Connecting the Switch in a Stack Configuration
ESP630 supports two stacking topology configurations, the line and the ring topologies. In line-topology,
there’s one cable connecting each switch to its neighbors. In ring-topology, a redundant path is formed by
an extra cable connecting the bottom switch to the top switch of the stack. Stacking connections should be
made using 27 and 28 10/100/1000Base-T ports only and category 5 or better UTP/STP cables.
