The board broadcasts data packets simultaneously to all remote racks, where downstream VCMI modules extract their assigned data. TMR operation uses three IONet channels with SIFT voting to maintain synchronized communication paths. Firmware flash compatibility resides entirely in the controller; the VCMI board contains no programmable flash and performs passive communication routing. I\/O density scaling is achieved through fixed fiber‑optic IONet timing and stable backplane arbitration.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Are earlier revisions of the IS200VCMIH2BEE backwards‑compatible?\u003c\/strong\u003e A: Yes.
