1 About this Guide

This guide provides instructions on how to use Express Setup to initially configure your
Catalyst 3750G Integrated Wireless LAN Controller switch. It also covers switch management options, the configuration procedures for the controller, basic rack-mounting procedures, stacking, port and module connections, power connection procedures, and any troubleshooting help.

The Catalyst 3750G Integrated Wireless LAN Controller switch has an integrated Cisco wireless LAN controller that can support Cisco Lightweight Access Points. The switch also has two internal Gigabit Ethernet ports (ports 27 and 28) that connect the switch and the controller. The integrated wireless LAN controller centralizes and simplifies network management of a wireless LAN. It collapses large numbers of managed lightweight access points and client devices into a single unified system.

For additional installation and configuration information for wireless LAN controller switches, see the Catalyst 3750 documentation on Cisco.com. For more information on the controller, see the Cisco Wireless LAN Controller Configuration Guide, Release 4.0 or later on Cisco.com. For system requirements, important notes, limitations, open and resolved caveats, and last-minute documentation updates, see the release notes, also on Cisco.com.

When using the online publications, refer to the documents that match the Cisco IOS software version running on the switch. The software version is on the Cisco IOS label on the switch rear panel.

For translations of the warnings that appear in this publication, see the Regulatory Compliance and Safety Information for the Catalyst 3750 Switch that accompanies this guide.

Equipment that You Supply to Run Express Setup

You need to supply this equipment to run Express Setup:

PC

Ethernet (Category 5) straight-through cable (as shown)

3 Running Express Setup

When you first set up the switch, you should use Express Setup to enter the initial IP information. Doing this enables the switch to connect to local routers and the Internet. You can then access the switch through the IP address for further configuration.

To run Express Setup:

Step 1 

Verify that no devices are connected to the switch. During Express Setup, the switch acts as a DHCP server. If your PC has a static IP address, before you begin, change your PC settings to temporarily use DHCP.

Step 2 

Connect the AC power cord to the switch and to a grounded AC outlet. The power-on self-test (POST) begins. During POST, the LEDs blink while a series of tests verify that the switch functions properly.

Step 3 

Wait for the switch to complete POST. It might take several minutes for the switch to complete POST.

Step 4 

Verify that POST has completed by confirming that the SYST LED remains green. If the switch fails POST, the SYST LED turns amber.

POST errors are usually fatal. Call Cisco Systems immediately if your switch fails POST.

Step 5 

Press and hold the Mode button for 3 seconds. When all of the LEDs above the Mode button turn green, release the Mode button.

If the LEDs above the Mode button begin to blink after you press the button, release it. Blinking LEDs mean that the switch has already been configured and cannot go into Express Setup mode. For more information, see the "Resetting the Switch" section.

Step 6 

Verify that the switch is in Express Setup mode by confirming that all LEDs above the Mode button are green. (On some switch models, the RPS LED remains off.)

Step 7 

Connect a straight-through Category 5 Ethernet cable (not provided) to any 10/100/1000 Ethernet port on the switch front panel and to the Ethernet port on the PC.

Step 8 

Verify that the LEDs on both Ethernet ports are green.

Step 9 

Wait 30 seconds.

Step 10 

Launch a web browser on your PC. Enter the IP address 10.0.0.1 in the web browser, and press Enter.

Step 11 

The Express Setup page appears. If it does not appear, see the "In Case of Difficulty" section for help.

Step 12 

Enter this information in the Network Settings fields:

In the Management Interface (VLAN ID) field, the default is 1. Enter a new VLAN ID only if you want to change the management interface through which you manage the switch and to which you assign IP information. The VLAN ID range is 1 to 1001.

In the IP Address field, enter the IP address of the switch. In the IP Subnet Mask field, click the drop-down arrow, and select an IP Subnet Mask.

In the Default Gateway field, enter the IP address for the default gateway (router).

Enter your password in the Switch Password field. The password can be from 1 to 25 alphanumeric characters, can start with a number, is case sensitive, allows embedded spaces, but does not allow spaces at the beginning or end. In the Confirm Switch Password field, enter your password again.

