Page 20: Prepare The Installation Site
Before mounting the switch, verify it is working properly by plugging it into a power source and confirming that it passes self test. For the HP 1820 24- and 48-port switches, connect the power cord supplied with the switch to the power connector on the back of the switch, and then into a properly grounded electrical outlet. - Page 21 AC power outlet N o t e The HP 1820 24- and 48-port switches do not have a power switch. They are powered on when the power cord is connected to the switch and to a power source.
- Page 22 Installing the Switch Installation Procedure The HP 1820 8-port switches also 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 automatically adjusts to any voltage between 100-240 volts and either 50 or 60 Hz.
