How EMP Console Works
The EMP shares use of the COM2 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 COM2 port. The following discussion covers how EMP Console functions in
each mode:
• Command mode is the default COM2 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.
