Port Configuration System Configuration and Operation

3.4.4 Test and Debug Screen

You can also go from the System Main Screen to a Test and Debug Screen, which allows you
to perform system-level maintenance operations. You can back up the system configuration
onto an external computer after saving and subsequently editing it, an d (if nec essary) you can
restore that configuration to the system. You also can erase the system configuration and
restart the system with a single “zip” command.
The system software also has a built-in debugging utility. However, this utility is only
available to factory software engineers. The system maintenance functions are described in
the “Testing and Debugging” section later in this chapter.
3.5 Port Configuration

3.5.1 Selecting and Configuring Your ports

The System Main Screen lists all system ports. Y ou can acc ess any port from the Ma in Screen
by moving the cursor in the installed interface s c olumn with the arrow keys until the desired
port is highlighted, then press <Enter>. The associated port Main Screen now appears. The
only optional installed interface on the IMACS-200 is the Optical High Speed Data Unit
(OHSU).
Use the arrow keys to move the cursor around in any port screen. When changing port
parameters, some settings require you to enter your own values on the keyboard, whi le other s
allow you to select from a list of pre-programmed option settings.
To enter a user-defined value in a f ield, fi rst high light t hat fiel d by movi ng the cu rsor to it and
press <Enter>. Then, type the desired value on your keyboard and press <Ente r> to stor e it in
that field.
To choose an option setting from a list of displayed options, press <Ente r> with the associated
parameter field highlighted. A series of available option settings now appears for that field.
Use the right-arrow and left-arrow keys to move the cursor to the desired setting, and press
<Enter> to store that setting in the highl ighted field.
Be sure to configure each port according to your networking requirements. From the System
Main Screen, select each port in turn and change the opt ions for that port from its Main Screen.
Select the Save command by pressing “s” after making all the changes for a port, then press
“m” to return to the System Main Screen and choose another port. Similarly configure each
remaining port in your system.
Once configured, the port settings are permanently stored in Non-Volatile Random Access
Memory (NVRAM).
