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.
The bezel is optional for PowerEdge R815 systems. For more information, see the
Front Bezel (Optional) section in Installing System Components chapter of the
PowerEdge R815 Hardware Owner's Manual.

Hard Drive

The optional front bezel of the system contains a lock. A locked bezel secures the
system hard drives. See
3.13.4

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. A Trusted
Computing Module (TCM) version of the planar is available for use where TCM is the
standard, for example, in China.
3.13.5

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.
3.13.6

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.
PowerEdge R815 only supports up to five minutes of operation with the cover off.
3.13.7

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.

USB Key

An optional USB memory key installed inside your system can be used as a boot device,
security key, or mass storage device. The USB connector must be enabled by the
Internal USB Port option in the Integrated Devices screen of the System Setup
program.
