Chapter 3 Power Supply Installation
Power Supply Module Overview
For information on available PoE, see these sections:
•Table 1-10 on page 1-18(available PoE with AC power supply)
•Table 1-11 on page 1-18(available PoE with DC power supply)
•Table 1-12 on page 1-18(switch power supply requirements for PoE and PoE+)
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. The 640-W DC power supply module has dual input feeds (A and B) and supports input voltages between -36 and -72 VDC.
Note For information on 250-W AC power supply support on the PoE-capable switch models, refer to the Release Notes for the Cisco Catalyst 3650 Switch on Cisco.com.
Each AC power supply module has a power cord for connection to an AC power outlet. The 1025-W and 640-W modules use a 16-AWG cord (only North America). All other modules use an 18-AWG cord. The DC power supply module must be wired to a DC power source.
