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.

Figure 3-1to Figure 3-4show the power supply modules.
