User Manual DEV 2190
At the rear side on the right, the faceplate (labeled P) is installed holding the power
plugs with fuse holders and the grounding bolt. Left to the CPU module (C, chapter
3.2.3) five horizontal slots are available.
The upper slot (Top Slot) is usually reserved for the RF input ports of the device. If
the chassis is equipped with combiner options (chapter 3.1.5), the output ports of
the corresponding amplifier modules are located here.
Slot 1...Slot 4 accommodate the output ports of the device if equipped with
amplifier options (chapter 3.1.3), distribution options (chapter 3.1.4), or with IRD
controlled switch options (plus possibly installed IRD controlled switch option
extensions, chapter 3.1.6). The slots may accommodate input ports if equipped
with combiner options; and alternatively, pre-divider options (chapter 3.1.8) can be
installed here.
Slot 1...Slot 4 can be used for the RF output (input) ports of distribution (combiner)
options; up to eight 1:4 splitters (eight 4:1 combiners), or up to four 1:8 splitters
(four 8:1 combiners), or up to two 1:16 splitters (two 16:1 combiners), or one 1:32
splitter can be located within one slot. Larger distribution options need the corre-
sponding number of slots (64 outputs: two slots; and 128 outputs: all four slots).
Alternatively, a slot can be used for the RF output ports of IRD controlled switch
options; an IRD controlled switch option with 16 output ports requires one slot.
Larger IRD controlled switch options need the corresponding number of slots
(32 output ports: two slots; 48 output ports: three slots; and 64 output ports: all
four slots).
To hard-wire the output of one polarization/band to a corresponding splitter with 8
(or 16) output ports, up to four IRD controlled switch option extensions are
possible in addition to IRD controlled switch options with less than 64 (or 48)
output ports.
Finally and as mentioned, each of the four slots can be used for the installation of
pre-divider options.
Note:

Within the Top Slot, the input ports (or the output ports in case of combiner
options) are installed from left to right, following the slot numbering of the
front side. With applied redundant amplifier options (chapter 3.1.7) in case of
Option 23, the input numbering follows the sequence of the amplifier module
installations at the front side and in case of Option 24, the input numbering
follows the redundancy unit numbering.
