51.1.2 External PSE4500-A Power System
If PSE4500-A power system is taken as the external power supply of the switch, the
power distribution is as follows:
1) Input voltage: 90 VAC to 160 VAC
z One PSU (power supply unit) of the PSE4500-A power system can provide 1200
W of power.
2) Input voltage: 160 VAC to 264 VAC
z One PSU of the PSE4500-A power system can provide 2500 W of power.
z If the PSE4500-A power modules are in 2+1 redundancy, then each module
provides a power of 1500 W.
51.2 PoE Configuration The Switch 8800 can automatically detect any connected device that needs a remote
power supply and feeds power to this device.
z Depending on your actual network requirement, you can set the maximum PoE
power totally supplied by the switch through the command line.
z You can set the maximum PoE power supplied by a card through the command
line.
z You can also control the PoE on each PoE port independently through the
command line. The control includes: enabling/disabling the PoE feature, and
setting the maximum PoE power, the PoE mode and the PoE priority on the port.
