OpenCS

OpenCS will be an open-hardware (and open-source) console server project.

Specs

• 1U rack-mount chassis with 8 slots (4 front, 4 back) connected by an internal backplane
  • Slots will ideally all be equivalent so users can put power/ports where they want them, can be filled with:
    • a PSU (up to two per system)
    • a controller (up to two per system)
    • an expansion module (lets you chain more chassis, up to two per system)
    • an I/O module (gives you serial ports)
• SPI between modules with module select pins shifted by one by the backplane for each slot* Fully-expanded base chassis would be two PSUs, two controllers, and 4x 8-port RS232 modules.
• Controllers will have an Ethernet port and two serial ports on them (console/aux)
  • Probably PIC32-based makes the most sense
• I/O modules will have up to 8 serial ports on them
  • Probably CPLD-based makes the most sense
