A PoE-enabled S5100-SI/EI switch has the following features:
z As the PSE, it supports the IEEE802.3af standard. It can also supply power to some PDs that do
not support the 802.3af standard.
z It can deliver data and current simultaneously through data wires (1,2,3,6) of category-3/5 twisted
pairs.
z The PSE processing software on the switch can be upgraded online.
z The switch provides statistics about power supplying on each port and the whole equipment, which
you can query through the display command.
z The switch provides two modes (auto and manual) to manage the power feeding to ports in the
case of PSE power overload.
z The switch provides over-temperature protection mechanism. When the internal temperature of the
switch exceeds the PoE protection temperature, the switch disables the PoE feature on all ports for
self-protection; When the internal temperature of the switch drops below the PoE restoration
temperature, the switch restores the PoE settings on all ports.
Table 1-2shows the PoE protection
and restoration temperatures of switches.

z The switch supports the PoE profile feature, that is, different PoE policies can be set for different
user groups. These PoE policies are each saved in the corresponding PoE profile and applied to
ports of the user groups.
