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.
