The E-MSM720 also does not have a power switch. It is powered on when the
external AC/DC power adapter is connected to the E-MSM720 and the adapter
power cord is connected to a power source. The external AC/DC power
adapter automatically adjusts to any voltage between 100-240 volts and either
50 or 60 Hz.
If your installation requires a different power cord than the one supplied with
the E-MSM720, be sure the cord is adequately sized for the E-MSM720's current
requirements. In addition, be sure to use a power cord displaying the mark of
the safety agency that defines the regulations for power cords in your country.
The mark is your assurance that the power cord can be used safely with the
E-MSM720. If the supplied power cord does not fit, contact HP Networking
support.
Use only the AC/DC power adapter and power cord supplied with the
E-MSM720. Use of other adapters or power cords, including those that came
with other HP Networking products, may result in damage to the equipment.
