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.

Dell EMC PowerEdge T440 system overview
Condition
A valid power source is connected to the PSU, and the PSU is operational.
Indicates a problem with the PSU.
Power is not connected to the PSU.
When the firmware of the PSU is being updated, the PSU handle blinks green.
CAUTION:
Do not disconnect the power cord, or unplug the PSU when updating
firmware. If firmware update is interrupted, the PSUs do not function.
When hot-plugging a PSU, the PSU handle blinks green five times at a rate of 4 Hz and powers off.
It indicates a PSU mismatch regarding efficiency, feature set, health status, or supported voltage.
CAUTION:
If two PSUs are installed, both the PSUs must have the same type of label;
for example, Extended Power Performance (EPP) label. Mixing PSUs from previous
generations of PowerEdge servers is not supported, even if the PSUs have the same
power rating. It results in a PSU mismatch condition or failure to power on the
system.
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 conversely, you must turn off the system.
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.
