Power Supply Module Overview
The switch operates with either one or two active power supply modules. You can use two AC modules, or
one module and a blank cover.
The Catalyst 2960XR-48FPD-I and 2960XR-48FPS-I only support the PWR-C2-1025WAC power supply.
You cannot use the PWR-C2-250WAC and PWR-C2-640WAC power supplies in these switches.

The 250-W and 640-W AC power supply modules are autoranging units that support input voltages between
100 and 240 VAC. The 1025-W power supply module is an autoranging unit that supports input voltages
between 115 and 240 VAC. All power supply modules have internal fans. All switches ship with a blank
cover in the second power supply slot.
Each AC power supply module has a power cord for connection to an AC power outlet.
