Overview of the Summit Switches
The Summit family switches are compact enclosures 1.75 inches high (1 U). They provide 24 or 48
high-density copper or fiber optic ports operating at speeds up to 1 Gbps, with combination
copper/fiber uplink ports. Summit switches may offer PoE connections and options for adding 10-Gbps
uplink connections. Many Summit switches include high-speed stacking interfaces that allow you to
connect up to eight Summit switches into a single SummitStack
