Installing the Switch
Installation Procedures
The switch automatically adjusts to any voltage between 100-127 or 200-240
volts and either 50 or 60 Hz. There are no voltage range settings required.
The Switch 2520G-8-PoE also does not have a power switch. It is 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
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 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 ProCurve Networking
support.
C a u t i o n Use only the AC/DC power adapter and power cord (if applicable), supplied
with the Switch 2520G-8-PoE. Use of other adapters or power cords, including
those that came with other ProCurve Networking products, may result in
damage to the equipment.
