If your iPECS Telephone System experiences a power failure, here's what to check: * First, make sure the fuse or breaker is working and that the AC power is reaching the outlet. * Next, inspect the PSU fuse and LD21/LD22 on the backplane; replace the PSU if they're out. * If the problem persists, ensure the MPB is installed and check for any short circuits by removing boards from the KSU one at a time. * Also, check the DC output status on the MB if LD4 LED is off on the MPB.
