Switch specifications
Every switch in the catalog, with the data that actually drives a fabric design: logical ports against physical cages, breakout, power and rack units.
Read two of these columns together. Ports is the logical port count; cages is how many physical modules the switch actually takes. Where they differ, each cage carries a twin-port module terminating two links, so ordering one optic per logical port buys twice what the switch can hold.
