Command Mode
Interface Configuration (ECS4120-28P Ethernet ports 1-24)
Command Usage
â—† The total PoE power delivered by all ports cannot exceed the maximum power
budget of 370W. All the RJ-45 ports support both the IEEE 802.3af and IEEE
802.3at standards. The maximum number of ports which can supply power
simultaneously at the specified levels are shown in the following table.
â—† If a device is connected to a switch port and the switch detects that it requires
more than the maximum power allocated to the port or to the overall switch,
no power is supplied to the device (i.e., port power remains off).
Example
Console(config)#interface ethernet 1/1
Console(config-if)#power inline maximum allocation 8000
Console(config-if)#
