Hello! Will all of the MICS KSU's take the 6-Port Fiber Combo board? I've upgraded the unit to 6.1 software. Whenever I plug in the 6-Port Combo and unit will not boot up. The phone reads "Config Failure, Warm Reset."

Thanks,
Larry

Just make sure its in slot number 2 not number 1 ,it can only be in the number one slot if you have XC s/w.

Thanks Sam. I forgot that in Norstar Land you use Port 2 first for the fiber cards and Port 4 for the trunk cards.
