After the network management port has been assigned an IP address by a DHCP server, you can connect to the ALOM system controller using Secure Shell (SSH). As an alternative to the (default) DHCP configuration, you can configure the network management port with a static IP address and change the communication protocol from SSH to Telnet. Up to eight simultaneous connections to the system controller sc> prompt are available through the network management port. For more information, see “Activating the Network Management Port” on page 4.

Accessing the System Controller

This section describes ways of accessing the system controller.
