3. Verify the Switch Passes Self Test

Before mounting the switch in its network location, you should first verify that
it is working properly by plugging it into a power source and verifying that it
passes its self test.

1.

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.

N o t e

The Switch 2650 does not have a power switch. It is powered on when the
power cord is connected to the switch and to a power source. For safety, the
power outlet should be located near the switch installation.

The switch automatically adjusts to any voltage between 100-240 volts and
either 50 or 60 Hz. There are no voltage range settings required.

If your installation requires a different power cord than the one supplied with
the switch, 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.
