3.12.4 TPM

The TPM is used to generate/store keys, protect/authenticate passwords, and create/store digital certificates. TPM can also be used to store the 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. In China, the S-TPM (Socket TPM) is used.

3.12.5 Power Off Security

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

3.12.6 Intrusion Alert

A switch inside the chassis is used to detect chassis intrusion. When the system cover is opened, the switch circuit closes to indicate intrusion. When enabled, the software can provide notification to the customer that the cover has been opened.

3.12.7 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 to set up a system password.

3.13 USB Key

Dell does not offer USB keys for factory installation. The PowerEdge R515 supports two internal USB connectors which can be used for USB keys.

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 SP5100 chip.
