What to do if my Vertical Telephone system power fails?
- MMelissa WoodardJul 28, 2025
If your Vertical Telephone system experiences a power failure, it may be due to a power short circuit in one or more boards. Try exchanging any malfunctioning boards for ones known to be in good working order, and dust each board with a dry cloth. Also, check the PSU fuse and replace the PSU with an identical one if necessary.
