Configuring the iLO Virtual Serial Port in the UEFI System Utilities
The following procedure describes the settings you must configure before you can use the iLO Virtual
Serial Port. This procedure is required for both Windows and Linux systems.
Procedure
1.
Access the UEFI System Utilities.
a.
Optional: If you access the server remotely, start an iLO remote console session.
b.
Restart or power on the server.
c.
Press
F9
in the server POST screen.
The UEFI System Utilities start.
2.
Set the Virtual Serial Port COM port.
a.
Click
System Configuration
, then click
BIOS/Platform Configuration (RBSU)
.
b.
Click
System Options
, then click
Serial Port Options
.
c.
In the
Virtual Serial Port
menu, select the COM port you want to use.
3.
Set the BIOS serial console and EMS properties.
a.
At the top of the
Serial Port Options
page, click
BIOS Serial Console and EMS
.
b.
In the
BIOS Serial Console Port
menu, select the COM port you want to use.
c.
In the
BIOS Serial Console Baud Rate
menu, select
115200
.
NOTE:
The iLO Virtual Serial Port does not use a physical UART, so the
BIOS Serial Console
Baud Rate
value has no effect on the speed the iLO Virtual Serial Port uses to send and receive
data.
d.
For Windows users only: In the
EMS Console
menu, select the COM port that matches the
selected
Virtual Serial Port
COM port.
4.
To save the changes and exit, press
F12
.
5.
When prompted to confirm the request, click
Yes - Save Changes
.
The UEFI System Utilities notify you that a system reboot is required.
6.
Click
Reboot
.
Configuring Linux to use the iLO Virtual Serial Port
You can manage Linux servers remotely using console redirection. To configure Linux to use console
redirection, you must configure the Linux boot loader (GRUB). The boot-loader application loads from the
bootable device when the server system ROM finishes POST. Define the serial interface as the default
interface so that if no input arrives from the local keyboard within 10 seconds (the default timeout value),
the system will redirect output to the serial interface (iLO Virtual Serial Port).
