Resolving General Functional Issues
To resolve a blank screen or device that does not work at all:
Ensure the AC plug is plugged into an electrical outlet not controlled by a wall switch.
Verify that the AC power outlet has power. Try plugging in some other AC device. If nothing works, contact an
electrician or use another power outlet.
Verify that the DC plug is plugged into the power jack on the device.
The system devices are not immediately active when powered up and after a power interruption. Allow at least 30
seconds for the device to boot up.
If this is a Gateway or ATA, check the LED status. The POWER LED should be GREEN.
For Desksets connected to PoE, check whether any PoE switch ports have been configured for devices that require
less power. If so, configure your PoE switch to auto-detect device power requirements. For Deskset PoE specificiations,
see page 203.
To resolve a sluggish, unresponsive, or unusually behaving device:
Reset the device by pressing the RESET button for less than five seconds or by removing and restoring AC power.
Pressing the RESET button for more than five seconds will erase all data and settings.
