Switch Management Commands 2073
The static power management feature allows operators to reserve a
guaranteed amount of power for a PoE port. This is useful for powering up
devices which draw variable amounts of power and provide them an assured
power range within which to operate. Class based power management
allocates power at class limits as opposed to user defined limits.
In the Dynamic Power management feature, power is not reserved for a given
port at any point of time. The power available with the PoE switch is
calculated by subtracting the instantaneous power drawn by all the ports from
the maximum available power. Thus, more ports can be powered at the same
time. This feature is useful to efficiently power up more devices when the
available power with the PoE switch is limited.
The Dell EMC Networking PoE solution also provides a global usage
threshold feature in order to limit the PoE switch from reaching an overload
condition. The operator can specify the limit as a percentage of the
maximum power.
NOTE: PoE commands are only applicable to copper ports.
power inline
The power inline command enables/disables the ability of the port to deliver
power.
Syntax
power inline {auto|never}
• auto — Enables device discovery and, if a device is found using the
method specified by the power inline detection setting, supplies power
to the device.
• never — Disables the device discovery protocol and stops supplying
power to the device.
Command Mode
