36 JUNOSg 3.0 G10 CMTS Hardware Guide
This section describes the physical and electrical characteristics of the DOCSIS Module. See
Table 8 through Table 10.
The DOCSIS Module installs into the chassis from the front and spans two midplane
connector columns. The module includes the RF upconverter and modem subassemblies.
The module connects to the midplane through connectors J1 through J5. See "Card Cage and
Midplane" on page 21 for related information.
The front panel connectors are not used.
Each DOCSIS Module with its subassemblies consumes 120 watts maximum power.
