How the EMP Works
The EMP shares use of the COM 2 port with your 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 checks to determine the current COM 2
port state. The following discussion covers how the EMP functions in
each state:
„
Command state is the default COM 2 state. In this state, the EMP
communicates with the server, 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 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 are displayed on the EMP'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's terminal window.
