H3C S7500E Series Ethernet Switches Chapter 1 PoE Configuration Commands
1-30
Description
Use the poe mode command to configure a PoE mode.
Use the undo poe mode command to restore the default.
By default, the PoE mode is signal (power over signal cables).
The PSE supplies power for a PoE interface in the following two modes: signal and
spare.
z In the signal mode, lines in Category 3 and 5 twisted pair cables used for
transmitting data are also used for supplying DC power.
z In the spare mode, lines in Category 3 and 5 twisted pair cables not in use are
used for supplying DC power.
Currently, the S7500E series switches do not support the spare mode.