Step 13 

In the Wireless Controller Settings area (see the Figure in Step 11), the stack number displays the stack-member number of the switch.

Enter this information:

In the Management Interface (VLAN ID) field, the default is 0. Enter a new VLAN ID only if you want to change the management interface through which you manage the controller and to which you assign IP information. If you entered a VLAN ID other than 1 in Step 12, then enter the same VLAN ID for the controller. The VLAN ID range is 0 to 1001.

In the IP Address field, enter the IP address of the controller.

In the IP Subnet Mask field, click the drop-down arrow, and select an IP Subnet Mask.

In the Default Gateway field, enter the IP address for the default gateway (router).


Note If you are connecting more than one wireless controller switch, multiple rows appear in the wireless controller settings area.



Step 14 

(Optional) You can enter the Optional Settings information now or enter it later by using the device manager interface:

In the Host Name field, enter a name for the switch. The host name is limited to 31 characters; embedded spaces are not allowed.

In the Telnet Access field, click Enable if you are going to use Telnet to manage the switch by using the command-line interface (CLI). If you enable Telnet access, you must enter a Telnet password.

In the Telnet Password field, enter a password. The Telnet password can be from 1 to 25 alphanumeric characters, is case sensitive, allows embedded spaces, but does not allow spaces at the beginning or end. In the Confirm Telnet Password field, re-enter the Telnet password.

In the SNMP field, click Enable to enable Simple Network Management Protocol (SNMP). Enable SNMP only if you plan to manage switches by using CiscoWorks 2000 or another SNMP-based network-management system.

If you enable SNMP, you must enter a community string in the SNMP Read Community field, the SNMP Write Community field, or both. SNMP community strings authenticate access to MIB objects. Embedded spaces are not allowed in SNMP community strings. When you set the SNMP read community, you can access SNMP information, but you cannot modify it. When you set the SNMP write community, you can both access and modify SNMP information.

In the System Contact field, enter the name of the person who is responsible for the switch. In the System Location field, enter the wiring closet, floor, or building where the switch is located.

Step 15 

Click Submit to save your settings, or click Cancel to clear your settings.

When you click Submit, the switch is configured and exits Express Setup mode. The PC displays a warning message and then tries to connect with the new switch IP address. If you configured the switch with an IP address that is in a different subnet from the PC, connectivity between the PC and the switch is lost.

Step 16 

Disconnect the switch from the PC, and install the switch in your network. See the "Managing the Switch" section for information about configuring and managing the switch.

If you need to rerun Express Setup, see the "Resetting the Switch" section.

Refreshing the PC IP Address

After you complete Express Setup, you should refresh the PC IP address:

For a dynamically assigned IP address, disconnect the PC from the switch, and reconnect it to the network. The network DHCP server assigns a new IP address to the PC.

For a statically assigned IP address, change it to the previously configured IP address.

4 Managing the Switch

After you complete Express Setup and install the switch in your network, use the device manager or other management options described in this section for further configuration.

Using the Device Manager

The simplest way to manage the switch is by using the device manager that is in the switch memory. 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.

Follow these steps:

1. Launch a web browser on your PC or workstation.

2. Enter the switch IP address in the web browser, and press Enter. The device manager page appears.

3. Use the device manager to perform basic switch configuration and monitoring. Refer to the device manager online help for more information.

4. For more advanced configuration, download and run the Cisco Network Assistant, which is described in the next section.

Downloading Cisco Network Assistant

Cisco Network Assistant is a software program that you download from Cisco.com and run on your PC. It offers advanced options for configuring and monitoring multiple devices, including switches, switch clusters, switch stacks, routers, and access points. Network Assistant is free—there is no charge to download, install, or use it.

Follow these steps:

1. Go to this Web address: http://www.cisco.com/go/NetworkAssistant.

You must be a registered Cisco.com user, but you need no other access privileges.

