Option Description
NOTE: You can use only Serial Device 2 for the Serial Over LAN (SOL)
feature. To use console redirection by SOL, configure the same port
address for console redirection and the serial device.
NOTE: Every time the system boots, the BIOS syncs the serial MUX
setting saved in iDRAC. The serial MUX setting can independently be
changed in iDRAC. Loading the BIOS default settings from within the
BIOS setup utility may not always revert the serial MUX setting to the
default setting of Serial Device 1.
External Serial Connector Enables you to associate the External Serial Connector to Serial Device 1, Serial
Device 2, or the Remote Access Device by using this option. This option is set to
Serial Device 1 by default.
NOTE: Only Serial Device 2 can be used for Serial Over LAN (SOL). To
use console redirection by SOL, configure the same port address for
console redirection and the serial device.
NOTE: Every time the system boots, the BIOS syncs the serial MUX
setting saved in iDRAC. The serial MUX setting can independently be
changed in iDRAC. Loading the BIOS default settings from within the
BIOS setup utility may not always revert this setting to the default
setting of Serial Device 1.
Failsafe Baud Rate Specifies the failsafe baud rate for console redirection. The BIOS attempts to
determine the baud rate automatically. This failsafe baud rate is used only if the
attempt fails, and the value must not be changed. This option is set to 115200 by
default.
Remote Terminal Type Sets the remote console terminal type. This option is set to VT100/VT220 by
default.
Redirection After Boot Enables or disables the BIOS console redirection when the operating system is
loaded. This option is set to Enabled by default.

System Profile Settings details
Option Description
System Profile Sets the system profile. If you set the System Profile option to a mode other than Custom, the
BIOS automatically sets the rest of the options. You can only change the rest of the options if the
mode is set to Custom. This option is set to Performance Per Watt (OS) by default. Other
options include Performance and Custom.
NOTE: All the parameters on the system profile setting screen are available only when
the System Profile option is set to Custom.
CPU Power Management Sets the CPU power management. This option is set to OS DBPM by default. Other option includes
Maximum Performance.
Memory Frequency Sets the speed of the system memory. You can select Maximum Performance or a specific speed.
This option is set to Maximum Performance by default.
Turbo Boost Enables or disables the processor to operate in the turbo boost mode. This option is set to Enabled
by default.
C States Enables or disables the processor to operate in all available power states. C States allow the
processor to enter lower power states when idle. When set to Enabled (OS controlled) or when set
to Autonomous (if hardware controlled is supported), the processor can operate in all available
Power States to save power, but may increase memory latency and frequency jitter. This option is
set to
Enabled by default.
