Technicolor COM2000 Integrator's Manual page 19

Each COM46 card contains an RF input, 12 indicator lights, a recessed reset button, and
thumbscrews on either end. The cards are hot-swappable, allowing one card to be serviced
independently of the other cards. In order to remove a card, simply loosen the thumbscrews that
secure the card in place and pull it straight out of its slot.
The RF input on a COM46 card feeds a dedicated DIRECTV tuner bank which is capable of
streaming up to eight Pro:Idiom encrypted HD channels simultaneously over the internal
COM360 Gigabit Ethernet backplane to an installed QAM6 modulator or one of the two Gigabit
Ethernet ports on the COM360 front panel. The COM46 is designed such that each tuner on a card
only needs to be set once. Once configured, the cards should remain locked unless there is a
disruption in the signal due to weather, dish misalignment, or other RF distribution issues.
However, the cards will automatically recover when the disruption to the RF is removed.
The COM46 card only works with DIRECTV input signals in the range of 950 - 2150 MHz as
supplied by a DIRECTV SWiM module. Unlike the legacy COM24 receiver, the COM46 does not
support legacy multi-switch installations. The RF input system must be built with SWiM modules.
