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.
 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 PoE specificiations, see “Appendix B: Technical Specifications”
on page 50.
To resolve a sluggish, unresponsive, or unusually behaving device:
Reset the device by pressing the RESET button for less than five seconds (see Figure 10
on page 37) or by removing and restoring AC power.
Pressing the RESET button for more than five seconds will erase all data and
settings.
