I have a customer with an older Avaya which has 2 5-card carriers with a cable connecting the processors. All of the station modules are 206E ver 4.1. They recently had a nearby lightning strike and I replaced the processor in the expansion module. The processor on the main carrier has no slots for PCMCIA cards or any place to install batteries I think it is a ver 3.1. When I power down the unit I lose all programming, I am doing a #728 to save programming but it is still all lost. Is there a problem with this processor or am I missing something to save the programming?
