Power-Supply Modules
The 24- and 48-port switches are powered through an internal power-supply module. The “24- and 48-Port Switch Power-Supply Modules” section on page 1-15and Table 1-11describe the supported power-supply modules for the switches.
The Catalyst 3560E-12D and 3560E-12SD switches are powered through two internal power-supply modules. The “Catalyst 3560E-12D and 3560E-12SD Switch Power-Supply Modules” section on page 1-16and Table 1-13describe the supported power-supply modules for the switch.
24- and 48-Port Switch Power-Supply Modules
The 24- and 48-port switches have one internal 265-W, 750-W, or 1150-W power-supply module
(Table 1-11). The 265-W and 750-W AC-power-supply modules are autoranging units that support input voltages between 100 and 240 VAC. The 1150-W power-supply module is an autoranging unit that supports input voltages between 115 and 240 VAC. The DC-power-supply module has dual input feeds (A and B) and supports input voltages between 36 and 72 VDC.
The AC-power-supply modules have a power cord for connection to an AC power outlet. The 1150-W and 750-W modules use a 16-AWG cord (only North America). All other modules use an 18-AWG cord. The DC-power-supply module requires wiring to a DC-power source.
For switches connected to an RPS 2300, the RPS 2300 powers the switch when the power-supply is removed or fails. When a new switch power supply is inserted, the switch software polls the device. The switch power supply then automatically resumes providing power, and the RPS 2300 is available to power other devices.
