NOTE: Run OpenSSH from a VT100 or ANSI terminal emulator on Windows. Running OpenSSH at the Windows
command prompt does not result in full functionality (that is, some keys do not respond and no graphics are displayed).
Before using SSH or Telnet to communicate with iDRAC, make sure to:
1. Configure BIOS to enable Serial Console.
2. Configure SOL in iDRAC.
3. Enable SSH or Telnet using iDRAC Web interface or RACADM.
Telnet (port 23)/ SSH (port 22) client <−−> WAN connection <−−> iDRAC
The IPMI-based SOL that uses SSH or Telnet protocol eliminates the need for an additional utility because the serial to network
translation happens within iDRAC. The SSH or Telnet console that you use must be able to interpret and respond to the data
arriving 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 or Telnet console.

NOTE: If required, you can change the default SSH or Telnet time-out at Overview → iDRAC Settings → Network →
Services.
To start IPMI SOL from PuTTY on a Windows management station:
1. Run the following command to connect to iDRAC
putty.exe [-ssh | -telnet] <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 or Telnet 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.

Using SOL from OpenSSH or Telnet on Linux
To start SOL from OpenSSH or Telnet on a Linux management station:
NOTE: If required, you can change the default SSH or Telnet session time-out at Overview → iDRAC Settings →
Network → Services.
1. Start a shell.
2. Connect to iDRAC using the following command:
• For SSH: ssh <iDRAC-ip-address> -l <login name>
• For Telnet: telnet <iDRAC-ip-address>
NOTE: If you have changed the port number for the Telnet service from the default (port 23), add the port number
to the end of the Telnet command.
3. Enter one of the following commands at the command prompt to start SOL:
