K. Control Panel/LCD

The system control 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:

•ACPI-compliant power button with an integrated green power LED (controlled by ESM)

•128x20 pixel LCD panel with controls

•Two navigation buttons

•One select button

•One system ID button

•Non-Maskable Interrupt (NMI) button (recessed)

•Ambient temperature sensor

•Two external USB 2.0 connectors

The LCD panel is a graphics display controlled by the iDRAC6, unlike the 9G panel which had its own CPLD. Error codes can be sent to the display by either iDRAC6 or BIOS.

The BIOS will have the ability to enter a "Secure Mode" through setup, which will lock the power and NMI buttons. When in this mode, pressing either button has no effect but does not mask other sources of NMI and power control.
