Hi There
Will a MGI16 card work in a 7200s cabinet I was reading some stuff that said only an OAS or the embedded MGI ports will work, I haven't got a 7200s system to test it on I tried it on a 7100 system and it worked ok

Thanks for any help

Yes, it will work just fine. Just have to put it in one of the bottom slots (3,4,5).

Unless the newer software supports it, then no.
Had a contractor try it a few years ago and it wouldn't work.
Was upgrading from os7100.

Cool thanks I'll leave the MGI16 in the box and get an OAS card for the system

I just recently had an MGI 16 work in a 7200 system.

A OS7200 (MCP or MP20) will work fine with a MGI16
A OS7200s (MP20S) won't work with MGI16

Sorry I didn't see the s attached to that.
