1100 series internal power supplies 1100 series internal power supplies telcodog (TechnicalUser) (OP) 14 May 18 17:44 Does anyone have a source for these things anymore. I have a pile of 1100 series phones that won't power up with POE or external power. I know we used to be able to buy them by the case. Thanks.

We have had some nasty experiences with the copy-pattern boards that where around 6-7 years ago -20-30% box failure rates, and loads more failures after 3-4 months of service. It got so bad that we stopped marketing them and instead just fix the old ones.
