Problems after replacing modem -- Solved!

[Slalom]

Yet another PLM took a dump so I ordered another and replaced it.

 

I followed the directions in the WIKI basically:

• powered down the ISY
• replaced the modem
• restored the modem

The new plm does not see updates from the devices but can query their status.

The devices operate normally and when queried the ISY programs control them as expected.

 

I have tried to restore devices and i have compared their link tables against what the ISY thinks

should be there all to no avail.

 

 

The wireless devices (remote Linc 2 and the Leak Sensors) seem to work correctly.

 

I have also found that if I remove a device and re-add it to the system it works correctly.

 

So the questions are:

What did I do wrong?

And (perhaps more importantly) how do I fix it without removing and reinstalling all of my devices.

 

Thanks for any help.

It seems that you missed a few steps in practice or in reporting.

 

power down the ISY <--done

replace the modem <--done

power up the modem first <--??

power up the ISY second <--??

restore the modem <--done

 

Order matters.

Pretty sure that I did the right order but perhaps I screwed up.

 

At this point I guess it is more important to figure out how to recover.  Can someone help?

First, retry the procedure, powering up in the correct order.

I have already done that.  More than once.

 

And on all subsequent tries the order was definitely proper.

Restore the ISY Backup taken just before PLM was replaced.  That takes the ISY back to the old PLM information.  Then power down ISY and PLM.  Power up PLM, wait 30 seconds and power up ISY.  Then Restore Modem (PLM).

Lee that was essentially what I had done.  I found out that when I ran the restore for the plm it did not restore everything to the devices.

 

Devices generally were missing some but not all of the plm records.

 

I was able to  resolve this by restoring all of the devices.

 

A little bit confused but back up and running.

 

Thanks to both Lee and Stu.
