5. Connect the proper wiring/connector to the
interface module.
The 6NF interface is shown in Figure 25-1.
25.3.2 Software Settings
Once you have completed the hardware installa-
tion/connections, you can configure the 6NF
module using the FOCUS Configuration Software
(FCS). See figure 25-2 for a look at the configura-
tion window of the 6NF module.
The only software setting you need to configure, is
the N value (1-x).
Fig. 25-3 shows how to map a 6NF module. When
setting N for values greater than 2, it is necessary to
leave empty chassis slots to the right of the module.
One empty slot for every 2 values of N greater than
N=2. (i.e. one empty slot for N=3 or 4, two empty
slots for N=5 or 6 etc.).
Note for MV3 systems: when using any setting for
N greater than N=1, it is necessary to shift the
mapped time slot at least 3 time slots to the right of
the module’s physical slot. Please refer to Fig. 25-
3.
25.3.3 Status Indicators
This module has five status indicators as shown in
Figure 25-4. The red/green status LED is green if
the module is functional and red if the module is
non-functional. Top to Bottom & Left to Right,
they are;
Valid Data / Alarm
RX / TX
25.4 Acceptance Test
As noted earlier, we recommend that you initially
install and test the 6NF module in a “test” chassis
(i.e., chassis that are not part of an operating
network). This way, you can quickly perform the
acceptance tests without interfering with a live
network.
To conduct this test, you will need the following:
• One 6NF module
• One 6NF interface
