from the serial port of the managed system. The serial port usually attaches to a shell that emulates an ANSI- or VT100/
VT220–terminal. The serial console is automatically redirected to the SSH.
Using SOL from PuTTY on Windows
NOTE: If required, you can change the default SSH time-out at iDRAC Settings > Services.
To start IPMI SOL from PuTTY on a Windows management station:
1. Run the following command to connect to iDRAC
putty.exe [-ssh] <login name>@<iDRAC-ip-address> <port number>
NOTE: The port number is optional. It is required only when the port number is reassigned.
2. Run the command console com2 or connect to start SOL and boot the managed system.
A SOL session from the management station to the managed system using the SSH protocol is opened. To access the iDRAC
command-line console, follow the ESC key sequence. Putty and SOL connection behavior:
● While accessing the managed system through putty during POST, if the Function keys and keypad option on putty is set
to:
○ VT100+ — F2 passes, but F12 cannot pass.
○ ESC[n~ — F12 passes, but F2 cannot pass.
● In Windows, if the Emergency Management System (EMS) console is opened immediately after a host reboot, the Special
Admin Console (SAC) terminal may get corrupted. Quit the SOL session, close the terminal, open another terminal, and
start the SOL session using the same command.
NOTE:
Due to windows OS settings, SOL session connected through ssh and IPMI tool may go to blank screen after
booting. Disconnect and Re-connect the SOL Session again to get back SAC prompt.
Using SOL from OpenSSH on Linux
To start SOL from OpenSSH on a Linux management station:
NOTE: If required, you can change the default SSH session time-out at iDRAC Settings > Services.
1. Start a shell.
2. Connect to iDRAC using the following command: ssh <iDRAC-ip-address> -l <login name>
3. Enter one of the following commands at the command prompt to start SOL:
● connect
● console com2
This connects iDRAC to the managed system’s SOL port. Once a SOL session is established, iDRAC command line console
is not available. Follow the escape sequence correctly to open the iDRAC command line console. The escape sequence is
also printed on the screen as soon as a SOL session is connected. When the managed system is off, it takes sometime to
establish the SOL session.
NOTE: You can use console com1 or console com2 to start SOL. Reboot the server to establish the connection.
The console -h com2 command displays the contents of the serial history buffer before waiting for input from the
keyboard or new characters from the serial port.
The default (and maximum) size of the history buffer is 8192 characters. You can set this number to a smaller value using
the command:
racadm set iDRAC.Serial.HistorySize <number>
4. Quit the SOL session to close an active SOL session.
