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 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 XC XR2 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 configuration to a Low

Output configuration or vice versa, you must turn off 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 also be used to configure or view the system’s iDRAC IP address. For information about the event and error

messages generated by the system firmware and agents that monitor system components, see the Error Code Lookup page at

qrl.dell.com.

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 off.

• When the system turns off and there are no errors, LCD enters the standby mode after five 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.
