Configuration, State, and Alarm Data
The Chassis Control Module stores configuration files for all DOCSIS Modules and itself.
When a module boots, the Chassis Control Module sends the appropriate configuration file to
that module. Configuration files are ASCII text in a format readable by the command-line
interface. Users can edit these files on the CMTS or on an external host with any standard
text editor (see the
JUNOSg Software Configuration Guide: Getting Started and System
Management
for more information on configuration). The Chassis Control Module also
provides configuration data to management applications.
The Chassis Control Module polls each DOCSIS Module for state information, then stores that
data. This includes ranging and registration data on the cable modems and a backup of the
DOCSIS Modules’ memory and tables. Polling occurs at regular intervals to keep the data
current.
The Chassis Control Module collects and stores events from itself and the DOCSIS Modules
within the local event log. It uses this information to control the LEDs and provides this data
to management applications.
The Chassis Control Module monitors the power supplies for the failure and degraded
performance signals that they generate.
The Chassis Control Module monitors the fans for failures. If a fan in any of the multifan trays
fails, the module sends a signal to increase the speed of the remaining fans and conditionally
generates an event.
Physical and Electrical Characteristics
This section describes the physical dimensions, electrical characteristics, and components of
the front panel of the Chassis Control Module. See Table 11 through Table 14 on page 41.
The Chassis Control Module installs into the chassis from the front. Midplane slots 6 and 7
are designated for this module. One module is required to manage the chassis.
Each Chassis Control Module consumes 29 watts maximum power.
