Technicolor - Thomson 8900NET Benutzerhandbuch

Software updates can be made to the 8900NET ROM through the Web-
based interface. Non-volatile RAM is provided to store key setup values 
when power is cycled.

The 10Base-T Ethernet port provides configuration and monitoring access 
to the frame, frame modules and the 8900NET module using a Web 
browser.

The RS-232 port is used to initialize the module with critical network 
parameters including a static assigned IP Address. Ethernet MAC address 
is stored on a serial EPROM on the frame. (The frame needs both MAC and 
IP Addresses.)

The Module Health bus connects all the audio/video module cells to the 
microprocessor. It is used to report module faults or data errors.

The Frame Bus provides serial communication to each of the audio/video 
modules for remote configuration and monitoring over a network.

Module Present lines from cells 1 through 10 and Present/Health lines 
from cells 12 and 13 are monitored by the microprocessor using the Module 
Present Detection circuitry. For cells 1 through 10, this circuit reports to the 
processor whether a module is present and if it supports frame bus com-
munications (control and monitoring). For cells 12 and 13, this circuit 
reports if the power supply is present and if it is working properly.
