CLI Reference Guide
Use the command to configure power service policy for whole system's usage
under power shortage condition.
The power will not be provided to the new PD connected port regardless of port
priority setting if the unit enters into critical section.
If there are ports that have been provided with power with a lower priority than
the new PD connected port and there comes power shortage, the connected PD
port with the lowest priority will be disconnected. This process will be performed
continuously until enough power is released for the new connected higher
priority port or no available PD port can be disconnected.
non-preemptive.
Global configuration.
The PoE system has a limited power watts referred as power budget. Once the
used power almost reaches the power budget limit, this condition is referred as
power critical section.
The service policy is used to determine the power service behavior as PoE
power system enters the critical section. If the PoE system is configured with
non-preemptive, no additional port can be serviced with power once the PoE
system enter critical section. However if the preemptive mode is configured,
additional port can be powered up with a cross-unit power management as long
as its priority is higher than all other serviced ports.
In the situation of containing units which is not PoE capable in the system, there
will be a message displayed for reminding those units will not take effect with this
command.
This example shows how to configure POE system power service policy as non-
preemptive mode.
You can verify your settings by entering the show poe power system command.
