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 10 Gbps, with combination
copper/fiber uplink ports. PoE connections and options for adding 10-Gbps or 100 Gbps uplink
connections are available on some models. Many Summit switches include high-speed stacking
interfaces that allow you to connect up to eight Summit switches into a single SummitStack
management entity. Summit models are available for AC or DC power connection; all Summit switches
make provision for redundant power supplies. Most models have connections for optional external
redundant power supplies; the Summit X650 series switches provide two bays for pluggable power
supplies.
Table 3 and Table 4 list the Summit switch series and summarize the features available in each series.
