How the EMP Console Works
The EMP shares theCOM2 port with the system. When the EMP has controlof the port,
the port operates in command state. When the system has controlof it,the portoperates
in redirect state. When connecting to a server, the EMP console checks to determine the
current COM2 port state. See Figure 3-5 for and example screen of the EMP console in
command state and Figure 3-6 for an example of the EMP console in redirect state.
• Command state—the default COM2 state. In this state, the EMP console
communicates with the server’s firmware, allowing the client to remotely reset or
power the server up or down. The client can also view the server’s SEL, FRU
information, or SDR table.
• Redirect state—the EMP console serves as a PC ANSI terminal window for BIOS
console redirection. Commands typed in this terminal window are transmitted
through BIOS to the server’s console, and text displayed on the server console is
displayed on the EMP console’s terminal window. With the EMP in this state, you
can remotely view boot messages, access BIOS setup, and run DOS text mode
applications through the EMP console’s terminal window.
