We have a Partner ACS R3 with Messaging module and another 3x8 card. All lights on the 3 modules are green and steady. However no phones get any power. I tried each port on each module. Any suggestions?
Shut the power off, and unseat all the modules. Reseat the center module, the processor. Reapply power. If it doesn't come up, that's the 1st thing to replace. If it is OK, Power off and add 1 module at a time. When you find one that causes the others to fail, pull it out and keep going, don't skip slots, you should be able to narrow it down.
