Configuring the 9F120-08 FDDI Concentrator Module
The 9F120-08 is an FDDI concentrator for use with single attached FDDI nodes,
such as a UNIX workstation or Þleserver. It has eight industry standard FDDI
MIC MMF Master ports. A MUX on the 9F120-08 allows the module to dual-
attach to FNB-1 primary or secondary and FNB-2 primary or secondary. Each
master port on the module can be individually assigned to one of the two rings to
which the module is connected, as can the moduleÕs MAC encoding. To alter the
9F120-08Õs backplane attachment:
1.
In the BackPlane Configuration view, click the left mouse button on either
FNB-1 or FNB-2 in the middle of the 9F120-08 module front panel display.
The FNB Configuration window (Figure 3-8) will appear.

2.
Connect the module to FNB-1 and FNB-2 by clicking the left mouse button on
the appropriate, color-coded ring switch symbol (
— blue for FNB-1
primary, green for FNB-1 secondary; magenta for FNB-2 primary, yellow for
FNB-2 secondary). FNB rings to which the module is connected will be
elongated.
3.
Associate the master ports with one of the two FNB rings to which the module
is connected:
a.
Click the left mouse button on a port index to the right of the FNB
configuration window. A pull-down menu will appear.
b.
Drag to the appropriate option: FNB-1 Primary/Secondary or FNB-2
Primary/Secondary.
Color-coding of each port index will reflect the associated ring.
