Caution: It is mandatory that the air flow across an Eclipse Pico
matrix is unimpeded. The air flow in a standard 19-inch
(48.26 cm) rack should be sufficient. If the matrix is mounted
in a portable case, be sure the air flow is not impeded.
Eclipse-32 Matrix
The Eclipse-32 matrix requires one vertical rack unit (1.75 in. or 44.45
mm) in a standard Electronics Industry Association 19-inch (48.26 cm)
rack. A temperature-controlled fan cools the Eclipse-32 and forces air
through the unit horizontally. An alarm light on the front panel of the
Eclipse-32 alerts the system operator when the temperature-controlled
fan activates.

INTERFACE FRAME(S) AND POWER SUPPLIES
Interface modules convert the 4-wire signals of a central matrix port to
some other form of communication, such as for telephones, camera
intercoms, two-way radios, and so on. In this way, non-4-wire devices
can communicate with the central matrix.
Each interface module connects to both the central matrix and to the
non-4-wire device through cable attached to hardware connectors on
the rear of the interface module. To house these interface modules,
Clear-Com offers three types of interface frames, which are described
in the following sections.
IMF-3 Interface Module Frame
The IMF-3 interface frame holds up to 11 interface modules in three
rack units (3 RU) of a standard Electronics Industry Association
19-inch wide (48.26 cm) rack. The frame holds a modular,
rear-mounted connector panel for each interface, containing two RJ-45
connectors for connecting cable to matrix ports, and two DB-9
connectors for connecting cable to non-4-wire devices. Figure
2-1illustrates the rear panel of an IMF-3 interface frame, with 11
rear-panel assemblies installed.
The frame uses an external PSU-101 rack-mounted power supply to
supply power to the interface modules. A second PSU-101 can be
attached for redundancy.
