Note: Some troubleshooting steps in the following sections
require you to power-cycle the terminal. When power-cycling a
terminal that uses an AC/DC power cord, always disconnect the
AC power cord from the wall outlet, surge protector, or power
strip. When power-cycling a terminal that uses a DC/DC power
cord, always disconnect the DC input cable connector from the
power supply.
