CAUTION:
AC PSUs support both 240 V and 120 V input voltages except for 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.
Locating the Service Tag of your system
You can identify your system using the unique Express Service Code and Service Tag. Pull out the information tag in front of the system to
view the Express Service Code and Service Tag. Alternatively, the information may be on a sticker on the chassis of the system. The mini
Enterprise Service Tag (EST) is found on the back of the system. This information is used by Dell to route support calls to the appropriate
personnel.
