Clear-Com HX System Frames - Manual (Page 22)

4.1.2 Locating the Eclipse HX-PiCo
The Eclipse HX-PiCo matrix (matrix frame) requires one vertical rack unit (1RU) (1.75 in.
or
44.45 mm) in a standard Electronics Industry Association 19-inch (48.26 cm) rack.
Cooling the matrix frame
A temperature-controlled fan cools the Eclipse HX-PiCo and forces air through the unit
horizontally. An alarm LED on the front panel of the Eclipse HX-PiCo alerts the system
operator when the temperature-controlled fan activates.
Environmental information:
The air flow across an Eclipse HX-PiCo matrix must be 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.
4.2 Locating interface frame(s) and power supplies
Interface modules convert the four-wire audio signals from the matrix frame into audio
formats for telephones, camera intercoms, two-way radios, analog partyline systems, and
other communication devices. In this way, non-four-wire devices can communicate with the
matrix.
In addition to 7 slots for circuit cards (CPU and interface cards), the 6RU Eclipse HX-Median
matrix frame has slots for up to 8 interface modules. The 3RU Eclipse HX-Delta matrix frame
has 4 slots for circuit cards, and slots for up to 3 interface modules.
Clear-Com also offers two types of interface frame to host interface modules:
4.2.1 IMF-3 interface 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 rear connector panel for each interface module, comprising:
• Two RJ-45 connectors for connecting with the matrix frame.
• Two DB-9 connectors for connecting cable to non-four-wire devices
(see Figure 2: IMF-3 rear panel).
