Figure 7 – QAM24 Front View
The QAM24 outputs three unique channel-grouping of four channels each according to the EIA
North American Cable Television Frequency Plan (see EIA-542B) from the front RF connector.
The four channels within each channel-grouping must be adjacent to one another and within the
same band.
The QAM24 card contains six (6) green LEDs on its front panel that indicate power, GbE Link/
Activity, and QAM status, as well as the link-status for each channel group.
The QAM24 card‟s bottom-right LED represents the board‟s power (PWR) state, lighting
up once all on-board power regulators report the “good” state, and going dark when power
is removed from the chassis or when a problem is detected on one of the regulators.
The QAM24 card‟s middle- right LED represents the link and activity of the GbE interface
on the back of the card.
The QAM24 card‟s top- right LED represents the status of the QAM24 card. It is solidly-lit
when the card is performing a software update. It is flashing if an over-temperature
condition is detected on the card.
The QAM24 card‟s left LEDs represent the link-status for each of the 3 channel groupings.
The QAM24 card contains a recessed button on its front panel to be used as a dedicated
hardware reset for the FPGA processor. To complete an upgrade of the FPGA firmware a power
