Summit Power Supplies
This chapter describes Extreme Networks power supplies available for use with the Summit family
switches.
This chapter includes the following sections:

Overview
Summit family switches are shipped with an internal power supply (replaceable on the Summit X460,
X480, X650, and X670 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.
The following Summit switch series use external power supplies for redundancy:
● Summit X150 series
● Summit X250e series
● Summit X350 series
● Summit X450 series
● Summit X450a series
● Summit X450e series
The following Summit switch series provide power redundancy by installing a second replaceable
power supply:
● Summit X460 series
● Summit X480 series
● Summit X650 series
● Summit X670 series
