This switch supports the IEEE 802.3af Power-over-Ethernet (PoE) standard
that enables DC power to be supplied to attached devices over the wire
pairs in the connecting Ethernet cable. Any 802.3af compliant device
attached to a port can directly draw power from the switch over the
Ethernet cable without requiring its own separate power source. This
capability gives network administrators centralized power control for
devices such as IP phones and wireless access points, which translates into
greater network availability.
A maximum PoE power budget for the switch (power available to all switch
ports) can be defined so that power can be centrally managed, preventing
overload conditions at the power source. If the power demand from
devices connected to the switch exceeds the power budget setting, the
switch uses port power priority settings to limit the supplied power.
In the example below, the power mainpower maximum allocation CLI
command is used to set the PoE power budget for the switch. (Range: 37 -
180 watts). If devices connected to the switch require more power than the
switch budget, the port power priority settings are used to control the
