in 10-Gigabit Ethernet Slots

These sections describe how to install and remove X2 transceiver 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 and Converter Modules

• 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.

Chapter 2 Switch Installation

• 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 upper module slot (slot 1). Position the module face down

to install in the lower module slot (slot 2). Slide the module into the opening until the back of the module
faceplate is flush with the switch faceplate.

Caution Do not insert or remove an X2 transceiver module with fiber-optic cables still attached. An X2 module

interface might change to error disabled when a module is inserted or removed with the fiber-optic cables
still connected. If the interface is error disabled, you can re-enable the interface by using the shutdown
and no shutdown interface configuration commands.

Removing an X2 Transceiver or Converter Module

Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.

Caution Do not insert or remove an X2 transceiver module with fiber-optic cables still attached. An X2 module

interface might change to error disabled when a module is inserted or removed with the fiber-optic cables
still connected. If the interface is error disabled, you can re-enable the interface by using the shutdown
and no shutdown interface configuration commands.

Step 2 For X2 transceiver modules, disconnect the cables from the module. For fiber-optic modules, install the

optical bore dust plugs.

Caution Do not remove the converter module with SFP modules or cables installed. Always remove any cables

and modules before removing the converter module from the slot.

Step 3 For converter modules, disconnect the cables from the SFP module. Remove the SFP modules from the

converter module.

Step 4 Carefully pull on the X2 module sleeve, or pinch the tabs on the converter module to disengage it from

the slot. Grasp the edges of the module, and carefully slide it out of the slot.

Chapter 2 Switch Installation

Step 5 Reinstall a replacement module or an EMC plug in the 10-Gigabit Ethernet slot.

Step 6 Place the module in an antistatic bag or other protective environment.

Installing SFP Modules

This section describes how to install and remove SFP modules in the switch and the Cisco TwinGig
Converter Module slots. To use SFP modules, you must have a converter module installed in a 10-Gigabit
Ethernet slot.

See the “SFP Modules” section on page 1-3 and the switch release notes on Cisco.com for the list of
supported SFP modules. Use only Cisco 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.

For more information about installing, removing, cabling, and troubleshooting SFP modules, see the
module documentation that shipped with your device. For module cable specifications, see

The autonegotiation feature is enabled by default. The switch ports configure themselves to operate at
the speed of an attached device. If the 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.

The automatic medium-dependent interface crossover (auto-MDIX) feature is enabled by default. The
switch detects the required cable type for copper Ethernet connections and configures the interface
accordingly. 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 connected device.

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.

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.

CHA P T ER

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 solid green.

When POST completes successfully, the System LED stays green. The other LEDs turn off and return
to their operating status. If the switch fails POST, the System LED is amber.

Note POST failures are usually fatal. Contact your Cisco technical support representative if your switch does

not pass POST.

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 1-3 for a description of the LED colors and their meanings.

OL18479-01

Catalyst 2350 Switch Hardware Installation Guide

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).

• Examine or replace 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 the

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.

• Remove and inspect the stack cable and stack port for bent pins or damaged connectors. If the cable

is bad, replace it with a known good cable.

Chapter 4 Troubleshooting

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 Mb/s UTP connections. Use either Category 5,

Category 5e, or Category 6 UTP for 10/100 or 10/100/1000 Mb/s 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 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
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 port 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 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.

Table 2-1 for

4-2

• Look for loose connections. Sometimes a cable appears to be seated, but is not. Disconnect the cable

and then reconnect it.

Catalyst 2350 Switch Hardware Installation Guide

OL18479-01

Chapter 4 Troubleshooting

SFP Module Issues

Use only Cisco 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 SFP module. Exchange the suspect module with known good module. Verify that the

• Use the show interfaces privileged EXEC command to see if the port or module is error-disabled,

• Make sure that all fiber connections are properly cleaned and securely connected.

Interface Settings

An obvious but sometimes overlooked cause of port connectivity failure is a disabled interface. Verify
that the interface is not disabled or powered off for some reason. If an 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 interface. Use
the show interfaces privileged EXEC command to see if the interface is error-disabled, disabled, or
shutdown on either side of the connection. If needed, re-enable the interface.

Diagnosing Problems

module is supported on this platform. (The switch release notes on Cisco.com list the SFP modules
that the switch supports.)

disabled, or shutdown. Re-enable the port if needed.

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.

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 unidirectional link
problems. For information about enabling UDLD on the switch, see the “Understanding UDLD” section
in the switch software configuration guide on Cisco.com.

Switch Performance

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 mean 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. Mismatches
can happen when manually setting the speed and duplex or from autonegotiation issues between the two
devices.

OL18479-01

Catalyst 2350 Switch Hardware Installation Guide

4-3

Clearing the Switch IP Address and Configuration

To maximize switch performance and to ensure a link, follow one of these guidelines when changing the
duplex or speed settings.

• Let both ports autonegotiate both speed and duplex.

• Manually set the speed and duplex parameters for the ports on both ends of the connection.

• If a remote device does not autonegotiate, set the same duplex settings on the two ports. The speed

parameter adjusts itself even if the connected port does not autonegotiate.

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 are set to autonegotiate. Devices like laptops or other devices are
commonly set to autonegotiate, 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. You can
resolve this by upgrading the NIC driver to the latest available version.

Cabling Distance

Chapter 4 Troubleshooting

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

Specifications” section on page B-4 for cabling guidelines.

Clearing 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 configured IP address. The switch
returns to the factory default settings.

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.

1. Press and hold the Mode button (Figure 1-1 on page 1-2).

2. 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 the next step.

3. 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.

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-12 Identifying a Crossover Cable

Configuring the Switch with the CLI-Based Setup Program

This appendix provides a CLI-based setup procedure for a Catalyst 2350 switch. Before connecting the
switch to a power source, review the safety warnings in

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.

APPENDIX

Chapter 2, “Switch Installation.”

C

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

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.

OL18479-01

“Entering the

Entering the Initial Configuration Information

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 (

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

Appendix C Configuring the Switch with the CLI-Based Setup Program

Figure 1-3) and to the PC or terminal port.

–

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

page C-2.

“Entering the Initial Configuration Information” section on

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 need this information from your network administrator before you complete the setup program:

• Switch IP address

• Subnet mask (IP netmask)

• Enable secret password

• Enable password

C-2

• Telnet password

Catalyst 2350 Switch Hardware Installation Guide

OL18479-01

Appendix C Configuring the Switch with the CLI-Based Setup Program

Completing the Setup Program

The initial setup dialog appears at the console when you first press Enter.

Step 1 Enter Ye s 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.

The host name is limited to 63 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

Entering the Initial Configuration Information

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, Cisco Network Assistant, or the
CiscoWorks LAN Management Solution application. To configure SNMP later, enter no.

Configure SNMP Network Management? [no]: no

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

OL18479-01

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

Catalyst 2350 Switch Hardware Installation Guide

Entering the Initial Configuration Information

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
enable secret 5 $1$Ulq8$DlA/OiaEbl90WcBPd9cOn1
enable password enable_password
line vty 0 15
password terminal-password
no snmp-server
!
no ip routing

!
interface Vlan1
no shutdown
ip address 10.4.120.106 255.0.0.0
!
interface GigabitEthernet1/0/1
!
interface GigabitEthernet1/0/2

interface GigabitEthernet1/0/3
!
...<output abbreviated>
!

Appendix C Configuring the Switch with the CLI-Based Setup Program

interface GigabitEthernet1/0/23
!
end

Step 9 These choices appear:

[0] Go to the IOS command prompt without saving this config.

[1] Return back to the setup without saving this config.

[2] Save this configuration to nvram and exit.

If you want to save the configuration and use it the next time the switch reboots, save it in nonvolatile
RAM (NVRAM) by selecting option 2.

Enter your selection [2]:2

Make your selection, and press Return.

After you complete the setup program, the switch can run the default configuration that you created. If
you want to change this configuration or want to perform other management tasks, use the CLI or another
management tool for further configuration.