2. Find the Network Assistant installer.

3. Download the Network Assistant installer, and run it. (You can run it directly from the Web if your browser offers this choice.)

4. When you run the installer, follow the displayed instructions. In the final panel, click Finish to complete the Network Assistant installation.

Refer to the Network Assistant online help and the getting started guide for more information.

Command-Line Interface

You can enter Cisco IOS commands and parameters through the CLI. Access the CLI either by connecting your PC directly to the switch console port or through a Telnet session from a remote PC or workstation.

Follow these steps:

1. Connect the supplied RJ-45-to DB-9 adapter cable to the standard 9-pin serial port on the PC. Connect the other end of the cable to the switch console port.

2. Start a terminal-emulation program on the PC.

3. Configure the PC terminal emulation software for:

9600 baud

8 data bits

No parity

1 stop bit

No flow control

4. Use the CLI to enter commands to configure the switch. See the software configuration guide and the command reference for more information.

Other Management Options

You can use SNMP management applications such as CiscoWorks Small Network Management Solution (SNMS) and HP OpenView to configure and manage the switch. You also can manage it from an SNMP-compatible workstation that is running platforms such as HP OpenView or SunNet Manager.

The Cisco IE2100 Series Configuration Registrar is a network management device that works with embedded Cisco Networking Services (CNS) agents in the switch software. You can use IE2100 to automate initial configurations and configuration updates on the switch.

See the "Accessing Help Online" section for a list of supporting documentation.

5 Preparing the Wireless LAN Controller for Operation

Follow these major steps to prepare the integrated wireless LAN controller for operation.

Using the Configuration Wizard to Configure the Controller

Logging into the Controller

Verifying Interface Settings and Port Operation

Connecting Access Points

Using the Configuration Wizard to Configure the Controller

Follow these steps to use the Configuration Wizard to configure the controller for basic operation:

Step 1 

Get the initial configuration parameter settings for the controller from your wireless LAN planner.

Step 2 

Launch a web browser on your PC.

Step 3 

If you have not already done so, assign a static IP address to your PC from the same subnet as the switch; otherwise, the web browser cannot establish a connection with the switch.

Step 4 

Enter the management IP address of the switch (which you set in Step 12 of the Express Setup) in the web browser, and press Enter. The Catalyst 3750 Device Manager page appears.

Step 5 

Under Contents, click Controller Device Manager.

Step 6 

When prompted for a username and password, enter admin in each field. The first page of the Configuration Wizard appears.

Step 7 

In the System Name field, enter the system name, which is the name that you want to assign to the controller. You can enter up to 32 ASCII characters.

Step 8 

In the User Name and Password fields, enter the administrative username and password for this controller. You can enter up to 24 ASCII characters for each. The default administrative username and password are both admin.

Step 9 

Click Next. The Service Interface Configuration page appears.

Step 10 

If you want the controller service-port interface to get an IP address from a DHCP server, check the DHCP Protocol Enabled check box. If you do not want to use the service port or if you want to assign a static IP address to the service-port interface, leave the check box unchecked.

The service-port interface controls communications through the service port, which is reserved for out-of-band management of the controller and for system recovery and maintenance in the event of a network failure. Its IP address must be on a different subnet from the management and AP-manager interfaces. You can use this configuration to manage the controller directly or through a dedicated management network to ensure service access during network downtime.

Step 11 

If you did not check the DHCP Protocol Enabled check box in Step 10, leave the IP address and the netmask for the service-port interface as they are, or change them as necessary. If you do not want to use the service port, enter 0.0.0.0 for both the IP address and the netmask.

Step 12 

Click Next. The Management Interface Configuration page appears.

Step 13 

Enter the VLAN identifier zero (0) if the VLAN ID set on the switch management interface is 1. If you entered a VLAN ID other than 1 on the switch management interface (see Step 12 of the Running Express Setup section), enter the same VLAN ID for the controller. Enter the IP address, the netmask, and the gateway for the management interface.

The management interface is the default interface for in-band management of the controller and for connectivity to enterprise services such as authentication, authorization, and accounting (AAA) servers.

