1.For full 15.4W support on a 48-port PoE+ switch, you must use a C3KX-PWR-1100WAC power supply module.

2.This module is used only in Japan.

Table 3-3	Switch Power Supply Requirements for PoE and PoE+
PoE Option		24-Port Switch	48-Port Switch
PoE (up to 15.4 W per port)		one 715-W power supply	one 1100-W power supply
		two 440-W DC power supplies
PoE+ (up to 30 W per port)		one 1100-W power supply	one 1100-W power supply plus one
			715-W power supply
			or
			two 1100-W power supplies

Note A 48-port switch with one 715-W power supply provides up to 7.7 W of PoE to all ports.

The 350-W and 715-W AC power supply modules are autoranging units that support input voltages between 100 and 240 VAC. The 1100-W power supply module is an autoranging unit that supports input voltages between 115 and 240 VAC. The 440-W DC power supply module has dual input feeds (A and B) and supports input voltages between 36 and 72 VDC. The output voltage range is 51 to 57 V.
