What the ALOM System Controller Console Does

If it receives no user input within 60 seconds, the ALOM system controller console automatically connects to the system console. To return to the ALOM system controller, type the console escape sequence #.
Using the System Console
To use the system console, you need to attach an I/O device to the server module or the chassis. Initially, you might have to configure that hardware, and load and configure appropriate software as well.
You must also ensure that the system console is directed to the appropriate port, generally, the one to which your hardware console device is attached. You do this by setting the
Default System Console Connection Through the Serial Port and Network Management Ports
On your server, the system console comes preconfigured to allow input and output only by means of the ALOM CMT system controller. The ALOM CMT system controller must be accessed either through the serial port or the network management port. By default, the network management port is configured to retrieve network configuration using DHCP and to allow connections using Secure Shell (SSH).
Typically, you connect one of the following hardware devices to the serial port:
■Terminal server
■Alphanumeric terminal or similar device
■TIP line connected to another Sun computer
