4. Enter or change the parameters as desired. Changes to a parameter 
take effect immediately on the stack.
The parameters in the IP Parameters window are described below:
IP address
This parameter specifies the IP address of the stack. You must 
specify an IP address if you intend to remotely manage the stack 
using a web browser, a Telnet utility, or an SNMP management 
program. If you leave this field blank, the stack will attempt to 
obtain its IP parameters from a Bootp or DHCP server on the 
network. 
Subnet mask
This parameter specifies the subnet mask for the stack. You must 
specify a subnet mask if you intend to manage the stack remotely 
using a web browser, a Telnet utility, or an SNMP management 
program. 
Gateway address
This parameter specifies the default router’s IP address. This 
address is required if you intend to remotely manage the stack 
from a management station that is separated from the stack by a 
router. 
Domain name server
This is the IP address of the Domain Name Service (DNS). This 
address is required if you are using this service.
Default domain name
This is the domain name to which the switch belongs. This is 
recommended if you are using DNS.
Manager addresses
You can enter up to four IP addresses of network management 
stations or servers that are to receive SNMP traps from the switch. 
These parameters are optional.
Download password
This password is required when downloading AT-S25 image files 
from one AT-8300 stack to another stack. The default password is 
ATS25, displayed as a series of asterisks. You can keep the default 
or change it. A stack can only accept software downloads from 
another stack of the same product series if their download 
passwords are the same. The software automatically searches for 
this password during downloads without requiring you to enter it.
