System overview
LCD panel
The LCD panel provides system information, status, and error messages to indicate whether 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.
The LCD panel is available only on the optional front bezel. The optional front 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
l
descriptive text.
Note:

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
l
inactivity. Press any button on the LCD to turn it on.
If the LCD panel stops responding, remove the bezel and reinstall it.
