â—† When detection is enabled for PoE-compliant devices, power is automatically
supplied when a device is detected on the port, providing that the power
demanded does not exceed the port’s power budget or the switch’s power
budget.
Example
Console(config)#interface ethernet 1/1
Console(config-if)#power inline
Console(config-if)#exit
Console(config)#interface ethernet 1/2
Console(config-if)#no power inline
Console(config-if)#
power inline
maximum allocation
This command limits the power allocated to specific ports. Use the no form to
restore the default setting.
Syntax
power inline maximum allocation milliwatts
no power inline maximum allocation
milliwatts - The maximum power budget for the port.
(Range: 3000 - 30000 milliwatts)
Default Setting
30000 milliwatts
Command Mode
Interface Configuration (ECS4620-28P/52P Ethernet ports 1-24/48)
Command Usage
â—† The ECS4620-28P can supply up to 30W of power for 13 ports (based on
IEEE 802.3at), or up to 15.4W to 24 ports (based on IEEE 802.3af).
â—† The ECS4620-52P/52P-2AC can supply up to 30W of power for 23 ports (based
on IEEE 802.3at) when power is provided from the RPS, or up to 15.4W to 48
ports (based on IEEE 802.3af).
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)#
