As a favor, I'm helping a customer get as much out of their Mitel as possible.I'd like to sell them a system I am trained on, but.....
They blew a 9109-110-002 (lightning)and I found a 9109-110-001 in a system being removed across town. It seems to work, but I'm trying (without much success) to find out what the difference is.
I don't want to do harm, just get them working again...

Any help?

PS A buddy is tryng to get a good price on the removed system.
