Power supply unit indicator codes
AC power supply units (PSUs) have an illuminated translucent handle that serves as an indicator and DC PSUs have an LED that serves as
an indicator. The indicator shows whether power is present or a power fault has occurred.

AC PSU status indicator/handle
Table 10. AC 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 the rmware of the PSU is being updated, the PSU handle blinks green.
CAUTION: Do not disconnect the power cord or unplug the PSU when updating rmware. If
rmware update is interrupted, the PSUs do not function.
Blinking green and turns o When hot-plugging a PSU, the PSU handle blinks green ve times at a rate of 4 Hz and turns o. This
indicates a PSU mismatch with respect to eciency, 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 conguration to a low output conguration or
vice versa, you must turn o the system.

Power indicator codes Condition
CAUTION: AC PSUs support both 240 V and 120 V input voltages with the exception of Titanium
PSUs, which support only 240 V. When two identical PSUs receive dierent input voltages, they
can output dierent 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 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 eciency, 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 conguration to a Low Output
conguration 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 congure 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.
The statuses and conditions of the LCD panel are outlined here:
• The LCD backlight is white during normal operating conditions.
• When the system needs attention, the LCD backlight turns amber, and displays an error code followed by descriptive text.
NOTE: If the system is connected to a power source and an error is detected, the LCD turns amber regardless of whether
the system is turned on or o.
• When the system turns o and there are no errors, LCD enters the standby mode after ve minutes of inactivity. Press any button on
the LCD to turn it on.
• If the LCD panel stops responding, remove the bezel and reinstall it. If the problem persists, see the Getting help section.
• The LCD backlight remains o if LCD messaging is turned o using the iDRAC utility, the LCD panel, or other tools.
