6-2 CHP Max™ Headend Optics Platform Chassis, Controllers and Power Supplies 1508685 Rev D
Local Monitoring
A computer with Craft Management Software is used to monitor a single CHP Max5000 chassis
through a direct RS-232 connection to either the CMM or SMM controller module. The
controller module sends management signals through the serial peripheral interface (SPI)
bus on the chassis backplane to the other modules installed in the chassis, and status
information from the modules travels back through the same route. The controller module
then communicates with the computer running the Craft Management Software.
Auto Config
Auto Config (auto-configuration) refers to the management module in the shelf making
changes to the configurable settings of an application module without user intervention. For
example, when an application module in a shelf with an original CMM or SMM is replaced,
any changes made to the default alarm thresholds, optical output power, RF attenuator, etc.,
would be lost. The original CMM (P/N CHP-CMM) and SMM (P/N CHP-SMM) modules do not
support Auto Config on the 10 application module or the redundant power supplies in a
shelf.
In August 2006, ARRIS released the Auto Config version of CMM (P/N CHP-CMM-1) and SMM
(P/N CHP-SMM-1) modules. These new management modules contains a large flash memory
to store the configurable parameters such as alarm thresholds, optical output power, RF
attenuator, etc., based on slot location for each of the 10 application modules and power
supply(s). This Auto Config feature allows you to replace an Auto Config supported module
without cumbersome setup and the management module will automatically restore the
configurable parameters of the previously installed module. In order to use the Auto Config
feature, the following requirements must be met:
■ Auto Config management module (P/N CHP-CMM-1) must be installed
■ Auto Config for an individual shelf does not require the SMM-1 module
■ Do not attempt to install CMM-1 firmware onto a CMM module
■ Auto Config supported application modules listed in Table 6.1 must also be installed
