Option Heading
This feature is designed to provide a visual indication of what Sleep state the system is in. Each Sleep
state has a unique blink pattern. Default is disabled.
NOTE: A normal shutdown goes to the S4 state for Windows 8 or later.
S0 (On) = solid white light.
S3 (Stand By) = 3 blinks at 1 Hz (50% duty cycle) followed by a pause of 2 seconds (white light), repeated
cycles of 3 blinks and a pause.
S4 (Hibernation) = 4 blinks at 1 Hz (50% duty cycle) followed by a pause of 2 seconds (white light),
repeated cycles of 4 blinks and a pause.
S5 (Soft O) = Light is o.
Electronic labels Displays system labels.
Remote Management
Options
Active Management (AMT) (Intel only) (enable/disable). Default is enabled.
Allows you to discover, repair, and protect networked computing devices.
USB Key Provisioning Support (enable/disable) Default is disabled.
USB Redirection Support (enable/disable). Default is enabled.
USB redirection allows USB devices plugged into a client computer to be transparently redirected to the
guest operating system.
Uncongure AMT on next boot (Do Not Apply/Apply). Default is Do Not Apply.
SOL Terminal Emulation Mode (ANSI / VT100). Default is ANSI.
SOL (serial-over-LAN) terminal emulation mode is only activated during remote AMT (Active Management
Technology) redirection operations. The emulation options allow administrators to select which mode
works best with their console.
Show Uncongure ME Conrmation Prompt (enable/disable). Default is enabled.
Verbose Boot Messages (enable/disable). Default is enabled.
Verbose boot shows additional logging information during startup, which is mainly for debugging if
something goes wrong during bootup.
Watchdog Timer (enable/disable). Default is enabled.
Allows you to set amount of time for a operating system and BIOS watchdog alert to be sent if the timers
are not deactivated. BIOS watchdog is deactivated by BIOS and would indicate that a halt occurred during
execution if the alert is sent to the management console. An operating system alert is deactivated by the
operating system image and would indicate that a hang occurred during its initialization.
● OS Watchdog Timer (min.) – (5/10/15/20/25). Default is 5 min.
● BIOS Watchdog Timer (min.) – (5/10/15/20/25). Default is 5 min.
CIRA Timeout (min.) (1/2/3/4/Never)
CIRA is Customer Initiated Remote Assistance, an Intel service to help users employing Active
Manag
ement Technology (AMT).
