TPM
The TPM is used to generate and store keys, protect and authenticate passwords, and create and store digital
certificates. The TPM can also be used to store Microsoft
®
BitLocker™ keys for hard drive encryption features in
Microsoft
®
Windows Server
®
2008. TPM is enabled through a BIOS option and uses HMAC-SHA1-160 for binding.
Power Off Security
The control panel is designed so 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
A switch mounted on Riser 2 is used to detect chassis intrusion. When the cover is opened, the switch circuit
closes and indicates intrusion to the iDRAC6. When enabled, the software can provide notification that the
cover has been opened.
Secure Mode
BIOS has the ability to enter a secure boot mode through Setup. This mode includes the option to lock out the
power and NMI switches on the control panel or set up a system password.
USB Key
The port on the control panel is for an optional USB key and is located inside the chassis. Some possible
applications of the USB key are listed as follows:
• User custom boot and pre-boot OS for ease of deployment or diskless environments
• USB license keys for software applications like eToken™ or Sentinel Hardware Keys
• Storage of custom logs or scratch pads for portable user defined information (not hot-
swappable)
Battery
A replaceable coin cell CR2032 3V battery is mounted on the planar to provide backup power for the Real-Time
Clock and CMOS RAM on the ICH9 chip.
Field Replaceable Units (FRU)
The planar contains a serial EEPROM to contain FRU information including Dell part number, part revision level,
and serial number. The backplane storage enclosure processor (SEP) and the power supply microcontrollers are
also used to store FRU data.
