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 congure or view the system’s iDRAC IP address. For information about the event and error
messages generated by the system rmware and agents that monitor system components, see the Error Code Lookup page, at
qrl.dell.com.
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 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 Getting help.
• The LCD backlight remains o if LCD messaging is turned o using the iDRAC utility, the LCD panel, or other tools.

Locating the Service Tag of your system
You can identify your system using the unique Express Service Code and Service Tag. Pull out the information tag in front of the system to
view the Express Service Code and Service Tag. Alternatively, the information may be on a sticker on the chassis of the system. The mini
Enterprise Service Tag (EST) is found on the back of the system. This information is used by Dell to route support calls to the appropriate
personnel.
