Network Cable Disconnected or DHCP Server Error

[GeorgeRufle]

I haven't used my ISY lately but with the holiday season coming up I thought that I would dust off some of last years lighting programs. When I sat down at my computer I noticed that the "MEM' and "ERROR" LEDs on the ISY-99 were blinking on for about 1 second at what appear to be random intervals. Anywhere form a minute to several minutes.

 

I have done and noticed the following with no change in the symptoms;

 

1-Changed the network cable between my ISY-99 and WRT54G with a known good cable.

 

2-I can open a WEB browser connection to the ISY and control various lights around the house with no problem.

 

3-I connected to the ISY using HyperTerm and the ISY serial port. That is where I see the message "Network Cable Disconnected or DHCP Server Error" being printed out. The message shows up and then the two LEDs blink.

 

4-The PLM/Info status says "E.DA.E4v72/Connected"

 

5-The about box shows ....

 

My Lighting : uuid:00:21:b9:00:00:94 - Isteon_UD99 v.2.7.6

Product : ISY 99i Pro (1040)

--Open Auto-DR (21010)

My URL : http://192.168.1.100:11080/

Internet Access : Disabled

 

Has anyone seen this or a similar problem and what can be done to eliminate the error messages?

Hi George,

 

Those error indicate one of the following:

1. ISY is not connected to the network ... in your case, this cannot be the issue since you can already connect to your ISY

2. For some reason your router is refusing to renew your DHCP lease ... if you can actually get to your system, then I would really not worry about this since ISY keeps asking for a lease renewal and will eventually get it

 

 

With kind regards,

Michel

Thanks for the response.

 

My setup has been on all day and as you stated the ISY eventually got whatever it needed because the errors have stopped.

 

I checked the router and its DHCP service is enabled with the beginning address set to 192.168.1.100 with 50 users possible and 1 day lease time. I just don't like errors if they can be avoided.

 

Thanks again
