i have a customer with a mics. that have maxed the basic cabinet out & require more stations. having confirmed with my supplier what i needed i got it. i got a 0X16 fiber station module, 1 fiber nam, and a 6 port fiber expansion card.

i turned off the system. plugged in the 6 port expansion into slot #1 & booted system up. display on 221 showed configuration error. so for fun i put it into slot 2 & same error. so i tried defaulting the system & then installing the 6 port. the system booted up but wouldn't let me into programming. kept saying: in use mega-sr.

i waited for 20 minutes. still same error. finally had to take it out & re-program whole system back the way it was.

why is this happening? i know i can have 2-6 port expansion cards in the system (per the manual).

my software version is: sp 30meF02 NAT
