Installation Manual

After Linux is fully booted, a login console can be redirected to the serial port.
• If configured, the /dev/ttyS0 and /dev/ttyS1 devices enable you to obtain serial TTY
sessions through the iLO Virtual Serial Port. To begin a shell session on a configured serial
port, add the following line to the /etc/inittab file to start the login process automatically
during system boot.
The following example initiates the login console on /dev/ttyS0:
S0:2345:respawn:/sbin/agetty 115200 ttyS0 vt100
The following example initiates the login console on dev/ttys1:
S1:2345:respawn:/sbin/agetty 115200 ttyS1 vt100
• Use SSH to connect to iLO, and then use the iLO CLP command start
/system1/oemhp_vsp1 to view a login session to the Linux operating system.
Windows EMS Console with iLO Virtual Serial Port
iLO enables you to use the Windows EMS Console over the network through a web browser.
EMS enables you to perform emergency management services when video, device drivers, or
other OS features prevent normal operation and normal corrective actions from being performed.
When using the Windows EMS Console with iLO:
• You must configure the Windows EMS console in the OS before you can use the iLO Virtual
Serial Port. For information about how to enable the EMS console, see your OS
documentation. If the EMS console is not enabled in the OS, iLO displays an error message
when you try to access the iLO Virtual Serial Port.
• The Windows EMS serial port must be enabled through the host system RBSU or the UEFI
System Utilities. The configuration options allow you to enable or disable the EMS port, and
select the COM port. iLO automatically detects whether the EMS port is enabled or disabled,
and detects the selection of the COM port.
• You can use the Windows EMS Console and the iLO Remote Console at the same time.
• To display the SAC> prompt, you might have to press Enter after connecting through the
iLO Virtual Serial Port.
