Supports up to 72 QAM channels (Annex A/C) or 192 Annex B channels. Ingest Capacity:
The chassis includes six slots for QAM cards, each typically supporting multiple RF ports.
Assume you have a D5 with a single module in slot 2, and you need to inject a new UDP stream (IP 239.1.1.100, port 1234) into RF Channel 500 MHz (QAM256).
🔥 : If "hot" refers to a troubleshooting issue (overheating), check the fan redundancy status in the NMS or ensure the 2 RU chassis has clear airflow for its six modulator slots. If you'd like to dive deeper into a specific area: Configuration steps for multicast or scrambling. Hardware specifications for QPM modules. Firmware-specific features for your current release.

Veteran techs know the D5’s hidden danger:
The ARRIS D5 is a (Quadrature Amplitude Modulation). It takes digital video streams (MPEG-2, MPEG-4, or IP video) and converts them into RF signals that can be sent over coaxial cable to TVs.
| Feature | Specification | |---------|----------------| | | 2RU (19” rack) – Holds up to 2x QAM modules | | Max QAM Channels | 256 Annex B (or 384 Annex A) per chassis | | RF Output | 50 – 1002 MHz; Typical level: 37 dBmV (±2) | | Inputs | GigE (SFP) – GbE1/2, optional 10GbE | | Protocols | UDP, RTP, MPEG-2 TS, DOCSIS 3.0 (DEPI) |
