System Testing
Power On Self Test (POST)
Each time the MX1 is turned on (or is rebooted using <Ctrl> + <Alt> + <Del>), a series of
comprehensive hardware tests are performed. These tests are called the Power On Self Test, or
POST.
In the event that the system does not complete the POST, a beep code will sound. If this happens,
contact LXE Customer Support.
If the LXE MX1 display is operational and the unit appears to boot when you turn it on, yet
behaves in a manner that leads you to believe it is not working properly, contact LXE Customer
Support. You may need to return the MX1 for service.
POST Error Messages
The following table lists the POST error messages for the MX1. If problems persist, contact LXE
Customer Support.
