Unit Overview
The unit is designed to offer operators a high level of reliability and flexibility. It
consists of a chassis in which a number of hot-swappable modules can be installed.
In order to match specific system requirements, the chassis can be configured to host
the functional modules best suited for a given scenario.
Appear TV products can be delivered in two different chassis variations; a 1 RU
chassis and a 4 RU chassis. The product description DC1000, SC2000 and MC3000
represents the 4 RU chassis, while the product description DC1100, SC2100 and
MC3100 represents the 1 RU chassis. Both chassis variations use the same HW
modules and run the same SW.
The 4RU chassis consists of a total of 18 slots which can all host functional modules.
Slot number zero is dedicated to host the switch module and slot number 17 can only
host multi-slot functional modules except the HP DUAL DECODER RF MOD STEREO
and the QAM OUTPUT modules. Alternatively, in a DC1000 configuration, a second
switch module can be placed in slot 17. The remaining 16 slots are identical and can
be occupied by any of the functional modules available. A 4 RU chassis including a
mandatory switch module, power supply connectors, and module slots is shown in
Figure 1. Power modules and switch modules are inserted from the back (not shown).
Figure 1 – 4RU chassis with power connectors, switch module and available slots.
The 1RU chassis consists of a total of 9 slots plus a slot for the switch module.
Modules can be inserted from the front and from the back. The modules inserted in
the front are not hot-swappable and can only be serviced by factory or by authorized
service facilities. The modules inserted in the back can be services in the field. The
mandatory switch module is placed in slot 0 located in the front upper right corner
behind the front cover. Slot 1 is in the front below the switch module and slot 8 and 9
are in the front on the right side. Slot number 2 to 7 is in the back as illustrated in
Figure 2. Slot 1 can only support IP IO module or a descrambler module. Slot 8 and 9
can only support descrambler modules. Slot 2 to 7 can hold any 1 or 2 slot wide
module available.
