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.

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.

Using
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.
