Integrated Lights-Out 3 technology

Shared network port

Some servers offer a Shared Network Port (SNP) that allows network access to both iLO 3 and the server

through a single network port (see Figure 3), rather than dedicating a second port to iLO 3. With the

SNP, iLO 3 network traffic travels through a sideband connection on one of the NIC interfaces. Although

the iLO traffic shares a port with the server OS traffic, both iLO 3 and the server NIC have their own MAC

and IP address. iLO 3 using dual-MAC architecture provides an out-of-box shared network port; this

means that there is no need to run the configuration utility before you first log in to iLO 3.

Figure 3: These diagrams illustrate three possible port configurations for system management traffic.

Remote console and virtual media technologies

Through iLO 3 technologies such as remote console, virtual media, virtual power, and virtual serial port,

you can control iLO 3-managed servers efficiently. You can deploy new servers, install patches and hot-

fixes, perform routine maintenance tasks, or troubleshoot platform issues from any remote location.

Accessing the managed server console

iLO 3 lets you access the managed server using a text-based console, the Integrated Remote Console

(Microsoft® .NET framework based graphical console), or a Java-based Integrated Remote Console.

Text-based console (Virtual Serial Port)

You can use the iLO 3 Virtual Serial Port for text console access during POST and for text-based OSes like

Linux. iLO 3 contains hardware that can replace the physical serial port on the server's motherboard, and

the iLO 3 firmware provides a Java applet that connects to the server serial port. If you enable the serial

redirection feature on the server, iLO 3 intercepts the data coming from the serial port, encrypts it, and

sends it to an SSH client. Linux users must also set up a login shell to the serial port (TTYS0) and configure

the server to allow root access.

The redirection of text during the server boot process is available as an iLO 3 Standard feature on iLO 3

systems through the end of POST. Redirection of either text or graphics with iLO 3 after POST requires an
