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.

You need this equipment to set up the switch:

•A PC with Windows 2000 or XP installed.

•A web browser (Internet Explorer 5.5, 6.0, Netscape 7.1 or later) with JavaScript enabled.

•A straight-through or crossover Category 5 Ethernet cable to connect your PC to the switch.

Disable any pop-up blockers or proxy settings in your browser software and any wireless client

running on your PC.

To run Express Setup:

Step 1 Make sure that nothing is connected to the

switch.

During Express Setup, the switch acts as a

DHCP server. If your PC has a static IP

address, change your PC settings before you

begin to temporarily use DHCP.

Step 2 Power the switch.

For AC-powered switches, connect the AC

power cord to the switch power supply and

to a grounded AC outlet.

For DC-powered switches, see the wiring

instructions in the hardware installation

guide on Cisco.com.

Step 3 When the switch powers on, it begins the power-on self-test (POST). During POST, the

LEDs blink while tests verify that the switch functions properly.

Wait for the switch to complete POST, which can take several minutes.

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. See the “In Case of Difficulty” section on

page 22 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.

Step 6 If the LEDs above the Mode button blink after you press the button, release it. Blinking

LEDs mean that the switch is already configured and cannot go into Express Setup mode.

For more information, see the “Resetting the Switch” section on page 23.

Step 7 Verify that the switch is in Express Setup mode. Make sure that all LEDs above the Mode

button are green. (On some switch models, the RPS LED remains off.)

Step 8 Connect a Category 5 Ethernet cable to any

10/100/1000 Ethernet port on the switch

front panel or to the Ethernet management

port on the rear panel. Connect the other end

of the cable to the Ethernet port on your PC.

Step 9 Verify that the LEDs on both Ethernet ports are green.

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 Basic Settings page appears. If it does not appear, see the “In Case of

Difficulty” section on page 22.

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. 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 (Optional) Enter this information in the Ethernet Management Port Settings fields:

•In the IP Address field, enter the IP address of the Ethernet management port. In the

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

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.

•Enter the date, time, and time zone information in the System Date, System Time, and

Time Zone fields. Click Enable to enable daylight saving time.

Step 15 (Optional) You can select the Advanced Settings tab on the Express Setup window and enter

the advanced settings now or enter them later by using the device manager interface.

Step 16 (Optional) Enter this information in the Advanced Setting fields:

•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 change it. When you set the SNMP write community, you

can both access and change SNMP information.

•In the System Contact and System Location fields, enter a contact name and the wiring

closet, floor, or building where the switch is located.

Step 17 (Optional) You can enable IPv6 on the switch in the Advanced Settings screen. In the Enable

IPv6 field, click Enable to enable IPv6 on the switch. Note: Enabling IPv6 restarts the switch

when you complete Express Setup.

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 the PC

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 a 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.

Step 18 To complete Express Setup, click Submit in the Network Settings or the Advanced Settings

screen to save your settings. 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. If you enabled IPv6, the switch restarts.

Step 19 Disconnect the switch from the PC, and install the switch in your production network. See

the “Managing the Switch” section on page 8 for information about configuring and

managing the switch.

If you need to rerun Express Setup, see the “Resetting the Switch” section on page 23.

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 by connecting

your PC directly to the switch console port or to the Ethernet management port.

Using the switch console port:

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 console port on the switch.

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,

and 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.

Using the switch Ethernet management port:

Follow these steps:

1. Connect a Category 5 Ethernet cable to the PC Ethernet port. Connect the other end of the cable

to the Ethernet management port on the switch rear panel.

2. Start a Telnet session on the PC.

3. Enter the switch IP address that you assigned by using Express Setup.

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.
