Installation Notes
Follow these steps to configure your switch with Express Setup:
Step 1 Contact your system administrator and obtain the IP address, the IP subnet mask, and the default gateway
for your switch.
Step 2 Enter the IP address of the switch in the IP Address field.
Step 3 Click the drop-down arrow in the IP Subnet Mask field, and select an IP Subnet Mask.
Step 4 Enter the IP address for the default gateway in the Default Gateway field.
A gateway (router or dedicated network device) is a system that connects a network on one subnet to one
or more networks on a different subnet.
Note You must specify a default gateway if the management workstation and the switch are on
different IP segments.
Step 5 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 embedded spaces at the beginning or end.
Step 6 Enter your password again in the Confirm Switch Password field.
You do not enter a username for the switch. After the switch is configured with an IP address, you can
use CMS to configure a username.
Step 7 (Optional) Enter a host name for the switch in the Host Name field. The host name is limited to 31
characters; embedded spaces are not allowed.
Step 8 (Optional) Enter the name of your system contact in the System Contact field. This identifies the system
administrator for the switch or network.
Step 9 (Optional) Enter your system location in the System Location field. This identifies the physical location
of the switch.
Step 10 (Optional) Click Enable in the Telnet Access field if you are going to use Telnet to manage the switch
by using the CLI. If you enable Telnet access, you must enter a Telnet password:
a. Enter a password in the Telnet Password field. The Telnet password can be from 1 to 25
alphanumeric characters, is case sensitive, allows embedded spaces, but does not allow embedded
spaces at the beginning or end.
b. Enter the Telnet password again in the Confirm Telnet Password field.
Step 11 (Optional) Click Enable to configure Simple Network Management Protocol (SNMP). Enable SNMP
only if you plan to manage switches by using Cisco Works or another SNMP-based
network-management system.
If you enable SNMP, you must enter a community string in either 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. If you set the SNMP read
community, users can access MIB objects, but cannot modify them. If you set the SNMP write
community, users can access and modify MIB objects.
Step 12 Click Save to save your settings to the switch, or click Cancel to clear your settings.
After you save your settings, the switch exits Express Setup mode. Your switch is now configured with
the new IP address. You can install the switch in your production network.
