default IP address is 10.90.90.90. You can change the default Switch IP address to meet the 
specification of your networking address scheme. 
The Switch is also assigned a unique MAC address by the factory. This MAC address cannot be 
changed, and can be found on the initial boot console screen – shown below.

The Switch’s MAC address can also be found in the Web management program on the Switch 
Information (Basic Settings) window on the Configuration menu. 
The IP address for the Switch must be set before it can be managed with the Web-based manager. 
The Switch IP address can be automatically set using BOOTP or DHCP protocols, in which case 
the actual address assigned to the Switch must be known. 
Starting at the command line prompt, enter the commands config ipif System ipaddress 
xxx.xxx.xxx.xxx/yyy.yyy.yyy.yyy. Where the x’s represent the IP address to be assigned to the 
IP interface named System and the y’s represent the corresponding subnet mask. 
Alternatively, you can enter config ipif System ipaddress xxx.xxx.xxx.xxx/z. Where the x’s 
represent the IP address to be assigned to the IP interface named System and the z represents 
the corresponding number of subnets in CIDR notation. 
The IP interface named System on the Switch can be assigned an IP address and subnet mask 
which can then be used to connect a management station to the Switch’s Telnet or Web-based 
management agent. 
 
Command: config ipif System ipaddress 10.24.22.100/8 
 
Success.

In the above example, the Switch was assigned an IP address of 10.24.22.100 with a subnet mask 
of 255.0.0.0. The system message Success indicates that the command was executed 
successfully. The Switch can now be configured and managed via Telnet, SNMP MIB browser and 
the CLI or via the Web-based management agent using the above IP address to connect to the 
Switch.
