For more information on the IMF-3 frame, refer to its manual in the
Eclipse manual set.
Figure 2-1: IMF-3 Interface Frame Rear Panel
Note: The IMF-3 frame has an individual rear panel for each
interface. All interfaces use the same rear panel; however
the use of the rear-panel connectors will vary with the type
of interface.
Each interface features indicators and controls that must be accessible
to operators, so put the interface module frame(s) in a convenient
location. Usually interface module frames are located near the matrix
frame, but they can be located farther away. The maximum distance
between the matrix frame and the interface frame is 500 feet (150
meters).
Each Eclipse frame contains its own power supplies and does not
supply any power for interfaces. A separate power supply (PSU-101) is
only necessary for interfaces mounted in IMF-3 frames. If redundant
power supply pairs are used for interfaces, mount them together.
It is required that you leave an extra rack unit (1.75 in. or 44.45 mm)
above and below each external power supply unit. This allows for
needed cooling for larger system loads.
IMF-102 Interface Module Frame
The IMF-102 interface frame has slots for two interface modules in one
rack unit (1 RU) of a standard Electronics Industry Association 19-inch
wide (48.26 cm) rack.
It has an internal power supply and a connector for a redundant power
supply. The IMF-102 requires 90 to 250 VAC with a maximum
dissipation of 20 watts.
Its rear input/output connector panel has two RJ-45 connectors and
two DB-9 connectors for the two interface modules. Figure 2-2
illustrates the rear panel of an IMF-102 interface frame, with two
installed rear-panel assemblies.
