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 145.
To resolve a sluggish, unresponsive, or unusually behaving device:
Reset the device by pressing the RESET button for less than five seconds (see Figure 47)
or by removing and restoring AC power.
