DES-3028 DES-3028P DES-3052 DES-3052P Layer 2 Fast Ethernet Switch CLI Reference Manual
config poe system
system.
Parameters
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:
The default setting is deny_next_port.
Restrictions
User Account Command Level – Administrator and Operator
g) deny_next_port - After the power budget has been
exceeded, the next port attempting to power up is denied,
regardless of its priority.
h) 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).
Example usage:
To config the PoE System on the Switch:
DES-3028P:4#config poe system power_limit 185
power_disconnect_method deny_next_port
Command: config poe system power_limit 185
power_disconnect_method deny_next_port
Success.
DES-3028P:4#
config poe ports
Purpose
Used to configure the PoE port settings.
Syntax config poe ports [all | <portlist>] {state [enable | disable] |
priority [critical | high | low] | power_limit [class_0 | class_1 |
class_2 | class_3 | user_define <value 1000-16800>]}
The config poe ports command is used to configure the PoE port
settings.
<portlist> -Specifies a range of ports to be configured or all the
ports.
all – Specifies that all ports on the Switch will be configured for
PoE.
state - Enables or disables the PoE function on the Switch.
priority - Setting the port priority affects power-up order and
shutdown order. Power-up order: When the Switch powers-up or
reboots, the ports are powered up according to their priority (critical
first, then high and finally low). Shutdown order: When the power
limit has been exceeded, the ports will shut down according to their
priority if the power disconnect method is set to deny_
low_priority_port.
Description
Parameters
• critical – Specifying this parameter will nominate these
ports has having the highest priority for all configured PoE
