Locating Service Tag of your system

Your system is identified by a unique Express Service Code and Service Tag number. The Express Service Code is and Service Tag
are found on the front of the system by pulling out the information tag. Alternatively, the information may be on a sticker on the
chassis of the system. This information is used by Dell to route support calls to the appropriate personnel.

Condition
A valid power source is connected to the PSU and the PSU is operational.
When the PSU firmware is being updated, the PSU handle flashes green.
CAUTION: Do not disconnect the power cord or unplug the PSU when
updating firmware. If firmware update is interrupted, the PSUs will not
function. You must roll back the PSU firmware by using Dell Lifecycle
Controller. For more information, see Dell Lifecycle Controller User's Guide at
Dell.com/idracmanuals.
When hot-adding a PSU, the PSU handle flashes green five times at 4 Hz rate and
turns off. This indicates that there is a PSU mismatch with respect to efficiency,
feature set, health status, and supported voltage.
CAUTION: For AC PSUs, use only PSUs with the Extended Power
Performance (EPP) label on the back.
NOTE: Ensure that both the PSUs are of the same capacity.
NOTE: Mixing PSUs from previous generations of Dell PowerEdge servers can
result in a PSU mismatch condition or failure to turn the system on.
Indicates a problem in the PSU.
CAUTION: When correcting a PSU mismatch, replace only the PSU with the
flashing indicator. Swapping the other 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: AC PSUs support both 220 V and 110 V input voltages with the
exception of Titanium PSUs, which support only 220 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.
CAUTION: Combining AC and DC PSUs is not supported and triggers a
mismatch.
Power is not connected.
