The LCD panel is a graphics display controlled by iDRAC6. Error codes can be sent to the display by
either iDRAC6 or BIOS.
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.
The control panel board is connected to the planar via a 60-wire ribbon cable and a separate 5-wire
cable for USB signals only. The LCD plugs into the control panel through a 20-pin ZIF connector and
flex cable.

The TPM is used to generate/store keys, protect/authenticate passwords, and create/store digital
certificates. TPM can also be used to enable the BitLocker™ hard drive encryption feature in Windows
Server 2008.
TPM is enabled through a BIOS option and uses HMAC-SHA1-160 for binding. A Trusted Computing
Module (TCM) version of the planar is available for use where TCM is the standard, for example, in
China.

Power Off Security
109B
The control panel is designed such that the power switch cannot be accidentally activated. The lock
on the bezel secures the switch behind the bezel. In addition, there is a setting in the CMOS setup
that disables the power button function.

Intrusion Alert
110B
A switch mounted on the left riser board is used to detect chassis intrusion. When the cover is
opened, the switch circuit closes to indicate intrusion to Embedded System Management (ESM). When
enabled, the software can provide notification to the customer that the cover has been opened. The
PowerEdge R810 only supports up to 5 minutes of operation with the cover off.
