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.
Step 13
(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 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.
• 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.
Step 14
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 15
Disconnect the switch from the PC, and install the switch in your network. See the “Managing the Switch” section
on page 6 for information about configuring and managing the switch.
If you need to rerun Express Setup, see the “Resetting the Switch” section on page 15.
