The above figure shows the EMP window in redirect state with the terminal window.
The text that appears on the server monitor displays in the redirect window.
Availability of the various EMP features is determined by two things: the EMP access
mode selected during configuration in the System Management Submenu of the BIOS
Server Menu, and if the server's COM 2 port is configured for console redirect in BIOS.
The three EMP access modes are disabled, pre-boot, and always active.
