 You should have set up your BIOS for console redirection earlier, so now we will do the bootloader and init. You should have set up your BIOS for console redirection earlier, so now we will do the bootloader and init.
  
-To allow your bootloader to redirect over the BMC's serial port, edit /​boot/​grub/​grub.conf,​ sometimes known as /​boot/​grub/​menu.list add the following lines to grub.conf or menu.list:+To allow your bootloader to redirect over the BMC's serial port, for Grub v1, edit /​boot/​grub/​grub.conf,​ sometimes known as /​boot/​grub/​menu.list add the following lines to grub.conf or menu.list:

 This gives you a serial console on the second serial port, which should be your BMC's serial port, at 19200Kb per second, which should match what you chose in the BIOS. The order of the console options above is important. The last listed will be the system'​s default console which will display the boot messages and kernel errors. This means that after halfway through the boot process, during shutdown and when there are kernel errors, only the serial console will see the messages. As you want to work remotely, this is the way it has to be. You can't have more than one default console. You can however interrupt grub at boot time and edit the kernel line for a single boot with different parameters if you need to see the default console locally but remember that they will persist until you reboot, which means that if you reboot but still want to see them locally, you'll have to interrupt and edit grub at boot time again and also, to see them remotely again, you need to remember to reboot. This gives you a serial console on the second serial port, which should be your BMC's serial port, at 19200Kb per second, which should match what you chose in the BIOS.
