SV8500 EMA card replacement

[phadobas]

When my vendor reviewed my phone system recently after it was "acting up", he saw that I have the very first version of the EMA card. He informed me that there have been a lot of revisions done to that card and I should get the latest one. I did.

Now how do I replace it? Per the OPS manual, I pull the old card out, and put the new one in (after ensuring the switch settings are the same).

The manual doesn't say anything about service interruptions, shutting down the system for this procedure or anything else... Is it really just taking the old EMA card out and putting the new one in???

It's a redundant SV8500, S8 release, with 3 physical PIM-s and an lot of IP phones.

Please, let me know if any of you have experience with replacing EMA card on a live system.

Follow the manual. I believe there is a busy out switch on the card. You should not have to shut down to replace it.

It's done. There is no busy-out switch on the card. Just pull out the old one, ensure the switches are set exactly the same way on the new one, and plug it back in.

The manual says that after the procedure, set the time again on the system.

I looked at my DT700 phones after the procedure, and they all showed the correct time. So I didn't bother setting the time.

That is, until I started getting the following complaints:
-On TDM digital phones (Dterm Series E), the time got stuck at the point when I replaced the cards and wouldn't change.
-All SMDR records were reporting the exact same time for all calls: the time when I replaced the card

I then double checked and the DT700 phones showed the correct time. So looks like somewhere in the system, there is some different clock?!?!?

Anyways, after ATIM, all was good.
