How the EMP Console Works

The EMP shares use of the COM 2 port with the system. When the EMP has control of the port,
the port operates in command state. When the system has control of it, the port operates in redirect
state. When connecting to a server, the EMP Console checks to determine the current COM 2 port
state. The following discussion covers how the EMP Console functions in each state:
Command state is the default COM 2 state. In this state, the EMP Console communicates with
x
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 redirect state, the EMP Console serves as a PC ANSI terminal window for BIOS console
x
redirection. Commands typed in this terminal window are transmitted through BIOS to the
server's console, and text displayed on the server console are 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.
