3.13 Security

3.13.1 Cover Latch

A tooled entry latch is provided on the top of the unit to secure the top cover to the chassis. See the
Opening and Closing the System section in the Installing System Components chapter in the
PowerEdge R715 Hardware Owner's Manual on Support.Dell.com for more information.

3.13.2 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 on the LCD
is viewable even when the bezel is installed.
The bezel is optional for PowerEdge R715 systems. For more information, see the Front Bezel
(Optional) section in the Installing System Components chapter in the PowerEdge R715 Hardware
Owner's Manual on Support.Dell.com.

3.13.3 Hard Drive

The optional front bezel of the system contains a lock. A locked bezel secures the system hard
drives. For more information, see the Hard Drives section in the Installing System Components
chapter in the PowerEdge R715 Hardware Owner's Manual on Support.Dell.com.

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. R715 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.
