Installation Notes for Catalyst 3750-E, Catalyst 3560-E Switches and RPS 2300 Power Supply Modules
78-17570-01
Product Overview
Product Overview
Table 1 describes the power supply modules.
Table 2 describes the supported power supply modules for the switches and the RPS 2300.
For more information about which RPS 2300 power supply modules to use for specific switch support,
see the Cisco Redundant Power System 2300 Hardware Installation Guide.
The 750-W and 265-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 include 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.
