Chapter 1. Commands for PoE 4

www.qtech.ru

 Default: Disable.

 Usage Guide: With PoE globally disabled, there would be no power output no matter

what the power state of a specified port is.

 Example: Globally disable PoE.

 Switch(Config)#no power inline enable

1.1.4 power inline enable (Port)

 Command: power inline enable

 no power inline enable

 Function: Enable/disable PoE power supply.

 Parameters: None.

 Command Mode: Port Mode.

 Default: Enable.

 Usage Guide: Enabled: Automatically detect PD. In such a state, PSE will automatically

detect and classify a PD, and provide power supply for it according to the classification.

If a PD connection is detected, its specified output power will be satisfied as long as

there is enough available power, after which the corresponding LED indicator will be

updated. Otherwise, the power distribution rules will decide whether or not to

implement this power supply. During a normal power supply process, if PD requires for

an extra power which exceeds the max threshold value, the supply will be cut off and

the corresponding LED indicator will be updated. When the PD is disconnected from the

PSE normally, PSE will stop outputting power supply and update the corresponding LED

indicator.

 Disabled: Disable power supply. With the PSE power supply disabled, no

power will be output regardless of the existence of PD connections,

which means the port will act as a regular Ethernet data port without

affecting data transmission.

 When it is globally disabled, no power supply will be output regardless of the power

supply is enabled or disabled on ports.

 Examples: Disable power supply on ports1, 3, 4, 5, 6.

 Switch(Config)# interface ethernet 1/0/1;3-6

 Switch(Config-Port-Range)#no power inline enable

1.1.5 power inline high-inrush

 Command: power inline high-inrush enable

 no power inline high-inrush enable

 Function: Enable the allowed high-inrush current when nonstandard PD is powered

instantaneously, disable the allowed high-inrush current.

 Parameter: None.

 Command Mode: Global mode

 Default: The allowed high-inrush current is not enabled.
