lock on the side of the system.
TPM
The Trusted Platform Module (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.
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 the inside of the chassis, near the 5.25‖ drive bays, is
used to detect chassis intrusion. When the cover is opened, the switch
circuit closes to indicate intrusion.
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. For more information, see System and
Setup Password Features section in the About Your System chapter in the
PowerEdge T310 Hardware Owner’s Manual on Support.Dell.com/Manuals.
4.9 USB Key
The PowerEdge T310 has two ports inside the system on the planar for optional USB keys. 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-
pluggable)
4.10 Battery
A replaceable coin cell CR2032 3V battery is mounted on the planar to provide backup power for the
real-time clock (RTC) and CMOS RAM on the ICH chip.
There is also a battery holder for optional PERC cards which is located under the chassis cover.
4.11 Field Replaceable Units
The planar contains a 16 K x 8 serial EEPROM to store field replaceable units (FRU) information
including Dell part number, part revision level, and serial number. This part is also used as a system
event log (SEL) to be used by the baseboard management controller (BMC).
