Note: For International use, you may need to change the AC line cord. You must
use a line cord set that has been approved for the receptacle type in your
country.
3. Check the front-panel LEDs as the device is powered on to be sure the PWR
LED is lit. If not, check that the power cable is correctly plugged in.
4. If you have purchased a Redundant Power Unit, connect it to the switch and to
an AC power source now, following the instructions included with the package.
