Overview

Summit family switches are shipped with an internal power supply (replaceable on the Summit X650
series switches) that supplies all of the power needed for most switch operation. An optional redundant
power supply can be added to most Summit models to protect against a power supply failure and to
provide increased support for PoE operation on applicable switches.
Table 13 lists the Summit family switches and compatible external power supplies.
