Setting the PoE Mode on a Port
PoE mode of a port falls into two types, signal mode and spare mode.
z Signal mode: DC power is carried over the data pairs (1,2,3,6) of category-3/5 twisted pairs.
z Spare mode: DC power is carried over the spare pairs (4,5,7,8) of category-3/5 twisted pairs.
Currently, S5100-SI/EI series Ethernet switches do not support the spare mode.
After the PoE feature is enabled on the port, perform the following configuration to set the PoE mode on
a port.