Step 14 

Enter the IP addresses of the primary and the optional secondary DHCP servers that supply IP addresses to clients, the controller management interface, and, optionally, the service-port interface.

Step 15 

Click Next. The Miscellaneous Configuration page appears.

Step 16 

From the LWAPP Transport Mode drop-down box, choose Layer 3. The controller operates only in Layer 3 mode.

Step 17 

(Optional) In the RF Mobility Domain Name field, enter the name of the mobility group/
RF group to which you want the controller to belong.

Although the name that you enter here is assigned to both the mobility group and the RF group, these groups are not identical. Both groups define clusters of controllers, but they have different purposes. All of the controllers in an RF group are usually also in the same mobility group and the reverse. However, a mobility group facilitates scalable, system-wide mobility and controller redundancy, while an RF group facilitates scalable, system-wide dynamic RF management.

Step 18 

In the Country Code field, enter the code for the country in which the controller will be used. See the table below the Country Code field for the list of available country codes.

Step 19 

Click Next. The AP Manager Interface Configuration page appears.

Step 20 

Enter the VLAN identifier, the IP address, the netmask, and the gateway for the controller AP-manager interface.

The AP-manager interface is used for Layer 3 communications between the controller and lightweight access points and must have a unique IP address. It is usually configured on the same VLAN or IP subnet as the management interface, but this is not a requirement.

Step 21 

Enter the IP addresses of the primary and the optional secondary DHCP servers that supply IP addresses to the controller AP-manager interface. If the AP-manager interface is on the same subnet as the management interface, the AP-manager interface uses the same DHCP server IP address as the management interface.

Step 22 

Click Next. The Virtual Interface Configuration page appears.

Step 23 

In the IP Address field, enter the IP address of the controller virtual interface to be used by all controller Layer 3 security and mobility managers. You should enter a fictitious, unassigned IP address, such as 1.1.1.1.

The virtual interface is used to support mobility management, DHCP relay, and embedded Layer 3 security such as guest web authentication and VPN termination. All controllers within a mobility group must be configured with the same virtual interface IP address.

Step 24 

In the DNS Host Name field, enter the DNS host name if your controller uses an externally generated web authentication ID certificate that includes a DNS hostname.

Step 25 

Click Next. The WLAN Policy Configuration page appears.

Step 26 

In the WLAN SSID field, enter the network name or service set identifier (SSID). This is the default SSID that the access points use when they join a controller.

Step 27 

Under General Policies, check the DHCP Address Assignment Required check box to make clients request an IP address from a DHCP server, or uncheck this check box to allow clients to assign their own IP addresses.

Step 28 

Leave the rest of the parameters on this page at their default values, or change them to meet your deployment needs. Refer to the online help for additional information on specific parameters.

Step 29 

Click Next. The RADIUS Server Configuration page appears.

Step 30 

To configure a RADIUS server now, enter the IP address, the shared secret, and the communication port of the RADIUS server, and click Apply. Otherwise, click Skip. The IEEE 802.11 Configuration page appears.

Step 31 

Check or uncheck the 802.11a, 802.11b, and 802.11g Network Status check boxes to enable or disable each of the IEEE 802.11a, IEEE 802.11b, and IEEE 802.11g lightweight access point networks.

Step 32 

Check or uncheck the Auto RF check box to enable or disable the controller radio resource management (RRM) auto-RF feature.

The auto-RF feature enables the controller to automatically form an RF group with other controllers. The group dynamically elects a leader to optimize RRM parameter settings, such as channel and send power assignments, for the group.

Step 33 

Click Next. The Configuration Wizard Completed page appears.

Step 34 

Click Save and Reboot.

Step 35 

When prompted, click OK to confirm the reboot. The controller saves your configuration and reboots. The reboot process can take several minutes, so you might need to wait before accessing your web browser again.

Logging into the Controller

Follow these steps to log into the controller from the switch.

Step 1 

Telnet to the switch by using the switch IP address.

