4.11.5 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.
4.11.6 Intrusion Alert
A switch mounted on Riser 2 is used to detect chassis intrusion. When the cover is opened, the switch
circuit closes and indicates intrusion to the iDRAC6. When enabled, the software can provide
notification that the cover has been opened.
4.11.7 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 set up a system password.
4.12 USB Key
The port on the control panel is for an optional USB key and is located inside the chassis. 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-
swappable)
4.13 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.
4.14 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 backplane storage enclosure processor (SEP) and the power
