These mechanisms are described more fully in the next sections.

Terminal Connection

Direct access through the Console port is often preferred because it allows you to remain on the system during system boots. A Macintosh or PC attachment can use any terminal emulation program for connecting to the Console port. A workstation attachment under UNIX can use the emulator TIP or you can attach a terminal.

For more details, see the documentation that is shipped with your terminal emulation program.

Modem Connection

To access the system through a modem, establish a connection between your workstation and the Console port. When you configure the external modem from the Administration Console menu system, the Console appears to be directly connected to the external modem. See the Command Reference Guide for more information.

Use the Console port for either a terminal connection or a modem connection.

IP Management Interface

An IP interface is the connection between the CoreBuilder 9400 system and a subnetwork. Use the IP interface to manage the system in two ways:

■In-band— Through a Gigabit Ethernet port

You can use this port for switching and managing the system simultaneously.

This method decreases the total bandwidth available on the port for switching.

■Out-of-band— Through the 10BASE-TX port that is located to the left of the Console port

You can use this port only to manage the system, not for switching network traffic. Managing your system out-of-band conserves all available bandwidth for the Gigabit Ethernet ports. Also, if network problems exist, you can manage the system from a different network. See the Implementation Guide for more information on in-band and out-of-band management.
