II. Bezel
A metal bezel is mounted to the chassis front to provide the Dell ID. A lock on the bezel is used to
protect un-authorized access to system peripherals and the control panel. System status via the LCD is
viewable even when the bezel is installed.
III. Hard Drive
The optional front bezel of the system contains a lock. A locked bezel secures the system hard drives.
IV. TPM
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. There will be
different planar PWA part numbers to accommodate the different TPM solutions. The “Rest of World"
(ROW) version will have the TPM soldered onto the planar. The other version of the planar (post RTS
and primarily for use by China) will have a connector for a plug-in module.
V. Power Off Security
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.
VI. Intrusion Alert
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 ESM. When enabled, the software can provide
notification to the customer that the cover has been opened.
VII. Secure Mode
BIOS has the ability to enter a secure boot mode via Setup. This mode includes the option to lock out
the power and NMI switches on the Control Panel or set up a system password. See the 11th generation
of PowerEdge servers BIOS Specification for details
l. usb key
The port on the control panel is for an optional USB key and is located inside the chassis. Some of the
possible applications of the USB key are:
• 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 pad for portable user defined information (not hot-swappable)
m. 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.
n. 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 Advanced Management Enablement Adapter (AMEA) also
contains a FRU EEPROM. The backplane’s SEP and the power supplies’ microcontroller are also used to
store FRU data.
