Power and Startup

Symptom Problem Corrective Action

There are power issues. The SoundPoint IP 550/560

phone has no power.

Do one of the following:

• Verify that no lights appear on the

phone when it is powered up.

• Check if the phone is properly plugged

into a functional AC outlet.

• Make sure that the phone isn't

plugged into a plug controlled by a

light switch that is off.

• If the phone is plugged into a power

strip, try plugging it directly into a wall

outlet instead.

• Try the phone in another room where

the electricity is known to be working

on a particular outlet.

• If using PoE, the power supply voltage

may be too high or too low.
