Multi-chassis interconnectivity #5

Open prasimix opened 5 years ago

prasimix commented 5 years ago

This task is initiated by mentioning isolated Ethernet in #4. It does not require immediate attention, but should be of interest when we exceed BB3's three modules limit (better sooner, then later :). The next chassis could be "signaling" only, i.e. does not include space for AC/DC conversion, TFT display and can in that case house 6 to 7 modules. One of them should be "slave" module capable to communicate with master chassis (one that has "local console"). Existing BB3 MCU module provides only 10/100 Mbits Ethernet and USB 2.0 as mean of communication with external world. Perhaps it Ethernet could be replaced with our "Ethernet" alternative.

ethernet: use passive optical hub and it will be ok more difficult for to the firmware but workable though...
