The remote serial console provides the console, and the GUI provides the iLO MP menu functionality. Output from the console is stored in nonvolatile memory in the console log, regardless of whether or not any users are connected to a console. The remote serial console option relies on the virtual serial port. Virtual Serial Port The iLO MP contains a virtual serial port that enables it to actually be the console hardware device for the OS. This port is a serial interface between the host system and the iLO MP. The iLO MP converts the serial data stream to be available remotely through the remote serial console. The virtual serial port must be correctly enabled and configured in the host. The virtual serial port function is a bidirectional data flow of the data stream appearing on the server's serial port. Using the remote console paradigm, a remote user can operate as if a physical serial connection is present on the server's serial port. With the virtual serial port feature of the iLO MP, an administrator can access a console application such as Windows EMS remotely over the network. The iLO MP contains the functional equivalent of the standard serial port (16550 UART) register set, and the iLO MP firmware provides a Java applet that connects to the server serial port. If the serial redirection feature is enabled on the host server, the iLO MP intercepts the data coming from the serial port, encrypts it, and sends it to the web browser applet. For Linux users, the iLO MP virtual serial port feature provides an important function for remote access to the Linux server. By configuring a Linux login process attached to the server's serial port, you can use the iLO MP virtual serial port feature to remotely login to the Linux operating system over the network.

The Power & Reset page (Figure 6-8) enables you to view and control the power state of the server. It also provides you with options to reset the system, the BMC, or iLO MP. 76 Using iLO

The remote serial console provides the console, and the GUI provides the iLO MP menu
functionality.
Output from the console is stored in nonvolatile memory in the console log, regardless of whether
or not any users are connected to a console.
The remote serial console option relies on the virtual serial port.
Virtual Serial Port
The iLO MP contains a virtual serial port that enables it to actually be the console hardware
device for the OS. This port is a serial interface between the host system and the iLO MP. The
iLO MP converts the serial data stream to be available remotely through the remote serial console.
The virtual serial port must be correctly enabled and configured in the host.
The virtual serial port function is a bidirectional data flow of the data stream appearing on the
server's serial port. Using the remote console paradigm, a remote user can operate as if a physical
serial connection is present on the server's serial port.
With the virtual serial port feature of the iLO MP, an administrator can access a console application
such as Windows EMS remotely over the network. The iLO MP contains the functional equivalent
of the standard serial port (16550 UART) register set, and the iLO MP firmware provides a Java
applet that connects to the server serial port. If the serial redirection feature is enabled on the
host server, the iLO MP intercepts the data coming from the serial port, encrypts it, and sends
it to the web browser applet.
For Linux users, the iLO MP virtual serial port feature provides an important function for remote
access to the Linux server. By configuring a Linux login process attached to the server’s serial
port, you can use the iLO MP virtual serial port feature to remotely login to the Linux operating
system over the network.

Virtual Devices
The Virtual Devices tab enables you to access the Power & Reset page.
The Power & Reset page (
Figure 6-8
) enables you to view and control the power state of the
server. It also provides you with options to reset the system, the BMC, or iLO MP.
