53-1 config poe system
Description
This command is used to configure the parameters for the POE system-wise function.
Format
config poe system {power_limit <value 37-188> | power_disconnect_method
[deny_next_port | deny_low_priority_port] | legacy_pd [enable | disable]} (DES-3200-28P
Only)
config poe system {power_limit <value 37-370> | power_disconnect_method
[deny_next_port | deny_low_priority_port] | legacy_pd [enable | disable]} (DES-3200-52P
Only)
Parameters
power_limit - (Optional) Configure the power budget of PoE system. The range of value which
can be specified is determined by the system.
<value 37-188> - Enter the power limit value here. This value must be between 37 and 188.
(DES-3200-28P Only)
<value 37-370> - Enter the power limit value here. This value must be between 37 and 370.
(DES-3200-52P Only)
power_disconnect_method - (Optional) Configure the disconnection method that will be used
when the power budget is running out. When the system attempts to supply power to a new
port, if the power budget is insufficient to do this, PoE controller will initiate port disconnection
procedure to prevent overloading the power supply. The controller uses one of the following
two ways to perform the disconnection procedure.
deny_next_port - The port with max port number will be denied regardless of its priority. Note
that if the disconnect_method is set to deny_next_port, then the power provision will not
utilize the system’s maximum power. There is a 19W safe margin. That is, when the
system has only 19W remaining, this power cannot be utilized.
deny_low_priority_port - If there are ports that have been supplied power that have a priority
lower than the new port, the port with the lowest priority will be disconnected. This process
will stop until enough power is released for the new port. Note that if the
