DESCRIPTION
This field indicates whether or not a powered device (PD) is allowed to receive power
from the Switch on this port.
This field displays the power classification of the PD. Each PD has a specified maximum
power that fall under one of the classes.
The Class is a number from 0 to 6, where each value represents the range of power
that the Switch provides to the PD. The power ranges in PoE standards are as follows.
• Class 0 - default: 0.44 W to 15.4 W.
• Class 1 - default: 0.44 W to 4 W.
• Class 2 - default: 0.44 W to 7 W.
• Class 3 - default: 0.44 W to 15.4 W.
• Class 4 - default: 0.44 W to 30 W.
• Class 5 - default: 0.44 W to 45 W.
• Class 6 - default: 0.44 W to 60 W.
Note: You can extend or set a limit on the maximum power the connected
PD can use on a port using the pwr interface <port-list> max-
power <1000-33000> command.
The user-configured maximum power setting will not take effect when
the power-up mode is set to 802.3bt.
When the power-up mode is NOT 802.3bt and the Switch is in
consumption mode, the default maximum power that can be
delivered to the PD is 33 W (IEEE 802.3at Class 4) or 22 W (IEEE 802.3af
Classes 0 to 3).
When the total power requested by the PDs exceeds the total PoE power budget on
the Switch, the Switch uses the PD priority to provide power to ports with higher priority.
This field displays the PoE standard the Switch uses to provide power on this port.
This field displays whether wide range detection is enabled on the Switch.
This field displays the amount of power the Switch is currently supplying to the PoE-
enabled devices connected to this port.
This field displays the maximum amount of power the Switch can supply to the PoE-
enabled devices connected to this port.
