Description
NOTE:
Ensure that both the PSUs are of the same capacity.
NOTE:
Mixing PSUs from previous generations of Dell servers can result in a
PSU mismatch condition or failure to turn the system on.
D
Flashing amber
Indicates a problem with 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.
E
Not lit
Power is not connected.
Non-redundant power supply unit indicator codes
Press the self-diagnostic button to perform a quick health check on the non-redundant power supply unit (PSU) of the system.

Condition
Not lit
Power is not connected or PSU is faulty.
Green
A valid power source is connected to the PSU and the PSU is operational.
Locating Service Tag of your system
Your system is identified by a unique Express Service Code and Service Tag number. The Express Service Code 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.
