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 specied. 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, congure 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.
