Troubleshoot DMP Setup, Operation, and Health
Check the LEDs
The DMP chassis contains a green LED and a red LED. After your DMP is attached to its AC power
source, you should see light from both LEDs through the DMP front grille. The LEDs tell you when your
DMP has power and when it has an IP address. To work as designed, it must have both.

Your DMP is connected to its power source and is receiving electrical power. However, it has not yet obtained an
IP address to use. Your DMP should obtain its IP address within 2 minutes. When the red LED persists:

•
For a wired network connection
— Are both ends of the Ethernet cable plugged in?
•
For a wireless network connection
— Is the wireless network active?
•
Does restarting your DMP resolve this problem?
•
Was any IP address in effect previously for your DMP? If so, can you ping that IP address? If you do not
remember what the address was, there are ways to obtain it. Turn On a presentation system that is connected
to your DMP and is configured or calibrated as necessary, and then try one of these methods.

When your DMP uses dynamic IP addresses that it receives from a DHCP server:
–
Has anything disrupted network traffic flow between your DMP and its DHCP server?
–
Is the DHCP server turned On and working correctly?
–
Does the DHCP server issue IP address leases that expire?

Off Your DMP is connected to its power source and is receiving electrical power. Furthermore, it has obtained and is
now using an IP address.
Off Off Your DMP does not have any electrical power and, thus, cannot obtain or use any IP address. Check that:
•
You are not experiencing a local or regional power outage.
•
All connectors are seated firmly.
•
Cords, plugs, adapters, and sockets do not show any signs of physical damage.
•
No one used software or sent commands to turn your DMP Off.
Blinking Infrared signal interference has affected your DMP. Investigate the source of this interference. Shield or move
equipment as necessary to restore normal operation.
