Hot-swappable QAM Modules
The APEX1000 supports up to three hot-swappable QAM modules:
Each QAM module has two RF output ports, each of which supports either four or eight
adjacent QAM carriers. The 2x4 QAM modules support up to four QAMs per port and
the 2x8 QAM modules support up to eight QAMs per port, allowing the following
configurations:
•
When three 2x8 QAM modules are installed, the APEX1000 supports up to 48 QAM
channels (six RF outputs, each carrying up to eight QAM channels)
•
When three 2x4 QAM modules are installed, the APEX1000 supports up to 24 QAM
channels (six RF outputs, each carrying up to four QAM channels)
CAUTION All QAM channels on a given RF output must be assigned to adjacent carrier frequencies
and must be assigned the same modulation mode, all either 64QAM or 256QAM.
QAM Module Ordering Options
Customers typically order one of four package configurations of the APEX1000. The first
two package configurations (1 and 2) include the chassis and three (2x8) RFPM modules.
Configuration 1 includes a single AC power supply module and Configuration 2 includes a
single DC power supply module. The last two package configurations (3 and 4) include
the chassis and three (2x4) RFPM modules. Configuration 3 includes a single AC PS
module and Configuration 4 includes a single DC PS module.
•
If you want to use dual-redundant power supply, order any one of the package
configurations and the second power supply module separately. An APEX1000
chassis supports either one AC PS module, one DC PS module, two AC PS modules,
or two DC PS modules. (The APEX1000 does not support the inclusion of both one
AC and one DC PS module at the same time.)
•
If you do not want to use one of the fixed package configurations, you can build your
own custom configuration by ordering the APEX components individually. You can
order the chassis, either one, two, or three RFPM modules (each either 2x4 or 2x8),
and either one or two PS modules.
Note: For Annex A, High Density modules provide a 2x6 instead of a 2x8 configuration.
