Power Supply Module Overview
The input voltages of the power supplies are as follows:
• The 250-W, 640-W, and 715-W AC power supply modules are autoranging units that support input
voltages between 100 and 240 VAC.
• The 1025-W and 1100-W AC power supply modules are autoranging units that support input
voltages between 115 and 240 VAC.
• The 640-W DC power supply module has dual input feeds (A and B) and support input voltages
between 36 and 72 VDC. The output voltage range is 51 to 57 V.
Each AC power supply module has a power cord for connection to an AC power outlet.
• The 640-W, 715-W, 1025-W, and 1100-W and modules use a 16-AWG cord (only North America).
All the other modules use an 18-AWG cord.
• The DC power supply module must be wired to a DC power source.
Note • For information on 250-W AC power supply support on the PoE-capable switch models, see the
Cisco Catalyst 3650 Series Switches Release Notes at
http://www.cisco.com/c/en/us/support/switches/catalyst-3650-series-switches/products-release-not
es-list.html.
• Only the DC power module is NEBS-compliant.
.Figure 4-1 to Figure 4-6 show the power supply modules.