Step 2 

At the switch system prompt, enter session 1 processor 1, and press Enter. The session number is linked to the controller. If there are two switches and you want to access controller number 2, you would enter session 2 processor 1.

Step 3 

When prompted, enter a valid username and password to log into the controller, and press Enter. The administrative username and password were assigned in the Configuration Wizard and are case sensitive.

Verifying Interface Settings and Port Operation

Follow these steps to verify that your interface configurations have been set properly and that the controller ports are operational.

Step 1 

Enter show interface summary, and press Enter. This display shows the controller interface configurations:

Interface Name									Port  Vlan Id   IP Address      Type     Ap Mgr
------------------------------ 			----  --------  --------------  -------  -----
ap-manager                        LAG   10        10.91.104.99    Static   Yes
management                        LAG   10        10.91.104.93    Static   No
service-port                      N/A   N/A       10.10.0.9       Static   No
virtual                           N/A   N/A       1.1.1.1         Static   No

Link aggregation (LAG) is always enabled for the integrated wireless LAN controller and cannot be disabled. LAG bundles all of the controller distribution system ports into a single IEEE 802.3ad port channel. See the Cisco Wireless LAN Controller Configuration Guide 4.0 or later for more information.

Step 2 

Enter show port summary, and press Enter. This display shows the status of the controller distribution system ports, which serve as the data path between the controller and the Cisco lightweight access points and to which the controller management and AP-manager interfaces are mapped.

			STP   Admin   Physical   Physical   Link   Link    Mcast
Pr  Type   Stat   Mode     Mode      Status   Status  Trap   Appliance   POE
-- ------- ---- ------- ---------- ---------- ------ ------- --------- -------
1  Normal  Forw Enable  Auto       1000 Full  Up     Enable  Enable     N/A
2  Normal  Forw Enable  Auto       1000 Full  Up     Enable  Enable     N/A

A link status of Up means that the controller ports are fully operational.

Connecting Access Points

After you have configured the controller, use Category-5, -5e, -6, or -7 Ethernet cables to connect Cisco lightweight access points to the network.

As soon as the controller is operational, it starts to scan for access points. When it detects one, it records the its MAC address in its database. The controller RRM feature then automatically configures the access point to start sending and allowing clients to associate.

For the integrated wireless LAN controller, access points can operate only in Layer 3 Lightweight Access Point Protocol (LWAPP) mode.

You have prepared the controller for basic operation. See the Cisco Wireless LAN Controller Configuration Guide, Release 4.0 or later, for information on configuring the controller to meet the specific needs of your wireless network.

6 Planning Switch Stacks

Before connecting the Catalyst 3750 switches in a stack, keep in mind these planning considerations:

The size of the switch—See the"Technical Specifications" appendix of the Catalyst 3750 Switch Hardware Installation Guide for the switch dimensions. Stacking together switches of the same size makes it easier to cable the switches.

Length of cable—Depending on the configuration of your switch stack, 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 require the 1-meter cable or 3-meter cable, you can order it from your Cisco supplier. For cable numbers, see the Catalyst 3750 Switch Hardware Installation Guide.


Note For concepts and procedures for managing switch stacks, refer to the switch software configuration guide.


Powering Considerations

Consider these guidelines before you power the switches in a stack:

The sequence in which the switches are initially 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 20 seconds, power on the remaining switches in the stack.

If you have no preference for which switch becomes the stack master, power on all the switches in the stack within a 20-second timeframe. These switches participate in the stack master election. Switches powered on after the 20-second timeframe do not participate in the election.

Power off a switch before you add it to or remove it from an existing switch stack.



Note Stack master elections occur over a 10-second timeframe on switches running releases earlier than Cisco IOS Release 12.2(20)SE3.

For more information on stack master elections, see the "Managing Switch Stacks" chapter in the switch software configuration guide.


Cabling Considerations

These illustrations show the recommended Catalyst 3750 switch stack configurations with redundant StackWise cabling connections for optimized stack bandwidth. For more configuration examples, see the Catalyst 3750 Switch Hardware Installation Guide on Cisco.com.

