Hello everyone. I work for a school system in Florida, and have a crew that maintains over 100 individual nortel systems at school sites. We are having budget issues, and political issues, that prevent us from upgrading some of these older systems. In order to keep things running, I have a question for everyone: What tips/tricks have you found to repair an ailing 6x16/8x24/0x32/bcm50/bcm450/expansion module to keep it running? Things like replacing the 5.5v 1 Farad memory capacitor on 8x24's to repair the memory loss during a power failure or the most common fail point of a bcm50 is the power supply, etc.... I have decent electronic repair knowledge, and have no problems getting into repairing some of these components to save some money and time. Note: Farming it out to a third party for repair is not an option, the higher-ups rejected that suggestion. Thanks!
