to a switch. This allows access to each individual server system. The system administrator can
remotely switch from one server to another to manage large numbers of servers.
BIOS console redirection supports an extra control escape sequence to switch Serial Port B to
BMC control. The character sequence that switches the multiplexer to the BMC serial port is
“ESC O 9” (denoted as ^[O9). This key sequence is above the normal ANSI function keys and is
not used by an ANSI terminal.
After this command is sent, the Serial Port B attaches to the BMC Channel Access serial port
and Super I/O Serial Port B data is ignored. This feature allows a remote user to monitor the
status of POST using the standard BIOS console redirection features and then take control of
the system reset or power using the Channel Mode features. If a failure occurs during POST, a
watchdog time-out feature in the BMC automatically takes control of the Serial Port B.
18.3.3 Serial Over LAN
The server system must support console redirection via SOL during the entire BIOS POST
process with these requirements:
No loss of characters in the remote console during POST redirection
No garbage characters should be seen.
User should be able to clearly see the POST messages.
Should be able to enter BIOS Setup, select and modify options, and save or discard the
change.
Function keys should work just like the local console.
No momentary loss even during PXE\DHCP negotiation
Should support console redirection (PC-ANSI terminal modes).
Should support all baud rates — 9.6, 19.2, 36K, 56K, 115K.
Performance should be comparable to the local console with no redirection.
The platform supports SOL on Serial Port B that also provides EMP and standard serial
functionality as an external serial port. Since this port is not dedicated for SOL BIOS
Setup options should be provided for configuration when not operating in SOL mode.
Serial Port B configuration when SOL is enabled should all be done via BMC
configuration utilities. The BIOS determines if SOL has been enabled during POST. If
SOL has been enabled then the BIOS enables console redirection on Serial Port B and
sets the baud rate from BMC. The BIOS also sets the term-type to PC-ANSI and flow
control to CTS-RTS.
In addition, operating system console redirection must be supported with SOL for all P1
operating systems with the following requirements:
For example, the user should be able to run shell commands under Linux and should be
able to see the redirected console.
No loss of characters in the remote console during operating system redirection
If the EFI shell is running, to see the EFI Shell prompt on the SOL console, an <Enter>
key must be pressed.