Vertical Stacking

In this example, the stack uses the 0.5-meter StackWise cable to make redundant connections.

In this example, the stacks use both 0.5- and 3-meter StackWise cables to make redundant connections.

Side-By-Side Stacking

In this example, eight switches are stacked side-by-side with redundant connections by using 0.5- and 3-meter StackWise cables.

In this example, nine switches are stacked side-by-side with redundant connections by using 0.5- and 3-meter StackWise cables.

7 Rack-Mounting

This section covers basic 19-inch rack-mounting and switch port connections. For additional cabling information, see the Catalyst 3750 Switch Hardware Installation Guide on Cisco.com.

Equipment That You Supply

You need to supply a number-2 Phillips screwdriver to rack-mount the switch.

Before You Begin

When determining where to install the switch, verify that these guidelines are met:

Airflow around the switch and through the vents is unrestricted.

Temperature around the switch does not exceed 113°F (45°C).

Humidity around the switch does not exceed 85 percent.

Altitude at the installation site is not greater than 10,000 feet.

Clearance to the switch front and rear panels meets these conditions:

Front-panel LEDs 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.

Access to the rear of the rack is sufficient for connecting StackWise cables to stacked switches.

Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting fixtures.

For 10/100/1000 ports, the cable length from a switch to an attached device cannot exceed 328 feet (100 meters).

For cable lengths for small form-factor pluggable (SFP) modules, see the documentation that shipped with the module.

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


Attaching the Brackets

Use four Phillips flat-head screws to attach the long side of the brackets to wireless controller LAN switches in one of three mounting positions.

Rack-Mount the Switch

Use the black Phillips machine screw to attach the cable guide to the left or right bracket. Use the four number-12 Phillips machine screws to attach the brackets to the rack.

Connect the StackWise Cables

Follow these steps to connect the StackWise cable to the StackWise ports:

Step 1 

Remove the dust covers from the StackWise cables and StackWise ports, and store them for future use.

Step 2 

Insert one end of the StackWise cable into the StackWise port on the back of the switch.

Step 3 

Use the window in the StackWise cable to align the connector correctly. Secure the screws tightly.

Step 4 

Insert the other end of the cable into the connector of the other switch, and secure the screws tightly.


Caution Removing and inserting the StackWise cable can shorten its useful life. Do not remove and insert the cable more often than is absolutely necessary.


Note Always use a Cisco-approved StackWise cable to connect the switches.


Connect to the Switch Ports

This section describes how to connect to the fixed switch ports and the SFP module ports.

Connect to 10/100/1000 Ports

Follow these steps:

Step 1 

When you connect to servers, workstations, IP phones, wireless access points, and routers, insert a straight-through, twisted four-pair, Category 5 cable in a switch 10/100/1000 port.

Use a crossover, twisted four-pair, Category 5 cable when you connect to other switches, hubs, or repeaters.

Step 2 

Insert the other cable end into an RJ-45 connector on the other device.

The fixed ports on the Catalyst 3750 Power over Ethernet (PoE) switches provide PoE support for IEEE 802.3af-compliant devices. They also provide Cisco pre-standard PoE support for Cisco IP Phones and Cisco Aironet Access Points.

Each of the 24 10/100/1000 switch ports can deliver up to 15.4 W of PoE. 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.

By default, a Catalyst 3750 switch PoE port automatically provides power when a valid powered device is connected to it. For information about configuring and monitoring PoE ports, see the switch software configuration guide. For information about troubleshooting PoE problems, see the Catalyst 3750 Switch Hardware Installation Guide on Cisco.com.


Note The automatic medium-dependent interface crossover (auto-MDIX) feature is enabled by default on switches running Cisco IOS Release 12.2(18)SE or later. When the auto-MDIX feature is enabled, the switch detects the required cable type for copper Ethernet connections and configures the interfaces accordingly. Therefore, you can use either a crossover or a straight-through cable for connections to a copper 10/100, 10/100/1000, or 1000BASE-T SFP module port on the switch, regardless of the type of device on the other end of the connection.


