remote console. The iLO 2 Remote Serial Console applet appears as a text-based console, but the

information is rendered using graphical video data. iLO 2 displays this information through the

remote console applet while in the server pre-operating system state, enabling a non-licensed iLO

2 to observe and interact with the server during POST activities.

For an iLO 2 blade (and an iLO blade running Linux in a graphical format), enter getty() on

the server's serial port, and then use iLO 2 Remote Serial Console or iLO Virtual Serial Port (CLP

command start /system1/oemhp_vsp1) to view a login session to the Linux operating system

through the serial port.

A non-licensed iLO 2 cannot use Remote Console access after the server completes POST and

begins to load the operating system. To use Remote Console and iLO Text Console after POST,

you must have an iLO 2 Advanced or iLO 2 Advanced for BladeSystem.

Text-based console after POST

The iLO 2 Text Console after POST feature is a text-based console accessible from Telnet or SSH

after POST. When using SSH, the data stream, including authentication credentials, is protected

by the encryption method supported by the SSH client and iLO 2. HP recommends using SSH to

connect to the iLO 2 Text Console.

iLO 2 also supports using Telnet to connect to the iLO 2 Text Console. However, the data stream

is not encrypted when using a normal Telnet connection. As part of the default security policy,

using Telnet is disabled. You must enable Telnet to allow access to the CLI, and iLO 2 Text Console.

For more information about the security of the communication methods used by iLO 2, see the

Integrated Lights-Out security technology brief on the HP website at http://h20000.www2.hp.com/

The presentation of colors, characters, and screen control depends upon the client you are using

and can be any standard Telnet (if enabled) or SSH client compatible with iLO 2. The iLO 2 Text

Console is enabled by default on iLO 2 firmware version 1.50 and later. Features and support

include:

• Displaying text mode screens that are 80 x 25 (standard color configurations) when the system

is on including:

— System boot process (POST)

— Standard Option ROMS

— Text boot-loaders (LILO or GRUB)

— Linux operating system in VGA 80x25 mode

— DOS

— Other text-based operating systems

Text mode screen support does not include graphics, other VGA text resolutions (132 x 48,

80 x 48), or other text resolutions implemented through a driver (implemented graphically).

• Remote Console hot keys

• International language keyboards (if the server and client system are configured similarly)

• Line-drawing characters when correct font and code-page are selected in the client application
