Figure 11. LCD Panel Configuration
Figure 12. LCD Panel (Detailed View)
The LCD panel is located on the front of the system chassis to provide user access to buttons, display, and
I/O interfaces. Features of the system control panel include the following:
ACPI-compliant power button with an integrated green power LED (controlled by iDRAC6)
128x20 pixel LCD screen
Two navigation buttons
One select button
One system ID button
Non-maskable Interrupt (NMI) button (recessed)
Ambient temperature sensor
The LCD panel is a graphics display controlled by iDRAC6.
Error codes can be sent to the display by either
iDRAC6 or BIOS.
The system's LCD panel provides system information and status messages to signify when the system is
operating correctly or when the system needs attention.
The R515 BIOS has the ability to enter a secure mode through Setup, which locks the Power and NMI
buttons.
When in this mode, the power button can still be used to turn on the system, but it cannot be used
to turn off power to the system.
For more information on the LCD panel, see the LCD Panel Features (Optional) section in the About Your
System chapter in the PowerEdge R515 Hardware Owner’s Manual on Support.Dell.com.
