Table 18. 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.
