power inline
Use this command to enable inline power and configure maximum power allocation with priority for the powered device
connected to an interface.
Syntax
power inline {[max_milliwatts ]| priority {critical | high | low}}
To disable a device that has been enabled for PoE power supply, use the no power inline command.
Parameters
max_milliwatts (OPTIONAL) Specify the maximum amount of inline power allocation to a powered
device connected to the interface. Range is 440–30000 milliwatts (mWs). The
default value is 30000 mWs.
NOTE: The max_milliwatt configuration is effective only in Static mode.
priority Enter the keyword priority to specify the PoE priority for the powered device
connected to the interface. Default priority value is low.
critical Enter the keyword critical to set the PoE priority level as critical.
high Enter the keyword high to set the PoE priority level as high.
low Enter the keywordlow to set the PoE priority as low.

EMC Networking OS Command Line Reference Guide.
The following is a list of the Dell EMC Networking OS version history for this command.
Version Description
9.10(0.0) Introduced on the S3148.
9.8(2.0) Introduced on the S3100 series.
Usage
information
The power inline [max_milliwatts} command enables inline power supply to an interface. You
can specify the maximum amount of power allocation to a device in max-milliwatts from 440 to 30000
mW. If a specific power supply value is not configured, the default value 30,000 mW is configured as the
maximum power for allocation to powered devices. You can disable the inline power supply to a port using
the no power inline command.
The power inline priority command allows you to specify the power inline priority for an interface
when a power shortage occurs. PoE is removed from ports configured with low priority first, then ports
configured with high priority are disabled. The ports configured with critical priority are the last
ports disabled during a power shortage. When two or more ports are configured with same priority level,
the ports with higher interface numbers are disabled first. For example, if ports 1, 2, 47, and 48 are all
configured with a low priority and there is a shortage of inline power supply, PoE is first disabled on port
48, followed by port 47 and, then port 2. Port 1 (with the lowest interface number) takes precedence
over all other ports and is disabled after all other ports are disabled.
