ISY-99i/ISY-26 INSTEON:Assign a Static IP Address

Assigning a Static IP Address For Your ISY

• If you have access to ISY Admin Console, simply go to Admin Console | Configuration tab | Network and assign static values. Otherwise:

1. Telnet to ISY Telnet To Your ISY
2. Login using your ISY credentials
3. Issue "CT" command (case sensitive - all UPPERCASE)
4. Follow the instructions on the screen to enter
   • IP Address (example 192.168.1.5)
   • Netmask (usually 255.255.255.0)
   • Gateway (usually the IP address of your router, example 192.168.1.1)
   • DNS (usually the IP address of your router, example 192.168.1.1)

Please note that all the commands in the shell are in UPPERCASE.

Many routers start DHCP addresses at a higher range such as 192.168.1.100 static addresses so these need to be avoided

To assign the ISY a dynamic IP (assigned by a DHCP server), set the IP address to 0.0.0.0.
