other should flash with network activity.

23.2 Troubleshooting Flowchart

This is a drop-thru flowchart so after you complete each line-item drop down to the next
item until you have resolution of your issues at which point you do not need to continue
further down the flow.
Step 1: Programming not acting as expected?
1. ❑ Check PLM is powered up
2. ❑ Check ISY is powered up
3. ❑ Check for locked up INSTEON devices
4. ❑ Check ISY error lights
a. Flashing "Error" LED = file system issue
b. Flashing "Error + Memory" LEDs = IP network issue
c. Steady On "Rx" LED = ISY-to-PLM communication issue
Step 2: Can you access the ISY main screen?
1. ❑ Check local network issues
a. ❑ Power down the ISY, local router, and internet modem
b. ❑ Power up the internet modem, wait until connected to web
c. ❑ Power up the local router, wait until startup routine is complete
d. ❑ Power up the ISY, wait until startup routine is complete
e. ❑ Login to your router, check for IP conflicts
2. ❑ Check remote access (if it's part of your current issue)
a. ❑ Check your dynamic forwarding is correct
b. ❑ If using UPnP, consider switching to manual port forwarding
c. ❑ If using a portal service (http://www.check-it.ca/), check/test that it's
working
3. ❑ Try different login methods
a. ❑ Network places ISY icon
b. ❑ Local ISY IP (ie. 192.168.1.105)
c. ❑ UDI web link (http://www.universal-devices.com/99i/)
d. ❑ Your personal ISY web address
4. ❑ Try different ISY shell login methods
a. ❑ Telnet to the ISY, run configure TCP/IP, check for network issues
b. ❑ Connect with a null modem cable, see 23.4.2
Using the Serial Port
i. ❑ Login with HyperTerminal, 115200, 8, none, 1, none
