Table 11. DC PSU status indicator codes
Power indicator codes Condition
Green A valid power source is connected to the PSU and the PSU is operational.
Blinking amber Indicates a problem with the PSU.
Not illuminated Power is not connected to the PSU.
Blinking green When hot-plugging a PSU, the PSU indicator blinks green. This indicates that there is a PSU mismatch
with respect to eciency, 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. This
results in a PSU mismatch condition or failure to turn the system on.
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 conguration to a Low Output
conguration or vice versa, you must turn o 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.
LCD panel
The LCD panel provides system information, status, and error messages to indicate if the system is functioning correctly or requires
attention. The LCD panel can be used to congure or view the system’s iDRAC IP address. For more information about error messages, see
the Dell Event and Error Messages Reference Guide at Dell.com/openmanagemanuals > OpenManage software.
The LCD panel is available only on the optional LCD bezel. The optional LCD bezel is hot pluggable.
