11.7.2 Testing the power connection
Check the PWR light on the modem: if it is turned on then the modem is powered. If it’s off,
then review the installation procedures.
If LED indicators are not accessible to the installer a personal computer can be used to verify
it’s functionality by running BlueVue Device Manager and attempt to connect to the modem.
