Enhanced Preboot System Assessment

If you experience a problem with your system, run the system diagnostics before contacting Dell for technical assistance. The purpose of
running system diagnostics is to test your system hardware without requiring more equipment or risking data loss. If you are unable to fix
the problem yourself, service and support personnel can use the diagnostics results to help you solve the problem.

CAUTION: AC PSUs support both 240 V and 120 V input voltages with the exception of Titanium
PSUs, which support only 240 V. When two identical PSUs receive different input voltages, they
can output different wattages, and trigger a mismatch.
CAUTION: If two PSUs are used, they must be of the same type and have the same maximum
output power.
