"i" Series Switch Hardware Architecture

The BlackDiamond Systems

In the context of the advanced system diagnostics suite, the BlackDiamond family of core chassis
switches share the same fundamental hardware architecture: a multislot modular chassis containing a
passive backplane that supports redundant load-sharing, hot-swappable switch fabric modules. On
BlackDiamond systems, each I/O module and MSM represents an individual switch containing its own
switching fabric and packet memory.

BlackDiamond 6800 Series Hardware Architecture Differences

In the context of understanding the ExtremeWare diagnostics and their use in troubleshooting system
problems, these are the key hardware distinctions between the BlackDiamond 6816, 6808, and 6804.
• BlackDiamond 6816—Modular chassis with passive backplane; sixteen chassis slots for I/O modules;
four chassis slots for MSMs.
• BlackDiamond 6808—Modular chassis with passive backplane; eight chassis slots for I/O modules;
two chassis slots for MSMs.
• BlackDiamond 6804—Modular chassis with passive backplane; four chassis slots for I/O modules;
two chassis slots for MSMs.