Install the SFP Modules and Connect to the Ports

Follow these steps:

Step 1 

Grasp the module on the sides, and insert it into the switch slot until you feel the connector snap into place.

Step 2 

Insert an appropriate cable into the module port. Insert the other cable end into the other device.

For a list of supported modules, see the release notes on Cisco.com. For detailed instructions on installing, removing, and connecting to SFP modules, see the documentation that came with the SFP module.


Caution Removing and inserting an SFP module can shorten its useful life. Do not remove and insert SFP modules more often than is absolutely necessary.

Verify Port Connectivity

After you connect to the switch port, the port LED turns amber while the switch establishes a link. This process takes about 30 seconds. Then the LED turns green when the switch and the target device have an established link. If the LED is off, the target device might not be turned on, there might be a cable problem, or there might be a problem with the adapter installed in the target device. See the "In Case of Difficulty" section for information about online assistance.

8 In Case of Difficulty

If you experience difficulty, help is available in this section and also on Cisco.com. This section includes Express Setup troubleshooting, how to reset the switch, how to access help online, and where to find more information.

Troubleshooting Express Setup

If Express Setup does not run, or if the Express Setup page does not appear in your browser:

Did you verify that POST successfully ran before starting Express Setup?

If not, make sure that only the SYST and STAT LEDs are green before pressing the Mode button to enter the Express Setup mode.

Did you press the Mode button while the switch was still running POST?

If yes, wait until POST completes. Power cycle the switch. Wait until POST completes. Confirm that the SYST and STAT LEDs are green. Press the Mode button to enter Express Setup mode.

Did you try to continue without confirming that the switch was in Express Setup mode?

Verify that all LEDs above the Mode button are green. (The RPS LED is off.) If necessary, press the Mode button to enter Express Setup mode.

Does your PC have a static IP address?

If yes, before connecting to the switch, change your PC settings to temporarily use DHCP.

Did you connect a crossover cable instead of a straight-through Ethernet cable between a switch port and the Ethernet port of the PC?

If yes, connect a straight-through cable to an Ethernet port on the switch and the PC. Wait 30 seconds before you enter 10.0.0.1 in the browser.

Did you connect the Ethernet cable to the console port instead of to a 10/100/1000 Ethernet port on the switch?

If yes, disconnect the cable from the console port. Then connect the cable to an Ethernet port on the switch and the PC. Wait 30 seconds before you enter 10.0.0.1 in the browser.

Did you wait 30 seconds after you connected the switch and the PC before you entered the IP address in your browser?

If not, wait 30 seconds, re-enter 10.0.0.1 in the browser, and press Enter.

Did you enter the wrong address in the browser, or is there an error message?

If yes, re-enter 10.0.0.1 in the browser, and press Enter.


Resetting the Switch

This section describes how to reset the switch by rerunning Express Setup. These are reasons why you might want to reset the switch:

You installed the switch in your network and cannot connect to it because you assigned the incorrect IP address.

You want to clear all configuration from the switch and assign a new IP address.

You are trying to enter Express Setup mode, and the switch LEDs start blinking when you press the Mode button (which means that the switch is already configured with IP information).


Caution Resetting the switch deletes the configuration and reboots the switch.

To reset the switch:

Press and hold the Mode button. The switch LEDs begin blinking after about 3 seconds. Continue holding down the Mode button. The LEDs stop blinking after 7 more seconds, and then the switch reboots.

The switch now behaves like an unconfigured switch. You can enter the switch IP information by using Express Setup as described in the "Running Express Setup" section.

Troubleshooting the Wireless Controller

You can troubleshoot the controller by using the show platform wireless-controller privileged EXEC command.

It displays information about the internal wireless controller in a Catalyst 3750G Integrated Wireless LAN Controller Switch. You can use it to determine the stack number of a switch or switches in the stack that contain the integrated wireless LAN controller. The command output also displays the MAC address and IP address of the controller.
