The switches do not have a power switch. They are powered on when the
external AC/DC power adapter is connected to the switch and the adapter
power cord to a power source. The external AC/DC power adapter automati-
cally 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 switch, be sure the cord is adequately sized for the switch'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
switch. If the supplied power cord does not fit, contact HP networking
support.
Use only the AC/DC power adapter and power cord (if applicable), supplied
with the switch. Use of other adapters or power cords, including those that
came with other HP networking products, may result in damage to the
equipment.
