How EMP Console Works
The EMP shares use of the COM 2 port with the system on the server. When the EMP has control
of the port, the port operates in command mode. When the system has control, the port operates in
console redirect mode. When connecting to a server, the EMP Console checks to determine the
mode of the COM 2 port. The following discussion covers how EMP Console functions in each
mode:
• Command mode is the default COM 2 state. In this state, 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 System Event Log (SEL), Field Replaceable Unit (FRU)
information, or Sensor Data Record (SDR) table.
• In console redirect mode, 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. In this mode, you can remotely view boot messages, access BIOS
setup, and run DOS text mode applications through the EMP Console’s terminal window.
