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; many models provide
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 X460 series, X480 series, and X650 series switches provide two
bays for pluggable power supplies.
Most Summit models are available in versions that are compliant with the Trade Agreements Act (TAA);
these versions are identified by a -TAA suffix on the model number. Functionally, the TAA-compliant
models are completely equivalent to the matching versions that are not TAA-compliant. In all feature
descriptions, references to a specific Summit switch model also apply to the equivalent TAA-compliant
model.
Table 3 and Table 4 on page 18 and Table 5 on page 19 list the Summit switch series and summarize the
features available in each series.

Model numbers for the Summit switches are in the following format:
<Series>-<number of front-panel I/O ports><port type><internal power supply type>
●The number of ports can be 24 or 48.
●The port type can be t(copper), p(copper providing Power of Ethernet), or x(fiber).
●For models with integral power supplies, the power supply type can be AC (no designation) or DC.
Models with pluggable power supplies can accommodate either AC or DC supplies and have no
power designation in their model numbers.
For example, the Summit X350-24t switch is in the X350 series, provides 24 copper I/O ports, and has
an AC power supply. The Summit X450a-24xDC switch is in the X450a series, provides 24 fiber I/O
ports, and has a DC power supply.
Table 6 on page 20 lists the available switch models in each series.
