Observe the POST results. Approximately 30 seconds after the switch powers on, it begins the power-on self-test (POST), which can take up to 5 minutes to complete.

During POST, the SYSTEM LED blinks green. When POST is complete, the SYSTEM LED turns solid green. The ACTV LED is green if the switch is acting as the active switch.

Note Before going to the next step, wait until POST is complete.

Troubleshooting:

If the SYST LED does not turn solid green, or turns amber, the switch failed the POST. Contact your Cisco representative or reseller.

Press and hold the Mode button until all the LEDs next to the Mode button turn green.

You might need to hold the button for more than 3 seconds.

The switch is now in Express Setup mode.

Running Express Setup

Step 7

Step 8

Connect a Category 5 Ethernet cable to a port:

• Any 10/100/1000 or 10/100/1000 PoE+ or

10/100/1000 Cisco Universal Power Over Ethernet

ACTV

(Cisco UPOE) ports on the switch front panel.

• The RJ-45 management port on the switch rear panel.

Connect the other end of the cable to the Ethernet port on your PC or laptop.

Wait until the port LEDs on the switch and your PC or laptop or laptop are green or blinking green. Green LEDs indicate a successful connection.

Troubleshooting:

If the port LEDs do not turn green after about 30 seconds, make sure that:

• You connected the Ethernet cable to one of the

downlink switch ports (not to the console port).

• You are using an undamaged Category 5 or 6

Ethernet cable.

• The other device is turned on.

Start a browser session on the PC or laptop, and enter the IP address https://10.0.0.1. When prompted, enter the default password, cisco.

Step 10

Step 11

Enter this information in the Network Settings fields:

Note All entries must be in English letters.

• In the Management Interface (VLAN ID) field, the default is 1.

Note We recommend that you use the default VLAN value. During Express Setup, VLAN 1 is the only VLAN on

the switch. 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 switch IP address.

• In the Subnet Mask field, click the drop-down arrow, and select a 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 2 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.

Note You must change the default password, cisco.

(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 Subnet Mask field, click

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

(Optional) You can enter the Optional Settings information now or enter it later by using the Device Manager interface.

You can enter other administrative settings in the Optional Settings fields. For example, the optional administrative settings identify and synchronize the switch for enhanced management. NTP automatically synchronizes the switch clock with the network clock. You can manually set the system clock if the switch should have different settings.

(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.

• 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, reenter 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.

• (Optional) In the Enable IPv6 field, click Enable to enable IPv6 on the switch. The IPv6 field is enabled by

default.

Note Enabling IPv6 restarts the switch when you complete Express Setup.

Step 14

Step 15

Step 16

Click Submit to save your changes and to complete the initial setup.

After you click Submit:

• The switch is configured and exits Express Setup mode.

• The browser displays a warning message and tries to connect with the earlier switch IP address. Typically,

connectivity between the PC or laptop and the switch is lost because the configured switch IP address is in a different subnet from the IP address on the PC or laptop.

For more information about Express Setup fields, see the online help for the Express Setup window.

Disconnect the switch from the PC or laptop, and install the switch in your network. See the “Installing the Switch”

section on page 10.

If you changed the static IP address on your PC or laptop in Step 2, change it to the previously configured static IP address.

See the “Managing the Switch” section on page 7 for information about configuring and managing the switch.

To display Device Manager:

1. Start a web browser on your PC or laptop.

2. Enter the switch IP address, username, and password assigned in Step 9 in the browser, and press Enter.

The Device Manager page appears.

Troubleshooting:

If Device Manager does not appear:

• Confirm that the port LED for the switch port connected to your network is green.

• Confirm that the PC or laptop that you are using has network connectivity by connecting it to a well-known web

server in your network. If there is no network connection, troubleshoot the network settings on the PC or laptop.

• Make sure that the switch IP address in the browser is correct.

• If the switch IP address in the browser is correct, the switch interface LED is green, and the PC or laptop has

network connectivity, continue troubleshooting by reconnecting the PC or laptop to the switch. Configure a static IP address on the PC or laptop that is in the same subnet as the switch IP address.

When the LED on the switch port connected to the PC or laptop is green, reenter the IP address of the switch in a browser to display Device Manager. When Device Manager appears, you can continue with the configuration.

Managing the Switch

After completing Express Setup and installing the switch in your network, you can use these options for configuration:

• Device Manager

• Cisco Network Assistant

• Command-Line Interface

• Other Management Options
