The remote serial console option relies on the virtual serial port.
Virtual Serial Port
Integrity iLO 2 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 iLO 2. iLO 2 converts
the serial data stream to be available remotely through the remote serial console (a VT320 Java
applet). 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 iLO 2, an administrator can access a console application
such as Windows EMS remotely over the network. iLO 2 contains the functional equivalent of
the standard serial port (16550 UART) register set, and the iLO 2 firmware provides a Java applet
that connects to the server serial port. If the serial redirection feature is enabled on the host server,
iLO 2 intercepts the data coming from the serial port, encrypts it, and sends it to the web browser
applet.
For Linux users, the iLO 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 serial port,
you can use the iLO virtual serial port feature to remotely log in to the Linux operating system
over the network.
For more information on using the virtual serial port, see Integrated Lights-Out Virtual Serial Port
configuration and operation HOW TO on the HP website at:

Integrated Remote Console
The Integrated Remote Console (IRC) is a high-performance graphical console interface for
Windows clients running Internet Explorer. The IRC provides Virtual Keyboard, Video (monitor),
and Mouse (vKVM) capabilities with KVM over IP performance. The IRC data stream is encrypted,
enabling you to securely view and manage the server. The IRC does not use Java.
The IRC functionality enables a user with console access right and the Advanced Pack license to
perform the following:
• View the server graphics console and control the keyboard and mouse, as if you were
standing in front of the remote server
• Access the server from any location on the same network
• Perform maintenance activities.
• Diagnose server failures interactively
• Perform a controlled reset of the server, regardless of the state of the host operating system,
and remain connected to monitor the reboot process
• View a complete boot sequence following an automatic server recovery event
• View a log of remote console events
• Modify login passwords without administrator access right
• Remotely change the configuration parameters of the IRC
Because the iLO 2 IRC is hardware-based, it is available regardless of the state of the operating
system.
IRC Requirements and Usage
The IRC feature is only available if you have the iLO 2 Advanced Pack license. If iLO 2 is not
licensed to use the IRC, see the Licensing page under the Administration tab to activate the
Advance Pack license.
