Chapter 2: First Time Installation

To turn Service On, simply go to the Home screen, locate the box titled General Settings,
(below the right side of the BU) and click on the top circle, marked Service. The circle will
light green to indicate that Service is now On.
One important feature of turning Service On is Calibration. Calibration fine tunes the system
by having it detect the path loss of all RF pathways and adjust internal parameters
accordingly, thus achieving optimum system performance. Although ZoneDAS can
operate without the benefit of calibration, performance will be affected adversely.
Calibration, therefore, is an important part of proper ZoneDAS installation.
As mentioned, simply turning on Service applies a System Calibration. However, if RUs or
Extenders get unplugged and re-plugged into different ports without turning off Service,
manual calibration may be necessary. Activating System Calibration manually is easy.
Simply go to the Home screen (by pressing Home on the Navigation Panel), locate the box
titled General Settings, (below the right side of the BU) and click on the bottom circle,
marked System Calibrate, as shown below.

Just as the on-screen lines connecting the BU to the RUs turn yellow when each RU is
mounted, each line turns green when calibration is complete for that connection—and red
when calibration fails there. It is important to ensure that all lines are green by the end of
this calibration stage. If a line is not, it may become necessary to check for cable
quality/connection or for alarms and resolve them.
Note that the system will not operate while it is calibrating! During the half minute or so that
the system takes to calibrate everything, it is effectively under maintenance. Note also that
any unmounted connections will not receive system calibration.
2.3.10 Fill in Descriptive Information
Now that the system is operating, it is time to prepare it for management. The first step,
which everyone should do, is to identify all the relevant parts. The second step, only for
those who require central management, is to connect to the server. Here let us take care
of the first step.
To identify all the relevant parts, we must give names (and codes) to the BU and all the RUs.
To name the BU, go to the BU screen (click on Home and then on the BU), find Site name
and Site code near the screen’s upper left, and fill in their values.
