Mickamg - I try to take the SAFE way and what you described is the SAFE way.

Question is: You have TWO analog modules. Is the second one piggy backed off the first one and using just ONE fiber expansion port?
IF YES - THEN, which one is the BAD unit.

If they are NOT piggy-backed, then no issue.

IF they ARE piggy-backed then........
If the second unit is bad - no problem. Again I would take the safe way and disable the ASM module (that would disable both) then remove the bad unit.
and then re-enable it. And yes a backup would be good. I just don't know if it would care or care less when it suddenly does not see that second unit.

If the first unit is bad - as long as it is not dangerous, just leave it be and your second module will still have the same config.
IF you want to take out the first unit, then your second unit would now be your first and you would need to switch all the programming.
If you re-use the amphenol cable for the second unit the phones should still be connected, the programming would change with the new extensions.

Not being on site I can't say for sure, but what you say sounds good otherwise.



If CON is the opposite of PRO
