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.

Condition
CAUTION: When correcting a PSU mismatch, replace only the PSU with the blinking
indicator. Swapping the PSU to make a matched pair can result in an error condition and
unexpected system shutdown. To change from a High Output configuration to a Low Output
configuration or vice versa, you must turn off the system.
CAUTION: If two PSUs are used, they must be of the same type and have the same
maximum output power.
CAUTION: Combining AC and DC PSUs is not supported and triggers a mismatch.
