Figure 58: LLDP-MED Configuration

Use the Power Over Ethernet Configuration page to set the maximum PoE
power provided to a port, the maximum power budget for the switch
(power available to all RJ-45 ports), the port PoE operating mode, power
allocation priority, and the maximum power allocated to each port. If the
power demand from devices connected to the switch exceeds the power
budget, the switch uses port power priority settings to limit the supplied
power.

The switch can provide DC power to a wide range of connected devices,
eliminating the need for an additional power source and cutting down
on the amount of cables attached to each device. Once configured to
supply power, an automatic detection process is initialized by the switch
that is authenticated by a PoE signature from the connected device.
Detection and authentication prevent damage to non-compliant devices
(IEEE 802.3af or 802.3at).
This switch supports both the IEEE 802.3af PoE and IEEE 802.3at-2009
PoE Plus standards. To ensure that the correct power is supplied to
powered devices (PD) compliant with these standards, the first
detection pulse from the switch is based on 802.3af to which the
802.3af PDs will respond normally. It then sends a second PoE Plus
pulse that causes an 802.3at PD to respond as a Class 4 device and
