Upgrade MICS 3.0 to 7.1

[earjuice]

I thought I would check with you experts before I try anything. My client has an existing MICS cabinet with 3.0 software and needs to upgrade to a higher software version so as to get the hunt group feature. We might as well upgrade to 7.1 to get all the enhancements.

I know when I tried to do this upgrade on a CICS, the system could not recognize the software so I had to open the CICS up and short out the battery then restart the system with the new 7.1 cartridge installed. It took awhile but the system came to life with the 7.1 version. I don't know if you can do this type of action with a MICS and if someone should even attempt it.

I am being told that all I need to do is insert the 7.1 cartridge into the MICS and fire it up and then do the programming. I don't believe this as NORTEL advised using an upgrade tool to take the system to 4.0 then to 6.1 and finally 7.1.

My question: will a MICS with 3.0 software upgrade to 7.1 version simply by plugging in the new 7.1 cartridge and do you advise shorting out the internal battery?

You will need:
An NVRAM cartridge version 2, I don't believe (from memory) that 3.0 uses one.
The 4.1 upgrade tool and a 4.1 software.
The 6.1 upgrade tool and 6.1 software

It might be best to start from scratch as going from 3.0 to 7.1 can easily get corrupted.

Do a STARTUP on the system as it stands now.
When the screen says applying template, pull the power plug.
Insert your new NVRAM card and 7.1 and plug in the power.

Once the system comes up do a STARTUP again to clear all memory

I ditto Marv's post. Best to start with a clean slate when moving from R3.0 to R7.1. Just follow his instructions for upgrading using the STARTUP method.

I agree.
And Nortel was right.
As for shorting out the capacitor (not battery) it is the last resort.
Capacitors tale a toll on brownouts and surges and shorting etc which in turn yield a shorter life span.
Always use a 100ohm resistor if you must short out the cap and for 20 secs max.

Thanks to all that responded. You have confirmed my greatest fears so it would be a lot simpler to purchase a MICS with 7.1 instead of taking a chance.

Thanks again everyone!

No need to buy a new cabinet, just follow what Marv said and use the existing MICS.

Oh and just to add sometimes when you put in the 7.1 it could take up to 30 minutes or so to come up. so if it's not up in the normal 10 don't panic just give it time.
