To view the Serial Communication screen, power on the system, press F2, and click System Setup Main Menu > System
BIOS > Serial Communication.
Table 17. Serial Communication details
Option Description
Serial Communication Selects serial communication devices (Serial Device 1 and Serial Device 2) in
BIOS. BIOS console redirection can also be enabled, and the port address can
be specified. This option is set to Auto by default.
Serial Port Address Enables you to set the port address for serial devices. This option is set to
Serial Device1=COM2, Serial Device 2=COM1 by default.
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 that is 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
To view the System Profile Settings screen, power on the system, press F2, and click System Setup Main Menu > System
BIOS > System Profile Settings.
Table 18. 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.
