Overview

Summit family switches are shipped with an internal power supply that supplies all of the power
needed for most switch operation. An optional redundant power supply can be added to protect against
a power supply failure and to provide increased support for PoE operation on applicable switches.
Table 11 lists the Summit family switches and compatible external power supplies.
