System Console Selection
Each operating system requires that the correct console type be selected from the firmware selection
menu. The following section describes how to determine the correct console device.
If an operating system is being installed or the system configuration is being changed the system
console setting must be checked to ensure it matches the hardware and OS. Not checking the
console selection can result in the system using an unexpected device as a console, which can
appear as a system hang when booting.
1. Determine the console you want to use.
Depending on your operating system and your hardware you can select one of two possible
devices as your system console. The possibilities are:
• Management Processor (MP) Serial Port
• VGA device
