130 Maintaining and Troubleshooting the Gateway ALR 9200 Server
How the EMP Console Works
The EMP shares the COM2 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 COM2 port state.
•
Command state—the default COM2 state (Figure 34). In this
state, the EMP console communicates with the server firmware,
allowing the client to remotely reset or power the server up or
down. The client can also view the server SEL, FRU information,
or SDR table.
