170 Power On Self Test (POST)
MX3 Reference Guide E-EQ-MX3RG-J-ARC
Power On Self Test (POST)
Each time the MX3 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 MX3 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, refer to Chapter 7,
“Troubleshooting”. If the unit still operates erratically, contact LXE Customer Support (refer to
“Getting Help” section in Chapter 1, “Introduction”). You may need to return the MX3 for
service.
