config poe system
Purpose
Used to configure the parameters for the whole PoE system.
Syntax
config poe system {units [<unitlist> | all]} {power_limit <value 37–370> |
power_disconnect_method [deny_next_port | deny_low_priority_port]
management_mode [power_limit | auto]} (1)
Description
This command is used to configure the parameters for the whole PoE system.
Parameters
units <unitlist>
– Enter the switch in the switch stack for which to configure the PoE
system. This number is based on the unit ID assigned to the switch in the switch stack.
The DGS–3426P is the only switch in this series with PoE capabilities.
power_limit
– The power limit parameter allows the user to configure the power budget of
whole PoE system. The minimum setting is 37 W and the maximum is 370W (depending
on the power supplier’s capability). Default setting is 370 W.
power_disconnect_method
–This parameter is used to configure the power management
disconnection method. When the total consumed power exceeds the power budget, the
PoE controller initiates a port disconnection to prevent overloading the power supply. The
controller uses one of the following two ways to implement the disconnection:
•
deny_next_port
– After the power budget has been exceeded, the next port
attempting to power up is denied, regardless of its priority.
•
deny_low_priority_port
– After the power budget has been exceeded, the next
port attempting to power up, causes the port with the lowest priority to shut
down (to allow high
–
priority ports to power up).
The default setting is
deny_next_port
.
management_mode
– Use this parameter to utilize the PoE management mode function
of this switch. The user has two choices:
•
power_limit
– Choose this option to shut down the port if the power limit on the
port exceeds the limit stated by the user configured in the
power_limit
field.
•
auto
– Choose this field to automatically disconnect the power from a given port
when it exceeds the maximum power used, as defined by the PD’s (power
device) power class, stated previously in this section. When a PD is attached to a
port on the Switch, the Power Class is automatically determined. If the PD’s
power class is unspecified or there is an error in determining the power class, it is
given the power class zero (0).
Restrictions
Only Administrator and Operator-level users can issue this command.
Example usage:
To config the PoE System on the Switch:
